A straightening device for straightening cables includes two rows of rollers, an adjusting device for manually adjusting a distance between the rows of rollers, a measuring device for recording the distance between the rows of rollers, and an indicator device with which deviations of the actual value of the distance between the rows of rollers, determined by the measuring device, from a nominal value is visually indicated. The indicator device has two optical error indicating elements for indicating too high and/or too low an actual value compared with the nominal value of the distance, as well as an optical correct indicating element for indicating that the actual value of the distance corresponds with the nominal value.

Drawing unit for drawing at least one long metal product (P), configured to make the at least one long metal product (P) advance along a nominal axis of feed (A) and provided with at least a first motorized roll (13) and with at least two second rolls (14) operating at the periphery of the first roll (13) and defining, with the latter, respective passage gaps (15). The at least two second rolls (14) are located one on one side and the other on the other side of the axis (N) orthogonal to the nominal axis of feed (A) that passes through the center of rotation of the first roll (13). The second rolls (14) are associated to movement members (21) to move the second rolls (14) in a parallel form with respect to each other and in a direction substantially orthogonal to said nominal axis of feed (A) in order to adjust the passage gaps (15). The passage gaps (15) have, during use, along the straight line (R) that joins the center of the first roll (13) with the center of the respective second roll (14), an amplitude (G) that is bigger in size than the nominal diameter (D) of the metal product (P).

A configuration and method for straightening a wire as the wire pays off from a bulk package. A bulk package hat is configured to be positioned over an opened bulk package containing wire bent in a helix shape. A bearing assembly is mounted inside the bulk package hat at a position where the wire exits the bulk package hat as the wire pays off from the bulk package. A wire straightening device has a plurality of rollers and only one single plane of straightening, and is configured to apply a counter bend to the wire as the wire pays off from the bulk package through the wire straightening device. The wire straightening device is operatively connected to the bearing assembly at an angle inside the bulk package hat. The bearing assembly and the single plane of straightening rotate, continually realigning with a current direction of the wire as it pays off.

An object is to provide a wire straightening device and a wire straightening method, with which it is possible to automatically set the roller spacing in accordance with the type of the wire and to further adjust the roller spacing during operation. A wire straightening device (20) includes a preset value obtaining device that obtains a preset value of roller spacing, which is predetermined for each type of wire (2); a roller spacing automatic setting device that drives an actuator (26a) so that the roller spacing becomes equal to the preset value when the type of the wire (2) is input; and a roller spacing changing device that changes the roller spacing based on an operation by the operator while retaining the preset value during operation of a wire processing device (1).
