PURPOSE: To avoid the degrading influence on a laminated article, and to well keep the quality of the laminated article by freely making an elongation of a frame in a hot plate compressing time, preventing the deformation and preventing covers of a front face and side faces from deforming in a vacuum absorbing time.
CONSTITUTION: Front face covers 302, 304 and side face covers 306, 308 are made so that frames 12, 14, 16, 18 are abutted by being slid so as to expand and contract in the longitudinal direction at the upper part, and abutted at the lower part. Therefore in the hot plate compressing time, the frame can be expanded, and the deformation can be prevented. The deformation of each frame is prevented by connecting each frame with a connection reinforcing member 398 and opposing to a pressing force applied from a vacuum cover device 30 side in the vacuum absorbing time. In such a way, the quality of a laminated article can be well kept by avoiding the degrading influence on the laminated article.
