Abstract: An apparatus for peeling and twisting an electric wire having an insulating coating comprises a machine frame, a shaft rotatably mounted on said frame and being adapted to be driven by a motor, a machine body movably mounted on the shaft and an elastic member for urging the machine body to an end position on the shaft. The shaft includes wire clamping cam, insulating coating cutting cam, twisting cam and cut insulating coating disengaging cam. A wire clamping means is mounted on the frame and is following the clamping cam. The machine body includes an insulating coating cutting means which follows the insulating coating cutting cam for cutting the insulating coating of the wire, a conductor twisting means which follows the twisting cam for twisting the conductors of the wire and a cut insulating coating disengaging means which follows the disengaging cam for disengaging the insulating coating which has been cut.
