Extrusion process for the continuous production of organically bound molded parts and device for carrying out the process

摘要

The system coats wood chips or fibres with organic adhesive and feeds them into the space between an inner die (4) and an outer shape (3) using a granular spreader (1). The particulate is compressed by a piston (6) in a repetitive process to produce the extrusion. The bottom end of the die has a tapering profile (5) to allow the compressed material to relax. The final part of the process has the relaxed profile supported between an inner perforated guide (7) and outer continuous belt drives (9). The final, relaxed process applies heat via super heated steam, to set the material. The continuous belt drives are dragged along by the friction contact with the extrusion. The extrusion passes through a final cooling stage to remove residual steam and to dry the extrusion.
