  • Patent number: 8444407
    Abstract: The invention relates to an installation for applying glue to fibers for the production of fiberboard, especially MDF board or similar wood material board. Said installation comprises a fiber feed unit having at least one fiber feed conduit which opens into a fiber exit tube via a fiber deflection element and receives the air that is used to transport the fibers, a chute which is located downstream of the fiber exit tube, a glue application device which has spray nozzles for spraying the fibers that emerge from the fiber exit tube and enter the chute with drops of glue, and a collection device, located downstream of the chute and having an air-permeable transport belt for collecting and optionally carrying off the fibers and a suction device located below the transport belt for suctioning air from the chute through the transport belt, the suction device having one or more suction boxes to which one or more suction pipes are connected.

  • Patent number: 7987884
    Abstract: The invention relates to an installation for applying glue to fibers for the production of fiberboard, especially MDF board or similar wood material board. Said installation comprises a fiber feed unit having at least one fiber feed conduit which opens into a fiber exit tube via an arched fiber deflection element and receives the air that is used to transport the fibers, a chute which is located downstream of the fiber exit tube, a glue application device which is located e.g. between the fiber exit tube and the chute and which has spray nozzles for spraying the fibers that emerge from the fiber exit tube and enter the chute with drops of glue, and a collection device, located downstream of the chute and having a transport device for collecting and optionally carrying off the fibers.

  • Patent number: 6780002
    Abstract: At the end of an array of rollers of a spreading head for wood particles for the production of mats to form particleboard, rollers of the array are driven at a higher speed than the rollers of the fine-particle spreading portion and baffles are provided below the higher speed rollers to scatter the particles backwardly into the fine-particle region and form an intimate mixture of the coarse and fine particles.
