During the process of manufacturing tires, vulcanized tires are classified by the utilization of radiations into the white tire having a white rubber compound layer, or a white ribbon, and the black tire having no such white ribbon, while those tires are classified according to the external dimensions such as an inside diameter. More specifically, a radiation source provided on the side of one wallside of a tire emits radiations to the tire at a predetermined angle of inclination, while a radiation detector provided on the side of the other wallside of the tire detects the intensity of radiations which have passed through the tire, whereby the classification of tires is carried out according to the comparison of two outputs which the radiation detector produces at two predetermined relative positions of the tire and the radiation source.

Method and device for classifying tires

Rubber cloth splicing apparatus broadly comprising a forward vibrating conveyor, a butt-splicer, a backward vibrating conveyor, and a take-up conveyor. Each piece of rubber cloth is fed by the forward vibrating conveyor onto the rear table of the butt-splicer and is clamped in position thereon, whereas the precedingly spliced rubber cloth piece is fed backwardly by the backward vibrating conveyor onto the front table of the butt-splicer and is similarly clamped in position thereon. The two rubber cloth pieces are joined end to end without overlap as the rear table is forced into abutting contact with the front table. The take-up conveyor carries the spliced pieces of rubber cloth away from the butt-splicer via the backward vibrating conveyor by indexed movement.
