APPARATUS AND METHOD FOR MAKING SAW BLADES. ABSTRACT OF THE DISCLOSURE An apparatus and method of making a continuous saw blade having stepped saw segments whereby the cutting teeth in each seg- ment define a cutting edge which is inclined relative to a back edge so that the respective teeth are rendered self-feeding during a cutting operation. The apparatus includes a moveable carriage having a pair of clamps mounted thereon for gripping a saw blade to be formed therebetween. The clamps are formed to effect the heating of the saw blade clamped therebetween, and operated to impart a lateral offset in the blade as the blade is being formed. The back edge of the respective offset segments are then trimmed to define a back edge which is coincidental for the length of the saw blade and the cutting edge inclined to the back edge in each segment so as to render the cutting teeth of each segment self- feeding during a cutting operation.
