An apparatus 17 for continuously forming rings of thermoplastic, shrinkable tubular casings 1 includes an unwinding roller 20, a first pair of pinch rolls 2, a ring-forming tool 3, a second pair of pinch rolls 15 and a winding-up roller 21. The tubular casing 1 is passed from the unwinding roller 20 through the pair of pinch rolls 2 and runs along a running-zone A into the ring-forming tool 3, which includes a spiral 19 and guide rollers 7 and 8 on an outer side 5 and an inner side 6, respectively, of the tubular casing 1 as well as a heater 4 for generating hot air. After covering a running-out zone B, the ring casing 16 leaving the ring-forming tool 3 runs through the second pair of pinch rolls 15, which pinches off the gas blown in at low gauge pressure in the section of the tubular casing 1, or of the ring casing 16, between the first pair of rolls 2 and second pair of rolls 15, with the result that said gas remains only in the section mentioned. The ring casing 16 is laid flat along its center line of the ring by the second pair of pinch rolls 15 and is wound up in this state onto the winding-up roller 21, in order then to be shirred and filled in a further step of the process.

Process and apparatus for continuously forming rings of thermoplastic,

A folded casing arrangement capable of being used for individually filled products is provided. The casing arrangement comprises: a casing having an extended length, the casing being arranged to have at least three portions: 1) a first end portion formed at one end of the casing which forms a stick configuration, the first end portion having a plurality of folds compressed into one another; 2) a middle portion; and 3) a second end portion including a folded portion that is folded transversely to the length of the casing. The folded portion is pleated in a longitudinal direction with respect to the casing, and the second end portion is provided with a tying means.

Folded casing for products to be filled individually

A multifunctional container capable of being used for packaging, transporting and/or soaking folded casings, said containing comprising two transverse walls, at least one of which is provided with an outlet and an outlet cover; two longitudinal side walls; a bottom connected to said longitudinal side walls and said transverse side walls, said transverse walls, longitudinal walls and bottom forming an open cavity therewithin; corner posts located at juncture positions of said transverse and said longitudinal side walls; at least two middle posts positioned vertically on said longitudinal side walls; at least one longitudinal brace which joins said two of said corner posts at a lower portion thereof; and a removable cover which is provided with an inlet and an inlet closure.
