Easily measure the nip 'footprint'

Non-uniform nips usually lead to wrinkles, web breaks, and poor sheet profiles. Feltest Carbon Paper easily determines the static nip width between two mating rolls, helping you to identify nip deviations like:

Uneven load

Incorrect crowning

Misalignment

How it works

Feltest’s carbon paper is a thin color changing pressure activated paper. The paper immediately changes color upon the application of pressure, enabling the user to easily analyze/measure the nip ‘footprint’ (nip width) both visually or, for more intense scrutiny, with a ruler or micrometer.

 

How to use Carbon Paper for Nip Impressions

  1. Cut to size. For the best analysis, it is advised to use a strip over the full length of the nip.

  2. Prepare for use. If the surroundings are very wet, pack the Carbon Paper in plastic foil. Then place it on one of the rolls with some tape.

  3. Close and open the nip. When the minimum pressure is reached, the Carbon Paper turns dark.

  4. Take it out and analyze the nip width.
