Abstract

In an apparatus for the continuous gluing of wood chips and the like with liquid glue, the chips are raised from a longitudinally moved chip bed and are returned into the same in free fall in the form of chip mists. The glue is exclusively supplied to the chips by pressure atomization by means of a plurality of pressure atomizing nozzles. In order to achieve good gluing quality with limited mixer dirtying and easy operation, glue distribution takes place in the chip mists substantially over the entire length of the chip bed and alternately at least one nozzle is closed, while at least one nozzle is open.
