Abstract (en)

The method involves supplying small plant parts i.e. small wooden parts, to a press area (5). The parts are compressed and are shifted in an extrusion direction. The parts are subjected to steam, where steam admission takes place via short-term steam injection. Temporal progression of the injection is aligned such that a binding agent is temporarily heated to a peak temperature, where predominant part of water in the agent evaporates and makes the agent to gel form. Mixing temperature supporting energy entry of injection operation is set in a strand according to the injection. An independent claim is also included for a device for producing a profile material.
