Sensor Products' Nip Analysis While Rollers Moving

Sensor Products has released its new real-time nip analysis tool F-NipR (Flying Dynamic Electronic Nip Analysis System).

Sensor Products has released its new real-time nip analysis tool F-NipR (Flying Dynamic Electronic Nip Analysis System).

For the first time, claims Sensor, technicians can now measure nip width as the sensor chain passes through the nip while the rollers are rotating at jog speeds.

Since it reveals roller skewing, inaccurate roll alignment, and crown deficiencies, F-Nip is a valuable process control tool for any web-based production environment, the company believes.

Any of these problems can result in uneven processing, wrinkled or mottled products, compacted sheets, excessive sheet breaks and blackening during calendering.

Nip products group manager Madelene Glomsten said: "Dynamic nip tools are particularly beneficial for rollers with interlock systems or when the cover material takes a set from static impressions.

Combining the advantages of Pressurex with E-Nip's real-time electronic analysis, F-Nip provides the ability to measure nip width while the sensor chain is riding on the felt (or other substrate) as it passes through a single nip.

This represents a situation as close as possible to the actual run condition.".
