Dependency on PMC suppliers

Producing paper is a capital-intensive industry. Financial experts dictate how business is run to a large degree. Reducing costs is a key responsibility for a Production Manager. Rightfully so, we won’t argue with the need for cost reduction. What we do need to address is the TYPE of cost reduction that will turn out costly for our future.


The Pros Of Limiting The Number Of Suppliers

A way to reduce costs is to pay lower prices for larger purchasing volume per supplier. Automatically you reduce the number of suppliers for the papermaker.

For papermakers it is convenient to have only one or two paper machine clothing suppliers, because once they are familiar with the papermaker’s situation, they do not only deliver the clothing, but they can also take care of installing felts and fabrics, do regular service measurements, supply consignment stock, troubleshoot and advise on paper machine settings.

The machine clothing supplier won’t object to being the single preferred supplier for a papermaker. It means lower acquisition costs and business continuity when large volume purchases are guaranteed. Plus, with experience of the papermaker’s machine, it becomes much easier to design good felts and fabrics.

Production disturbances can be solved faster through knowledge sharing, especially when you are familiar with each other’s machines, materials, processes and procedures. Not to mention the smaller communication gap that exists between the people of 2 companies that are comfortably working together.

But we all know that innovation doesn’t happen in our comfort zone…



The Dangers Of Limiting The Number Of Suppliers

The capital gains of comfort, efficiency and (large volume) cost reduction are short-term. It is important we see the whole picture to understand the long-term consequence that will inevitably become shorter-term when we near the paper industry’s future.

Having only one or two paper machine clothing suppliers is bringing several risks for both the papermaker and the machine clothing supplier.



The papermaker has a big dependence on their supplier. If something happens (service engineers leaving, delivery problems) they have little to no alternative. Also, every paper machine is unique. It takes years to understand the specific complexity and peculiarities of an individual machine, and then still… you’re never sure. Properties change over time. Realistically, a papermaker cannot expect a supplier to fully understand their machine and I believe it is the Production Manager’s responsibility to monitor and collect data on a machine’s performance and improvement potential.


Failure To Innovate

A preferred Paper Machine Clothing supplier has an enormous competitive advantage over candidate suppliers who do not have the knowledge of and experience with the specifics of the paper machines of their potential customer.

Being in its comfort zone, a paper mill will not look for new PMC suppliers or innovative solutions when the PMC supplier keeps its customer, the papermaker, satisfied enough. Without the pressure of an immediate competitor, reducing risks becomes the ambition for both the papermaker and PMC supplier. As a result, the development of successful new Machine Clothing technology is slowed down.


On A Wider Scale

As we all know, a mindset to reduce all risks is not conducive to the innovation our industry needs.


We may live of paper, but the rest of the world doesn’t

On a global scale, paper must compete with many other materials, media and mindsets.

  • Graphic paper competes with electronic media.
  • Banknote paper competes with polyester (just check the Canadian Dollar bills).
  • Cigarette paper competes with the mind of a health-conscious consumer.
  • (Recyclable) Plastics can be a worthy alternative for companies who need strong, lightweight and less flammable packaging materials.
  • We may consider Japanese toilets, with water cleaning and a comfy hot air dryer, as too futuristic, but didn’t we think the same about passenger jets or computers in the past?


“Don’t settle for the status quo, when innovation opportunities knock on your door” – Marcel Lensvelt, CEO & founder of Feltest Equipment BV

Any paper mill that wants to stay ahead of current and future competition needs to innovate. Don’t forget that paper mills are not only competing with each other—on a global scale—but are also competing against other materials and alternative solutions to paper.

Paper mills must find new ways to greatly improve the output and performance of their machines. In advanced quality. In reduced cost. In growing volume. In increased worker’s safety, and more.

However, in getting a solid short-term return on investment, the paper industry is playing it safe. Due to large sums of money and the perceived risk involved, the general rule is to follow a conservative strategy. It’s a deadly strategy in the long run, jeopardizing the future of the whole industry.

Fortunately, all hope is not lost. To be continued soon with part two about “What to do, and how…

Again, don’t push too hard…


In two previous articles I reflected on problems related to too high or too low tension in forming fabrics.

