For a system maintenance engineer, identifying potential nip roller problems can be difficult and time-consuming.
Produced by Sensor Products of New Jersey, EZ-NipR is a thin colour-changing pressure-activated paper.
It is claimed to be an easy and efficient troubleshooting tool that can quickly detect problem areas on nip rollers.
It determines the actual working, static, nip width between two mating rollers.
The paper immediately changes color upon the application of pressure, enabling the user to easily analyse and 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 roller pressures accordingly to achieve the proper nip alignment.
EZ-Nip is said to be an 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 and can be used by just one person.
