Abstract
PURPOSE: To simply and mechanically twist-joining broken ends of a wire electrode by a twist-joining device disposed in or in the vicinity of a path of the wire electrode.
CONSTITUTION: During an electric-discharge processing operation, a wire electrode 8 is payed off by a capstan 9 against the braking force of a brake roll 13. When the wire electrode 8 is broken, for example, in a position 8a, a tension roll 23 is lowered to actuate a limit switch 26 for a wire electrode breakage detector 20 via an arm 24a to stop the movement of the wire electrode 8. In such a case, ends of two portions 8b, 8c of the wire electrode 8 are gripped by a grip means 27. The free end of the portion 8b is then held in a notch 36a in a rubber roll 36 of a twist- joining device 34. The rubber roll 26 is thereafter rotated via a drive wheel 39 to twist-join the portion 8b to the portion 8c.
