  • Publication number: 20180243936
    Abstract: In a process for the production of a flame retardant and/or strengthened fiberboard, a tailored fiberboard is charged on a processing device at first. Subsequently, a flame retardant and/or strengthening agent is applied to the top side of the fiberboard. The agent applied is sucked or pressed into the fiberboard. This is achieved by generating a pressure difference between the top side and bottom side of the fiberboard.

  • Patent number: 9841234
    Abstract: A drying device for drying coated, elongated work pieces in a continuous process including a transport device for transporting the work piece. For drying an edge or surface of the work piece, heat sources are arranged in a drying chamber. In a drying zone, drying vapor is generated during drying. The vapor is removed by an airflow. The airflow is supplied via a supply channel and fans. A controller is provided to control the fans.

  • Publication number: 20160303761
    Abstract: In a method for producing a fiber board, particularly a hardened wood fiber board, liquid curing material is applied across the entire surface of a top side of the fiber board, wherein less than 500 ml of curing material are applied per m2. By generating a pressure difference between the top side and the bottom side of the fiber board, the curing material will be sucked and/or pressed in. This makes it possible to produce customizable fiber boards at a later time, into which desired contours and grooves can be formed, wherein the required post-processing is simplified and, thus, the fiber boards can be produced in an inexpensive manner.

  • Publication number: 20160303759
    Abstract: A method for producing a partially solidified wood fiber board which prior to partial solidification has already been cut to size, includes the defining of a solidification area. Within the solidification area, solidifying agent is applied onto a top side of the wood fiber board. Particularly with the aid of a pressure bell and/or a suction bell, a pressure difference can be generated between the top side and the bottom side of the wood fiber board for suction of the solidifying agent into the wood fiber board.

  • Patent number: 5298072
    Abstract: An apparatus for painting an edge of a workpiece that is moving in a travel direction generally parallel to the edge past a painting station has a support movable horizontally transversely of the direction in the station and an actuator connected to the support for displacing the support transversely of the direction. A generally tubular casing mounted on the support has a rear end and a front end and a front plate engaged over the front end of the casing is formed with a narrow nose in turn formed with a notch having a shape complementary to the workpiece edge. The front plate is releasably secured over the front end of the casing.
