Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

A peeling apparatus 1 includes a first peeling die and a second peeling die respectively including a pair of cutting blades 251 that peels the insulating film by being moved in a direction perpendicular to an axial direction of the conductive wire material 2 to cut the insulating film, and a support die 253 that supports a side surface of the conductive wire material 2 from a downstream side in a moving direction of the cutting blades 251 at the time of cutting by the cutting blades 251, the support die 253 of the first peeling die including a convex portion 2533 protruding toward the conductive wire material 2.

A cable stripping tool removes a cable jacket from a cable to expose a plurality of neutral wires, the cable stripping tool including a housing, a frame coupled to the housing, a mandrel extending from the housing and rotatable about a first axis, and a motor supported by the housing and operably coupled to the mandrel to rotate the mandrel about the first axis. The frame supports the cable stripping tool on the cable and the mandrel engages a starter wire of the plurality of neutral wires. Rotation of the mandrel by the motor winds the starter wire around the mandrel such that the cable jacket is torn by the starter wire. The cable stripping tool further includes a termination tool configured to score the cable jacket at a desired distance from an end of the cable.

A method of producing shaped parts includes drawing insulated flat material with a draw-in device and processing in a wire processing machine to form the shaped part material; separating the shaped part from supplied insulated flat material by cutting, wherein before the shaped part is separated, part of the insulation layer is removed in a portion of the flat material; and synchronously with feeding stripping tools on each side of the flat material, feeding at least one supporting element toward the flat material.

A cut-away cutting tool has two slit forming blade portions and a peeling blade portion interposed between the two slit forming blade portions. The two slit forming blade portions respectively form slits on an insulating coating of a flat conductor wire. On the other hand, the peeling blade portion peels off a portion of the insulating coating between the slits formed by the two slit forming blade portions.

A removing apparatus (2) includes a first removing section (11) and a second removing section (12). The first removing section (11) includes a rotating disk (15) and a driven roller (16). The rotating disk (15) has a pair of left and right first to fourth left and right removing blades (21) to (24) attached thereto. When the rotating disk (15) rotates in a counterclockwise direction, a coil conductive wire (3) sandwiched between the rotating disk (15) and the driven roller (16) is transferred in a transfer direction. When the rotating disk (15) rotates in a counterclockwise direction, the left and right side surface portions of the insulating coating (4) are removed by a blade portion (21b) of a pair of left and right first left and right removing blades (21).

A manually-operated wire stripper is a device for cutting and removing the electrical insulation from an electrical wire. The device includes a base plate onto which a first mounting plate and a second mounting plate are perpendicularly mounted. A first rod is rotatably mounted through the first mounting plate and the second mounting plate. A cutting assembly is mounted for longitudinal movement to the first rod and may be moved into position such that a blade of the cutting assembly is aligned with a selected slot from a plurality of wire slots traversing through the base plate. An electrical wire may be stripped by inserting the electrical wire through the selected slot, creating a cut in the electrical insulation with the blade, and then manually pulling the electrical wire through the selected slot to remove the electrical insulation along the length of the electrical wire.

A disclosed wire stripper device comprises a sectioned shaft having a removable section thereof configured to have a first joint between a first bearing end of the shaft and a midsection and a second joint between the midsection and a second bearing end of the shaft. The first joint and second joints comprise a midsection portion at each joint and a complementary shaft portion of the respective first and second bearing ends. A first removable coupling is configured to hold the first joint portions together and a second coupling configured to hold the second joint portions together during a rotation of the sectioned shaft and allow a decoupling of the first and second joint portions otherwise. A method for the maintenance of a wire stripper device is disclosed comprising removing a section of a sectioned shaft by removing the coupling collars retaining the joints of the shaft sections.

A coat removing method of removing a coat of a coated optical fiber 3 made of a glass fiber 3a and the coat of polyimide resin 3b covering the glass fiber 3a includes holding the coated optical fiber 3 with fiber clamps 5 and 7 at two locations spaced by a predetermined distance in a length direction of the coated optical fiber 3, applying tension to the coated optical fiber 3 in the length direction, pressing a coat removal blade 29 to the coated optical fiber 3 in the tension-applied state in a direction crossing the length direction, to bend the coated optical fiber 3, and moving the coat removal blade 29 in the length direction along the coated optical fiber 3 in the bent state, thereby removing the coat.
