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.
