  • Patent number: 9114577
    Abstract: A method for wet gluing of wood fibers, which have been defibrated in a refiner from wood comminuted into chips, in order that these chips, following wet gluing in a gluing zone, can be dried in a dryer, then spread, in a spreading arrangement, to form a fiber mat and pressed, in a hot press, to form a wood-material panel. The wood fibers are transported into the gluing zone, within a conveying tube, in a stream of saturated steam. In order to calm the fiber stream, the conveying tube widens at the start of the gluing zone, within which a plurality of gluing nozzles are situated, as a result of which the speed of the fiber stream is reduced before the first gluing nozzle has been reached, the fibers in the calmed fiber stream are glued with adhesive by the gluing nozzles, and then are fed to the dryer.

  • Publication number: 20130233463
    Abstract: A method for the wet gluing of wood fibres, which have been previously defibrated in a refiner (4) from wood comminuted into chips, in order that these chips, following the wet gluing in a gluing zone (BZ), can be dried in a dryer (5), then spread, in a spreading arrangement (6), to form a fibre mat and pressed, in a hot press (7), to form a wood-material panel of desired thickness, wherein the wood fibres are transported into the gluing zone (BZ), within a conveying tube (R), in a stream of saturated steam, is distinguished in that:—in order to calm the fibre stream, the conveying tube (R) widens at the start (A) of the gluing zone (BZ), within which a plurality of gluing nozzles (D1, D2, . . . Di, . . . , DL) are situated, as a result of which the speed of the fibre stream is reduced even before the first gluing nozzle D1 has been reached,—the fibres in the calmed fibre stream are glued with adhesive by means of the gluing nozzles (D1, D2, . . . Di, . . . DL), and then—are fed to the dryer (5).
