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, 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 when 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 being 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 chain stitches, and the tear-open thread is bound into the chain stitches.

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 sausage includes an associated sausage casing and 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.

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

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

11. The sausage casing as claimed in claim 10, 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.

12. The sausage casing as claimed in claim 10, wherein the encasing netting consists of a more elongatable material in a region adjacent to the tear-open thread than outside this region.

13. The sausage casing as claimed in claim 10, wherein the knitted encasing netting comprises honeycombs having longitudinal and transverse strands, said longitudinal strands being knitted 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 said longitudinal strands than in the region of the transverse strands.

14. A sausage 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.

15. A sausage with a sausage casing closed at the ends, wherein said sausage is encased by a sausage casing as claimed in claim 10 and the ends of the tear-open thread are secured in the end closures of the sausage casing.
