ABSTRACT:
The present tire cutting machine can rotatably support a wheel mounted and inflated tire with the tread thereof facing one or the other of a groove cutter, and a rotatable siping blade assembled with a feeler. The tire can be driven from the wheel for cutting circumferential grooves, or can be driven by the siping cutter and/or a lead screw when siping. When the feeler and siping blade engage the tire, the feeler maintains the siping blade in proper relation to the tire tread for said siping blade to cut and move around the tire tread to effect minute lateral cuts or sipes in a section of the tire tread.
