An aligning device (15) for straightening a wire (11) which comprises an aligning system (20) having a first row of rollers (21) and a second row of rollers (31) which can be moved relative to one another. The aligning device (15) comprises a measuring unit (40) for determining a wire diameter and/or a tensile force measuring mechanism (70). A method for adjusting the aligning system (20) and a method for setting the aligning system (20), as well as a wire processing machine having at least one aligning device (15) are also disclosed.

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.
