Abstract

The tensioning of elongated tubular workpieces during transport through a multi-pass cold-drawing apparatus is regulated by changing the speed of discrete electric motors which drive work advancing drums located downstream of successive reducing dies. The speed of the motors is regulated in response to electric signals which are produced by first pressure gauges serving to measure the peripheral forces of the drums and second pressure gauges which measure the retarding forces of the preceding reducing dies. The evaluating circuit employs discrete first and second amplifiers which are respectively connected with the first and second pressure gauges, differential amplifiers each of which receives signals from a first and a second amplifier, rated value selecting devices which furnish preselected signals of constant intensity, and signal comparing circuits which compare the preselected signals with signals furnished by the corresponding differential amplifiers and produce motor-adjusting signals.
