Patent number: 3985310Abstract: 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.Type: GrantFiled: October 7, 1974Date of Patent: October 12, 1976Assignee: Pulse Engineering Inc.Inventors: Bryan Kent, Duane Kent
