Abstract

A wire-rolling mill having a plurality of roughing stands, a cropping shear, a finishing block, a loop layer with a laying pipe and having a drive comprising a loop-layer motor and a loop-layer gearbox and having a discharge conveyor for the finished rolled wire laid out in loops, these parts of the installation being arranged in series in the running direction of the wire. The wire-rolling mill has a control device with a computer, the computer controlling the cropping shear in accordance with a predetermined rolling program by means of a computer cutting command. In accordance with the computer cutting command, the cropping shear cuts off a certain length from the beginning of a wire strand before it enters the finishing block. It thereby produces the head of the wire to be laid out in loops. The cropping length is matched to the position of the loop layer. The loop layer is provided with an angular position sensor, which operates with digital pulses and is connected to the control device and the annular positions of which correspond to the positions of the laying pipe. The control device combines the computer cutting command and digital pulses of a predeterminable laying-pipe position sector by means of an electronic AND circuit to form a position cutting command, the cropping shear thus responding only to the position cutting command. <IMAGE>
