Abstract
The present invention discloses a process to manufacture toothed blades such as saw blades. The blades are made from strip stock that has spaced notches along at least one edge defining tooth blanks therebetween. The notches may be any convenient shape and made at any angle such as 45° to the edge. That angle becomes the rake or front incline angle of the tooth. The teeth are then formed by pinching the metal of the tooth blank at a particular location near the notch so as to displace the leading or rake edge of the notch below the original edge.
The pinching is done either in a batch process of blade by blade on punch and anvil, or in a continuous process between pinching rollers having peripheral punches rotating in timed sequence with the notched strip passing therebetween. A
single step punch and dimple method is also disclosed.
The pinching is done either in a batch process of blade by blade on punch and anvil, or in a continuous process between pinching rollers having peripheral punches rotating in timed sequence with the notched strip passing therebetween. A
single step punch and dimple method is also disclosed.
