Abstract

The apparatus for infeeding a cable in a predetermined infeed direction to an automatic cable processing machine enables moving standard cables and cables of reduced wall thickness at high velocities between the drive surfaces of two revolvingly contacting or confronting drive belts of two belt drives. By separating a drive roller synchronously driven with respect to the two belt drives from the measurement drive roller of a cable length measurement device it is possible to vary the diameter and thus the peripheral velocity of such drive roller. Consequently, there can be continuously applied to the cable a tension between the belt drives and the drive roller in accordance with the direction of movement of the cable. This cable tension prevents dam-up of the cable at this region of the cable infeeding apparatus, precludes any possible lateral departure of the cable from the belt drives and affords an exact length measurement of cable sections of the cable.
