Method of making chisel-type cutter link

Abstract From the Canadian patent

Abstract of the Disclosure, A method of cold-forming a substantially right-angle final bend in a chisel-type saw-chain cutter link. The method involves the progressive, staged shifting of a bend and of the, inside and outside corners therein in a cutter blank from a, starting, greater-than-right-angle bend line toward an adjacent substantially parallel, final substantially right-angle bend line. Subsequent to the making of an initial bend in a blank the making of later shifted bends is accompanied by the flowing of material in the blank toward the region of the later-produced bends.
