Abstract:
An object of the invention is to provide an electrical cable reuse method which reduces a long time stock of cables. For assembling a wiring harness, step S1 reuses special electrical cables stocked in an electrical cable storehouse, and the cables having been colored in a first color are coated with a second color. Step 2 cuts ordinary cables and special cables each in a desired length, removes a part of a cable sheath of each cable, and fits a terminal piece to the exposed part. Step 3 connects ordinary cables and the special cables with each other. Step 4 inserts the terminal piece into a connector housing.
Abstract:
A wiring harness manufacturing method and a wiring harness manufacturing apparatus is provided, wherein manufacturing costs of a wiring harness is reduced. The wiring harness manufacturing apparatus (1) has a pair of wire stocking units (10a, 10b), a pair of cutting units (11a, 11b), a pair of joining units (12a, 12b), and a case insertion unit (13). Painting devices (14,15,16) are attached to one wire stocking unit (10a). Painting devices (17,18,19) are attached to one cutting unit (11a). Painting devices (18,19) are attached to one joining unit (12a). The painting devices (14,15,16,17,18,19) color the electric wire.
Abstract:
A wire coloring method and a wire coloring apparatus are provided. The wire coloring apparatus 1 has a coloring portion 10, a colorant-supplying portion 11, and a control unit 12. The coloring portion 10 has a mixing tank 23. The mixing tank 23 mixes first to fourth colorants B,R,Y,BL supplied from the colorant-supplying portion 11. The coloring portion 10 colors an outer surface 5a of an electric wire 3 with the mixed colorant in a mixing tank 23. The colorant-supplying portion 11 has a first to fourth adjusting valves 26,27,28,29 to increase and decrease flow rates of the first to fourth colorants B,R,Y,BL to the mixing tank 23. The control unit 12 controls opening ratios of the first to fourth adjusting valves 26,27,28,29.
Abstract:
Methods and apparatus are provided for applying a colorant material to the surface of a plastic insulation material which has been applied to an elongated material such as a metallic conductor (22) or an optical fiber which is being moved at any of a wide range of speeds along a path of travel. The coolant material is applied by nozzles which are staggered along the path of travel and which direct the colorant into engagement with the plastic insulation material at different radial directions. A first plurality of nozzles (46--46) each cause the colorant to be in a spray pattern (45) which is in the area of a plane. Advantageously, those nozzles cooperate to stabilize the conductor and prevent undulations thereof as the conductor is moved along its path of travel. A second plurality of nozzles (50--50) cause the colorant to be in a solid conical pattern (53). The first and the second pluralities of nozzles are effective to cause substantially all the surface area of the plastic insulation on successive increments of length of the conductor to be covered with the colorant material.
Abstract:
An elongated body, such as insulated wire, is drawn through a marking station where a relatively high viscosity coherent stream of ink is sprayed back and forth transversely of the wire. The ink flow is bent around at the tangent of the wire to the far side of the wire by surface tension so that a complete circumferential band is formed by a single jet spray. A constant flow pump is used in conjunction with a pressure gauge to actuate an alarm should pressure in the ink supply rise above a given threshold due to increased ink viscosity or nozzle blockage. Variation in marking spacing and/or color can be accomplished without stopping production.
Abstract:
A device for a circumferentially closed arrangement of a printed piece of tubing around a prolate object includes: a guide passage for conveying the piece of tubing along a longitudinal direction thereof and to open piece of tubing during a conveying movement under an effect of flexing forces; and at least one sensor aligned transversely to the longitudinal direction, the at least one sensor detecting an end of the piece of tubing, which end is trailing during the conveying movement, by exposing the at least one sensor, and detecting the prolate object introduced into the piece of tubing, which is opened, along the longitudinal direction against the conveying movement at an exiting of a trailing end by blocking the at least one sensor.
Abstract:
A method according to the teachings of the present disclosure may include disposing a sheath around a conductor assembly, with an outer surface of the sheath defining spaced apart crowns and valleys. An outlet of at least one ink jet print head may be positioned adjacent the sheath at an angle of 60 degrees to 120 degrees with respect to a longitudinal axis of the sheath. The method may also include using at least one ink jet print head to print marking indicia on the sheath, the marking indicia indicating at least characteristic of the electrical cable assembly.
Abstract:
Systems and methods to apply an on-demand color scheme to a cable are described. The systems and methods include the application of a plurality of colored coating fluids to an outer cable layer.
