Abstract (en)
Apparatus for the cold working of hot rolled steel rod comprises at least two freely rotatable pulleys (18) driven by a motor (26) for orbital revolution for imparting a substantial degree of cold working to the rod as it is fed continuously through the apparatus. The rod is twisted in one direction as it enters the pulley system and is twisted in the opposite direction as it leaves the pulley system. The apparatus operates also to descale and straighten the rod continuously and is particularly useful in the production of steel rod for welded mesh in reinforcing concrete.
