<p>A cutting frame is provided, which has the high cutting effectiveness and reduces the total cost by the cutting effectiveness. A cutting frame is constituted as follows. A rectangular monomer(200) comes into contact with the respective other rectangular monomers(210,230) but does not come in contact with the rectangular monomer(220). Among combinations composed of four adjacent rectangular monomers, cutters are mounted corresponding to the arrangement composition of rectangular monomers to make arrangement of an island-shape excessive portion on the center.</p> |
