ABSTRACT:
A cable jacket slitting apparatus automatically pierces a cable jacket to a controlled depth at a tangent between two adjacent wires and automatically follows the tangent path as the jacket is slit. Two semicylindrical cam halves, (1, 23) disposed in aligned opposition within a housing (30), include longitudinal recesses (2, 24) having grooved sidewalls (4, 26) which conform to the helical contour of an electric cable jacket (5). The two cam halves are driven into mutual contact by a contoured surface (37) on the housing sidewall (31), the two cam half recesses forming a passage (48) which loosely grips the cable within the grooves in the sidewall. One of the cam halves carries a cutting rod (7) with a knife end (8) which pierces the cable jacket between a pair of adjacent wires. As the cable is drawn through the passage, the cam halves rotate about the longitudinal axis of the cable, helically slitting the jacket in a continuous helical direction around a longitudinal axis between a pair of adjacent wires.
