ABSTRACT:
A web forwarding device wherein a web is friction driven by a drive means associated with a web pressure backing roll and a pair of pressure arms. The amount of wrap and tension around the backing roll is controlled by a pair of free floating pivotally mounted and interconnected pressure arms which hold the web on the roll. The pressure arms are adjustably mounted to control the distance between the axis of rotation of the roll and the pivot point.
