ABSTRACT:
Tire grooving knives (122) are moved on a frame (28) into a grooving position adjacent the curved tire tread surface (130) of an inflated tire (12) of a predetermined diameter mounted for rotation on a supporting stand (14). The knives (122) are then individually moved by separate actuating assemblies (60) into engagement with the tire tread surface (130) so that as the (12) tire is rotated circumferential (128,156,160) grooves will be cut. The (122) knives and actuating assemblies (60) are adjustable to cut grooves (128,156,160) having sides (158) perpendicular to the tread surface (130) and to cut grooves (128,156,160) in different diameter tires. The knives (122,122',122") may also be positioned on the frame (28) at circumferentially spaced locations (172,174,176) around the tire tread surface (130) to provide space for the actuating assemblies (60) to cut closely spaced grooves (128,156,160).
