Saw blade for a frame saw having teeth with reinforced edges

Claim 1

A saw blade for a frame saw comprising a planar blade body provided with a multiplicity of spaced apart teeth forwardly overhanging teeth-spacing recesses in the direction of cutting movement of the blade, and respective elongated reinforcement portions extending all along the crests of each of said teeth of a thickness in excess of the thickness of said body and disposed symmetrically with respect to the faces thereof, each of said reinforcement portions comprising: a front planar flank inclined rearwardly away from an apex of the reinforcement portion and at an acute angle to a plane perpendicular to said body and said direction of cutting movement; a planar top flank defining an acute angle with said front flank at said apex and inclined rearwardly at an acute angle away from a plane parallel to said cutting direction but perpendicular to said body; and a pair of longitudinally extending planar lateral flanks of uniform width over the entire length of the reinforcement portion and defining sharp edges at angles of 90* with said top flank, said lateral flanks converging toward one another symmetrically rearwardly and each having a limiting edge spaced from the edge defined with said top flank and parallel thereto.
