PURPOSE: To feed automatically an electric wire to a winding device, and to protect the electric wire from a scratch and bending by a method wherein an electric wire bobbin is rotatably driven to draw out the electric wire, which is made to approach the widing position while applying tension of a yield point or more to the wire, and after the wire is cut at the prescribed length, the wire is inserted in a core.
CONSTITUTION: At a device to feed an extremely fine electric wire to the winding device of a toroidal core to be used for a magnetic head, etc., an electric wire bobbin 3 is supported rotation freely according to a mounting means E. A driving means F rotates the bobbin 3 to draw out the electric wire 2, and a bending removing means G absorbs the bending of the electric wire 2. The terminal of the electric wire 2 is drawn out by a drawing means H, and tension of a yield point or more is applied to the electric wire 2 according to a tension means I. The electric wire 2 is guided by an electric wire guide means O, and a transfer means J transfers the means H in the direction to approach the winding position. A fixing means K receives the electric wire 2 to hold the terminal, and the wire is cut at the prescribed length according to a cut means L. Thereupon the wire is inserted in a core to be wound. Accordingly, the electric wire is fed automatically, and the electric wire can be protected from a scratch and bending.
