Field of Application :
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:
1.The straightening, consisting of putting the material back into its original shape. The operation is carried out by the first straightening rollers.
2.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.
3.The forming of the wire carried out by the last rollers on the straightener, generally placed at an angle of 90compared to the angle of the first rollers.
Often it is necessary to combine these three steps. That is the reason why the straightener uses 5, 7, 9, 11 or even 13 rollers placed in two planes.The manufacturing precision of the roller has a major influence on the quality of the final product (wires) as well as on the service life of the rollers. It is therefore essential that the rectified V notch on the outer ring has the same geometric characteristics and precision as the rest of the bearing. For this reason, the notch on a NLHB roller is precise machined prior to bearing assembly.
