摘要
In the process for shirring such casings of elastically and plastically deformable material, a shirring tool (6) passes along the casing (5) transported in the direction of its longitudinal axis and inflated with a support gas, and the casing (5) is laid into folds by the tool and against an opposing force is tightly compressed together in a concertina fashion. Moreover, to increase the shirring density and to increase the breaking strength of the concertina, the casing is stretched apart in the circumferential direction, preferably by 5 to 15%, prior to the shirring element. It is particularly advantageous to have the shirring element act immediately after stretching, before the elastic recovery is completed. A suitable shirring device for carrying out the process is also described, which has, on the shirring core (1) prior to the shirring tool, an expansion component (2).
