ABSTRACT:
Wood fragments are mechanically disintegrated to provide a defibrated material, while avoiding premature agglomeration by avoiding permitting the temperature of the material to rise more than 10.degree. C. as it is being defibrated. The humidity of the defibrated material is reduced, and textile fibres including thermoweldable textile fibres are added to it to provide a composite material. The composite material is made homogeneous by mechanical mixing, with much of the composite material being recycled for further mechanical mixing. The mixed composite material is then pneumatically conveyed through a conduit which branches into a plurality of branches, providing feeds to a battery of lap-forming rollers. The laps thus formed are deposited, superimposed on one another on a conveyor which feeds into a hot-pressing station in which the material is hot-pressed to form a sheet.
