Abstract:

PCT No. PCT/EP96/03885 Sec. 371 Date May 15, 1998 Sec. 102(e) Date May 15, 1998 PCT Filed Sep. 4, 1996 PCT Pub. No. WO97/12092 PCT Pub. Date Apr. 3, 1997For reinforcing rubber or plastics articles, particularly pneumatic tires, a wire filament is proposed which is spirally shaped and exhibits no elastic residual torsional stresses. A wire filament 8 according to the invention is produced by twisting drawn straight wire filaments 2 into the range of plastic deformation with subsequent return-twisting, at least two wire filaments being brought together and combined prior to return-twisting. Preferably at least two wire filaments 2 are brought together by means of a perforated disk 30, twisted about each other and plastically deformed in a false twister 20 and subsequently return-twisted in a further false twister 40.
