Abstract: A twist correction device includes an untwisting mechanism and a controller, the untwisting mechanism being configured to grip a multi-core twisted wire by means of a pair of gripping elements, wherein the pair of gripping elements is configured to slide together toward a tip side of the multi-core twisted wire while performing a relative stroke position offset movement of the pair of gripping elements in a direction of untwisting for untwisting the multi-core twisted wire, wherein when the pair of gripping elements is positioned on an exposure side end side of the multi-core twisted wire, the controller is configured to perform operation control with a smaller gripping force in a twist gripping direction as well as a smaller operation force and a smaller position offset amount for the stroke position offset movement than when the pair of gripping elements is positioned on the tip side.

Abstract: Terminal crimping device and terminal crimping method is provided that collectively crimp-connects a terminal to an electric wire while suppressing displacement of the terminal at a crimp position. A terminal crimping device includes a cutting part configured to cut from the carrier each of the two or more terminals belonging to one terminal set at one end side in the terminal coupled body; a terminal conveyance part configured to convey the two or more terminals cut at the cutting part to a crimp position corresponding to the predetermined interval while adjusting a terminal interval of the two or more terminals to an arrangement interval of the covered electric wire at the crimp position in a conveyance direction (longitudinal direction) of the terminal coupled body; and a crimping part configured to collectively crimp-connect to the electric wire each of the two or more terminals conveyed to the crimp position.

Abstract: A core wire deformation jig and a method for deforming a plurality of core wires which are exposed from an end of a multi-core cable for a further working step. The jig includes a first clamping unit for clamping the core wires aligned on the arranging plane in a first clamping direction intersecting the arranging plane, a separation pin for separating the core wires, wherein the separation pin is inserted between the core wires in a insertion direction parallel to the first clamping direction, and a second clamping unit for providing bends to the core wires by clamping the core wires in a second clamping direction parallel to the arranging plane and intersecting the plurality of core wires and applying a pressure on the core wires, with the separation pin inserted between the core wires.

Abstract: A wire harness manufacturing method includes manufacturing a standard-size electric wire in which a terminal-equipped electric wire which is connected to a terminal is manufactured in lot units for each type, clamping the terminal-equipped electric wire to a pair of electric wire clips, dispensing a plurality of terminal-equipped electric wires respectively clamped by the electric wire clamps to electric wire holders, storing the plurality of the terminal-equipped electric wires temporarily in the electric wire holders, locking the both end portions of the terminal-equipped electric wire to an electric wire clip tool respectively and aggregating an electric wire group configuring a wire harness at the electric wire clip tool to form a harness set, and detaching the end portions of the terminal-equipped electric wire from the harness set and inserting the terminal connected and fixed into a terminal accommodating chamber of a connector housing.
