ABSTRACT:
A method for manufacturing a double-edge peeling knife blade which includes the steps of providing a strip of steel which is sharpened along each edge to form blade portions, punching notches out of the strip steel to leave blade blanks interconnected by a connecting web, punching out a central region to form an aperture having a width greater than half the width of the strip of steel and a length less than the length of the blade blank to leave bridging sections interconnecting the blade portions, then bending the blade portions at right angles to the blade blank, bending the bent blade portions a second time to overlap a portion of the aperture, parting the connecting web and forming the blank into an arcuate configuration. Preferably, this strip is sequentially processed as it is moved in a step-like manner through the processing dies and punches.
