Pressure-activated paper checks nip rollers

A Sensor Products product story
Edited by the Engineeringtalk editorial team Jan 12, 2004

EZ-Nip is an easy and efficient troubleshooting tool that can quickly be put to the task of detecting uneven nip rollers in web-based conveyance machinery.

With any web-based conveyance machinery, uneven nip rollers cause web-handling waste and yield deficiencies.

Nonuniform nips usually lead to wrinkles, web breaks and other troubles.

For a system maintenance engineer, identifying these little problems with big consequences can be difficult and time-consuming.

EZ-Nip, a thin colour-changing pressure-activated paper, is an easy and efficient troubleshooting tool that can quickly be put to the task of detecting problem areas.

EZ-Nip determines the actual working, static, nip width between two mating rolls.

The paper immediately changes colour on the application of pressure, enabling the user to easily analyse/measure the nip "footprint" (nip width) both visually or, for more intense scrutiny, with a ruler or micrometer.

This measurement then allows the technician to adjust roll pressures accordingly to achieve the proper nip alignment.

EZ-Nip is an extremely economical and practical solution for determining proper crowns, roll parallelism and alignment, and symmetrical loading.

EZ-Nip is a self contained single sheet system making it useable by just one person, and can easily be encased for waterproofing purposes.

EZ-Nip is strictly designed for measuring nip width.
