Technidyne has experience selling and servicing the Tapio RQP in North America. Here are some more illustrations of what the device can do.
Parent reel before and after calendaring
Paper roll testing
Customer rolls are cut from the same parent reel measured before the winder.
Roll Side Measurement
Roll side measurement correlates well with the tension inside the roll. Higher roll hardness relates to higher tension.
