Straightening device for aligning a line, method for braking at least one rotatable roller in a straightening device, cable processing machine with a straightening device, and upgrade kit for a cable processing machine

A straightening device (15;

• 15a) arranged to align an electrical or optical line (11) drawable therethrough by an external line drawing device (90) along a delivery route (16) in a repeated stop/restart manner, the straitening device comprising a straightening stand (20;
• 20a-20d) having a first (21) and a second (31) row of rollers arranged 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 of 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);
• wherein the braking device (40) is a magnetic braking device arranged to have the braking caused by the rotatable rollers (25, 35) as a function of their rotational speed caused by the line drawn through the straightening device.