In this article, I want to focus on the (im)proper use of the mechanical tension gauge.

The basic working principle of any mechanical tensometer is simple: a spring is pushing the sensor bar into the fabric and the actual travel of the sensor bar is converted into a tension reading on the dial.



In a slack fabric there is little resistance from the fabric against the push force of the spring, so the sensor bar travels relatively far into the fabric. On the other hand: a more taut, or tensioned, fabric is ‘pushing back’ against the spring and so reduces the travel of the sensor bar into the fabric.

You can imagine this is a delicate game between relatively small forces in the fabric and the instrument’s spring. And then: there comes the operator with 100x more muscle power in his right arm (or left arm for that matter). To get an accurate measurement with a mechanical tensometer, the trick is to let the forces in the instrument and the fabric do their work – the big, strong human should try not to interfere.

In other words: use as little force as possible when holding the instrument onto the running fabric. The more you push, the more tension you create yourself and that tension will be measured too! Result: a test value that is much higher than the actual tension in the running fabric.

Over the years I have learned that this way works best:



  1. First let only one edge of the instrument gently touch the fabric.


2. Then rotate your wrist so that the other edge touches the fabric too.


3. After both edges simultaneously touched the fabric, immediately move the instrument of the fabric.

The drag pointer of the TensioMaster will hold the highest reading for you, so you can safely read the dial outside the machine’s run.

Repeat the measurement two times and you’ll see that the instrument gives reliable and accurate results – provided the instrument is well maintained. If your tensometer is in shady condition, I would like to point out the Feltest whitepaper on poorly maintained tensometers.

Don’t push too hard…

In my previous blog, we reflected on 2 major causes and the resulting problems of fabrics running with a tension that is too high.

In this blog article, I want to focus on the signs and consequences of forming fabrics running at a tension too low for optimal performance of your paper machine.

One of the causes of low tension is improper use of the tension gauge.

Illustration – Feltest TensioMaster

Due to the measuring principle of a mechanical tensometer, it is more difficult to accurately measure a slack fabric than a high-tensioned fabric. Many operators use too much force during the measurement, simply because they learned this gives them repeatable test results. Unfortunately the repeatability has no relation to the accuracy of this measurement…

Now that it’s clear why many papermakers push the instrument too hard, what are the consequences? The push itself puts additional tension on the part of the fabric where tension is measured. The result is a read off tension value that is significantly higher than if the fabric were still running ‘free’ (without a tension gauge pushing it down).

So if you want the fabric to run on 6 kN/m and you measure 6 kN/m, you’re done, right?

Not quite so.

In reality the wire could be running at 5 or even 4 kN/m. If you knew the real value is much lower, you would surely increase the machine tension.


Let me point out some serious low-tension problems:

Slip between drive rolls and fabric
Low fabric tension allows slip between the drive rolls and the fabric. This slip will wear out the fabric faster. But there is a much bigger problem…

Reduced machine output
A common reaction when slip occurs is to reduce the vacuum on the suction boxes. This will cause a decrease of dewatering capacity in the forming section, and thus reduced machine output. This is by far the most important problem caused by low forming fabric tension and should be avoided at all times.

Damage to dewatering elements
Dewatering elements should have sharp lead-in edges to ‘cut’ the water hanging on the roll side of the fabric.
Slack fabrics, carrying a high load of water and fibers, tend to hang in between dewatering elements. Not only will this cause accelerated wear of both the fabric and the sharp lead-in edges of the plastic or ceramic foils. As a consequence, the dewatering efficiency of these elements is also strongly reduced, leaving the papermaker with less dry content and increased costs for replacing dewatering elements.

Guiding problems
Guiding rolls have a problem with slack fabrics. As can be read in our whitepaper Solving Guiding Problems on Forming Fabrics, the guiding roll needs a certain friction between fabric and guiding roll to guide the wire in the right direction. When the tension is too low, extra manipulation and corrections of the guiding system are needed, creating extra fabric wear.
The before mentioned problems – drive slip, hanging between elements and extensive guiding – all have one thing in common: they lead to extended fabric wear. Obviously this causes extra costs for replacement fabrics and production costs.
But faster fabric wear involves another risk…

Strong wear forces working on the fabric will cause the yarns on the roll side of the fabric to show fraying or wear burrs.
Shown at below picture:

The frayed fabric will partly block the dewatering channel and limit its dewatering capacity. You also run the risk of congesting the dewatering channel in the fabric as fiber particles get ‘hooked in’ by the fray.

