Abstract

A method and an apparatus for reducing embedded or inherent torsional strains in reinforcement steel (2) by guiding the reinforcement steel (2) between at least one set of two rows with straightening means. There are at least two straightening means in the first row and three in the second row and the means have grooves for receiving and guiding the reinforcement steel (2). One of the straightening means is displaced and locked in position for the formation of a curved path for the reinforcement steel.
