Abstract
A tube, in particular sausage casing, is composed of mutually connected sections which at the connection point, prior to connection, possess cut edges extending approximately at right angles to the longitudinal axis of the tube and parallel to each other. The sections are connected by an adhesive tape extending around the outside of the tube. When the tube, possessing two folded edges extending parallel to each other, is flattened, the part of the cut edges of one section extending from a first folded edge of the other opposite folded edge is situated within the tube and the other part of this cut edge, which extends from the second folded edge back to the first folded edge, is situated on the outside of the tube. Parts of the cut edge of the other section are situated in reversed arrangement, firstly on the outside of the tube and then within the tube.