Strong fabric wear is a killer for your machine output, where the lost production due to poor dry content competes with the lost production due to an increased number of stops to replace fabrics.


So what can you do?

First, you need a reliable instrument, like the Feltest TensioMaster, to measure the fabric tension to know when to tension your fabric and how much you need it to tension.

Then, in order to get an accurate measurement with your mechanical tensometer, you need to use as little force as possible. Gently push the instrument onto the running fabric so that the leading edges barely touch the fabric and then immediately move it back and read the dial.

Never underestimate the importance of using high quality precision tools in the right way to provide you with accurate performance values, like crucial fabric tension.

Your periodic investments for regular service or timely replacement of measuring instruments far outweigh the enormous costs that are likely to occur when you don’t.

Discover the cause and effect of measuring low tension values.

Most paper mills use a mechanical tension gauge to measure the tension of Paper Machine Clothing, mostly forming fabrics. When this instrument is not in a perfect condition, it can cause serious problems in running your papermachine.
The 2 most common defects on mechanical tension gauges are:

  1. a worn sensor bar
  2. a leaking bellow, causing internal friction

working principle of a mechanical tension gauge

Illustration – working principle of a mechanical gauge


1 – worn sensor bar
If a sensor bar is worn down for several millimetres, it will push further downwards by the defined spring load, thus showing lower than the real tension value. (The higher the fabric tension, the more the bar is pushed upwards.)

2 – leaking bellow
Aging rubber material and the moving spindle will wear out the bellow, making it no longer watertight. Splash water will cause internal corrosion, giving the spindle extra mechanical resistance during measurements. The fabric will not push the sensor bar upwards as easily as it should, thus showing lower values.

Both defects have the same effect on the measurements:


The gauge will show a tension value that is TOO LOW.

And you will have no idea.

“Everything looks fine to me”
In many paper mills the tension gauges are considered to be functioning so long as… the needle (the sensor bar) is still moving!


Meanwhile operators are basing their adjustment decisions on values that are too low. Unknowingly.

Because what happens if you adjust your fabric tension based on a measured tension value that is too low? Right, you will inadvertently increase the tension of a running fabric that may have a tension that is already too high.


High fabric tension cause serious problems:

Tearing of forming fabrics
Highly tensed running fabrics are prone to tear, or break. You want to avoid the cost for unplanned downtime and replacement of torn fabrics.


Damage to guiding rolls
High tension fabric can lead to excessive bending and dislocation of guiding rolls that keep a paper machine fabric running straight. Excessive mechanical stress can lead to metal fatigue and damage to bearings and jamming of the system. Realize that you are also putting your staff at risk because accidents are more likely to happen when moving parts jam or dislocate.


Low paper quality
The bending of rolls due to high tension will cause the running fabric to move forward in the center of the machine’s width. This changes the fabric structure, its dewatering channels and hence its dewatering properties. This inconsistent structure negatively influences the quality of the paper output. I don’t have to tell you why this is bad news.


High tension causes waviness of a paper machine fabric. Apart from the resulting runnability problems, it will also have a negative effect on paper quality output.


Consult our  whitepaper Poorly Maintained Tension Gauges May Cause Severe damages for comprehensive details on the negative effects of high tension.

If these negative effects are the result of poorly maintained tension gauges, they can and should be avoided by any papermaker in their right mind.


Whatever it takes.
And the good news is… it doesn’t take that much.


The Feltest Tensiomaster

Illustration – Feltest TensioMaster


As you should never underestimate the cost of a malfunctioning tension gauge, you should never underestimate the value of a quality fabric tension measuring instrument that will always provide you with accurate performance numbers.

Your periodic investments for regular service or timely replacement of this precision measuring instrument far outweigh the enormous cost that are likely to occur when you don’t.

