An order-receiving production system 1 of a wiring harness includes a wire-producing department 14, a wiring harness-assembling department 15 and a production control department 16. The production control department 16 forwards a first ordered quantity data D1, second ordered quantity data D2 and third ordered quantity data D3, each data meeting the received ordered data D, to a resin-producing department 44, core wire-producing department 45 and additive-producing department 46, respectively. The departments 44, 45 and 46 produce a pellet, core wire and additive with the respective necessary amount, respectively, and send them to the wire-producing department 14. The wire-producing department 14 extrudes a mixture of the pellets and additive onto a circumference of the core wire while simultaneously mixing the pellets and additive so that the core wire is coated with the mixture, and sends the wire produced to the wiring harness-assembling department 15 for assembling a wiring harness.

Abstract:
An object of the present invention is to provide a method and an apparatus for marking an electric wire at a low cost. An apparatus 1 for marking an electric wire forms a band mark 21 on a part of an outer face 5a of the electric wire 3. The band mark 21 is formed along the entire circumference of the part of the outer face 5a of the electric wire 3. The marking apparatus 1 tightens the electric wire 3 in a state where a tensile force is applied in a longitudinal direction. The marking apparatus 1 includes a nozzle 35 for injecting coloring agent toward an uppermost position 10 of the outer face 5a of the electric wire 3. The nozzle 35 has an open end 42 which is opposed to the electric wire 3 and capable of passing the coloring agent. A straight line L extending between a center C1 of the open end 42 and a center C2 of the electric wire 3 lies along a vertical direction.
Abstract:
A coloring apparatus 1 includes a coloring nozzle 31 for spouting a coloring material, a signal generator 53, and a controller 19. The coloring nozzle 31 includes an electromagnetic valve 51. The signal generator 53 outputs signals for spouting the coloring material from the coloring nozzle 31 to both a CPU 62 of the controller 19 and a driving circuit 64. The CPU 62 outputs a signal for keeping the electromagnetic valve 51 open to the driving circuit 64 when a frequency of the signals from the signal generator 53 is higher than a specific frequency. When at least one of the signals from the CPU 62 and the signal generator 53 is inputted, the driving circuit 64 applies a spike voltage A and then applies a hold voltage B to a coil 40. While at least one of the signals from the CPU 62 and the signal generator 53 is inputted, the driving circuit 64 applies a spike voltage A and then continuously applies a hold voltage B to a coil 40.
