Abstract

An apparatus for the continuous production of individual flexible products from a folded web of material, in particular, heat sealable thermoplastic material, is described having improved means for providing tension relief in such web material, and for tucking such web material outwardly from the surface of the product drum. The tuck rolls remain extended above the surface of the product drum throughout product drum rotation, and are retracted by cam arrangement to provide tension relief. Three alternative support assemblies and related cam arrangements are disclosed, two of which employ adjustable, compressible tuck roll support assemblies.
