Abstract: Fiberboard or chipboard is made by first comminuting vegetable starting material in a first comminutor into a stream of loose plant particles with silicate particles. Then, in a first classifier silicate particles of a diameter of less than 50 ?m are separated from the plant particles of the stream. The plant particles remaining in the stream are then glue-coated, and the stream is pressed into fiberboard or chipboard.

Abstract: The invention relates to a material board, in particular an engineered wood board (1) comprising at least one core layer (2) made of strands (3), and outer layers (4, 5) made of chips (6), characterised in that one or both of the outer layers (4, 5) is/are designed as partial-coverage outer layers such that individual strands (3) extend at least partly through the outer layer (4, 5) up to the board surface, thereby forming interruptions in the outer layer (4, 5).

Abstract: A press for making a continuous sheet from composite material has upper and lower press belts having respective lower and upper reaches that vertically spacedly confront one another across a press gap having an upstream inlet end and a downstream outlet end, and that have transversely spaced outer edges extending in the direction. The belts are advanced direction and thereby draw a mat of the composite material in the inlet end, compress it into the sheet, and expelling the sheet from the downstream end. Two transversely spaced elastic seal strips extend in the direction in the gap and are each engaged between a respective one of the outer edges of the upper belt and the respective outer edge of the lower belt. Each belt has at each of the edges a surface in engagement with the respective edge strip and having an average peak-to-valley height of less than 1 ?m.

Abstract: A rubber sheet is made from rubber-containing granules by first coating the rubber granules with a binder, then forming the coated rubber granules into a mat having a core layer with a low moisture level of less than 5% and a pair of outer surface layers, and then, without substantially increasing the low moisture level in the core layer, setting in at least one of the outer layers a high moisture level of 10% to 50% by weight and thereby imparting to the mat an inhomogeneous moisture profile. The mat with the inhomogeneous moisture level is then hot-pressed with pressure and heat so as to vaporize moisture in the one outer layer and drive steam into the core layer, and the hot-pressed mat is cured.
