  • Method and apparatus for gluing wood particles
    Patent number: 9061437
    Abstract: A method and an apparatus for gluing wood particles, in particular wood strands, is described, as well as a method for the manufacturing of lignocellulosic products, in particular chip boards, oriented strand boards or fiber boards. Since the wood particles are blended in a blending device with a water-curable binder, in particular with polymeric diphenylmethane diisocyanate and moisture is added to the wood particles outside the blending apparatus, curing of the binder inside the blending apparatus, and as a consequence pollution thereof, can be avoided. Moreover, moisturizing outside the blending device can produce a particular even distribution of moisture.
    Type: Grant
