Abstract: A method and apparatus 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 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 and apparatus according to the invention.

Abstract translation: 一种用于将线束缠绕在环形芯上的方法和装置，其中一段电线沿着在圆弧形引导件中的径向向内的通道进给以形成环。 当导线的前端完成这个循环时，它拥抱通道的径向边界，以在导线继续进行时在第一个内部形成第二个回路。 在通道的径向边界处提供间隙，用于在该间隙中具有芯的中心孔以接收芯，使得每个环形成在该环中通过芯的线。 通道的上边界和下边界是间隔开的，以便将环保持在围绕引导件并通过芯的单个同心层中。 当进给足够的电线时，停止进给，但环绕引导件的环的移动继续，并将至少一匝新的电线卷绕（拧紧）到芯上，以使环绕引导件完全循环。 可以使用根据本发明的方法和装置同时将两个或更多个线缠绕在芯上。
