Abstract

A tubular encasing netting for sausage and similar articles. The encasing netting contains a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting in the state of use of the latter. This results in loops of the tear-open thread which are accessible from outside and which can be grasped for tearing open. The encasing netting is expediently a double-rib or warp-knit fabric. The tear-open thread is received in stitches of this fabric. The invention relates, furthermore, to a method for producing such an encasing netting, to a sausage casing connected to the encasing netting and to an article encased by this encasing netting.

Claims

1. A tubular encasing netting for sausage and the like, which has a structure which is extendible in the longitudinal direction, wherein said encasing netting has a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting which is in the state of use and forms at least one loop capable of being grasped on the outside of the encasing netting, the ends of the loop are connected to points of the encasing netting which are at a greater distance from one another in the longitudinally extended state of the encasing netting than in its state of use.

2. The netting as claimed in claim 1, wherein the encasing netting comprises honeycomb strands which are composed of knitting stitches, and the tear-open thread is bound into these.

3. The netting as claimed in claim 2, wherein the honeycomb strands of the encasing netting are knitted partially as fringes, and the tear-open thread is bound into the fringes.

4. The netting as claimed in claim 3, wherein the tear-open thread lies between a pair of stitch legs and a sinker thread.

5. The netting as claimed in claim 4, wherein the sinker thread lies on the outside of the encasing netting.

6. The netting as claimed in claim 2, wherein the encasing netting strands containing the tear-open thread are adhesively bonded to the associated sausage casing and/or to the tear-open thread.

7. The encasing netting as claimed in claim 6, wherein the encasing netting is not adhesively bonded to the sausage casing in the vicinity of the tear-open thread.

8. The encasing netting as claimed in claim 6, which comprises a more elongatable material in a region adjacent to the tear-open thread than outside this region.

18. A sausage casing which is connected to an encasing netting as claimed in claim 1.

19. The sausage casing as claimed in claim 18, wherein the encasing netting is adhesively bonded to the sausage casing.

20. The sausage casing as claimed in claim 19, wherein, in a region adjacent to the tear-open thread, the encasing netting is not adhesively bonded or is adhesively bonded to a lesser extent to the sausage casing than outside this region.

21. The sausage casing as claimed in claim 19, wherein the encasing netting consists of a more elongatable material in a region adjacent to the tear-open thread than outside this region.

22. The sausage casing as claimed in claim 18, wherein the knitted encasing netting has honeycomb strands running in the longitudinal direction and designed as a tricot, and adhesive bonding to the sausage casing is more secure or more frequent or over a larger area in the region of these longitudinally running honeycomb strands than in the region of the transversely running honeycomb strands.

23. A sausage or the like with a sausage casing closed at the ends, wherein said sausage is encased by an encasing netting as claimed in claim 1 and the ends of the tear-open thread are secured in the end closures of the sausage casing.

9. A method for producing a netting tube by knitting or tying, which has a greater length in the production state than in the state of use, wherein, during production, a tear-open thread is worked in, which, during the shortening of the encasing netting at the transition to the state of use, is caused to form, between at least two points at which it is connected to the encasing netting, a loop which is accessible from outside.

10. The method as claimed in claim 9, wherein the encasing netting is produced as a double-rib or warp-knit fabric, and the tear-open thread is inserted into knitting stitches.

11. The method as claimed in claim 10, wherein the tear-open thread is inserted in each case into a stitch of all the fringes of successive netting honeycombs.

12. The method as claimed in claim 9, wherein the tear-open thread is inserted between the stitch legs and the associated sinker thread.

13. The method as claimed in claim 12, wherein the fabric is subsequently reversed, if the sinker thread lies on the inside during production.

14. The method as claimed in claim 9, wherein the encasing netting is adhesively bonded to the sausage casing.

15. The method as claimed in claim 14, wherein, in a region adjacent to the tear-open thread, the encasing netting is not adhesively bonded or is bonded to a lesser extent to the sausage casing than outside this region.

16. The method as claimed in claim 15, wherein the encasing netting and/or the sausage casing, before being connected, is impregnated in a bond-inhibiting manner in a region adjacent to the tear-open thread at least on one side.

17. The method as claimed in claim 9, wherein a more elongatable material is used for the netting within a region adjacent to the tear-open thread than outside this region.

24. A sausage or the like with a sausage casing closed at the ends, wherein said sausage is encased by a sausage casing as claimed in claim 14 and the ends of the tear-open thread are secured in the end closures of the sausage casing.
