Patent ID: 8245615

Claim:
A tire tread skiving machine comprising: an elongated frame having two spaced ends, an elongated cutting platen extending transversely across said frame between said two ends, an infeed conveyor mounted to the frame and extending from one end of the frame to said cutting platen, said infeed conveyor adapted to move an extrusion to said cutting platen, an outfeed conveyor mounted to the frame and extending from said cutting platen to the other end of the frame, said outfeed conveyor adapted to move a tire tread cut from the extrusion away from said cutting platen, a rail assembly mounted to said frame so that said rail assembly overlies said cutting platen, a carriage movably mounted to said rail assembly in a direction parallel to said cutting platen, a slide linearly movably mounted to said carriage in a direction transverse to the axis of the cutting platen and also transverse relative to the direction of movement of said carriage, a motor mounted to said slide and movable therewith, a skiving blade rotatably driven by said motor, an actuator connected to said slide and operable to move said slide together with said skiving knife between a retracted position in which said skiving knife is spaced outwardly from said cutting platen and an operative position in which an outer periphery of said skiving knife is positioned within a well extending along said cutting platen, wherein said rail assembly is pivotally mounted to said frame so that, by varying the pivotal position of said rail assembly, the angle of cut of said skiving blade through the extrusion is likewise varied.
