Abstract
The process includes a weighing operation of a mass of material a glue is to be spread on, and thereafter a spraying operation of glue, variably mixed with steam, so that the glue is spread on the wood chips proportionately to a weight of the wood chips. The gluing process is completed in a resin bonder machine comprising a cylindrical body in which two different-diameter and oppositely-pitched helices are rotated to mix the glue and chips. Both the body and the helices are cooled in order to prevent adhesion of glued material thereon.
