Abstract
The disclosure relates to a method for producing a wood material panel with at least one layer with an inhomogeneous density profile, including the steps: scattering a multitude of wood particles to produce a particulate cake, pressing the particulate cake to form a layer of the wood material panel, and scattering different pre-determined quantities of wood particles in at least two areas within the particulate cake.
Claims10
A method for producing a wood material panel, comprising:
- (a) scattering a multitude of wood particles to produce a particulate cake, wherein at least one adhesive is applied to at least some of the wood particles prior to and/or during scattering,
- (b) pressing the particulate cake under high pressure and at a high temperature to form a wood material panel, and
- (c) introducing different quantities of at least one additive at different positions within the particulate cake during the scattering of the wood particles.
