<p>A cleaning blade holder that has a top portion (90), and bottom portion (95) which contains a groove (40) into which a protruding rib (65) on the back side surface of the blade (60) fit. An alternative bottom portion (94) has a plurality of nodules (100) that interconnect with apertures in corresponding positions along the length of the blade body. The blade holder holds the blade body in a horizontal position allowing the edges on either side of the blade body to extend from the holder. Each side of the blade body provides two edges (60a,60b,60c,60d). Rotation of the blade holder produces a new cleaning edge. Two other cleaning edges are produced by reversing the blade body in the holder and rotating the blade holder again between positions one and two. <IMAGE> <IMAGE></p> |
