ABSTRACT:
Apparatus for feeding an insulated electrical wire, or the like, axially with respect to a transverse plane in which a single pair of blade cutting edges are supported for movement toward and away from the axis of the wire. Each blade has a continuous cutting edge forming the periphery of an opening through the blade. The wire is advanced a predetermined distance through the aligned blade openings by a pair of conveyors on opposite sides of the plane of the blade edges. The blades are moved in opposite directions to sever a premeasured length of wire from the supply by first portions of each blade edge. The severed wire portion is then moved by the conveyors to a second axial position and the blades are again moved to cause second portions of the cutting edges to pass partially through the layer of insulation, stopping before contacting the conductor. Axial movement of the wire then causes the engaged blades to sever a slug of insulation and strip it partially or fully from the conductor. The rollers of both conveyors which are nearest the plane of the blade edges are of smaller diameter than the distal rollers, thereby permitting the conveyors to extend and support the wire at positions closer to the blades than otherwise possible.
