Abstract: A folded casing, shirred to form a stick, is packaged in a packaging net (10). The two net ends (12, 13) which are opposite to one another are welded ultrasonically. A strip (14), consisting of the same material as the packaging net 10, is also welded ultrasonically to at least one of the new ends 12 or 13.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a cylindrically-shaped hollow rod which is closed at one end, comprising a shirred tubular casing, and an integral, essentially cylindrically-shaped, plug-type closure element which is coaxially arranged in the cavity of the hollow rod and which comprises a deshirred tubing portion and an irregularly folded, compressed tubing portion, wherein a first one of the tubing portions is adjacent to the inside wall of the hollow rod, and the second tubing portion is surrounded by the first tubing portion, wherein one end of the first tubing portion, which points in the direction of the open end of the hollow rod, is bent back at an angle of 180.degree. and integrally changes into the second portion, and wherein the other end of the first tubing portion integrally changes into the hollow rod. Also disclosed is a process for producing the hollow rod having the end closure according to the invention.

Abstract: Disclosed is a process for shirring tubular casings, in particular sausage casings, in which the casing is conveyed in the direction of its longitudinal axis and shirred against a counterforce by means of a shirring tool. The shirred tubing portion is divided into individual shirred sticks of a predetermined length and, if appropriate, the cut-off shirred sticks are further compressed. While being shirred and in the shirred state the casing is internally supported. For cutting-off a shirred tubing portion, the transport of the casing in the direction of its longitudinal axis is momentarily interrupted, the internal support is withdrawn from the severing region, and the unshirred or deshirred tubing section is severed at the rear aperture of the shirring tool. During severing, the not-yet-shirred casing surrounded by the shirring tool is permanently internally supported.
