<p>An object of the invention is to achieve smooth feeding and discharging of even a laminate of sheet material which largely changes in volume depending on suction and that can keep a desired cutting accuracy. With a configuration as shown in Fig. 1C, particularly in a case of cutting a highly compressive sheet material, an attempt to secure a distance Hc long enough to facilitate feeding and discharging of a to-be-cut material (25) causes an increase of a distance Dc, resulting in deterioration of cutting accuracy. When a sealing device (21) is used, in a pressing state shown in Fig. 1A, it is easy to satisfy a condition of the distance Ha < Hc, thus obtaining the distance Da < Dc, so that the to-be-cut material (25) can be sufficiently covered with a sealing sheet (27a) and moreover, the cutting accuracy can be enhanced. In a non-pressing state shown in Fig. 1B, a condition of the distance Hb > Hc can be satisfied, thus allowing easy feeding and discharging of the to-be-cut material (25) which may be bulky.</p> |
