Electric wire delivery apparatus and electric wire sizing-cutting apparatus including the same

An electric wire delivery apparatus comprising:

• a transfer device transferring an electric wire delivered from an electric wire reel along a longitudinal direction of the electric wire, the transfer device including a pair of oppositely disposed rotary belts arranged in a transfer direction of the wire, the rotary belts receiving the electric wire therebetween so as to transfer the wire along the longitudinal direction thereof;
• a correcting device arranged between the electric wire reel and the transfer device and correcting a bending habit of the electric wire by allowing the electric wire to pass between a plurality of rollers arranged in a zigzag configuration, the correcting device including first and second correcting devices each comprising a plurality of rollers arranged in a zigzag configuration, wherein an axis of rotation of the plurality of rollers corresponding to the first correcting device is perpendicularly disposed relative to an axis of rotation of the plurality of rollers corresponding to the second correcting device;
• a rotation controlling device arranged on an upstream-side of the correcting device and including a pair of rollers receiving the electric wire therebetween, the rollers biased in a direction toward each other so as to apply a force upon the electric wire passing therebetween;
• a guide bar, arranged on an upstream-side of the pair of rollers within the rotation controlling device, which abuts against an outer surface of the electric wire so as to position the electric wire along the horizontal direction and along a direction crossing a transfer direction of the electric wire at right angles, wherein the rotation controlling device includes a support member attached to one of the pair of rollers, the support member biased by a coil spring;
• and
• a holding part arranged positioned above the reel and between the reel and the rotation controlling device, the holding part including a ring member disposed at a height that is substantially the same as a height of the rotation controlling device, the ring member receiving the electric wire therein from the wire reel and directing the wire to the rotation controlling device along the transfer direction.
