ABSTRACT:
An end closure for a shirred casing stick is formed from casing inturned into the bore of the stick. A vacuum assist is used to prepleat the casing within the bore prior to compaction. The resulting end closure is a generally cylindrical plug composed of accordion-type pleats and having an end portion which has a substantially uniform density about the longitudinal axis of the plug and a second portion which has an asymmetrical density. The second portion has two longitudinally extending sections; one having its pleats formed of a single ply of casing and a diametrically opposite section having its pleats formed of three plies of casing, thereby providing the asymmetric density.
