A web-handiing apparatus includes at least one guide roller assembly having an inner, cylindrical core, and an outer layer affixed thereto. Notably, the outer layer of the roller assembly comprises resiliently deformable material, with polyurethane foam having proven to be particularly suitable for this application. By this arrangement irregularities in an associated film web, such as in the form of side gussets and/or zipper fastener assemblies, are readily guided by the roller assembly while avoiding wrinkling or other stress of the associated film web. |
