Steel reinforcement rod and process for producing this rod.

摘要

A process for producing steel reinforcement rod for concrete by cold working comprises feeding an indefinite length of the rod through a cold working station at which the rod is twisted in one direction about its axis and is then untwisted. The invention extends to the product of this process. The rod enters the twisting station as it leaves pulley 22 and leaves the twisting station via pulley 34. The rod also passes round pulleys 18 which are mounted on a rotatable carriage 16 so that twist is imparted between pulleys 22 and 18 and untwisting occurs between pulleys 18 and 34.
