Encasing netting for sausage and method for producing it

Abstract

A tubular encasing netting ( 1 ) for sausage and similar articles. The encasing netting ( 1 ) contains a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting ( 1 ) in the state of use of the latter. This results in loops ( 7 ) of the tear-open thread which are accessible from outside and which can be grasped for tearing open. The netting is expediently a double-rib or warp-knit fabric. The tear-open thread ( 3 ) is received in stitches of this fabric. The invention relates, furthermore, to a method for producing such a netting, to a sausage casing connected to the netting and to an article encased by this netting.

1 . A tubular encasing netting for sausage and the like, 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.  
     
     
         2 . The netting as claimed in  claim 1 , wherein the tear-open thread forms at least one loop capable of being grasped on the outside of the netting.  
     
     
         3 . The netting as claimed in  claim 2 , wherein said netting has a structure extendible in the longitudinal direction, and the ends of the loop are connected to points of the netting which are at a greater distance from one another in the longitudinally extended state than in the state of use.  
     
     
         4 . The netting as claimed in  claim 1 , wherein the netting has honeycomb strands and the honeycomb strands of the netting are composed of knitting stitches, and the tear-open thread is bound into these.  
     
     
         5 . The netting as claimed in  claim 4 , wherein the honeycomb strands of the netting are knitted partially as fringes, and the tear-open thread is bound into the fringes.  
     
     
         6 . The netting as claimed in  claim 5 , wherein the tear-open thread lies between a pair of stitch legs and a sinker thread.  
     
     
         7 . The netting as claimed in  claim 6 , wherein the sinker thread lies on the outside of the netting.  
     
     
         8 . The netting as claimed in  claim 4 , wherein the netting strands containing the tear-open thread are adhesively bonded to the associated sausage casing and/or to the tear-open thread.  
     
     
         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 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 netting, a loop which is accessible from outside.  
     
     
         10 . The method as claimed in  claim 9 , wherein the 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 an 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 . A sausage casing which is connected to an encasing netting as claimed in  claim 1 .  
     
     
         15 . The sausage casing as claimed in  claim 14 , wherein the encasing netting is adhesively bonded to the sausage casing.  
     
     
         16 . The sausage casing as claimed  claim 15 , 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.  
     
     
         17 . A sausage or the like with a sausage casing closed at the ends, wherein said sausage is encased by an encasing netting  9  as claimed in  claim 1 .  
     
     
         18 . A sausage or the like with a sausage casing closed at the ends, wherein said sausage is encased by an encasing netting a sausage casing as claimed in  claim 14  and having end closures and the ends of the tear-open thread are secured in the end closures of the sausage casing.  
     
     
         19 . The netting as claimed in  claim 2 , wherein the netting has honeycomb strands and the honeycomb strands of the netting are composed of knitting stitches, and the tear-open thread is bound into these.  
     
     
         20 . The netting as claimed in  claim 3 , wherein the netting has honeycomb strands and the honeycomb strands of the netting are composed of knitting stitches, and the tear-open thread is bound into these.
