A method to produce a building panel, including: providing a substrate, applying a thermosetting binder in dry form on the substrate for forming a sub-layer, applying a sheet on the sub-layer, and pressing the substrate, the sub-layer and the sheet together to form a building panel, thereby the thermosetting binder of the sub-layer impregnates the sheet from below. Also, a semi-finished product.

Method to produce a building panel and a semi-finished product

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.

Methods and arrangements for continuous manufacture of building panels

A method of manufacturing a building panel. The method includes applying a first binder and free lignocellulosic or cellulosic particles on a first surface of a carrier for forming a first layer, applying a second binder and free lignocellulosic or cellulosic particles on the first layer for forming a second layer, wherein the first binder is different from the second binder, and applying heat and pressure to the first and second layers to form a building panel. Also, such a building panel.

A method of manufacturing a wood-based board. The method includes applying at least one first fibre mat including a first mix comprising lignocellulosic particles and a binder on a carrier, applying a second fibre mat including a second mix including cellulosic particles and a binder on said at least one first fibre mat, and pressing said at least one first fibre mat into a base layer and the second fibre mat into a surface layer simultaneously, thereby forming a wood-based board. Also, to such a wood-based board.

Method of manufacturing a wood-based board and such a wood-based board

A method of producing a building panel, including: providing a core, applying a balancing layer having a first moisture content on a first surface of the core, the balancing layer comprising a sheet impregnated with a thermosetting binder, applying a surface layer having a second moisture content on a second surface of the core, the surface layer comprising a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing, and curing the surface layer and the balancing layer by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel.
