The straightening of cables, strips and wires is performed in steps with successive stages until the final product is obtained. To rationalize the handling between the different steps the material is stocked on reels or on bobbins and takes forms which are not natural.
For every production step, it is therefore necessary to carry out the inverse process by taking the material off its support. At that moment, the straightening operation takes place. It may be divided into three steps:
The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers, sealed support roller, sealed support rollers.
The removal of the residual constraint in the material, due to the winding on the bobbin. This operation is performed by the rollers located in the central part of the straightener.
The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90? compared to the angle of the first rollers.
