A straightening device (15;

• 15a) arranged to align an electrical or optical line (11) drawn therethrough, the straightening device comprising an external line drawing device (90) configured to draw the electrical or optical line along a delivery route (16) through a straightening stand in a repeated stop/restart fashion manner, the straightening stand (20;
• 20a-20d), has two rows of rollers (21, 31) which are movable relative to each other and between which the delivery route of the electrical or optical line passes, wherein at least one of the two rows of rollers (21, 31) has a plurality rotatable rollers (25, 35), the straightening device further comprising a braking apparatus (40) for braking at least one of the plurality of rotatable rollers (25, 35) from the at least one of the two rows of rollers (21, 31) in the straightening stand (20;
• 20a-20d), and a control device having a processor which processes control commands and transmits the control commands to the external line drawing device, the braking apparatus, and to drive devices of the straightening stand according to a predefined step sequence.
