MOVABLE RESTRICTOR TILES IN FLOAT GLASS APPARATUS AND METHOD OF REGULATING GLASS RIBBON

Method and apparatus for controlling the direction of a glass ribbon, during the production of a continuous glass sheet by the flotation process, in which the molten glass is continuously deposited from a landfill on a molten metal bath where its lateral flow is initially reduced or restricted on said bath by means of tiles or tiles at each edge of the gutter or spillway, the glass flowing forward and spreading laterally beyond the tiles, to form a glass ribbon as it advances through the bath, characterized in that by adjusting the position of these tiles in response to the direction of movement of the glass ribbon, to direct it along a predetermined path, through the bath.
