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. The installation is characterized in that at least a part of the fiber deflection conduit is configured as a subdivided conduit having a plurality of partial conduits, said conduit being subdivided by one or more dividing walls that extend in the axial direction.
