Title:
GROOVED INCISOR SHREDDER CUTTING BLADE SET AND METHOD
Document Type and Number:
WIPO Patent Application WO/2013/062631
Kind Code:
A3
Abstract:
A grooved incisor blade set for paper shredders is disclosed. A blade includes a crown, a groove juxtaposed with the crown, and a center hole for a cutting arbor, where the crown and the groove define a relief channel. A stair-shaped, U-shaped or V-shaped blade assembly is described. In one embodiment, a notched grooved incisor blade having notches proximate to the central hole comes in contact with a mating grooved incisor blade also having a central hole. Force is applied to the mating blade to displace some of the body of the mating blade into the notches, affixing the blades together. A method for forming shredder cutting blades includes providing a strip of metal, forming a crown in the strip of metal, forming a relief groove juxtaposed to the crown in the strip of metal, thereby forming a relief channel, and trimming the grooved incisor blade of excess metal.
