Abstract
A tire rasp blade for use in a tire buffing machine having a rotating hub. A set of rasp blades is arranged in a plurality of circumferential rows. Each of the blades has a non-planar elongated body with generally planar portions, and an arcuate working edge having teeth which extend in a direction generally parallel to the direction of hub rotation. The working edge includes two elliptical-shaped segments.

A tire rasp blade for use in a tire buffing machine which includes a rotating hub, comprising:
- an elongated, generally arcuate and nonplanar body having two generally planar end portions each having first and second opposing sides, said generally planar end portions intersecting in a vertex positioned at a mid-portion of said body;
- and
- a working edge having two curved surfaces, each of said curved surfaces defining a portion of an ellipse having unequal major and minor axes and providing an effectively circular working edge when said blade is mounted to an rotated on said hub.
A tire rasp blade for use in a tire buffing machine, comprising:
- a rotating hub;
- an elongated, generally arcuate and nonplanar body having two generally planar end portions intersecting in a vertex positioned at a mid-portion of said body, the angle each said planar end portion makes with a plane normally intersecting the rotating hub being approximately 4.degree.;
- and
- a working edge having two curved surfaces, each of said curved surfaces defining a portion of an ellipse having unequal major and minor axes and providing an effectively circular working edge.
A tire rasp blade for use in a tire buffing machine, comprising:
- a rotating hub;
- an elongated, generally arcuate and nonplanar body having two generally planar end portions intersecting in a vertex positioned at a mid-portion of said body, the angle each said planar end portion makes with a plane normally intersecting the rotating hub being approximately 3.degree.;
- and
- a working edge having two curved surfaces, each of said curved surfaces defining a portion of an ellipse having unequal major and minor axes and providing an effectively circular working edge.