BLOG: NIP DEWATERING and felt caliper

Back in the 1980’s the performance of press felts was mainly judged by looking at the sheet; nobody really knew what was happening inside the felt once it was running. With the introduction of nip dewatering the felt designers needed more information.

A thick, bulky press felt is not a good thing. At least, not when you are running with nip dewatering. In this blog post I tell a bit more about the relation between nip dewatering and Feltest.


Nip dewatering and felt Caliper


The Caliper Profiler was Feltest’s first product ever. Actually, it was the spark that started the founding of Feltest as a company!

Back in the 1980’s my father, Nick Lensvelt, was a felt application engineer for one of the world’s leading Paper Machine Clothing manufacturers in Europe. In those old days the performance of press felts was judged only by looking at the sheet. After installation, felt properties were no longer measured or monitored; nobody really knew what was happening once the felt was running.


The introduction of nip dewatering

It were also the days that grooved press rolls were introduced: the introduction of nip dewatering! With nip dewatering a new question arose: why do felts have a startup or break-in period? My father has a very analytical background and not only wanted to see WHAT happened with the felt, but he also wanted to understand WHY. The only tools available, the Scanpro© Jetmem and the vacuum level on the Uhle box, where not giving him the information he needed to solve this puzzle.


The first in measuring felt thickness on the fly

He designed an instrument that could accurately measure the thickness of a running felt. With its pistol-like handgrip it drew quite a bit of attention.



With the new information the instrument supplied, it became very clear that the mid-nip caliper is an extremely important felt property. Thinner felts with an optimized base weave had less flow resistance in the mid-nip and once the water was out of the nip, rewetting was no longer an issue. These findings resulted in thinner felts that generated more nip dewatering, less contamination, shorter break-in periods and higher sheet dryness. The productivity of paper machines with nip dewatering increased considerably!


In the early nineties Nick Lensvelt accepted a position with another PMC manufacturer. This new company had no intention to start manufacturing measuring gear as well, so it was agreed that Nick Lensvelt would manufacture it himself and the PMC manufacturer would buy it from him. With his experience from the first model, Nick started sketching an improved version and asked me to do the engineering work. My father and I still had to think of a name for our new established company. I didn’t lose much sleep over that: the instrument is developed for a “felt test”, but then a bit more stylish, so “FelTest” is what it became!


measuring felt


1992: the first Feltest Caliper Gauge

In 1992 we supplied the first instrument to this European PMC supplier and, as they say, the rest is history. Nowadays Feltest has sold hundreds of pieces of the classic Caliper Gauge and today’s Caliper Profiler all over the world. Nick Lensvelt’s bright idea, back in the eighties, for sure contributed to the success of the concept of nip dewatering felts. It enabled him and many other felt application engineers over the world to study the effect of felt compaction and to differentiate compaction from contamination (for more details on this, check out the whitepapers or watch my Papercon presentation).


The Caliper Profiler as foundation of quality measurement today

For me personally, designing the caliper gauge in 1992 was the start of successful cooperation with my dad that lasted over a decade until he retired. It was the start Feltest Equipment BV, today offering a wide range of innovative handheld products to satisfied customers in over 70 countries.


It is Feltest’s mission to drive innovation in Paper Machine Clothing to the benefit of papermakers and PMC suppliers. The measuring gear of  Feltest enables papermakers to make fact based decisions on their Machine Clothing and to get the best possible performance of their press felts and forming fabrics!


This makes the Caliper Profiler for sure the first Product if you want to increase nip dewatering, reduce the break-in period or save on felt washing agents.

Nip dewatering and felt Caliper

How to determine the right Fuji Film type?

Our Fuji pressure sensitive film is extremely helpful when investigating the press load distribution of a paper machine. The film helps you to identify misalignments, crowning deviations and find roll cover problems like delamination or soft/hard spots. Feltest offers several sensitivities of Fuji Film, but sometimes users find it difficult to select the correct type. Maybe this article can shed some light…


The Fuji pressure sensitive film comes in several pressure ranges, I guess that makes sense. Fuji uses the ISO unit for pressure, being MPa (Mega Pascal). Unfortunately there are very few paper machines that indicate their press load in MPa, so the question is: how do I convert my press load reading into MPa?


