Position control method and apparatus for controlling the position of the wire discharging port of a laying head

摘要

A position control system for controlling the position of the wire discharging port of a laying head to discharge a wire in a coil fashion through its revolution, compares a position reference signal which is produced depending on the running speed of a wire at the upstream location of the laying head with a position feedback signal which is produced on the basis of an revolution of the laying head, thereby to cause the laying head to discharge the wire at a desired position of the laying head. A position setter is further provided by which the leading end of the wire is discharged at a desired position.
