摘要:
A tire testing apparatus allows attachment and detachment of a rim assembly in which first and second rims are integrated and performs testing of a tire attached to the rim assembly. The tire testing apparatus includes a first attaching part; a second attaching part; a rotating part that rotates the first attaching part around a reference axis orthogonal to the first reference surface of the first rim attached to the first attaching part; a fixing part that fixes the first attaching part and the second attaching part to each other and is capable of releasing the fixation; an attaching portion moving part that adjusts the distance in a direction along the reference axis between the first attaching part and the second attaching part; and a rotation regulating part that regulates rotation of the second attaching part around the reference axis.

A belt-shaped member cut into a predetermined length is fed from a feeding devices to a tire forming drum and is wound on its cylindrical peripheral surface. Center portions of the opposite ends of the belt-shaped member are pushed to be joined to each other and the side portions of at least one of the opposite ends of the belt-shaped member are held by upper and lower holding pawls. Such holding pawls are swung along an arcuate path so that both side portions of the opposite ends of the belt-shaped member are drawn near each other to abut against each other. The abutting end portions are pushed toward the peripheral surface of the drum by pushing devices for joining them together.

A method and apparatus are provided for positioning sheets of material on a belt feeder for transporting the material through a cutter toward a tire-processing apparatus. The material has a front-edge portion which is centered by using edge-position control, and side portions which are centered by using center-position control. Also, the material, as cut, will have a rear-edge portion, the centering position of which is controlled by edge-position control.

An object of the present invention is to provide a tread centering device which automatically detects the position of tread center and holds it in a straight form even when the center of tread is not positioned in a straight form. The device mainly comprises a plurality of detectors for detecting a groove for centering the tread, a holding plate which is inserted into the detected groove, and a mechanism which moves said holding plate transversely to align said groove in a straight form.
