    摘要： A paper cutting machine is provided for cutting a plurality of sheets of paper stacked one upon another on a table, including a paper support (2) that moves down from above along longitudinal beams (19, 19) and a cutter (3) that moves up from below in an oblique direction. The paper support (2) has a rest (18) for receiving a cutting edge of the cutter. The rest (18) is moved in a predetermined pitch whenever the number of strokes of the cutter (3) reaches a predetermined number. Accordingly, even when the cutting edge of the cutter cuts into the rest and becomes deteriorated, the cutter need not be exchanged immediately, the life of the rest can be lengthened and the number of sheets cut before exchange is necessary can be drastically improved.

    摘要： There is provided an improvement in an apparatus for cutting a profile of a selected shape from a natural sheet material at a given location, which apparatus comprises a cutting platen having an upper generally flat cutting surface and a lower generally flat support surface. The platen is movable to the desired position relative to a cutter which moves along an axis downwardly against the cutting surface to cut the preselected shape from the natural material. In accordance with the improvement, there is provided a fixed anvil having a flat force reaction surface parallel to and facing the supporting surface of the platen so that the cutting action is against the anvil. The anvil can also form the structure for supporting the platen as it is moved into the cutting position.
