Abstract
Method and apparatus for producing pressed board and the like in a tiered, multi-opening press, in which the sheet blanks are deposited individually on conveyor platens which are conveyed by conveyor means successively at predetermined intervals to a stacking device. In the stacking device, a predetermined number of platens with their superposed board blanks are successively raised above the conveyor means into retained contact with one another to form a stacked assembly of platens and board blanks. When the predetermined number of platens and board blanks have been stacked, the assembly is lowered onto the conveyor means and transported to tiered racks in an elevator device by which they are successively elevated into alignment with the tiered openings in the multi-opening press to be pressed into board units in a single pressing operation.
