Einzeln angetriebener Drahtziehblock fuer Drahtzuege mit Magazinbildung

摘要

There is provided an arrangement for automatically maintaining the amount of wire stored on individually driven drawing blocks in wire drawing machines at a constant level within preselected operating conditions, the arrangement comprising a friction arm and friction elements adapted to urge at a preselected pressure a wire guiding roller or like member against the wire as it is unwound from the block, and wherein means are provided for connecting the friction arm to a device which registers deviations in the angular position of the arm and transmits a signal in response to said deviations to the motor driving the block, thereby to change the speed at which the motor and/or the block rotates.
