ABSTRACT:
A process and apparatus for adding glue to a flow (L) of loose wooden material, in particular a flow of wood chips and fibers, in which the wooden material is introduced through an inlet (3) into a mixer device (4). The glue is sprayed onto the flow of wooden material, internally of the mixer device (4), by nozzles (21) arranged in proximity of the inlet (3). The mixer device (4) is crossed by a flow of hot air. The wooden material, mixed with the glue, after having crossed the mixer device, drawn by the flow of hot air, is removed via an outlet (10) and sent on to subsequent work operations. The invention serves in particular in the manufacturing of wood-chip and fiber panels. The panels obtained are of high quality, being practically devoid of surface imperfections.
