ABSTRACT:
A tire cutting machine can rotatably support a wheel mounted and inflated tire with the tread thereof facing one or the other, or both, of a groove cutter, and a rotatable siping blade assembled with a lead screw. The tire can be driven by a spiked roller for cutting circumferential grooves, or can be driven by the siping cutter and a lead screw when siping. The siping cutter can be shifted axially of the tire by a motor-driven feed screw with adjustable automatic shut-off.
