Abstract
Abstract A rotary wire stripping machine for removing insulation from the end of an insulated wire including a reciprocating carriage for supporting a rotating head member which has a pair of cutting blades and a guide means for positioning the end of the wire to be stripped. The rotating head member includes a central chamber for receiving the end of an insulated wire and cam means for forcing the blades into contact with the wire to cut the insulation when the carriage is moved to a first position and to pull the insulation off the end of the wire when the carriage is moved to a second position. The machine also includes a means of securely clamping the wire and a means for straightening the wire so that it may be received within the rotating head member.
