Saw blades and saw assemblies
First Claim
1. A saw blade assembly comprising a laminated structure including two outer parallel strips each having formed along one edge thereof a row of spaced saw teeth extending longitudinally of the assembly, such that the roots of the teeth in the row on one of said outer strips are laterally spaced from the roots of the teeth in the row on the other of said outer strips, and an inner spacer strip extending longitudinally between said two outer strips and permanently affixed on its opposite sides to said two outer strips such that the thickness of said inner spacer strip determines said lateral spacing, said inner spacer strip extending to but not beyond the base of the roots of said row of teeth on said two outer strips.

Abstract
A saw blade assembly comprises a laminated structure of three side-by-side parallel strips, one two or all of which may have spaced teeth formed along one edge. Where only one strip has teeth, it is sandwiched between the two other strips and the teeth are of triangular shape when seen in plan and are bevelled on both edges to produce pointed tooth tips. Where two strips have teeth, the strips are arranged one on each side of a center strip. Again, the teeth are of triangular shape when seen in side elevation and are contoured to form pointed tips. The roots of the teeth on one strip are spaced laterally from the roots of the teeth on the other strip because of the presence of the center strip. In another form, each strip has teeth along one edge, the assembly thereby providing three parallel, side-by-side rows of teeth. The teeth are of triangular shape when seen in side elevation and are contoured to form pointed tips.
