WINDING DEVICE Russian patent published in 2017 - IPC B29D30/48 

FIELD: machine building.

SUBSTANCE: invention relates to winding device. Technical result is achieved by winding device having base plate, which is rotated by means of rotary shaft, plurality of segments arranged in annular zone corresponding to base plate outer circumference. At that, every segment has shape corresponding to one of forms obtained by annular zone dividing into plurality of sections along base plate circumference. At that, each of segments is supported by base plate, each is in movable way in base plate radial direction. Manipulation shaft, which is rotated by means of handle, and conversion mechanism arranged between manipulation shaft and each segment. At that, conversion mechanism converts manipulation shaft rotation into corresponding segment movement in base plate radial direction. At that, conversion mechanism includes: first gear wheel, supported by base plate in rotary manner relative to rotating shaft, second gear wheel attached to manipulation shaft so, that to engage with first gear wheel, plurality of threaded shafts supported by base plate, plurality of third gear wheels attached to threaded shafts so, that to engage with first gear wheel, and plurality of movable elements, which are directed by plurality of guide sections, which are formed on base plate, to pass in base plate radial direction. Each of threaded sections includes internal threaded section, screwed in to corresponding threaded shaft, and each of segments is supported by one of movable elements. At that, when base plate rotates, wire is wound on segments outer circumference, which rotate integrally with base plate, thereby forming bead ring.

EFFECT: technical result is simplification of rings with different diameters winding.
