A device for controlling web tension is disclosed. The device includes a carriage in which a first guide roller is spaced from a second guide roller by a frame. The carriage or frame pivots about a pivot location. A moving web is threaded through the carriage in a serpentine path. Rotation of the carriage or frame causes web displacement. When tension disturbances occur in the moving web, the device rotates for accumulating or releasing the web material and thereby dampening tension variations downstream. The pivot dancer device can be placed in a communication with a controller for open loop control or closed loop feedback control.

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.
