BLOG: BEWARE OF LOW FABRIC TENSION

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…

Fraying
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.

Feel free to contact me or the other Feltest team members to help you ensure that your paper machine is running as smoothly and profitably as possible.

 

Keep on innovating!

BLOG: YOUR FABRIC TENSION IS TOO HIGH – WITHOUT YOU KNOWING IT

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.

 

Waviness
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

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

NIP DEWATERING ACCELERATED BY THE CALIPER PROFILER

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!

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!

CaliperProfiler

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,

 

Marcel Lensvelt

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!

How to determine if your press felt needs replacing

In the Netherlands we have a saying, ‘meten is weten’, which literally translates to ‘measuring is knowing’. I guess we Dutchies like to analyze before we act. And basically, it says it all when it comes to the maintenance of your paper machine and its components.

While I consider press felts to be the most complicated piece of machine clothing there is, measuring its permeability doesn’t necessarily have to be. It doesn’t even have to be expensive for that matter. Determining what course of action to take when you’ve discovered something’s wrong? That’s something

Our product of the month: the AirSpeed/2 monitors the permeability of the press felts in your paper machine. The AirSpeed/2 will tell you whether the felt is too open, too dense or just right. We won’t bore you with the technicalities. We’ve got a handy brochure about the AirSpeed/2 for that.

measuring felt

Back in the USA, up to Panama

It’s always great to visit ‘the States’, this time to give a presentation at the Papercon conference (in Charlotte, NC). The conference is the biggest event in North America. My trip started quite stormy and it was not Stormy Daniels.

No! It was my first tornado. What a force of nature, very impressive. After quick adjustment to the climate I headed straight to the conference hall. Next time I really should plan extra time for some site seeing, the area is beautiful. The conference hall looked as you would expect: solid and well equipped. Entering the building, there was a big area for booths and more than 50 adjacent rooms for presentations. This substantial amount of space is needed, because the comprehensive program contained more than two hundred non-commercial presentations and technical meetings. This is what makes the Papercon conference really interesting: openly sharing available knowledge amongst peers.

 

 

A new trend?
During the exhibition hours, when I was at the Feltest booth, I met interesting people from the American paper industry. It seems that the attitude towards free service measurements from Paper Machine Clothing suppliers is slowly shifting towards a more independent position. Papermakers still appreciate all the efforts and knowledge they receive from the experienced service engineers, but at the same time they also realize that “there ain’t such thing as a free lunch”. Several mills from groups like Domtar, PCA and UPM are already doing several standard measurements themselves and call in the supplier’s service engineers for more complex analysis. This is a trend I fully believe in – not completely coincidentally it was the subject of my presentation at Papercon 2015.

Close to the end of the event, I was able to present my paper on judging the felt permeability on running paper machines. In this presentation I made my case that as a papermaker you can avoid production loss and achieve a better operational result by measuring felt permeability on a regular basis. With the Airspeed and the Caliper Profiler we offer specific solutions to support these objectives. If you were not there, you can watch my presentation here. If you have any questions or remarks, please share your thoughts with me!

Share your felt related challenges and watch the presentation for free?
From June 20th to 22nd I will be presenting the same whitepaper I presented in the US on judging the felt permeability during the Latam Paper event in Panama City. It is a new type of event of in total two days, focusing on papermakers from all over Latin America with technical presentations.

Check the presentation I gave earlier and let me know if you recognize my observations in your production environment. It would be great if you would share your specific challenges and any additional comments with me. It would enable me to use new and actual cases in my next presentation. Of course I will reach out to you and give personal advice to return the favor.

 

Attending the Latam Paper event is only possible through invitation – if you are a Latin American papermaker and you would like to attend, just contact me through email: marcel.lensvelt@feltest.com
