Method and system for preventing torsion wire, prismatic material and cross section rod.

摘要

A bending machine, comprising a feed unit (2) for advancing wire rod, or material prismatic cross section, (1) to a bending unit (3), characterized by: a jaw (4) mounted on a carrier (5) so that it can move in parallel with wire or rod material prismatic cross section (1) advancing between the feed unit (2) and the bender (3); said jaw (4) is activated by compressed air, or hydraulically or electromechanically, in order to capture the advancing material (1) so that the advancing material (1) carries the jaw (4) and advances the jaw (4) together with the carrier (5) towards the bending unit (3); and, some cylinder, or motor, or mechanical force of return such as a spring force or the force of gravity performs the return of jaw (4) towards the feed unit (2).
