Abstract (en)

[origin: CN108943321A] The present invention relates to a method for pressing a pressed material mat in the process of manufacturing an artificial board in a continuous pressing machine and a corresponding continuous pressing machine. The pressing machine comprises a pressing machine rack (1), at least one upper pressing plate (5) and at least one lower pressing plate (6), pressing cylinders (7, 8) supported on the pressing machine rack is configured to upload the upper pressing plate and/or the lower pressing plate to regulate a pressing gap between the pressing plates, the pressing plates form an inlet area at theinlet side, the pressed material mat (M) entering the pressing gap are compressed in the inlet area during the compression area, the upper pressing plate and/or the lower pressing plate in the inletarea are partially and periodically lifted and reduced in a pulse mode to allow the pressed material mat in the inlet gap to perform a pressing phase and a pressure reduction phase with a plurality ofpulse change through multi-time period compression and releasing of the pressing cylinders connected with the upper pressing plate and/or the lower pressing plate in the inlet area.
