  • Publication number: 20180243940
    Abstract: The disclosure relates to a method for finishing a wood board with an upper face and a lower face. A layer of liquid synthetic resin is first applied at least onto the upper face or the lower face, and at least one paper ply soaked with a synthetic resin is then applied. The structure is then pressed in a press under high pressure and at a high temperature, wherein the synthetic resin melts and is connected to the upper face or the lower face of the wood board. The invention is characterized in that the upper face and/or the lower face is provided while still having a press skin and in an ungrounded state, and the layer is applied so thinly that the liquid synthetic resin is completely drawn into the press skin, the layer is not actively dried, and the paper ply is positioned on the press skin.

  • Patent number: 10029452
    Abstract: A method for producing decorative prints having identical quality on at least two carrier materials includes the following steps: providing at least one print motif; converting the at least one print motif into at least one high resolution electronic data set; reducing the resolution of the at least one high resolution electronic data set; creating at least one first print decor on at least one first carrier material by means of the at least one resolution reduced electronic data set; creating at least one print cylinder for a gravure printing process by using at least one resolution reduced electronic data set, with the resolution reduced electronic data set identical to or different from the resolution reduced electronic data set used for the digital printing; and creating at least one second print decor on at least one second carrier material by using the at least one print cylinder.

  • Publication number: 20160222658
    Abstract: A solid-borne-sound underlay based on a wood-plastics-composite material. A process for production of the solid-borne-sound underlay is also provided. The process involves the step of applying a mixture of wood particles and plastic particles to at least one first conveyor belt with formation of a preliminary web and introduction of the preliminary web into at least one first continuous-flow oven. The process also involves the step of transfer of precompacted preliminary web into at least one twin belt press. The process also involves the step of cooling compacted solid-borne-sound underlay made of wood-plastics-composite material in at least one cooling press.

  • Patent number: 8336272
    Abstract: A device for locking two building boards connected to one another in a direction (V) perpendicular to a visible side. The device includes a first building board with a lateral edge (I) and a first groove and running parallel to the visible side. The device further includes at least one second building board with a lateral edge (II) and with a second groove and running parallel to the visible side, and a locking element that is placed in the first groove of the first building board to engage in the second groove of the second building board, when both grooves have reached an overlapping position after the connection of the building boards by a vertical lowering movement.

  • Publication number: 20090173032
    Abstract: A device for locking two building boards connected to one another, in particular flooring panels with a core of wood material or wood material/plastic mixture, in a direction (V) perpendicular to a visible side. The device includes a first building board with a lateral edge (I) and a first groove provided in the core of the building board and running parallel to the visible side. The device further includes at least one second building board with a lateral edge (II) and with a second groove provided in the core of the building board and running parallel to the visible side, and a locking element that is placed in the first groove of the first building board in order to engage in the second groove of the second building board, when both grooves have reached an overlapping position after the connection of the building boards by a vertical lowering movement.
