Abstract

The invention relates to a process for wire patenting in which, after passing through a lead bath (1), the wire (3) is drawn on a flat, rising path controlled by guides (2, 4, 9) through a bed (7) of loose abrasive material, preferably coke grit and the wire path inside the granulated bed is changed at intervals or continuously. In wire patenting, the lead bath (1) serves to drop the wire temperature very rapidly and within narrow tolerances from about 1000 to about 500 DEG C, thus giving a microstructure easily drawn. In order to ensure the continuous cleansing of lead from the wire with the part of the process of wire patenting relating to the partial regeneration of the coke grit stripping bed (7), it is proposed according to the invention that the wire path within the granulated bed be determined by three guide members, with the outer two (2, 4) fixed and the centre one (9) movable.
