Title:
STEEL WIRE DEFORMATION DEVICE AND USE METHOD THEREFOR, AND CORD PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/045309
Kind Code:
A1
Abstract:
A steel wire deformation device and use method therefor, and a cord production device. The deformation device comprises a plurality of pairs of deformation unit groups, wherein each deformation unit group comprises two engaged deformation units (1-10); each pair of deformation unit groups at least comprise one deformation unit (1-10) having part of convex teeth; and a plurality of deformation units (1-10) having part of convex teeth are sequentially arranged in a circumferential direction at an interval of alpha degrees according to the convex teeth. The steel wire deformation device can cause passed steel wires to form a periodic deformation sequentially, and during subsequent twisting, the steel wires pass through a twisting point to form a flat cord having a high permeability.
