摘要： A bead ring bonding cord winding apparatus includes a feed roller that feeds a bead ring, which is formed by winding a wire a multiple number of times, in a circumferential direction of the bead ring, a gripping member that grips an initiating end of a bonding cord, and a rotation member that rotates past an inner side and an outer side of the bead ring while holding the bonding cord. In the bead ring bonding cord winding apparatus, while the bead ring is fed in the circumferential direction, the rotation member is rotated past the inner side and the outer side of the bead ring to spirally wind the bonding cord around the bead ring. The gripping member is located at an upstream side of the rotation member in the feeding direction of the bead ring.

摘要： A bladder is made to be expandable and contractible at a vulcanization position within a lower mold assembly and to be expandable and contractible also at a tire delivery position which is spaced a predetermined distance from the vulcanization position along a center axis of the lower mold assembly. With a centering shaft passing through an upper mold, the bladder and the lower mold assembly, a green tire loaded into the tire delivery position is held by the bladder by expanding the bladder and is loaded by the bladder into the lower mold assembly. After a vulcanization processing, the bladder removes the vulcanized tire from the vulcanization position to the delivery position, and after the centering shaft is drawn out from the lower mold assembly and the bladder, the bladder is contracted at the delivery position to make it possible to release the vulcanized tire from the bladder. Thus, the green tire is supported evenly at the whole area on the internal surface thereof by the bladder which is expanded to a predetermined shape at the stage of receiving the green tire at the delivery position. Thus, the forming shape of the green tire can be fixed accurately, so that the tire shape after the vulcanization processing can be maintained accurately.

摘要翻译： 使囊状物在下模具组件内的硫化位置处可膨胀和收缩，并且还可以在沿着下模具组件的中心轴线与硫化位置隔开预定距离的轮胎输送位置处可膨胀和收缩。 通过穿过上模具的定心轴，气囊和下模具组件，装载到轮胎输送位置的生胎通过膨胀气囊由气囊保持，并且由气囊装载到下模具组件中。 在硫化处理之后，气囊将硫化轮胎从硫化位置移除到输送位置，并且在定心轴从下模具组件和气囊引出之后，气囊在输送位置收缩， 从膀胱释放硫化轮胎。 因此，通过在输送位置处接收生胎的阶段将生胎膨胀成规定形状的囊状物将其均匀地支承在其内表面的整个区域上。 因此，可以精确地固定生胎的形状，从而可以准确地保持硫化处理后的轮胎形状。

摘要： A rotary body is divided into four to form multiple partitioned members. A chuck mechanism includes an expanding and contracting mechanism that expands and contracts each partitioned member in a radial direction of the rotary body. The chuck mechanism mounts and dismounts the beginning of a wire in an interlocked relationship with expansion and contraction of each partitioned member. The expanding and contracting mechanism includes a guide member that moves each partitioned member back and forth in the radial direction, and a cam member that moves each partitioned member between a large-diameter position and a small-diameter position. The chuck mechanism includes a chuck arm, a coil spring that biases the chuck arm in a direction in which the chuck arm is closed, an arm member that opens and closes the chuck arm, and a cam actuator that makes the arm member pivot.

摘要： In a bead manufacturing method and bead manufacturing device, a former rotatably supported on a support base and pivotably holds opposite end portions of a plurality of elastically deformable spring members arranged on an outer circumference thereof with gaps in a circumferential direction for annularly winding a bead filler around the spring members, an actuation mechanism is provided for curving the spring members in the radial directions of the former, and a bead core holding portion is arranged at one end side of the former for holding a bead core. When the spring members are elastically deformed outward in the radial directions of the former to a semicircular shape, the bead filler annularly wound around the spring members are raised up to fixedly fit a short bottom side thereof on the outer circumference of the bead core held at one end side of the former.
