Abstract

The invention relates to a method and device for the deformation by hydrodynamic drawing of multi-layer composite wire (8) by means of lubricant-supplied multiple drawing machines. According to said method, before the multiple drawing machine is started or restarted, directly in front of the drawing die (4) of each drawing stage a hydrostatic starting pressure acting on the drawing and other lubricant supplied thereto and on the multi-layer composite wire (6) is generated in the drawing slot by means of a heated pressure chamber (10) through which the multi-layer composite wire extends. In this way especially multi-layer composite wires (6) with a high-strength core and a soft sheath can be deformed in a high-quality manner, and during ongoing continuous drawing in a known manner hydrodynamic pressure conditions continue to be generated in the drawing slot by the entrainment of lubricant.
