WISE - Edge Control System
With a NIPCO™ roller system, the entire material surface can be supplied with a very homogeneous linear load distribution. The system can either be equipped with a classic width setting device, a zone control for individual line load control or a newly developed "WISE Edge Control System". The WISE functionality enables a locally influenced line force, corresponding to the fabric edges. The edge zones of the materials are always subject to special requirements, since the material can deviate slightly from the central area due to preliminary processes. This system enables our customers to drive the edge area with different linear forces than the central area. As a result, higher line loads can be applied to the material at the edges. The effective width of the WISE system is adjustable and can also be adapted to the respective material width. This unique technique allows our customers to have a better control of the line load distribution throughout the material.
Example of how to manage a NIPCO™ I WISE width 2.000 mm. and consequently its 19 pistons
Thanks to the width adjusting device is possible to set different pressures in step from 100 to 300 mm. on the edge zones, in order to prevent any defect at the edges of the fabric (see images below).
NIPCO™ I WISE with selected width 1.900 mm. Here we have 3 indipendent pressure zones, a central one with 15 pistons (red – 1.500 mm.) and two later zones with 2 pistons each (yellow and blue – 200 mm.)
NIPCO™ I WISE with selected width 1.500 mm. Here we have 3 indipendent pressure zones, a central one with 13 pistons (red – 1.300 mm.) and two later zones with 1 pistons each (yellow and blue – 100 mm.)
NIPCO™ I WISE with selected width 1.300 mm. Here we have 3 indipendent pressure zones, a central one with 9 pistons (red – 900 mm.) and two later zones with 2 pistons each (yellow and blue – 200 mm.)
The width can be selected manually by handwheel or by an operator panel through a motor with an encoder managed by a PLC.
