Abstract: A stripping apparatus for stripping coated electric wires b has a pair of clamping plates movable into and out of contact with each other and provided with cutting edges formed at a constant pitch in their opposing contactable edges. The corresponding cutting edges in both clamping plates cooperate with each other in defining, when the clamping plates are held in contact with each other, cutting gaps of different sizes. The clamping plates are adapted to clamp and sever, at their cutting edges, the end portion of the coating d on the coated electric wire at least partially. Means are provided for causing a relative movement between the coated electric wire and the clamping plates thereby to remove the severed end portion of the coating from the core wire of the coated electric wire.
