(54) Electric wire feeding apparatus and electric wire length measuring apparatus having the same


(57) An electric wire feeding apparatus is provided which is arranged to feed electric wires having an extended range of thickness. The electric wire feeding apparatus (100) is provided in an electric wire length measuring apparatus (A) for feeding an electric wire (200) derived from an electric wire storage apparatus (B) by a predetermined length to a forward machining apparatus (C). This electric wire feeding apparatus (100) comprises a lower roller (121), which is provided on the lower side of an electric wire path (111) extending in the front-rear direction for receiving the electric wire (200) to rotate around an axis extending in the width direction, and an upper roller (131), which is provided on the upper side of the electric wire path (111) to rotate around an axis extending in the width direction. The electric wire feeding apparatus is so structured that when at least one of the upper roller (131) and the lower roller (121) is energized toward the electric wire path (111), the upper roller (131) and the lower roller (121) are rotatively driven inversely to each other in such a way that the peripheral velocities of their outer circumferential faces are substantially the same, and the electric wire received in the electric wire path (111) is pressed by both the upper roller (131) and the lower roller (121) to be forwarded.
