SYSTEM FOR APPLYING GLUE TO FIBERS FOR THE PRODUCTION OF FIBERBOARD

摘要

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 fib er feed conduit which opens into a fiber exit tube via a fiber deflection el ement and receives the air that is used to transport the fibers, a chute whi ch is located downstream of the fiber exit tube, a glue application device w hich has spray nozzles for spraying the fibers that emerge from the fiber ex it tube and enter the chute with drops of glue, and a collection device, loc ated downstream of the chute and having an air-permeable transport belt for collecting and optionally carrying off the fibers and a suction device locat ed below the transport belt for suctioning air from the chute through the tr ansport belt, the suction device having one or more suction boxes to which o ne or more suction pipes are connected. The installation is characterized in that the suction boxes are configured as cleaning boxes having at least one cleaning device for removing fibers that enter the suction boxes through th e transport belt.
