Abstract:
A control system is provided for a converting line. The converting line has an unwinder for unwinding web material from a roll of web material and at least one independently driven roll for directing the web material unwound from the unwinder to the converting line. The control system has a controller and a tension sensor configured to be arranged downstream of the at least one driven roll. The tension sensor is configured to sense a tension in the web as the web is passed downstream of the driven roll, generate a signal indicative of sensed web tension, and transmit the signal of sensed web tension to the controller. The controller is configured to a generate and transmit to the unwinder a signal to change the speed of the unwinder based upon the tension sensed by the tension sensor.
