Abstract (en)

[origin: WO9411168A1] A method and apparatus for manufacturing board- and bar-like products from a thermoplastic or a fibrous material having thermoplastic as the binding agent, and a product manufactured thereby. The raw material used is primarily recycled material which is dry-comminuted to a particle size which is optimal considering the strength and rigidity of the product. The pulp still warm from the comminuting is formed by means of vacuum into a mat of even thickness. It is heated rapidly to the molding temperature by means of hot gas, by using the countercurrent principle, and is thereafter compressed into an endless blank. This blank is molded by extrusion or compression into a product, which is cooled immediately.
