(57) The invention prevents a slack of a wire rod in a spool by preventing the wire rod
fed by rotation of the spool from returning to the spool.
A wire rod slack preventing device (20) is installed parallel to a wire rod feeding
machine (10) feeding a wire rod (11) by rotating a spool (12), around which the wire
rod (11) is wound, and has a reverse rotation roller (26) having a rotating axis which
is parallel to a rotating axis of the spool and rotating in a reverse direction to
a rotating direction of the spool while being in contact with the spool, a forward
rotation roller (27) having a rotating axis which is parallel to the rotating axis
of the reverse rotation roller (26) and rotating in the same direction as the spool
while being in contact with the reverse rotation roller (26), and a pinching roller
(28) having a rotating axis which is parallel to the rotating axis of the forward
rotation roller (27) and pinching the wire rod, which is fed out of the spool, together
with the forward rotation roller (27). Further, a wire rod slack preventing method
draws the wire rod which is fed out due to the rotation of the spool, while pinching
the wire rod by the forward rotation roller (27), which rotates with the rotation
of the spool, together with the pinching roller (28).
