摘要:
A prepackaged shirred tubular casing article comprising a shirred casing length having a sizing means confined within an unshirred portion of said casing length, said sizing means having an outer perimeter larger than the inner perimeter of said unshirred casing length.

A shirred stick of flexible tubing having a straight bore and an ordered pattern of shirred pleats has an improved coherency and is provided with one or more longitudinal grooves formed and extending on its outer surface from one end of the stick to the other. The grooves are formed by passing the shirred tubing through a restraining device comprising one or more blades disposed about a shirring mandrel to engage and longitudinally indent the outer surface of the shirred tubing.

A natural casing is shirred onto a self-supporting tubular carrier member. The carrier member is formed of an extruded plastic material, such as polyethylene, which has an inherent elastic memory, and which is severed along a portion of its length prior to the placement of the casing thereon. The line of severance terminates short of one end of the tubular member to provide a closed circumferentially continuous end portion. The elastic memory of the material causes the wall portion adjacent one side of the line of severance to curl beneath the wall portion at the other side for the line of severance, so that the carrier member assumes a generally frusto-conical configuration. The inner diameter of the casing is larger than the small diameter portion of the carrier member so that the casing can be readily shirred thereon, although the inner diameter of the casing is smaller than the larger diameter portion of the carrier member to prevent axial displacement therefrom. a holding member is provided at the small diameter end of the carrier member to positively retain the casing in place.

Shirred casing is packaged in pockets on a belt to assist in the stuffing of the shirred casing by an automated stuffing machine. The package is made up of a belt with pockets for the shirred casings. The pockets provide structural integrity to the shirred casings and are spaced evenly for automated handling. The automated stuffing machine has a strand drum with indentations to receive the pocket of the package. The strand drum acts as an indexing mechanism to position each successive pocket so that the shirred casings within may be stuffed. A stuffing horn moves between a stuffing position and an indexing position that is clear of the strand drum. A method for automating the stuffing of shirred casings is disclosed as well.

A holder for retaining shirred gut sausage casing comprising an elongated, flexible, self-supporting, flattened tube having a longitudinal uninterrupted slit. The flattened tube comprises a pair of opposed parallel walls terminating in longitudinal edges at the slit. The flattened tube is formed from a relatively firm, flexible sheet material having a low coefficient of friction.

A shirred casing article is composed of a cut length of fibrous casing and must be soaked prior to stuffing. A loop is attached at one end of the cut length for hanging the casing after stuffing. However prior to stuffing, the loop is extended longitudinally about the shirred casing article to maintain the integrity of the shirred casing during soaking. Thus the loop which functions as a means to suspend the casing after stuffing, functions before stuffing as a means to restrain longitudinal expansion of the shirred article.

The bundling together of shirred food casing sticks is accomplished by loosely supporting the sticks in a desired stack configuration, drawing a stretch film from below the stack, folding the film over the top of the stack and taping the film to itself, and then pulling the film downwardly to tighten it about the stack and heat sealing across the bottom of the stack.

The invention is a package including a bundle of shirred casing sticks disposed and held together by a container which completely encloses the bundle. The container is formed insitu about the bundle from a heat shrink film which stiffens on heat shrinking to provide a self-supporting container conforming in shape generally to the bundle shape. During heat shrinking, portions of the film are insulated to prevent welding of these portions so they provide flaps which open to permit removal or replacement of sticks.

The shirred casing disclosed is packaged in a plastic tube with the lead end of that tube formed into a combined brake/size means which applies oblique frictional force and variable size control to the food emulsion as it is being extruded into the case; also disclosed are means for permitting gas pressure build-up to be relieved and the gas to escape.
