  • Patent number: 6886438
    Abstract: An apparatus and method for measuring the length of a cable for obtaining a reference measurement wherein a belt drive advances the cable through a first gripper until the cable is under separating/stripping cutters which cut the cable. The cable is advanced by a length measured by the belt drive, a leading cable-end being passed under a cable-end detector, and the cable is held tightly by the first gripper and with a linear backward movement, the cable is withdrawn until the leading cable-end leaves the cable-end detector. A correction factor is calculated by a control from the distance between the separating/stripping cutters and the cable-end detector and from the travel of the first gripper during the backward movement.

    Abstract: A clamping unit, cutting unit, and drive unit are installed in a main body that may be carried with one hand. The cutting depth of the cutting unit may be adjusted by an adjusting wheel. A handle unit for carrying the main body is shaped and positioned such that a covered electric wire may be raised, and the main body placed in the area under the wire without interfering with the handle unit. An insertion hook holds the covered electric wire securely before the clamping unit, cutting unit, and drive unit are driven. When the stripping unit is actuated, the clamping unit clamps an intermediate portion of the wire, then the cutting unit cuts the covering of the covered electric wire to a predetermined depth, then the drive unit pushes the cutting unit (and thereby a portion of the wire covering) away from the clamping unit.

  • Patent number: 5865085
    Abstract: An improved apparatus for removing surrounding insulation from an insulated electrical conductor has a pair of matched frustoconical cutter wheels mounted on a cutter shaft. The cutter wheels incorporate a cutter edge and a beveled outer slope. The cutter wheels are spaced apart by an interchangeable cutter spacer. When properly set up the cutter spacer is of a size so that the cutter wheels flank the conductor of the wire being stripped, cutting only the insulation portion of the wire. The cutter edges pierce and cut the insulation while the slope of the cutter wheels urge the insulation away from the conductor. A pinch roller assembly stabilizes the wire as it passes by the cutter wheels. A diverter is mounted in close proximity to the cutter spacer in a tangential fashion to divert and clear away any insulation that clings to the cutter spacer during operation.

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.

  • Patent number: 5543000
    Abstract: A radiating cable comprises a core having a center conductor bonded to, centered in, and supported by discs of dielectric material. A sleeve of dielectric material is extruded over the discs and thereby bonded thereto to form a plurality of sealed, coaxial, dielectric chambers. A tubular outer conductor is bonded in concentric relation to the sleeve. In a continuous process, at least one slot is formed in the outer conductor by a cutting operation and an outer jacket is extruded over the outer conductor. In a preferred embodiment, the outer conductor is made of an aluminum tube and two circumferentially equally spaced slots are formed therein by removing between 10 and 35% of the aluminum material. The width of the resulting slots may be configured so that a joint is formed in the slot between the insulating sleeve and the outer jacket, thus obviating the use of adhesive in bonding the outer jacket to the cable.

The box end wall abuts a plate extending perpendicular to the end wall and parallel to the cutting wheel. A slot through the plate has side and bottom walls extending parallel to the cutting wheel axle. In use, a cable in the slot extends axially towards and over the cutting wheel. A first cut is thus made in the cable in a plane perpendicular to the cable axis. By positioning the cable to extend axially parallel to the plate, an axially extending second cut is made. By extending the first cut entirely around the cable and intersecting the two cuts, a section of the cable sheathing is removed.
