Apparatuses for making reinforced plates of synthetic resin

Abstract

Abstract AN APPARATUS FOR MAKING A REINFORCED PLATE OF SYNTHETIC RESIN, ESSENTIALLY COMPRISING TWO CONVEYOR BELTS FOR SUPPORTING EACH A STRIP OF FOIL, SAID CONVEYOR BELTS EACH BEING ASSOCIATED WITH FOIL SUPPLY AND FOIL GUIDE MEANS, MEANS FOR APPLYING A LAYER OF LIQUID RESIN ON THE FOIL AND MEANS FOR DEPOSITING PIECES OF GLASS FIBRE ON THE LIQUID RESIN, AND BEING MOUNTED FOR FEEDING THE STRIPS OF FOIL TOGETHER WITH THE LAYERS OF RESIN AND GLASS FIBRE PIECES THEREON, IN A CONVERGING MANNER TOWARDS A NIP BETWEEN TWO CO-OPERATING COMPRESSION ROLLS WHERE THE TWO STRIPPS OF FOIL ARE BROUGHT TOGETHER WITH THE LAYERS OF LIQUID RESIN AND GLASS FIBRE PIECES THEREBETWEEN AND THE COMPOSITE STRIP THUS FORMED IS COMPRESSED TO COMPLETE THE REINFORCED PLATE OF SYNTHETIC RESIN. THE TWO CONVEYOR BELTS ARE SUBSTANTIALLY IN THE SAME PLANE WHILST THE NIP BETWEEN THE TWO COMPRESSION ROLLS IS PERPENDICULAR TO THAT PLANE. SPECIAL EMBODIMENTS COMPRISE THE ARRANGEMENT OF PRESSURE MEMBERS FOR PRECOMPRESSING THE LAYERS OF RESIN AND GLASS FIBRE PIECES ON THE FOIL SUPPORTED BY EACH CONVEYOR BELT, SPECIAL ARRANGEMENTS OF THE CONVEYOR BELTS AND ADDITIONAL MEANS FOR FEEDING A THIRD STRIP OF FOIL BETWEEN THE TWO OTHER STRIPS INTO THE NIP BETWEEN SAID COMPRESSION ROLLS.
