A method is provided for manufacturing a paper layer having a printed pattern for use in panels that at least include a substrate and a top layer. The top layer includes the paper layer. The method may involve providing the paper layer with an inkjet receiver coating by transporting the paper layer relative to a coater in a coating direction. The coated paper layer may be provided with at least a portion of the printed pattern using a digital inkjet printer that includes a housing containing print heads. Providing the printed pattern may involve using water based pigment containing inks. The printed pattern may include a wood motif having wood nerves extending generally in a nerve direction substantially corresponding to the coating direction. Providing the printed pattern may involve a relative motion between the digital inkjet printer and the paper layer during a printing operation in a printing direction substantially corresponding or substantially opposite to the coating direction. The paper layer may be maintained flat inside the housing, or the minimum radius over which the paper layer is bent inside the housing may be larger than 25 centimeters. The paper layer may be fed from a roll, printed upon, and rolled back up again. The inkjet receiver coating may be obtained from a liquid substance that is deposited on the paper layer. The liquid substance may have a viscosity of 10 to 75 seconds Din cup 4 at 20° C.

The present invention has to do with an apparatus for generating a three dimension heating gradient field for curing powder coated wood products. The three dimension heating gradient field is generated with catalytic heater panels having independently adjustable angles and adjustable heat outputs.

A method for the production of grounded panels and to a panel having a core made from a wood material board. The method includes provision of a wood material board, application of a grounding in the form of a synthetic resin layer to at least one topside of the wood material board, application of a coating to an underside, lying opposite the topside of the wood material board, of the wood material board, pressing of the layer build-up consisting of the wood material board, grounding and coating under the influence of pressure and, if appropriate, temperature, division of the grounded and coated wood material board into individual panels, cutting machining of side faces of the panels for the incorporation of connection and locking means, and transport-safe packaging of the grounded panels.

A method may be provided for manufacturing coated panels of the type including at least a substrate and a top layer with a motif. The top layer may be provided on the substrate. The method may involve providing a synthetic material layer on the substrate. A relief may be provided on the surface of the synthetic material layer provided on the substrate. The relief may include a pattern of recesses and/or projections. The relief may be obtained by providing a mask on or in the synthetic material layer. The mask may enable a selective treatment of the synthetic material layer. A material-removing treatment or a material-depositing treatment may be performed on the synthetic material layer, such that the mask at least partially determines the pattern.

A method may be provided for manufacturing coated panels of the type including at least a substrate and a top layer with a motif. The top layer may be provided on the substrate. The method may involve providing a synthetic material layer on the substrate. A relief may be provided on the surface of said synthetic material layer provided on the substrate. The relief may include a pattern of recesses. The pattern may be at least partially determined by at least one print that is applied by inkjet printing. The relief may be obtained by printing a mask directly on the synthetic material layer. After providing the mask, the synthetic material layer may be cured. The mask may provide for selective curing of the synthetic material layer, such that the synthetic material layer is not solidified or solidified at a lesser extent in correspondence of the mask. The not solidified or less solidified portions of the synthetic material layer may be removed by performing a material-removing treatment on the synthetic material layer thereby obtaining the relief. The material-removing treatment may involve removing the mask.

A method for treating a panel of wood-based material to achieve an adhesive-free surface after a decoration (2) has been printed onto at least an upper side of the panel of wood-based material, is distinguished by the fact that a cellulose-free top layer (3) of melamine resin with mixed-in glass beads (5) is applied to the decoration (2), and this top layer (8) is dried before a wear-resistant layer (6) is applied to the top layer (8).
