Vishay to install Rider Roll System in Canadian Paper Mill

July 25, 2008 — Vishay Intertechnology received an order from NewPage Corporation to install a customized Rider Roll System in its mill in Port Hawkesbury, Nova Scotia, Canada. NewPage Corporation is a leading North American producer of printing paper. Its Port Hawkesbury Mill produces supercalender and high bright newsprint paper. Vishay's customized Rider Roll System, to be delivered in the fall of 2008 to the Port Hawkesbury Mill, will use strain gage-based load cells to control the winding process of finished rolls. The system will precisely control nip force by direct measurement of forces on both sides of the machine.

Vishay's Rider Roll System for winders is a force and position control system with separate controls for each side. The system is designed to maintain precise yet variable web tension in the winder as the roll diameter increases. The system also features soft "core" contact with high nip-load accuracy and dynamic force detection to prevent roll "kickouts." The Vishay system will replace an existing pressure feedback control system, which could not accommodate for machine wear. By direct measurement of nip forces through strain gage-based load cells, the Vishay Rider Roll System can compensate for friction and machine wear, thus revitalizing older machines.

Vishay’s Rider Roll System will be installed on Port Hawkesbury’s paper machine number 1 winder, which produces newsprint. The winder machine, installed in 1971, has a trim width of 8.4m and a maximum speed of 2,200m/min.
