Abstract

A method of an apparatus for joining plastic fastener strip continuously to a film. The film of substantial width is run continuously longitudinally through a joining station. A selected longitudinal area of the film is maintained in a stable tensioned condition relative to the remainder of the film as it runs through the joining station. In the joining station, there is joined and secured to the tensioned area a fastener strip running in the same direction and at the same speed as the film. The selected area tensioning is effected by maintaining such area offset relative to the remainder of the film. Downstream from the joining station the film and fastener strip assembly is progressively conditioned until thoroughly stabilized.
