PCT No. PCT/JP89/00446 Sec. 371 Date Dec. 29, 1989 Sec. 102(e) Date Dec. 29, 1989 PCT Filed Apr. 27, 1989 PCT Pub. No. WO90/12672 PCT Pub. Date Jan. 11, 1990.In a wire electrode feeding device in a wire cut electric discharge machine, a roller unit having a fluid inlet, a fluid outlet, and a rotor which is rotated by fluid supplied thereinto, a guide pipe connected to the fluid outlet of the roller unit, and a wire electrode winding mechanism provided near the fluid outlet of the guide pipe are used to convey and remove the wire electrode which is conveyed through a lower electrode guide and an electric feeder. As the fluid is supplied into the roller unit through the fluid inlet, the rotor is rotated, so that the direction of movement of the wire electrode is changed, and the wire electrode is conveyed through the fluid outlet of the roller unit and the guide pipe to the wire electrode winding mechanism by the fluid, thus being discharged out of the machine.
