Abstract:
1. A process for producing a decorated board coated on both sides, including the steps: a) coating a carrier material on the top side and the underside with a liquid glue which can be hardened by heating, b) applying a first web of paper or non-woven material to the glue layer on the top side of the carrier material, c) applying a first or a second powder composition comprising a resin to an upward facing surface of a second web of paper, non-woven material, or film, initially melting or melting the applied first or second powder composition to form a second web molten or initially molten layer, solidifying the second web molten or initially molten layer, and turning the second web so that its upward facing layer faces downward, then applying said second web of paper, non-woven material or film to the glue layer on the underside of the carrier material, d) drying the glue by heating the layer assembly produced by steps a)-c), e1) applying to the top side of the first web the first powder composition with a resin which can be melted and hardened by heating and/or constituents which can react to form such a resin, f1) initially melting or melting the powder layer on the first web to form a first web molten or initially molten layer and subsequently solidifying the first web molten or initially molten layer by cooling, and g) hardening the glue and the resin composition under pressure and heat.
