ABSTRACT:
A laminate consisting of a number of air-permeable sheets of a material is placed on the supporting surface of a table, and a major portion of the periphery of the laminate, inclusive of a lower surface thereof, is covered with a sheet impermeable to air. A suction pipe is arranged on the supporting surface along at least one side surface of the laminate and has a suction port faced toward the one side surface. A periheral portion of the suction port is covered with the air-impermeable sheet, and the laminate is compressed in the direction of its thickness by evacuating air from within a space defined by the air-impermeable sheet by vacuum producing means connected to the suction pipe. The air-impermeable sheet and laminate can be moved together with the suction pipe in parallel relation to the supporting surface, and they can be stopped at a desired position, during the evacuation process.