The unit MPa equals a to force of 1 N on an area of 1 mm2, or 145 psi for our North American customers. Most paper machines indicate a linear pressure for their press nips, for example 100 kN/m or 561 pli. This is a rather theoretical unit as it is assuming that the press load force is working on an area line with a certain length (a meter or an inch) and an infinite narrow width.


In reality your press nip does not have an infinite narrow width. On the contrary: depending on roll diameters, roll cover materials and the applied load it can be between 5 and >25 mm (1/5 to > 1”). The softer the roll cover materials, the wider the nip will become. As a papermaker you should be able to get more detailed information from your roll cover supplier or the machine builder who supplied the press.


A practical example:
1. Read the normal press load, under running conditions, in kN/m. For example: 100 kN/m
2. Take the width of the machine, or more precisely: the length of the contact area of two mating the press rolls. In this example we’ll take 5 m.
3. When you multiply these you will get the total force in this nip: 100 kN/m * 5 m = 500 kN.
4. This total force works on an area of 5 m long and several mm wide. If we have a hard nip, like steel on granite, it is estimated to be 8 mm wide.
5. Now we get to the true pressure in the nip: 500,000 N works on an area of 5000 x 8 = 40,000 mm2 which equals 12.5 N/mm2 or 12.5 MPa.
6. In this example the Fuji film with medium sensitivity (MS or MW) with a range of 10 to 50 MPa could be used.


One important note: on some older machines the press load is indicated in a pressure unit, like bar or psi. In almost every case this refers to the air or oil pressure in the bellows; it has no relation to the contact pressure between the two mating rolls! In situations like this you first need to convert the bellow pressure to a linear press load and then go through steps 1 to 6 above.


I hope the above has been helpful!


Kind regards,

How much life is REALLY left in your felt?

At Feltest it is our goal to provide paper mills with knowledge and easy-to-use solutions to improve the performance of their paper machine clothing.

Today, I’d like to focus on press felts and felt permeability in particular, because it is the most important indicator for overall press felt quality. I like to view press felts as the lungs of the paper machine. Like a runner who is in perfect breathing condition to run a marathon, a press felt with perfect permeability sets the stage for optimal runnability of the whole paper machine. But as much as I like to say ‘perfect permeability’ because of the initial rhyme, perfect permeability does not exist for a press felt.

Instead of perfect permeability – I said it again – we have to talk about the best possible felt permeability because it is always a compromise between re-wetting and dewatering. Felt permeability is also highly dependent on local circumstances, such as press and roll cover design, speed, stock quality, air humidity, contamination etc.

In any event, you want to prevent the problems that occur when a felt is either too open or too dense. For example, the problem of re-wetting at the nip exit when the felt is too open or water ripping the sheet when it enters a felt that is too dense.

But I don’t want to bore you with permeability problems today. I want to talk about solutions. I want to relieve you of your headache of not knowing if your felt permeability is as good as it should be.



Let me start with a WARNING.


Don’t use the CFM values on a manufacturer datasheet for comparing felts or deciding on felt designs. The datasheet is good for quality assurance of the manufacturer, but it has no real use for paper makers.
You simply don’t want to base your decisions on standards that come from a laboratory simulation. You need to measure where the action takes place – at the press felts in your running machine. I have good news for you, because measuring actual felt permeability is neither difficult nor expensive if you have the right tools.


The Feltest Airspeed/2 is a handheld tool that helps you quantify your felts operational permeability by accurately measuring the air velocity through the felt at the Uhle box while your machine is running. The Airspeed/2 is designed to function in the rough, corrosive environment of paper mills.



Being able to measure without unnecessary downtime is key to operational efficiency and cost savings. Of course the airflow is not the only parameter to judge the permeability of press felts. You need to include measurements on the applied vacuum, the caliper of the felt and the water content. If you are interested, you can read more (technical) details about the factors that determine felt permeability quality in our white paper on correct felt permeability.


