Abstract

A frusto-conical body (15) of a tissue or foil impregnated with a synthetic resin carries inside a wear-resistant metal coating (20), intended for directly contacting the thread, made from a planar foil (20') cut by photoetching from a planar stainless steel sheet having a high surface hardness and shaped to a continuous, frusto-conical ring (20") by mutually joining the ends (20a-20b) of the foil. The joint is obtained by a welding strip (ZS) formed by a laser beam.
