Abstract
In a method of peeling an intermediate portion of an insulative covering from a coated electric wire, the electric wire is subjected to an annular slits forming step, an intermediate portion fixing step and lateral slit forming step in any order. After all of the above steps has been finished, the intermediate portion of the covering is separated from the electric wire with the intermediate portion remaining fixed. Therefore, variations in the peeling length is prevented and the intermediate portion-peeling can be carried out without damaging a conductor of the electric wire. Further, the method can be applied even to a very narrow and thin electric wire.

A method of peeling an intermediate portion of an insulative covering from a covered electric wire in a peeling position, said covered electric wire having a longitudinal axis, comprising the steps of:
- placing and temporally fixing said covered electric wire in said peeling position;
- forming annular slits at opposite ends of said intermediate portion in said covering;
- fixing said intermediate portion in said peeling position from opposite sides thereof in a direction perpendicular to said axis;
- forming a lateral slit in said intermediate portion in parallel relation to said axis;
- and
- separating said intermediate portion from said electric wire with said intermediate portion remaining fixed in said peeling position from said opposite sides thereof, after all of said annular slits forming step, intermediate portion fixing step and lateral slit forming step have been finished.
An apparatus for peeling an intermediate portion of an insulative covering from a covered electric wire placed in a peeling position, said covered electric wire having a longitudinal axis, comprising:
- means for placing and temporally fixing said covered electric wire in said peeling position;
- means for forming annular slits at opposite ends of said intermediate portion in said covering;
- means for fixing said intermediate portion in said peeling position from opposite sides thereof in a direction perpendicular to said axis;
- means for forming a lateral slit in said intermediate portion in parallel relation to said axis;
- and
- means for separating said intermediate portion from said electric wire with said intermediate portion remaining fixed in said peeling position from said opposite sides thereof, after said annular slits are formed at said opposite ends and said lateral slit is formed in said intermediate portion.