The importance of measuring on a daily basis
While the Airspeed/2 is an ideal monitoring tool to ensure the quality of your press felts still meets your requirements, I want to point out another important thing.

As a papermaker you can avoid production loss and achieve better operational results by measuring felt permeability on a regular basis.

Regardless of the tools or suppliers you choose to work with, learning from objective data for all machine conditions will accelerate your knowledge of what works best in a situation that is relevant for your paper mill. When you measure at regular intervals, for instance every day at 9 AM, you get the data you need to choose the most appropriate action before the machine itself lets you know by its poor runnability.

I don’t want to see you replace your press felts according to a pre-set schedule, only to discover that you had 8  days of life left in your felt. Neither do I want your felt to break because you failed to detect a permeability problem indicating that something was seriously wrong.


‘The best decisions are made on REAL independent data.’


How much money you will save by measuring daily, will depend on the specifics of your situation. But if you look at all the different instruments, felt measuring tools have the best payback value for a paper mil. The Airspeed/2 is no exception. For instance, if you can prevent only one breakdown, you earn back your investment THREE times or more. In just 20 minutes.


Ownership versus supplier service

While papermakers still appreciate the efforts and knowledge shared by experienced service engineers, I continue to observe that the attitude towards free service measurements from paper machine clothing suppliers is shifting towards a more independent position.

Mills from groups like Domtar, PCA and UPM are already doing several standard/daily measurements themselves while calling in the suppliers service engineers for more complex analysis.

I believe what is in the best interest of a paper mill, is also in the best interest of a felt manufacturer. Think of it this way: Felt manufacturers that share our commitment to continuous improvement will only welcome independent data that gives them accurate information about the real quality and durability of their felt press under real conditions in the paper mill.


‘How could it be any other way?’


As an independent expert on measuring instruments, Feltest not only provides the tools, we help you work with and understand the measured data and share relevant best practices of the paper making industry. That is why Feltest products are used worldwide by both paper manufacturers makers and paper machine clothing manufacturers.


Don’t hesitate to contact me if you have questions about the Airspeed/2 or if you want to explore other operational and financial benefits for your paper making facility.


Kind regards,

The operational advantage of being cool

I asked Mike, Sales manager at Feltest, to write something about his latest sales success. He was more than happy to tell me about his new connections with Japan. So this is what happened.


In close cooperation with our trusted manufacturer of the Hydrogel ™ BodyCooling vest and Feltest sales representative Mr. Toshimichi Hashimoto from the company IGT Testing Systems K.K. in Chiba-ken, we have sold 1.000 Feltest BodyCooling vests to the Japanese Paper mills of OJI Paper, a business line of OJI Holdings Cooperation.


The journey started with Mr. Hashimoto showing some product samples of the vests to the decision makers at various OJI Paper mills.
Seeing is believing. No, testing is believing! After testing the Feltest BodyCooling vests, the OJI Paper mills were more than convinced that the benefits of the BodyCooling vests would contribute to a safer working environment for the paper machine operators in their factories.


They were over the moon and experienced immediately the benefits:
1. Less dehydration; better concentration
2. Simple to activate and reusable many times
3. Brings cooling for a full working day; remains in standby for days!

Of course there are much more reasons to use the body cooling vest. Let me point them out for you.
Working in or around hot paper machines is dangerous for both the production and maintenance crews; safety is a HOT topic. Prevent heat stress situations and wear an iced vest!


Heat stress, disturbed balance
Extreme heat conditions disturb the balance in the human body: heat causes dizziness, dehydration, lower endurance levels and concentration loss; all serious health and safety risks. The Feltest BodyCooling vest contains a patented hydrogel that uses body heat to evaporate water; this effectively cools down the body.



Heat Stress & Safety
Avoid unnecessary heat stress during unplanned downtime, feeding the paper tail, working at hot positions. The Feltest BodyCooling vest provides effective cooling for a full working day. After activation, the vest remains in standby (when stored in a refrigerator) for about a week. Instant cooling when you need it!
Please contact Sales Manager Mike Peeters for more information about the Feltest BodyCooling vests and how to buy!

I wish you a warm summer with lot’s of cooling with our body cooling vests!
