Title:
BEAD RING WINDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/145192
Kind Code:
A1
Abstract:
A bead ring winding device is provided with a traverse mechanism (12) comprising: a rotating body (21); a traverse roller (35); and an air cylinder (44). The rotating body (21) is provided so as to be capable of rotating about a rotation shaft and has an outer peripheral surface on which an annular winding section (23) for winding a wire is formed. The traverse roller (35) engages with the wire (W) wound by the winding section (23) and arranges the windings of the wire (W) side by side in the direction of extension of the rotation shaft. The air cylinder (44) applies pressing force to the traverse roller (35) in the direction in which the traverse roller (35) presses the wire (W). The bottom surface of the winding section (23) is formed in a tapered shape. The traverse mechanism (12) is provided with a cam member (63) having a sloped cam surface (63a). The sloped cam surface (63a) guides the traverse roller (35) so that the traverse roller (35) traverses parallel to the tapered surface (24a) of the winding section (23).
