ABSTRACT:
Apparatus and method are provided for producing a compressed, rolled package of resilient foam material, wrapped with a flexible sheet material which is divided into a plurality of sections separated by pre-weakened areas along its length. The flexible sheet material is advanced by an upstream set of clutch-brake nip rolls and a downstream set of drive nip rolls. The two sets of nip rolls are operated in such a manner as to separate a single wrapping sheet from the length of flexible sheet material and to advance the single sheet into contact with the foam piece for feeding to a rolling and compressing packaging apparatus.
