ABSTRACT:
A device for removing the beads from scrap tires is disclosed and includes a pair of chain-and-sprocket driven spindles which are relatively expandable to engage the inner periphery of a tire and drive the tire in a somewhat rotary manner past a pair of cutting knives which sever the beads from the rest of the tire. After severing, the spindles are retracted toward one another to allow removal of the remaining tire casing and the two severed beads, and the placement of another scrap tire over the spindles. In a preferred form, one spindle pivots about the axis of its own driving sprocket so that the tension in the chain entrained about that driving sprocket and the driven sprocket coaxial with that spindle remains constant. A unique tire casing support near the cutting knives is also disclosed.
