FUJI AND CARBON PAPER
Non-uniform nip loads often lead to many problems, like sheet profile deviations and poor machine runnabillity. Nip load irregularities can cause costly replacements of felts and roll covers.
Feltest Carbon Paper
Carbon Paper determines the nip width between two static rolls. Carbon Paper changes color after closing the nip shortly, leaving behind a nip “footprint”. It is an economical solution for determining proper crowning, roll parallelism and alignment, and symmetrical loading.
Fuji Pressure Sensitive Film
The pressure sensitive film from Fuji gives more information than just the “footprint” of the Carbon Paper; it also quantifies the local press load. The higher the load, the more intensely the film will color. This is very nicely shown in this picture of a suction roll.
Advanced Analysis of Fuji Film
The exact interpretation of the Fuji Film can also be automated by a scanner and dedicated optical software. This analysis instrument reads and interprets nip width and nip pressure data automatically. The result is an easy to use chart, containing both the nip width and the load.
