ABSTRACT:
A tire is placed upon an infeed support which initiates movement of a spindle to extend longitudinally through the tire, then expand radially to engage the tire beads and then retract longitudinally to clamp the beads together. One of a pair of power driven rolls having roughened, wear resistant surfaces, then is moved toward the fixed roll of a pair to grip the tire between them and rotate the tire and spindle assembly. The spindle and drive roll assembly, together with the rotating tire, then is moved by a common support carriage toward a rotary flywheel type cutter assembly which operates on the tire in the radial direction inward from the tread area to an area closely adjacent the metal beads, reducing the tire to small pieces. An air fan is integrated with the flywheel of the cutter assembly to minimize heating of the flywheel and cutter mechanism. A metal sensor on the infeed support prevents operation of the apparatus if the tire contains steel belts.
