Abstract: A wire harness and a method of and apparatus for manufacturing the same is disclosed. The present wire harness comprises a plurality of electric wires, constituting its trunk line portion and branch line portions, laid on a wiring board so as to form a desired pattern and a clamp chain, formed of a plurality of wire clamps arranged in parallel at predetermined pitches, attached to the edge portion at least at one side of the wiring board, in which the electric wires are locked to specific wire clamps of the clamp chain, and thereby, both end portions of the electric wires are arranged so as to be in parallel at predetermined pitches and projecting from the edge portion.

Abstract: A method and apparatus for automatically producing a wire harness. A plurality of wiring blocks are arranged on a workbench. Each wiring block has a wire clamping section, a wire cutting section, and a terminal press attaching section. The wire cutting section and the terminal press attaching section can be separated from the wire clamping section. This structure makes it possible to automate a series of operations including wire cutting, wire peeling, and terminal attaching operations.

Abstract: A wire harness manufactured by a new method and a new apparatus is provided. A covered wire paid out from a selected one of reels is extended in a predetermined lay-out and fixed. The thus fixed wire is cut-off from the reel. Then, another wire is paid out from another reel for arranging it in a juxtaposing relation to the previously laid-out wire and cut off from the reel. After repeating the above steps, the arranged wires are tied up to form a wire harness. There is also provided a device which puts the above method into practice, thereby reducing complicated assorting work involved in the manufacture of a wire harness. A method and a device for automatically uncovering end portions of each wire of the wire harness and attaching terminals thereto are also provided to greatly increasing the productivity.
