It is. Since the three feed-in rollers 41 continues to descend, even main reinforcement conveying means 43 reciprocates, there is no lower claw unit 59 can interfere with the feed-in rollers 41.

The electric welding machine 21 lowers the upper electrode 31 and welds the auxiliary muscle C to the main muscle B. After the first auxiliary muscle C is welded to the main muscle B, the main muscle conveying means 43 moves again by the pitch P2 of the auxiliary muscle C while holding the main muscle B.
The electric welding machine 21 welds the second auxiliary muscle C to the main muscle B. In this manner, the auxiliary muscle C is sequentially welded to the main muscle B at the set pitch P2 by repeatedly moving and stopping the main muscle transporting means 43 and welding the electric welding machine 21. During this time, the tip of the main muscle B approaches the pull-out device 23.

When the leading end of the main bar B approaches the drawer 23 to some extent, it is provided on the clamp mechanism 76 of the drawer 72.
And five auxiliary muscle engagement lever 83 is tilted by the air cylinder 84 in a counterclockwise direction as shown in FIG. 10, the pawl 8
