The invention relates to an edible tubular collagen film which has a closure at either of their ends. The closure is formed by an edible solid ring-like element which tightens the end portion of casing and seals the outlet of the same, in order to stop the filling mass upon beginning of a sausage stuffing process, whereby in such a process one can rescue the initial filled sausage for its further processing, whereafter the ring disappears. This edible closing element is characterized by being of an edible, and thermoplastic composition, which is preferably based on collagen or gelatine. The solid composition has a low melting temperature and becomes adhesive at fluid state onto the surface of a collagen film which contains a certain level of moisture. The strong cohesiveness of the material of said composition in the fluid state as well as the so narrow difference between its melting temperature and the temperature of solidification, makes that a welding of said material to be set very quickly. The closure can be made before or after the shirring of the collagen casing and the present invention provides also a process to perform such a closure by heat welding the closing element on the casing material.

The invention relates to a method for producing a shirred food casing covered by a net, and a method for combining a net with a surface of a carrier casing, said method comprising steps wherein air or an inert gas is blown into the carrier casing, the carrier casing inflated/pressurized to be round is pulled in the direction of the tubular net towards a pleating head attached to one end of the tubular net, said net being attached at the open end thereof to a clamp centralized with a shirring mandrel, the carrier casing being thus folded into the tubular net while pulling the net inside out over itself, followed by pulling the carrier casing through the pleating head to the shirring machine where the pressure of air or an inert gas blown from inside of the shirring mandrel forces the areas of the carrier casing between the meshes of the net to form bulges, and finally the net/carrier casing combination is shirred by the shirring machine. The invention is further directed to a shirred product produced with the method.
