Abstract
An apparatus for removing the bead wires from a scrap tire having a pair of overlapping and counterrotating shearing members and a movable carriage. The carriage includes a plurality of rolls positioned to fit within the inside diameter of a tire. One of these rolls is a tensioning roll that is movable so as to stretch the tire and elongate the bead wires. This elongation crowds the bead wires against a crowding bar. The crowding bar and a pair of compression rollers are mounted to a rod which is moved downwardly when the carriage is advanced toward the shearing members, said compression rollers being positioned to apply compression force to the side wall of the tire as the rollers descend. The compression force aligns the bead wires with a bead guide roll so that the crowding bar may be pivoted away from the subsequent shearing action, the bead wires then being crowded against the bead guide roll. At the same time a spring biased lower compression roller is cammed upward to apply compression force to the lower side wall. The carriage is advanced until the shearing members have made a first tire shear that is at least closely tangential to the bead wire against the bead guide roll. When the pinch point of the shearing members is proximate the bead wires, forward movement of the carriage is stopped. However, the tire is caused to be rotated about its axis by the shearing members to produce a second shear that is substantially concentric with the bead wires, the first and second shears being a single continuous motion.
