Abstract
A process of forming an end closure of one end of a stick of shirred sausage casing. The casing 10 is twisted and then the twisted neck (16) is compressed and heated to seal it. The twisted portion is severed so as to form an end seal with about four to eight twists in it. This end seal resists rupture during stuffing.
