Abstract
A process for providing feedforward control to control the feed rate of an elastic material. The process involves measuring the distance between registration marks on the elastic material prior to cut-off. These measurements are compared to a target cut length. The feed rate of a feed roll is adjusted, based on the target cut length and the distance between the registration marks, to maintain the cut length of the elastic material at the target cut length.
