In a method of stripping an insulated electric wire, circumferential cuts are formed in an insulating coating of the electric wire by use of circumferential cutters and then the circumferential cutters are moved in a longitudinal direction of the electric wire to separate cut pieces of the insulating coating from itself. After longitudinal cuts have been formed in the insulating coating by use of longitudinal cutters the insulating coating is removed by an air blow and an upper waste coating is sucked by a vacuum. Longitudinally cut edges of the insulating coating are abutted against shoulders which continue by intersection with inclined outer faces of cutting edges of the longitudinal cutters. A lower waste coating falls by a self weight between a pair of the longitudinal cutters. An ultrasonic horn may be employed to press the insulating coating toward the longitudinal cutters while making ultrasonic vibrations.

A rubber plug fitting apparatus includes: a rubber plug feeding unit for feeding each of rubber plugs to a rubber plug feeding port; a rubber plug holder for holding one of the rubber plugs to fit the rubber plug on a wire; and a rotary unit having a plurality of rubber plug holding rods which are fitted into each of the rubber plugs to hold the rubber plugs. The rotary unit rotationally moves each of the rubber plug holding rods between the rubber plug feeding unit and the rubber plug holder. In the apparatus, a pair of rubber plug guides are provided so as to be capable of being opened/closed at a side of the rubber plug feeding port of the rubber plug feeding unit; and guide grooves are respectively provided at positions of the pair of rubber plug guides facing the rubber plug feeding port.

A wire measuring and cutting apparatus is provided with an U-turn guide section which serves to guide a wire W being fed into a guide passage for bending the wire W in a substantially U-shaped manner. In the section , a movable guide part is constituted by a pair of guide pieces which are pivoted so as to open and close together. The U-turn guide section is provided with a displacement mechanism . The mechanism can maintain the pair of guide pieces in the closed position. While, the mechanism can displace the guide pieces for the opened position together with feeding inertia of the wire W in process of measuring the length of the wire W. With this structure, the guide pieces can be opened at high speed due to the feeding inertia in addition to the driving force of the mechanism to open the pieces and there is no need to stop feeding the wire W during the measurement of the wire W.
