ABSTRACT:
Apparatus for center notching an insulated electrical conductor includes two pairs of cutting blades that circumferentially slice the insulation at predetermined locations along the insulated electrical conductor to thereby define a slug of insulation. A jaw with a knife edge is located in each of the four quadrants about the insulated electrical conductor axis. The jaws travel in respective rectangular paths in a four stroke cycle. During the first stroke the jaws are translated toward a first plane passing longitudinally through the insulated electrical conductor axis with the knife edges in a separated configuration. During the second stroke the jaws translate toward a second plane perpendicular to the first plane to close the jaws and cause the knife edges to longitudinally penetrate the insulation slug. During the third stroke the jaws are translated away from the first plane with the knife edges in the closed configuration to thereby strip the insulation slug from the conductor. During the fourth stroke the jaws translate away from the second plane to return the knife edges to the open configuration.
