Abstract

In a process of making sheet material, wood particles of predominantly cellular structure which are large in the direction of the fibres and small in at least one direction at right angles thereto (e.g. wood shavings, wood wool) are mixed with a binder to a moisture-containing non-tacky composition, moulded, and cemented together under compression and under such heat that moisture evaporates, means being provided or afforded by which under the application of pressure vapours escape from all parts of the sheet to the effect that the composition is dried. Water or organic solvents may be added to the wood particles to increase the moisture content, whilst the particles may be softened by pre-heating and compression before being cemented together, and wood dust should preferably be removed from the particles. Other fibrous substances, e.g. asbestos, cotton waste, cork bark, hair, vegetable fibres, may be admixed with the wood particles; also rubber and bitumen. Binders preferred are ureaformaldehyde resins and collagen-containing material (e.g. vegetable-tanned leather), which may be sprayed or dusted on to the wood particles or applied as a suspension in water & c. Reference has been directed by the Comptroller to Specification 631,097.
