Abstract

Solid or hollow smooth or ribbed coiled bars are straightened by guiding the bar through grooved rolls whilst being drawn through a pre-straightener assembly, and two straightener assemblies to a finishing assembly, the bar passing through at least one S shaped or Z shaped half loop during straightening whilst remaining generally on a single plane until the finishing assembly. Appts. comprises an antirotation machine for operation on a single plane and having a guide and prestraightener assembly, two-straightening assemblies with at least two drawing units, a linear forming assembly and a finishing assembly.
