Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A method of processing an end portion of each covered wire in a wire harness comprising the steps of: (a) holding a covered wire of the wire harness at a predetermined position distant from one free end of the wire; (b) nipping said wire from above and below by a pair of cutting edges on the free end side of said predetermined position; (c) moving said pair of cutting edges away from said predetermined position towards said free end and stopping the movement at a first position; (d) cutting an insulative covering of said covered wire by said pair of cutting edges; (e) moving said pair of cutting edges further away from said predetermined position towards said free end and stopping the movement at a second position such that the insulative covering is removed from a conductor portion of the covered wire corresponding to the first position through the second position; and (f) cutting the conductor portion of the covered wire by said pair of cutting edges at the second position.
Claim 2
Independent Claim
171 words
A method of processing an end portion of each covered wire in a wire harness comprising the steps of: (a) holding a covered wire of the wire harness at a predetermined position distant from one free end of the wire; (b) nipping said wire from above and below by a pair of cutting edges on the free end side of said predetermined position; (c) moving said pair of cutting edges away from said predetermined position towards said free end and stopping the movement at a first position; (d) cutting an insulative covering of said covered wire by said pair of cutting edges; (e) moving said pair of cutting edges further away from said predetermined position towards said free end and stopping the movement at a second position such that the insulative covering is removed from a conductor portion of the covered wire corresponding to the first position through the second position; and (f) cutting the conductor portion of the covered wire by said pair of cutting edges at the second position.
Claim 3
Dependent Claim
50 words
A method according to claim 1, further including, subsequent to the step (f), the step of (g) feeding a metal terminal member between said first position and the second position; and (h) attaching the metal terminal member to both the covering of said wire and the uncovered wire conductor portion.
Claim 4
Dependent Claim
50 words
A method according to claim 2, further including subsequent to the step of (h), a step of (i) pressing said terminal member against end portions of said wire so that both the wire and the covering of said wire are firmly gripped and severing a portion of said terminal member.
Claim 5
Dependent Claim
23 words
A method according to claim 3, further including, prior to the step (a), a step of (j) fixing the wire onto a bridge.
Claim 6
Dependent Claim
23 words
A method according to claim 4, further including, subsequent to the step (i), a step of (k) detaching the bridge from the wire.
