An apparatus for shirring synthetic casings wherein there is superimposed on the customary helical shirring pattern another pattern which will change the folding or shirring pleat pattern of the casing from that of the customary continuous helix so as to increase the compressibility of the casing. In its simplest form, the part cylindrical shirring surfaces of cooperating shirring wheels are machined so as cooperatively to define a cylindrical shirring surface having a center which rotates about the axis of an associated shirring mandrel.

Convoluted shirring wheel

An improved method of severing a strand of shirred casing or the like from the following casing while the casing moves along a mandrel, comprising the steps of gripping the shirred casing at two axially separated points, extending the casing to deshirr a portion thereof, gripping the deshirred portion of the casing, and axially tensioning the deshirred portion to effect a parting therein. A cam-actuated, double clamp mechanism is also provided to practice the method.
