Title: DEVICE FOR PRODUCING STRANDED ELECTRICAL WIRE AND METHOD FOR PRODUCING STRANDED ELECTRICAL WIRE
Abstract:
The purpose of the present invention is to more reliably eliminate twists in individual electrical wires when twisting together a plurality of electrical wires. This device for producing a stranded electrical wire twists together a plurality of electrical wires and is provided with: an electrical wire intermediate holding section that movably holds an intermediate section of a plurality of electrical wires in the direction of extension thereof in a fixed arrangement state along the direction of extension; a stranding rotation drive section that rotationally drives the electrical wire intermediate holding section; a movement mechanism that causes the electrical wire intermediate holding section to move from one side toward the other side in the direction of extension while said electrical wire intermediate holding section is rotated by the driving force of the stranding rotation drive section; and an end section rotation mechanism that rotationally drives the plurality of electrical wires as a whole in the same direction as the direction of rotation of the electrical wire intermediate holding section on the other side from the electrical wire intermediate holding section in the direction of extension and meanwhile rotationally drives each of the plurality of electrical wires in the opposite direction from the direction of rotation of the electrical wires as a whole.
