Claims24
An apparatus for cutting a tire groove in the road gripping surface of a tire comprising:
- stabilizer means for guiding a cutting head member in a cutting direction at a substantially constant angle along the road gripping surface of the tire;
- the stabilizer means having a substantially planar surface for slidably engaging the road gripping surface of the tire;
- the substantially planar surface having a forward edge and a rearward edge;
- the cutting head member having a blade for cutting through the tire in the cutting direction;
- the blade having a cutting edge and a back edge;
- and
- the forward edge being positioned in front of a reference line normal to the cutting direction passing through the cutting edge of the blade, the rearward edge being positioned substantially even with a reference line normal to the cutting direction passing through the back edge of the blade.
