Patent ID: 8784946

Claim:
A method comprising: feeding a continuous core of a print cartridge cleaning blade along a path, said path passing, in the following order, firstly through a coating bath, secondly by a curing station, thirdly through a cutter, and fourthly to a finisher station, said core being selected to comprise a rectangular shape having a top, a bottom, sides, and ends, said core comprising square corners located where said sides of said rectangular shape meet said top and said bottom, said rectangular shape having a length greater in size than a thickness and a height, said height being greater in size than said thickness, said top and said bottom being rectangular planes defined by said thickness and said length, said sides being rectangular planes defined by said height and said length, and said ends being rectangular planes defined by said height and said thickness; coating portions of said continuous core that are in said coating bath with an outer covering, said outer covering consisting of polymer materials, said outer covering being selected to form four square blade edges where said outer covering covers said square corners, and an elastic modulus or said core being at least five times that or said outer covering; for portions of said continuous core that are adjacent said curing station, curing said outer covering of said continuous core; for portions of said continuous core that are in said cutter, cutting said continuous core into lengths; and for portions of said lengths of said continuous core that are adjacent said finishing station, finishing said outer covering of said predetermined lengths of said continuous core to produce a finished print cartridge cleaning blade, said four square blade edges comprising four distinct blade edges that contact surfaces being cleaned permitting said finished print cartridge cleaning blade to be flipped or rotated to utilize a new blade edge.
