Abstract of corresponding document: US4292102
In a process and machine for covering a tubular member, with a covering. The tubular member is applied to a median part of the strip portion, leaving at least one protruding edge, the tubular member thus partially applied and adhering to the strip portion is engaged on a mandrel, the strip portion is wound round the tubular member engaged on the mandrel, and to effect this winding, the lateral parts of the strip portion are pulled up on each side of the tubular member, making them adhere to the portions projecting beyond the tubular member, and folding actions are carried out on the projecting parts of the raised lateral parts in order to bring them up to and attach them to the tubular member engaged on the mandrel, with a slight overlap, and the projecting portion of the strip portion is folded over opposite an open end of the tubular member engaged on the mandrel, and this projecting portion is inserted in the open end of the tubular member engaged on the mandrel, by exerting an axial action on the said projecting portion by means of a member, known as the cap, having the same section as the mandrel and mounted so as to be angularly fixed but movable by translation relative to the mandrel.
