Method of producing self-fastening systems with hooking mushrooms and loops, having a very long life, and self-fastening systems obtained by the method

摘要

The present invention concerns a male element of mushroom shape for a self-fastening closure, particularly of the hook and loop type, comprising a cylindrical rod (2) having a longitudinal axis and a cross-section, a flange (5) projecting laterally from the rod (2) and extending substantially all around the rod, characterised in that the rod has a constant cross-section or one that decreases strictly from the bottom of the rod to its apex, and there is formed in the rod an auxiliary cavity (6) of which the largest section transversely of the rod axis is of a smaller dimension than that of the cross-section of the rod (2).
