Abstract
A leading end portion of a thermoplastic jacketed cable is desheathed by applying heat from a movable, continuously operating annular radiant heat source to heat-soften a narrow (e.g., on the order of 1/8 of an inch or less) annular section of the jacket without contacting the jacket. A gripper slide assembly is moved parallel to the cable to grip and apply tension on the leading end portion of the jacket to separate the jacket along the heat-softened section and to remove the leading end portion of the jacket from the cable. After the slide assembly has moved sufficiently to cause separation of the jacket, the heat source is moved axially of the cable from the area of jacket separation so as to preclude damage to the insulation on the cable conductors and to permit the heat softened material of the jacket remaining on the cable to reharden and form a smooth edge along the line of separation. In another embodiment of the invention, the heat source may be energized and subsequently de-energized to achieve the heat-softening of the jacket and to preclude damage to the insulation on the cable conductors.
