Summary:Web handling apparatus pulls web from a supported roll at a selected speed. A brake is provided for controlling the roll speed and a sensor senses changes in the tension of the web caused by changes in the pulling force of the web. The brake is controlled in accordance with the output of the tension sensor so that the web is maintained substantially under constant tension. Also, the apparatus responds to the instantaneous size of the roll by modulating the braking means so that the drag force imparted by the brake to the web is substantially independent of roll size.
