Title: Improvements relating to the manufacture of flat glass in continuous ribbon form
IPC: C03B18/02
Filed: 1955-10-18
Abstract: 797,102. Glass manufacture. PILKINGTON BROS. Ltd., and PILKINGTON, L. A. B. Sept. 4, 1956 [Oct. 18, 1955], No. 29760/55. Class 56. In the manufacture of flat glass in continuous ribbon form, a fire finish is obtained by passing the ribbon, whilst still pliable, through a bath of molten metal which flash-heats the ribbon to melt the surfaces without affecting substantially the strength of the ribbon as a whole, the bath being progressively cooled towards the exit end whereby the fire-finished surfaces are hardened sufficiently to prevent marring of the surfaces by the rollers of the lehr. In Fig. 1, the ribbon 10 is formed, from glass flowing over a lip 4, by rollers 6, 7 and is passed, between cooling means, e.g., water-boxes 21 and, if desired, water cooled rollers, into the bath 15 of molten metal, e.g., of tin or a mixture of aluminium and tin. The thrust of the rollers,6, 7 on the ribbon 10 forces it into that part of the molten metal which is heated by heaters 23 and is substantially isolated from the rest of the bath by a partition 24. The glass being subjected to flash-heat in the first part of the bath, passes beneath the partition in the second part where the temperature is lowered by coolers 25. The surfaces of the ribbon may be further hardened between the bath and the traction roller 19 of the lehr by air jets 22. The bath is prevented from oxidizing by the exclusion of air by mains gas supplied through pipes 28, 29. The centre area of the bath is isolated from atmosphere by members 26, 27 which dip into the bath and, if desired, mains gas may be supplied to the centre area by pipes 30, 31. This may be rendered unnecessary by depressing the centre of the cover 13 so that it is immersed in the bath. The lehr may be arranged vertically and the ribbon may be formed as described in Specification 722,554.
