Abstract: A device for the production of reinforced molded plastic products such as small boats and the like, comprising molds mounted on an endless conveyer which is enclosed in an at least partly gas-tight chamber, for forming the products with hardening and subsequent curing in the molds themselves, the chamber having work access openings at least at a lower part of one wall, thereby providing a working space, and including means to exhaust gases that evaporate from the raw materials used for the plastic products.
