Abstract
PURPOSE: To hold the exit of a wire rod guide and a wire rod contacting part at a set distance by providing a sensor, which generates a signal when coming into contact with a coil spring tip, on the front surface moving direction of the coil spring and by exercising control with the signal when the extent of the feed of a wire rod in the generation of the signal is specified.
CONSTITUTION: In front of a coil spring coiled with tools 8 and 9 in its moving direction, sensor 16 is provided which generates a signal when touching the leading end of the coil spring, when not touching the leading end as wire rod 1 constituting the coil spring is fed out to a specific extent, or when touching the leading edge before wire rod 1 is fed out to the specific extent. According to the extent of the feed of wire rod 1 in the generation of the signal or the signal when it is specified, either or both of tools 8 and 9, and wire rod guide 4 are moved to hold the exit of wire rod guide 4 and the wire rod containg part of tools 8 and 9 at a set distance.
