  • Patent number: 4169373
    Abstract: A tire bead inspection machine comprises a base on which a tire may be mounted for inspection. A frame is mounted on the base from which a first roller is cantilevered with a generally vertical axis and a pair of rollers on either side of the first roller are cantilevered in a direction transverse to the first roller, that is with generally horizontal axes. The frame is moveable on the base in a fashion to insert the first roller into the tire and force the bead outward, and at the same time swing the pair of rollers toward the vertical against their spring mountings in such a way that they exert force against the sidewall of the tire. In this fashion, the bead is grasped somewhat scissor fashion between the first roller and the pair of rollers. The first roller exerts a force against the inner part of the bead and the pair of rollers resist the force exerted by the first roller.
