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.
Method for combining a tubular net with a surface of a carrier casing, wherein air or an inert gas is blown into the carrier casing, characterized in that the carrier casing inflated/pressurized to have a circular diameter is pulled in the direction of the tubular net towards a pleating head having a conical constrictor and 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, the carrier casing further passing through the tubular casing, followed by pulling the carrier casing covered by the net 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 protruding bulges, and finally the net/carrier casing combination is shirred by the shirring machine.
