Abstract
A travelling web made of packaging film is folded about collated sheets of material in response to a reversal in travel direction of the web about an arrangement of three guide edge segments. Two of the guide edge segments on either side of the intermediate guide edge segment form parts of two triangular folding guide members through which the web is folded into transversely overlapping portions overlying an intermediate portion reversed in travel direction by the intermediate guide segment.
