Mass flow control system for wire drawing machine

A wire drawing machine having a die and rotating block wherein wire is drawn through said die by said rotating block, said block being driven by a variable speed motor, the thus drawn wire being accumulated as a plurality of windings on the block before being removed therefrom via a guide, the guide being arranged on a carrier which rotates independently of the block about the axis of block rotation when a difference exists between the rates at which wire is wound onto and removed from the block, the improvement comprising:

• a control system including motion detection means arranged to coact with the carrier in generating electrical signals representative of the direction and speed of rotation of said carrier, and control means associated with said motor and said motion detection means and responsive to said signals for adjusting the rotational speed of said block in order to reach a steady state condition where wire is being wound onto and removed from said block at the same rate, and said carrier remains motionless.
