Method and apparatus for preventing distortion of a wire harness by marking the harness with a contrasting straight line

摘要

A wire harness including a plurality of wires surrounded by an outer tube wherein the outer surface thereof has an axial line drawn thereon. If the harness becomes twisted during handling and before installation, the line becomes helical and, since it is of contrasting color to that of the surface to which it is applied, it is readily visible to the installer. To correct the undesirable twisting, the wire harness is counter-rotated until the line becomes straight once again. The device can then be installed in the usual manner. If installation of a twisted wire harness is attempted, the additional distances which the branches must travel will make them too short to reach their intended connection points. A device for applying the line to the outer surface is also disclosed.
