Operators of rollers, laminators, coaters, and printers with rolls under 39" (1 meter) in length can get instant spot readings of nip width using P-Nip, a new tool developed by Sensor Products Inc. of Madison, NJ, USA.

The handheld portable electronic device allows the capture of nip readings at multiple discrete locations across the roller sets’ face length (cross direction) as determined by the user. It is designed for nips that are 0.0625" to 0.5" (1.6 to 12.7 millimeters). Similar in size to a PDA, P-Nip consists of an LCD display with a small replaceable sensor finger that extends from the top. Recording the spot values simply involves inserting the sensor finger into the nip. P-Nip’s memory allows for storage of readings for later comparison and evaluation.

“Printers, converters and manufacturers of other processes where webs are conveyed between rolls have long been seeking an inexpensive and portable means to quickly measure nip,” says Jeffrey G. Stark, CEO of Sensor Products. “P-Nip directly addresses this need.”
