Abstract

A method and apparatus for removing tread from tires preparatory to retreading of the tires in which a tire is mounted on a support and inflated and rotated on the axis of the tire. The tread is removed from the tire by a cutter disc which has cutting elements mounted thereon in an annular path with the annular path being presented to the periphery of the tire. The cutter disc and tire are moved relatively to cause the annular path of the cutter disc in which the cutting elements are mounted to traverse the tire from side to side and in a single pass across the tire the tread is removed therefrom. The relative movements between the tire and the cutter disc are under the control of a cam so that the proper contour is imparted to the periphery of the tire. The cutting elements mounted in the aforesaid annular path of the cutter disc are in the from of sharp edged discs of hard material which take clean chips from the tread of the tire thereby avoiding heating of the tire or the cutting elements and, likewise, eliminating smoke and dust that normally accompanies the removal of tread material by the use of a cutting device employing rasp elements therein.
