ABSTRACT OF THE DISCLOSURE Disclosed is a supporting sheath for a longi- tudinally shirred packaging tube, comprising a generally tubular shaped supporting sheath comprised of a grid-like structure and having an inside diameter slightly larger than the outside diameter of the shirred packaging tube and a length substantially greater than the length of the shirred packaging tube, so that when a shirred pack- aging tube is placed inside of the supporting sheath, two protruding ends of the supporting sheath remain; and a pair of generally planar star-like disc elements, each including a central aperture therein and a plurality of point-like projections spaced around its outer circum- ference, each of the disc elements having an outer dia- meter defined by the ends of the point-like protrusions which is larger than the inside diameter of the sup- porting sheath; wherein the star-like disc elements are adapted to be slid over the protruding ends of the supporting sheath and are adapted to engage with their point-like protrusions the grid-openings of the sup- porting sheath when the sheath ends are folded back 180° upon themselves. Also disclosed are a functional unit comprised of the shirred packaging tube and the sup- porting sheath as well as a method for producing the functional unit.
