APPARATUS FOR CONTROLLING WIRE WINDING ONTO ROTATING BOBBIN Russian patent published in 2006 - IPC B21C47/02 

FIELD: wire production systems, possibly for drawing benches, flow-through furnaces and so on.

SUBSTANCE: apparatus includes drive unit for moving bobbin along its axis and in addition it is provided with unit for servo-control of predetermined angle of winding. Drive unit is in the form of hydraulic cylinder; servo-control unit includes slide valve with probe in one end. Slide valve is mounted in hydraulic supply system of hydraulic cylinder with possibility of spring-loaded contact of probe with wound wire branch. Slide valve is mounted in such a way that it periodically shifts from its mean position due to fluctuation of winding angle relative to preset angle value. It may be automatically returned to mean position when said angle becomes equal to target value.

EFFECT: possibility for controlling winding of wire regardless its diameter, shortened time period of adjustment of winding apparatus.
