Abstract

1388958 Drawing sheet glass GLAVERBEL 5 July 1972 [20 Aug 1971] 31485/72 Heading C1M In a method of manufacturing sheet glass by drawing a continuous ribbon from a pool of molten glass, gas displacing forces are applied at at least one pair of successive positions along the ribbon, the gas displacing force at one position being directed to impel gas in an opposite direction across the ribbon to the direction in which gas is impelled at the other position. The positions are separated by a distance such that the difference in glass viscosity is less than 102.5 poises and at least one of the positions is where the glass is at a viscosity between 107.6 and 1013 poises. The gas displacing forces may be applied by ejectors similar to those described in Specification 1,388,957. Such ejectors may be situated in either the drawing chamber or an associated annealing shaft. Pairs of ejectors may be mounted on each side of the ribbon. In one embodiment (Figs 4 and 5), the operation of two pairs of ejectors 40, 42 and 41, 43 is controlled by a device 48 such that as one ejector 40 operates the other ejector 42 is inoperative, while the diagonally opposite ejector 43 of the second pair operates and ejector 41 is inoperative and vice versa. Mechanical means such as propellers may be employed as an alternative to ejectors. The process is applicable to the Pittsbury, Libbey-Owens and Fourcault processes and to processes involving the floating of molten glass on another molten material, e.g. tin. Specification 1,388,956 is also referred to.
