Vinyl calendering systems incorporate scanning basis weight and true thickness measurements with optional stationary sensors. Accurate profile measurement that is independent of roll condition and line speed is important.

The IPlus! Measurement and Control System for Vinyl Calendering combines advanced sensor technology and powerful software in an intuitive, easy-to-use system to provide high performance and a low cost of ownership.

The Thermo Scientific™ SYNCRO-SCAN roll runout compensation synchronizes the scanning measurements to the roll rotation, eliminating short-term machine direction roll variations from profile measurement. This produces fast, responsive, accurate profiles. 

Two-zone calender control improves product quality with side-to-side roll gap adjustments to hold product profiles flat. Three-zone calender control for either cross axis or roll bending controls the center zone, assuring flat final product profiles. Nominal control adjusts product average to a fixed target.
