Abstract
A segment-shaped blade is provided for use in a rotatable cylindrical tool for machining elastic material, particularly pneumatic rubber tires for vehicles. The blade comprises pointed triangular teeth, which are provided on a convex periphery and are staggered and divided by radial cuts. Each radial cut extends only as far as to the root of the tooth concerned and each triangular tooth is divided by one or more radial cuts into at least two triangular prongs which have pointed tips that are much more slender than the pointed tip of the original tooth.
Claims4
A segment-shaped blade for use in a cylindrical tool for machining elastic material by rotating the tool in a direction of rotation, the blade extending in a plane and having a convex periphery extending in a curved plane perpendicular to the plane of the blade, which comprises a plurality of triangular teeth arranged along the periphery between peripheral recesses, each triangular tooth having a root in another curved plane inwardly spaced from, and substantially parallel to, the curved plane wherein the periphery of the blade extends, and each tooth being divided by a substantially radial cut extending no farther than the root of the tooth into prongs having pointed tips, at least alternating ones of the prongs being bent to a side of the plane of the blade and the pointed tips of all prongs lying in the curved plane wherein the periphery of the blade extends and laterally staggered from each other in relation to the plane of the blade.
