Installation for applying glue to fibers for the production of fiberboard

An apparatus for applying glue to fibers for making fiberboard, the apparatus comprising:

• a conduit assembly including a vertical intake conduit, an adjacent vertical discharge conduit, and an arcuate diverting conduit connected between upper ends of the intake and discharge conduits;
• means for blowing fibers into a lower end of the intake conduit, whereby the fibers exit from a lower end of the discharge conduit;
• a downwardly open chute below the lower end of the discharge conduit;
• a collection device including a horizontally moving conveyor below the chute, whereby fibers dropping in the chute form a mat atop the conveyor;
• an annular array of levers surrounding the lower end of the discharge conduit and each having an outer end carrying a nozzle and shiftable between a working position with the respective nozzle engaged between the lower end of the discharge conduit and an upper end of the chute and a standby position out from between the discharge conduit and the chute;
• means for supplying glue to the nozzles for spraying the glue on the fibers descending from the discharge conduit into the chute;
• and
• actuator means for pivoting the levers between the standby positions and the working positions.
