<p>1,157,406. Reinforced glass sheet. COMPAGNIE DE SAINT-GOBAIN. 20 Feb., 1968, No. 8206/68. Heading C1M. Reinforced glass sheet is manufactured by forming a continuous ribbon of glass 4 on a bath 1 of molten metal 3 permitted to achieve a desired uniform width and thickness, continuously inserting metal reinforcement 9 into the formed and moving glass ribbon, maintaining the temperature of the ribbon of glass above 900-950‹ C. as it travels on the bath for a time sufficient to give a fine polished upper surfaee and then cooling until the ribbon is sufficiently rigid to be removed from the bath and conveyed to an annealing lehr without damage. A grooved roller 7, driven by cable 36 from a motor 34, presses the metal wires or mesh reinforcement 9 into the glass ribbon over a bar 5, e.g.. of graphite, immersed in the molten metal 3 and with openings 6 for flow of the molten metal. The wire mesh 9 from either feed roller 32 or 33 is passed between rollers 46 which may shape the mesh and over a guide roller 31 to a lock 15a fed with inert or reducing gas and thence to roller 7. The lock 15a can be closed at the top by a bar when not in use. The height of the roller 7 is adjustable so that the depth of penetration of the wire can be controlled. An arcuate cooler 30 and the inside of the hollow roller 7 are fed with cooling liquid from pipes 43.</p> |
