Claims (1)

[Claims for Utility Model Registration] (1) In manufacturing an elastic ring H formed by molding a wire rod, a plurality of loops L inscribed in the circumference of the ring H at arbitrary pitches are formed along the circumferential surface of the ring H. A loop forming mechanism 6 rotates a winding pin 11 that moves in and out at right angles to the circumferential surface, and the winding process cycle is repeated while the size of the ring H, the number of turns of the loop L, etc. can be freely adjusted. A wire characterized in that a servo motor 16 for forming a required elastic ring H is attached to a CNC-controlled wire rod feeding mechanism 8, a wire gripping and guiding mechanism 9 and a cutting mechanism 10 that are linked to the feeding control. homing machine. (2) A winding spindle 25 is provided which rotates forward and backward in conjunction with the forward and backward drives to appear and retract from the circumferential surface of the loop L, and rotates the winding pin 11 provided at the tip of the winding spindle 25 to move the loop L. The wire homing machine according to claim 1, which is a registered utility model, is provided with a loop L forming mechanism 6 having a configuration of forming a loop L and then reversing and retracting the loop L.
