A wire stripper part or assembly uses two or more elements for a blade roller, with one element being a cutter, and the other element or elements being a guide element that keeps the wire aligned with the cutter. A tri-blade self-centering wire stripper knife is also described. A wire stripper has: a structural frame; parallel rollers mounted on the structural frame to rotate relative to one another, one of the parallel rollers being a feed roller and the other being a blade roller; and in which the blade roller has a wire cutter comprising a cutting blade and one or more circumferential guide shoulders, with the wire cutter aligned with a wire-gripping portion of the feed roller to define a wire-cutting zone. Methods of use are described.

A pneumatic stripping tool is provided. A top end of a main base is connected with an upper gland through screws; a middle part of a top end of the upper gland is connected with a handle through screws; one end of the upper gland is connected with a pneumatic-wrench fixing seat gland through screws; a pneumatic wrench is connected between the handle and the pneumatic-wrench fixing seat gland; the outer side of one end of the pneumatic wrench is connected with a power wrench sleeve; mounting holes are formed in portions of the main base which are corresponding to the power wrench sleeve; the inner side of one end of the power wrench sleeve is connected with a bottom wheel; and the bottom wheel extends into an inside of the mounting hole.

A shield foil removing device includes an opening and closing chuck configured to accommodate two wire cores surrounded by a shield foil in a space having a rectangular cross section orthogonal to an electric wire longitudinal direction, which is formed by closing, in such a direction that a longitudinal direction of the rectangular space and an arrangement direction of the two wire cores in a cross section coincide with each other, compresses the shield foil in a direction orthogonal to an arrangement direction of the two wire cores by reducing the rectangular space by a closing operation, and brings the shield foil into close contact with outer peripheral surfaces of the two wire cores to secure a gap continuous in a longitudinal direction of the shielded electric wire between both of outer peripheral curved surfaces adjacent to each other of the two wire cores and the shield foil.

The invention relates to an apparatus for unravel-ling wire ropes (3), which are made up of a complex of different materials, having a peeling device (1) with an opening (5), through which a core (9) of the wire rope (3) passes along a through-feed axis (D) and a through-feed direction (Z), while an outer portion (10) is separated, said peeling device (1) comprising a mandrel (4) through which the opening (5) passes axially, with at least one rotatable cutting wheel (12) being provided next to the mandrel (4), which wheel has on the circumference thereof at least one blade (13) and the axis of rotation (R) of which wheel is substantially transverse to the through-feed axis (D), characterized in that a cut-ting profile (6) of the blade (13) or a common cutting profile (6) of the blades (13) is concave in form.

According to typical inventive practice, a cable is grasped by a Kellum grip and is positioned through the topside “V”-notch of an “M”-structure. Two wires engage pulleys and a ratchet distanced from the pulleys. The pulleys are joined with a grip plate, attached at an axial end of the Kellum grip. The ratchet is joined with a ratchet plate, proximate and/or attached to the “M”-structure. The “M”-structure has joined therewith three blade wheels having cutting orientations in the same linear direction. The blade wheels are situated interiorly and perpendicularly in correspondence to the geometric sides of the inverted triangle defined by the “V”-notch. Each blade wheel is adjustable to suit the diameter of the cable positioned through the “V”-notch. Ratcheting of the wires moves the ratchet plate and hence the “M”-structure, resulting in creation via the blade wheels of three parallel slices in the cable along its axis.

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 cable foil layer processing equipment includes a rack, a knife holder installed on the rack, a plurality of cutters movably installed on the knife holder and arranged in a crisscross manner in a vertical plane, and a linear moving mechanism configured to move linearly in a horizontal direction parallel to an axial direction of a cable. The rack is installed on the linear moving mechanism so as to move linearly in the horizontal direction along with the linear moving mechanism. The cutters clamp a foil layer of the cable in a radial direction of the cable. The linear moving mechanism drives the knife holder to move in the horizontal direction so as to cut the foil layer of the cable into a plurality of equal parts.

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).
