Abstract: A method for cutting a coil conductor in which a halted conductor wire 2 to be formed into a coil is served by cutting edges 5A, 5B, while simultaneously advancing a cutting edges downstream in the feed direction of the wire. Thus, a pushing back force against the conductor wire and its attendant deformation is prevented when cutting it, whereby the dimensions of the conductor wire are stabilized.

Abstract: In an armature coil conductor arraying apparatus, a cylindrical coil guide tool 25 has a plurality of inner insertion holes or grooves 23a into which inner legs of coil conductors 2 are inserted and a plurality of outer grooves 24a provided radially outwardly of the inner insertion holes in respective outer peripheries of cylindrical inner coil holder 23 and cylindrical outer coil holder 24. A cylindrical holder 26 rotatable about an axis of the coil guide tool is disposed radially outwardly of the coil guide tool, and mounts a plurality of inclined settling plates or guides 29 for guiding outer legs of the coil conductors into the outer grooves when the holder is rotated.

Abstract: A clamping apparatus for a coil can exactly position a plurality of pre-assembled U-shaped wires at predetermined locations and clampingly hold their positions in a precise manner with extreme ease to thereby ensure smooth insertion of the wires into an iron core while avoiding inadvertent deformations of or damage to the wires upon assembly. A plurality of clamp pins are disposed on the support disk for rotation relative thereto and spaced from each other with predetermined circumferential intervals, each of the clamp pins being movable in a radial direction of the support disk and having a tapered tip end directed toward the central axis of the support disk. Each of the tip ends has two pairs of engagement grooves formed therein. A first drive mechanism drives the clamp pins to move in a direction radially of the support disk by a predetermined radial distance whereby the tapered tip end of each clamp pin is adapted to move into or out of adjacent ones of the U-shaped winding wires.
