<p><PICT:1104575/C1/1> In the float-glass process at least one partition 15 dips into a liquid seal over the glass sheet. Both inlet and outlet of the glass ribbon may have such seals. Less inert gas wastage, higher usable pressures and the utilization of differing atmospheres in spaces above the bath are possible. Carbon rollers 16 guide the ribbon under the partitions. Carbon pieces may restrain the sides of the ribbon.</p> |
