METHODS AND ARRANGEMENTS FOR CONTINUOUS MANUFACTURE OF BUILDING PANELS
A continuous press arrangement (80) for continuous pressing or manufacture of a product comprising at least one veneer layer, such as wood veneer. The arrangement comprising an upper rotatable inlet drum (42) connecting to an upper rotatable outlet drum (44) via an upper continuous press belt (40) and a lower rotatable inlet drum (43) connecting to a lower rotatable outlet drum (45) via a lower continuous press belt (41). The upper and lower press belts are configured to form a product path (6) there between for feeding a product (9) in a feeding direction (FD) in response to rotation of said drums or displacement of the press belts. An upper and a lower press table (51, 51') each comprises at least one displaceable pressure cushion (55, 55') configured to be displaced into sealing abutment with the press belt (40, 41) for facilitating a pressure zone (70) preferably in shape of a pressurizable volume extending along at least a portion of the path (6). The inlet drums are configured to form respective angles (phi) between the respective press belts (40, 41) and the product path (6) at a position being downstream the inlet drums and upstream the pressure cushions (55, 55') or press tables (51, 51'), in the feeding direction (FD). The size of the angles (phi) is adapted by adapting a distance between the respective centre axis (Ax1, Ax2) of the inlet drums, such as a vertical (V) distance.
