A process and a multi-platen press are taught for carrying out the process of manufacturing derived wood panels, and more particularly OSB panels, in which an endless feedstock mat is shaped from a mixture of wood strands and binder, which after formatting as a mat is introduced between the heated press platens of a multi-platen press. The press platens are in a second level with steam supply channels with steam openings on the feedstock mat fed by steam distribution channels at the edges and in which the wood panels are heated, pressed and cured by means of the contact heat of the steam and the press platens. The mat is shaped from a wood-chip and phenol resin mixture and introduced and laid down in the level(s) of a multi-level press. After a light pre-compaction there follows, in a brief time span, the discharge through the press platens of a small amount of steam at a low steam temperature into the face layers only and the feedstock mat is then quickly compacted to the design thickness of the panel and cured.
