PURPOSE: To prevent burrs from developing at the shearing work of a green sheet. CONSTITUTION: By performing shearing work under the condition that the green sheet G sealed by a bag P is placed on the lower cutting edge 44 of a die, the burr of the green sheet G can be prevented from developing, since the bag P performs the roll as buffering sheet, which scatters the contact pressure between an upper cutting edge 42 and the lower cutting edge 44 and the green sheet G. |
