Abstract
Closures for shirred tubular food casings comprise a wound end-closure plug positioned entirely inside the casing bore followed by inverted casing wall tapered into the shape of a truncated cone, said closures providing significantly stronger, more resistant means for reducing the incidence of casing blow-out during filling operations.

A method of forming an end-closure inside the bore of a shirred strand of tubular casing, which comprises deshirring the terminal pleats of one end of the strand, inverting the deshirred casing into the bore of the strand, winding the deshirred casing inside the bore into an end-closure plug, and inverting shirred casing into the bore as the plug is formed wherein the walls of the inverted casing immediately adjacent to the end of the strand are tapered and remain substantially pleated.
An apparatus for forming an end-closure inside the bore of a shirred strand of tubular casing comprising:
- a rotatable, translatable gripping means for engaging a terminal end of the casing, inverting the terminal end inside the bore of the strand and for forming an end-closure plug, and
- a shaping and doffer means having a frontal nose section and a sleeve for the gripping means extending longitudinally therethrough, the frontal nose section being tapered for at least partial entry into the bore of the shirred strand without gripping the terminal end of the casing.
An apparatus for forming an end-closure inside the bore of a shirred strand of tubular casing comprising:
- a rotatable, non-translatable gripping means for engaging a terminal end of the casing, inverting the terminal end inside the bore of the strand and for forming an end-closure plug, and
- a translatable, non-rotatable shaping and doffer means having a frontal nose section and a sleeve for the gripping means extending longitudinally therethrough, the frontal nose section being tapered for at least partial entry into the bore of the shirred strand without gripping the terminal end of the casing.
