DEVICE FOR FABRICATION OF BEAD RING Russian patent published in 2016 - IPC B21F37/00 B29D30/48 

FIELD: machine building.

SUBSTANCE: present invention relates to machine building and can be used for production of tire bead rings by means of winding a wire around the outer surface of a solid of revolution. Device comprises a solid of revolution for winding a wire, divided to form a plurality of separate elements, which expand and contract in the radial direction by means of an expansion and compression mechanism, and a clamping mechanism which places and removes the end of a wire with reference to expansion and compression of the separated elements. Invention covers the design of the said elements of the device.

EFFECT: reliable winding of a wire with formation of a bead ring using a simplified design of the device.
