Date Sep. 4, 1997Cutters are disclosed including a pair of cutting blade holders and a pair of cutting blades mounted for movement in a cutting direction with respect to each other, at least one of the blade holders comprising a sprung holder. The apparatus includes a pair of material-weakening channel zones associated with one of the cutting blades defining a supporting zone for that cutting blade, each of the pair of material-weakening channel zones including first and second material-weakening channels extending from the upper surface of the sprung holder and across the entire width of the sprung holder, and the second material-weakening channel juxtaposed with the first material weakening channel and extending from the lower surface of the sprung holder and across the entire width of the sprung holder, thereby creating material bridges between the two material-weakening channels creating an elongation zone, and an adjustment screw positioned in one of the material-weakening channels whereby the material bridges may be displaced in order to displace the supporting zone in an adjustment zone perpendicular to the cutting direction.</p> |
