Patent

CA 2080724

Abstract of the Disclosure An apparatus and method is provided for processing and rewinding a web made of easily stretchably deformable plastic film. The web is drawn from a supply roll assembly by a series of synchronously, positively driven draw and transfer rolls and directly delivered to a rewind spindle. The rewind spindle is positively driven at a speed greater than the speed imparted to the web by the draw and transfer rolls. However, the rewind spindle is in peripheral contact with a transfer drum which is the last of the series of draw and transfer rolls so that the processed web is immediately transferred from the transfer drum to the rewind spindle. The transfer drum exerts a drag on the rewind spindle to control and match the speed of the rewind spindle to the speed of the moving web.
