Abstract: A bead forming apparatus including: a rotatable drum having a plurality of divided bodies dividedly arranged along a circumference and being adapted to be wrapped therearound with a belt-shaped bead filler having a short base and two other long sides in an annular shape; a plurality of erection arms provided along the circumference and swingably supported by the divided bodies of the rotatable drum so as to erect the bead filler by swinging the erection arms; and a swing device for swinging the erection arms; and a plurality of slide members provided as contact portions of the erection arms that come into contact with the bead filler so that the bead filler can be radially slidable relative to the erection arms.

Abstract: A press-up member presses a movable member upward, thus raising a pressing member. A support block is moved forward by means of the press-up member and a moved member. Due to the cam action brought about by such movement, the pressing member is arranged above a filler on a balloon of a molding drum. Then, the press-up member is lowered to press a distal end section of the filler onto the balloon. In this state, the molding drum is rotated to mold the filler in an annular shape. The pressing member is then separated from the filler and the pressing member is arranged at a standby position outside the molding drum. The press-up member and the moved member are separable from each other and, in the separated state, the molding drum is independently rotatable.

Abstract: A festoon device includes a frame, which extends vertically, an upper pulley, which is rotationally supported by an upper part of the frame, and a lower pulley, which is rotationally supported by the frame below the upper pulley and is selectively moved up and down. The frame rotationally supports two auxiliary pulleys, which are arranged at a position closer to the frame than the upper pulley and the lower pulley. The festoon device is configured such that a wire is looped about the upper pulley and the lower pulley after being looped about the auxiliary pulleys.

Abstract: A winding machine includes a first rotary body to be rotated by a rotary shaft, and a second rotary body to rotate on the same axis as the first rotary body and at the same speed as the first rotary body. The winding machine further includes a cylinder to open and close the first and second rotary bodies relative to each other. An outer circumferential surface of at least one of the first and second rotary bodies in a part where the first and second rotary bodies join is provided with a groove in which a bead ring is to be formed by winding a wire.

Abstract: A winding device is provided that includes a base plate that is rotated by a rotary shaft and segments. With rotation of the base plate, a wire is wound on the outer circumference of the segments, which rotate integrally with the base plate, to form a bead ring. The winding device includes an manipulation shaft that is rotated by a handle, and conversion mechanisms that are provided between the manipulation shaft and each of the segments The conversion mechanisms transmit and convert rotation of the manipulation shaft to movement of each segment in the radial direction of the base plate.

Abstract: A winding apparatus winds a wire around the circumference of a circular former and lays out the wire in an arrangement of columns and rows to form a bead ring. A roller for pressing a wire positioned on the circumference of the former is located on an apparatus frame and movable in a direction along the columns of the wire and a direction along the rows of the wire. A circular cam having cam surfaces is supported by a camshaft that rotates in synchronism with rotation of the former. A cam follower is engaged with the cam surfaces of the cam and moved integrally with the roller in the direction along the columns of the wire and the direction along the rows of the wire. Thus, the cam surfaces act to move the roller in the direction along the columns of the wire.

Abstract: A winding unit is formed in an annular pattern along the outer circumferential surface of a rotary body rotatable about a shaft. The winding unit has multiple alignment grooves in which a wire is wound and turns of the wire are aligned. The winding unit is provided with an ungrooved part formed to straddle the alignment grooves.

Abstract: A bead ring winding device includes a traverse mechanism (12) formed of a rotary body (21), a traverse roller (35), and an air cylinder (44). The rotary body (21) is rotatable about a rotary shaft and has an outer circumferential surface provided with an annular winding unit (23) for wire winding. The traverse roller (35) makes a fit to a wire (W) wound by the winding unit (23) to align turns of the wire (W) in juxtaposition in a direction in which the rotary shaft extends. The air cylinder (44) applies biasing force to the traverse roller (35) in a direction in which the wire (W) is pressed. The winding unit (23) has a bottom surface of a tapered shape. The traverse mechanism (12) includes a cam member (63) having a sloping cam surface (63a). The sloping cam surface (63a) guides the traverse roller (35) such that the traverse roller (35) traverses parallel to a tapered surface (24a) of the winding unit (23).
