Apparatus for maintaining the relative position between wire being fed onto and wire wound about a spool

摘要

Apparatus for winding wire on a spool comprises guide means (37) for guiding the wire onto the spool; a sensing arm (21) movably responsive to sideways shifting of the wire during winding and displacing means for displacing the guide means dependent upon sensing arm movement. The displacing means comprises a rotary hydraulic servo-valve (15) connected by a shaft (2) to the sensing arm, and a hydraulic cylinder (17) connected to the servo-valve and shiftably movable relative to the spool. As the angle between the wire being fed onto the spool and the wire wound about the spool changes, the sensing arm is displaced thereby actuating said hydraulic cylinder and causing movement of said guide means thereby reestablishing the relative position between the wire being fed onto the spool and wire wound about the spool.
