Method to twist exit wires whereby each wire is placed in moving seat thereby creating wire section and pushed along feeder, force is applied in contact zone to bend and deform wire; device to carry this out and resulting wire product

摘要

Each exit wire (Fa) has a corresponding feed section (P3a). Firstly, each individual wire is positioned in a number of seats (S7a,etc) spaced at a distance from each other and which move from back to front when working, creating a series of wire sections (F6a,etc) on the wire, which are pushed along the feed section from back to front. Secondly, during this movement a coresponding force is exerted in a contact zone (Za4) lying between two seats through which the wire sections are bent. The contact zones are adjusted so that each wire (Fa4/Fa3) undergoes one deforming near the preceding seat and a second permanent deformation in the contact zone and a third permanent deformation near the following seat.
