Abstract
A continuous press arrangement for manufacture of building panels comprises an upper rotatable inlet drum connected to an upper rotatable outlet drum via an upper continuous press belt, and a lower rotatable inlet drum connected to a lower rotatable outlet drum via a lower continuous press belt. The upper and lower press belts form a product path therebetween for feeding a product in response to rotation of one or more of the drums. Upper and lower press tables each comprise a displaceable pressure cushion extending along at least a portion of the path and facilitate a pressure zone between the press table and the press belt. The press table comprises a displacement groove and the pressure cushion is configured to be at least partially received in the displacement groove. The pressure cushion comprises a friction seal element configured to be in contact with the press belt.
