Sigma-Nip®

What people are saying about Sigma-Nip^® …

“Sigma-Nip^® has come a long way from concept to a reliable, easy to use nip profile measuring tool. It has successfully bridged the gap between conventional carbon paper impressions and the first generation of electronic nip devices. Being able to save and review the entire real-time data from nip closing to nip opening is extremely useful, however, the ability to correlate accurate nip width data to roll deflection is an exceptional benefit.” – Mike Stoltz, Metso Paper USA

“Sigma-Nip^® is an extremely helpful tool for troubleshooting in printing presses and has saved my colleagues and I significant amounts of time. It allows us to assess what is happening where the actual printing takes place and quickly get to the source of the problem. This is a new tool for us and the industry, but I foresee more and more printers starting to use this system as people begin to see its advantages.” – Don Jordan, Abitibi Consolidated

Sigma-Nip^® – an electronic nip analysis system, calculates and records nip width at multiple points across your rollers face length in real-time with unprecedented speed, accuracy and repeatability. The new Sigma-nip® system is not only more accurate, but can handle higher pressures than ever previously attainable.

Sigma-Nip^® presents a revolution in quality control. Now, for the first time ever the technician is able to accurately, efficiently and economically measure roller profiles and alignment condition. Sigma-Nip^® consists of a series of thin-film resistive ink pressure transducers on a carrier sheet. As this carrier sheet is loaded in between your rollers the Windows based software assimilates the readings into easily interpretable graphical images – all in real-time.

What Is Sigma-Nip^®

Sigma-Nip^® consists of a series of sensor elements that are placed in between two contacting rollers. Immediately upon closing of rolls, the sensor begins recording precise nip width measurements allowing you to instantaneously determine whether your rollers are aligned properly and are squeezing together sufficiently. Sigma-Nip^® is a real-time system. What that means is that your roller adjustments can be made WHILE the sensor is actually in the closed (non-rotating) nip. This allows for unprecedented flexibility and speed.
