Abstract: 1501987 Winding annular cores KOBE STEEL Ltd 9 April 1975 [10 April 1974 11 July 1974 31 July 1974 17 Sept 1974 (2) 25 Sept 1974 18 Nov 1974] 14556/75 Heading B8G Apparatus for winding wire around an annular core wire comprises a carrying table for mounting an annular core wire in a first wire winding position; a mechanism for moving the core wire in a peripheral direction; a rotary body mounted for rotation about an axis adjacent the periphery of the core wire so that at least part of the rotary body passes through the annulus; a drum support means rotatably and releasably mounted on said part of said rotary body; and a wire for storing winding wire rotatably mounted on the drum support means; the rotary body including a slit extending from its periphery to its rotation axis, and the carrying table being mounted for movement through the slit to move the core wire to a second position outside the rotary body so that the core wire may be loaded on to and unloaded from the table. The wire core need not be of circular shape. The apparatus comprises, Fig. 6, turntable 52 indexed to locate horizontal annular wire core 1 in a winding position in which, initially, core 1 is located in gap 55 in rotatable member 5. Member 57 releasably carried by turntable 52 is releasably attached to member 5 within a hole in the member 5. Member 57 rotatably carries member 20, bearing reel 22 of winding wire 2, and wire guide 38. When wire 2 has been secured to core 1, member 5 is rotated to pass through annular core 1 so that wire 2 is wrapped about the wire of core 2 which is itself rotated in a peripheral direction on the stationary turntable. Simultaneously, member 20 is rotated in member 57 to rotate the reel to prevent twisting of wire 2. Member 20 is rotated by gears on member 5 engaging an internally-toothed ring on frame 3, the gears driving member 20 via variable gear 27 adjusted by motor 32. Reel 22 is braked by band 36. Member 5 is clamped in its Fig. 6 position by clamp arms 104, 105 actuated after device 109 has counted the rotations of member 5. The turntable comprises, Fig. 8, three stations x, y, z indexable between loading station A, winding station B and unloading station C. Each station x, y, z comprises a hole 70 connecting with a gap in the turntable periphery, rollers 75 to movably support annular core wire 1, a groove around the hole edge to slidingly guide bent end 2<SP>1</SP> of winding wire 2, and clamp 74 to releasably secure a member 57 carrying a rotatable member 20, reel 22 and guide 38. The turntable is rotated by a rack-and-pinion drive via a one-way clutch. Means 12 movably secured on frame 3 serves to move core 1 on rollers 75. Stations A and C may be combined, or station A may comprise two stations. Adaptors may be fitted in holes 70 to receive wire cores of differing size. Means for loading and unloading the turntable may be located on the turntable. In a known apparatus, Fig. 1, annular core wire 1 is located initially in a slot 9 in rotatable member 5 which permanently carries rotatable member 20 in a hole, member 20 carrying reel 22 and guide 38.
