Braided wire manufacturing method and braided wire manufacturing apparatus

摘要

Provide is a braided wire manufacturing method and a braided wire manufacturing apparatus which can produce a braided wire accurately braided without distortion. In a braided wire manufacturing apparatus, a plurality of conductive wires fed from a wire feeding mechanism are braided into a braided wire from a convergence position after passing through a mesh hole die, and the braided wire after passing along a guide roller is wound up using a capstan unit. The guide roller has a guide width for horizontal direction restriction so that movement of the braided wire in the horizontal direction falls within a predetermined restriction width from an ideal center position. The guide roller is provided at a height of a braid pitch of the braided wire in the perpendicular direction from the convergence position as a second feature.

1. A braided wire manufacturing method in which, after obtaining a braided wire by braiding a plurality of wire members, the braided wire is wound up using a take-up unit, the method comprising:
feeding the plurality of wire members from a wire feeding mechanism toward a hole die having a circular opening; passing the plurality of wire members through a path restricting section provided on a moving path which is a path of the plurality of wire members that extends along a first direction passing through the hole die up to the take-up unit, the plurality of wire members being braided into the braided wire at a convergence position before passing through the path restricting section, the convergence position being defined at a predetermined height above the hole die, and set based upon a size of the circular opening of the hole die; and winding up the braided wire after passing through the path restricting section using the take-up unit, wherein: the path restricting section is capable of performing a second direction restriction so that movement of the braided wire in a second direction, which is perpendicular to the first direction, falls within a predetermined restriction width from an ideal center position that coincides with a winding position of the braided wire by the take-up unit, and the path restricting section is provided at a formation height in the first direction at substantially a braiding pitch length of the braided wire above the convergence position.
