GLUE APPLICATION DEVICE FOR APPLYING GLUE TO PARTICLES， DEVICE OF OR FOR AN INSTALLATION FOR PRODUCING PRESSED BOARDS， METHOD FOR PREVENTING THE DEPOSITION OF GLUE AND/OR PARTICLES， AND METHOD FOR APPLYING GLUE TO PARTICLES

The invention relates to a glue application device for applying glue to particles， a device of an installation for producing pressed boards， a method for preventing the accumulation of glue and/or particles and a method for applying glue to particles. In the method for preventing the accumulation of glue (80) and/or particles (26， 26B) on wall inner surfaces of at least one channel (22) for conveying glue-coated particles (26B)， protective air (93) is fed to the at least one channel (22) from at least one side， in a protective air flow direction (92) approximately parallel or oblique to a central flow direction (32) of a particle flow consisting of transport air (24) having glue-coated particles (26B)， such that the protective air (93) forms a protective air jacket (132) between the particle flow and at least one wall inner surface of the at least one channel (22).
