ABSTRACT:
The present invention relates to a method of regulating the drive of a multiple drawing machine or drawing device, respectively, as well as to a device for drawing billets. By means of the method it is possible to drive a wet drawing machine such that slip-free operation is also achieved. The device according to the invention comprises a drive regulation suited for slip-free wet operation. By means of the present invention, substantial improvements of the quality of the drawn product, in particular of wires of copper, copper alloys or special materials, respectively, are achieved. The operation substantially is performed automatically, and an automatic adaptation of the device to modified operating conditions, such as modification of the property of the material of the billet, is effected.
