ABSTRACT:
An apparatus for hot pressing boards comprises a conveying and setting mechanism for setting a board put on a caul plate in a predetermined hot pressing position, and a hot pressing mechanism including a hot plate and a spacer, the board being hot pressed in a closed space defined by the hot plate, the caul plate and the spacer. The conveying and setting mechanism includes a conveying member for supporting the caul plate in a state free from frictional contact with any other member while the caul plate is conveyed to a hot pressing section, and a setting member for supporting the caul plate in succession to the conveying member and setting the caul plate in the hot pressing position, the setting member being retreated to a position free from interference with hot pressing operation after the setting of the caul plate in the hot pressing position.
