A braid processing device trims an end portion of an exposed braid of a braid-shielded cable including a cable center portion (e.g., two insulated wires), a braid that covers an outer circumferential surface of the cable center portion, and a sheath that covers an outer circumferential surface of the braid, the exposed braid being exposed from the sheath. The braid processing device includes a braid raising mechanism that raises the exposed braid from the cable center portion toward an outer circumferential side, and a shearing mechanism. The shearing mechanism includes an outer blade that has an annular outer cutting edge, an inner blade that has an annular inner cutting edge, the annular outer cutting edge and the annular inner cutting edge being capable of shearing the exposed braid therebetween, and a blade driving portion that relatively moves the inner blade toward the annular outer cutting edge.

A method for laying multiple conductors in a container may be provided. The method may comprise receiving the multiple conductors at a monitoring station; receiving the multiple conductors at a drive; and receiving the multiple conductors at the container.

A wire bonding system attaches wires to a solar cell wafer. The wire bonding system includes a feed tube through which a wire is drawn. Rollers contact the wire through openings in the feed tube to facilitate movement of the wire. The wire bonding system includes a soldering heater tip and a wire cutter. The solar cell wafer is placed on a platform, which moves the solar cell wafer. The system has multiple lanes for attaching multiple wires to the solar cell wafer at the same time in parallel operations.

A process for manufacturing finished wire and cable having reduced coefficient of friction and pulling force during installation, includes providing a payoff reel containing at least one internal conductor wire; supplying the at least one internal conductor wire from the reel to at least one extruder; providing the least one extruder, wherein the at least one extruder applies an insulating material and a polymerized jacket composition over the at least one internal conductor wire, wherein the polymerized jacket composition comprises a predetermined amount by weight of nylon; and at least 3% by weight of a silica providing a cooling device for lowering the temperature of the extruded insulating material and the polymerized jacket composition and cooling the insulating material and the polymerized jacket composition in the cooling device; and, reeling onto a storage reel the finished, cooled, wire and cable for storage and distribution.

It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.

A flat cable 10 according to the invention has a plurality of arrayed conductors 11; and an insulating layer 12 covering the periphery of the conductors 11 with a coating film, in which the insulating layer 12 includes a plurality of layers, the outermost layer 13 of the insulating layer 12 and the innermost layer 14 contacting the conductors are both formed from polyphenylene sulfide-based resins, and the melting point of the polyphenylene sulfide-based resin constituting the innermost layer 14 is lower by 5 C. or more than the melting point of the polyphenylene sulfide-based resin constituting the outermost layer 13.

A rotary body including a drum and a wire support member winds a wire by rotation. A spacer is provided on the rotary body and is displaceable to a first position and a second position in the rotary body. When the spacer is in the first position, the wire is wound on the rotary body not via the spacer, and hence the wire is wound with the first diameter. When the spacer is in the second position, position, the wire is wound on the rotary body via the spacer, and hence the wire is wound with a second diameter larger than the first diameter.

A method for applying a label to an electrical cable having an outermost sheath with convolutions defining alternating peaks and valleys, the method including attaching the label to the sheath. The label includes a label substrate, the label substrate includes an attaching side, the attaching side being attached through an adhesive; and the label attaches to the peaks and spans across the valleys and circumferentially wraps around the sheath.

A method of laying an optical fiber comprises providing a continuous optical fiber, a first segment of optical-electrical hybrid cable having a first fiber receiving tube, and a second segment of optical-electrical hybrid cable having a second fiber receiving tube. The optical fiber is laid into the first fiber receiving tube using an air-blowing device. A leading end of the optical fiber is fixed in a transfer apparatus after the leading end passes through an outlet of the first fiber receiving tube. A portion of the optical fiber which has passed through the first segment is wound in the transfer apparatus until the optical fiber is completely laid in the first segment. The leading end of the optical fiber is detached from the transfer apparatus. The portion of the optical fiber which has passed through the first segment is laid into the second fiber receiving tube using the air-blowing device.
