ABSTRACT:
Process for manufacture of plate glass including pouring molten glass onto a bath of molten metal (4) contained in a tank having side wall (1), an inlet wall (2) and an outlet wall (3). The glass is advanced by means to form a glass ribbon (7) and extraction means draw the ribbon in a glass drawing space (II and III). Pairs of baffles (13 and 14) are positioned in the drawing zone between each side edge of the ribbon and the side walls to limit upstream flow of cooler molten metal in a direction towards the inlet wall.
A device for manufacture of plate glass including a tank having an inlet wall (2), an outlet wall (3) and side walls (1) for holding a bath of molten metal (4) onto which molten glass is poured by feed means (6). The glass is advanced by advance means (9) in a drawing space to form a ribbon (7). Pairs of baffles (13 and 14) are positioned in the drawing zone to extend between the edges of the ribbon and the side walls to prevent upstream flow of molten metal in a direction towards the inlet wall.
