A press apparatus for curing adhesive on inner adhesion surfaces of substantially continuous wood products () under synchronous compression heating. The apparatus includes at least two presses () having a mutual distance from each other fulfilling the precondition: L/(n&#x2212;1), where L is the working length of each press and n is the number of presses in series.

Press apparatus for wood products

The invention is concerned with a method for the manufacture of a laminated beam out of sheets of veneer as a continous process. According to the method, the sheets of veneer are stacked, in consideration of the sequence of stacking, as glued or non-glued as a continuous setting consisting of a number of layers corresponding to the desired thickness of the beam on a suitable transfer base. This setting is passed on the base into a preliminary press, pressed in the preliminary press, as well as passed into a hot press (2) for the purpose of hardening the glue. In order to permit a more efficient operation of the hot press, in the method a continuous gap (3) free of adhesive and having a width equal to the width of the whole setting is produced in the setting between at least two desired layers of veneer, along which said gap the beam blank is divided (4), after the stage of preliminary pressing, into separate blank lines. The blank lines are then passed into hot-press gaps of their own.
