ABSTRACT:
Disclosed is a process for shirring tubular casings, in particular sausage casings, in which the casing is conveyed in the direction of its longitudinal axis and shirred against a counterforce by means of a shirring tool. The shirred tubing portion is divided into individual shirred sticks of a predetermined length and, if appropriate, the cut-off shirred sticks are further compressed. While being shirred and in the shirred state the casing is internally supported. For cutting-off a shirred tubing portion, the transport of the casing in the direction of its longitudinal axis is momentarily interrupted, the internal support is withdrawn from the severing region, and the unshirred or deshirred tubing section is severed at the rear aperture of the shirring tool. During severing, the not-yet-shirred casing surrounded by the shirring tool is permanently internally supported. The apparatus for performing the process comprises a shirring mandrel composed of two mandrel members disposed within the tubular casing which, during the transport of the casing, are brought into flush contact. The second mandrel member, seen in the direction of shirring, may be exchanged for at least one further mandrel member.
