METHOD AND DEVICE FOR FLOOR PANELS PRODUCTION Russian patent published in 2005 - IPC

FIELD: equipment for laminated structure compaction, particularly to produce floor panels.

SUBSTANCE: compaction device comprises two heated compaction plates, gripping transporting means, means for moving heated plates to laminated structure and compacting thereof. Gripping transporting means is adapter to clamp laminated structure and to move thereof to space between compaction device plates. Means for moving heated plates are controlled in such a way that heated plates simultaneously reach laminated structure and simultaneously move away from it. Plate area, which transfers pressure to laminated structure is at least 1 m³. Temperature and pressure is applied to laminated structure in the device from both sides thereof, which results in gluing structure layers together. Heating for glue melting is performed simultaneously from both structure sides. Laminated structure is adapted to produce floor panels having width of at least 300 mm and length of at least 800 mm and thickness not more than 15 mm. Grooves and ridges are cut in side panel edges. Panels have additional locking means to connect panels without glue.

EFFECT: prevention of shift during transferring heat.
