ABSTRACT:
The packing of a tubular casing segment which has been shired together into a hollow cylindrical shirring formation occurs in a tubular net of such configuration that first, with the shirring accomplished with the aid of an abutment which is movable on the shirring tube, a certain initial segment of the tubular casing length is allowed to be left unshirred. Following termination of the shirring, the shirring tube is withdrawn with the abutment from the tubular shirring formation, and the unshirred tubular casing length segment is narrowed down or swaged and is sealed. Finally the sealed tubular casing length tip is inserted with force into the shirring and together with the shirring is thrust through a cylindrical carrier, in which a tubular net is recovered which is sealed to the tubular shirring. This is turned inside out with the thrusting through of the tubular shirring and surrounds this part along its entire length. Finally the tubular net with the tubular shirring incorporated therein is sealed at the other end at two points one after the other in sequence and is separated between said two points. With the further processing of the shirred formation this formation need only be irrigated and the opposite end of the packing need only be torn away, in order to be able to place the shirred formation on the stuffing horn and to be able to begin the filling immediately.
