- 46 - SHUTTLELESS TOROIDAL CORE WINDER ABSTRACT Disclosed is an apparatus for simultaneously winding multiple strands of wire into turns about a toroidal core in rapid fashion. The apparatus in- cludes a U-shaped wire receiving channel having a semi-circular portion with a gap and a pair of open- ended legs. The ends of the channel legs are po- sitioned adjacent opposite sides of a rotatably mounted drum which is driven by a resilient endless belt engaging approximately one half of its annular outer surface. A toroidal core is supplied and rigidly supported in the gap by a core feeding mechanism. A grooved gap crosser is thereafter extended through the central opening of the core to bridge the gap and complete the channel. A pair of pinch roller type feed/brake mechanisms propel and guide the leading ends of the wires into the channel, through the core opening, and up one channel leg to the drum. There the wires are frictionally held between the drum and the belt and they are positively driven into the other channel leg, through the core opening, and back to the drum. Continued feeding of the wire results in the for- mation of a coil having a plurality of vertically stacked, oval-shaped loops which extend through the core opening and are alternately made of dif- ferent ones of the wires. Thereafter, staggered braking of the trailing ends of the wires causes the loops to be successively peeled radially inwardly from the channel and the drum as the coil is con- tinuously circulated. The loops are tightened into - 47 - turns about the core as it is slowly rotated about its axis by the core feeding mechanism. First and second shear mechanisms cut off the trailing and leading ends of the wires at the beginning and end of the winding operation, respectively.
