Abstract

With a device for controlling the drive of a reel, with a wire supply in the form of a coil of said wire supply, from which the wire, through interposition of a tensioning device, which is spring-pretensioned in one deflection direction and effective up to a maximum deflection, for approximated stabilization of the wire tension of a feed installation of the wire infeed of a downstream positioned wire processing machine, the velocity curve of the feed rate of the wire infeed in accordance with a preset velocity-time profile is controlled by a control unit of the wire processing machine, and whereby the curve of the rotation speed of the reel in accordance with a preset rotation speed-time profile is controlled by the drive control of the reel, whereby the drive control of the reel sets the rotation speed-time profile of the reel, with regard to the velocity-time profile of the feed rate, forward by a preset time interval.
