METHOD OF FABRICATING PANELS, BOARDS, STRUCTURES Russian patent published in 2012 - IPC B27M1/02 

FIELD: process engineering.

SUBSTANCE: proposed method comprises gluing materials of panels, boards etc together in their conveyance along production zones. In first zone, article is formed in one plane with clearance between workpieces. Glue components or binders and hardeners with additives facilitating gluing process are applied on opposite surfaces to be glued together. Workpiece are moved together and fed into preset force into lateral tool and closed gages. The latter are made up of drive rollers, rollers and lateral tools. In second zone, billets clamped by rollers are squeezed to allow reduction of 2-50%. In third zone, drive rollers and rollers push the article between lateral tool. Equal specific pressure is maintained in controlled intervals for gluing purposes. Drive rollers, rollers and surfaces preserve obtained shape. In fourth zone, article is separated, specific pressure is maintained, article is finished, article shape is fixed by package or in structure. Continuous article is cut by moving saw. Panels with heaters are assembled into multi-layer structure, say, wall panels, flooring, etc.

EFFECT: higher efficiency, strength, improved geometry.
