Scrap tire processing apparatus

摘要

An apparatus for processing a scrap rubber tire carcass having a circumferential crown and a pair of sidewalls extending generally radially inwardly from and generally perpendicular to the crown, each of the sidewalls having an inner circumferential edge. Included are tire holding apparatus for holding the tire carcass while cutter blades cut the held tire carcass through from the inner circumferential edge to the crown substantially along a single radius at one place. Pinch rollers advance the cut tire carcass longitudinally in a direction generally tangent to the circumference of the drown while a spreading channel receives the cut end and on a continuous basis flattens the sidewalls such that the sidewalls and crown lie substantially in a common plane. The flattened carcass is advanced by additional pinch rollers into a granulator which chops the received tire carcass to particles. Rotating cutter blades shear off the beads from the sidewalls in scissors fashion prior to flattening of the sidewalls and slitter rolls having interdigitated cutting disks slit the flattened tire longitudinally prior to entry thereof into the granulator.
