摘要

Invention Patent: B "WIRE FILAMENT, PARTICULARLY FOR THE REINFORCEMENT OF RUBBER OR PLASTIC ITEMS, METHOD FOR THEIR PRODUCTION AND DEVICE FOR THE USE OF THE METHOD" D. To reinforce rubber or plastic items, particularly pneumatic rims, a wire filament is proposed which has a spiral shape and does not exhibit residual elastic torsional stresses. A wire filament 8 according to the invention is produced by twisting drawn and straight wire filaments 2 in the region of plastic deformation with a subsequent counter-winding, at least two wire filaments being joined and combined before the counter-winding. Preferably at least two filaments of wire 2 are joined by means of a perforated disc 30, wound around each other and plastically deformed in a false winder 20 and subsequently counter-wound in an additional false winder 40.
