Abstract
Metal foil base material placed on lower blade is first restricted under pressure by lower blade and pad and then cut by a shearing action based on an engagement of lower blade side cutting edge and upper blade side cutting edge. Resin face sheets are fixed to the top surface of lower blade and the pressing surface of pad, the face sheets having a larger friction coefficient than that of these surfaces. By frictional forces imparted by face sheets, metal foil base material is prevented from being dragged and moved by the pressing force of the upper blade prior to cutting. Consequently, the occurrence of 'burr', 'roll-up', and so forth is eliminated thereby ensuring a good cutting quality.
