After cutting the sheathed wire 12 into the sheathed wire 12 and making a cut in the sheath, the blades 22 and 22 'are opened to return to the original state or the wire guide means 18 holding the sheathed wire 12 in a state of being bitten.
When the pressure of the air cylinder 54 is increased above a predetermined value by switching the solenoid valve to increase the gripping force, and the wire guide means 18 is further retracted in this state, the coating of the coated electric wire 12 is caused by the gripping force of the wire guide means 18. The coating can be pulled off and stripped. In this case, the air cylinder 66
It is necessary to be able to switch the stroke of the two steps.

The upper and lower wire guide members are slidably and frictionally gripped while being aligned at a predetermined pitch, and the wire guide member is moved so as to separate from the arrangement jig while sliding on the covered wire. Tension can be applied to
Therefore, when the upper and lower blades are cut into the coating and the coating is cut and the coating is removed, the coating of the coated electric wire can be easily peeled off with the correct processing dimensions, so that the coating of a plurality of discrete coated electric wires can be performed. At the same time, there is a practical benefit that the terminal treatment of the coated electric wire can be performed with high accuracy and high workability.
