A method for winding wire strands onto toroidal cores in which a length of wire is fed along a radially inwardly facing channel in an arcular guide to form a loop. As the leading end of the wire completes this loop it hugs the channel's radial boundary to form a second loop radially inside the first as the wire feeding continues. A gap is provided in the radial boundary of the channel for receiving the core with the core's central aperture in this gap so as each loop is formed the wire in that loop passes through the core. The upper and lower boundaries of the channel are spaced apart so as to maintain the loops in a single concentric layer around the guide and through the core. When enough wire has been fed the feeding is stopped, but the movement of the loops around the guide continues and winds (tightens) at least one new turn of wire onto the core for every complete circulation of the loops around the guide. Two or more wires can be wound onto a core at the same time with the method according to the invention.
In a method of winding wire having a free end onto a core having a central opening including the steps of forming the wire into a coil having a plurality of generally circular loops through the core's opening, each loop being formed in sequence about the coil's central axis radially inwardly of the loops previously formed so the coil has a thickness along this axis of less than two wire diameters and thereafter winding the wire onto the core by circulating the loops through the core's opening about the coil's axis, the improvement comprising;
A method of winding turns of wire onto a core wherein the improvement comprises the steps of:
A method of providing a core with a bifilar wire winding in which each succeeding turn on the core is a different wire comprising the steps of forming two lengths of wire into a single radial layer of double loops comprising a circular coil through the aperture of the core and winding the coil into a plurality of turns on the core wherein the step of forming the coil through the core's aperture comprises simultaneously feeding two different wires side by side along their lengths from a position inwardly of the radial boundary of a circular channel and out of the plane of the channel, into and along the channel until the first double wire loop is formed and thereafter advancing both wires further around the channel forcing their noses between the loop just formed and the radial boundary causing each successive double loop to form radially inwardly of its predecessor.
