ABSTRACT:
An improved method and apparatus for winding wire onto toroidal cores in which the wire is fed into a circular channel to form a coil that passes through the core repeatedly. The wire is fed to the apparatus by a cylindrical capstan for creating tension to straighten the wire. The wire is circulated in the channel by pairs of synchronously driven rollers, with one roller pair gripping the wire more loosely to permit slippage. The channel has a narrowed width adjacent to the rollers to control wire deflection. A movable feed track exit allows smooth feeding of wire into the channel, while permitting increased capacity by sliding the exit inward of the growing coil. A variable transmission adjusts the rate at which the wire is fed into the channel relative to the rate at which it circulates. A split block wire cutter is adjustable to compensate for cutter wear.
