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 e.g. 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 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 and a suction device for suctioning air from the chute through the transport belt. The installation is characterized in that the spray nozzles or at least some of the spray nozzles can be transferred from a standby position to a working position and vice versa for applying glue to the fibers.
