METHOD FOR PRODUCING A NETTED CASING

摘要

The invention relates to a method for producing a shirred food casing covered by a tubular net and to a method for applying a net to the surface of a carrier casing. This method comprises steps wherein air or an inert gas is blown into the carrier casing, the carrier casing inflated/pressurised to become round is pulled in the direction of the net towards a pleating head attached to one end of the net, which is attached, at the open end thereof, to a clamp centralised with a shirring mandrel. Thus, the carrier casing is folded into the tubular net while pulling the net inside out over itself, whereafter the carrier casing is pulled 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. Finally, the net/carrier casing combination is shirred by the shirring machine.
