Shirred wrapping tube.

摘要

The cylindrical hollow bar (1) with an inner bore which is circular in cross-section and which ends at the two end faces of the hollow bar in hollow openings (3, 4) consists of a shirred wrapping tube in combination with a covering (5) surrounding the hollow bar, leaving open the hollow openings, and of an annular body (6) at one of the two hollow openings. The annular body consists of an annular disc which bears directly with its inner side face against the adjacent end face of the hollow bar. The outer side face of the disc is at least partially surrounded by the covering. The inner bore of the disc remains free of the covering and has elements for fastening the disc onto a cylindrical filling pipe.
