WIRE FILAMENT, PARTICULARLY FOR REINFORCING RUBBER OR PLASTICS ARTICLES, METHOD OF PRODUCTION THEREOF AND DEVICE FOR IMPLEMENTING THE METHOD |
摘要 |
<p>The proposal is for a wire filament for reinforcing rubber or plastic items, especially pneumatic tyres, which is spiral in shape and exhibits no residual elastic torsional stresses. A wire filament (8) of the invention is produced by twisting drawn straight wire filaments (2) in the plastic deformation region followed by reversal, two wire filaments being put together and secured at the latest before reversal. Advantageously, at least two wire filaments (2) are brought together by means of a perforated plate (30), twisted around each other in a false twister (20) and plastically deformed and then reversed in a further false twister (40).</p> |
