CA 2071184

Severing a shirred stick of sausage casing from casing feed stock joined to the stick is accomplished by perforating a section of the casing across its flat width prior to moving the section through a shirring zone. The section is then moved to a shirring zone where longitudinal movement of the casing is restrained to put the casing in tension across the line of perforations. The resulting tension tears the casing apart along the line of perforations. In one embodiment the shirring rolls are operable to incorporate a torn end of the casing into the shirred stick by gathering the torn end up into a pleat at the last-shirred end of the stick.
