ABSTRACT:
A casing article which includes a tubular core member and a length of shirred casing disposed on the core with its inner periphery in gripping engagement about the core. A deshirring control is carried by the core and engages a rear portion of the shirred casing. The deshirring control prevents forward movement of the rear portion of shirred casing until all the shirred casing forward of the control has deshirred so that any forward movement of the trailing end of the shirred casing can be taken as a true indication of the depletion of casing from the shirred strand.
