GLASS FLOAT CHAMBER

摘要

The invention relates to a chamber for floating glass on a bath of molten metal comprising an upstream wall (3), a downstream wall (4) and two lateral walls (1, 2), rolls (8) for driving the glass in a direction of travel from upstream to downstream, a lateral wall comprising a shoulder (21, 22) resulting in a reduction in the width of the chamber in the direction of travel of the glass, said shoulder (21, 22) starting at a first point (25, 25') and terminating at a second point (26, 26') of the lateral wall, said points being in contact with the surface of the bath of metal, the vertical plane (23) passing through these two points (25, 26) forming with the vertical plane (24) parallel to the direction of travel of the glass and passing through the first point (25), an angle inside the chamber which is greater than 150°. The geometric features of the shoulder (21, 22) reduce the lateral reciprocal motion of the ribbon emerging from the chamber.
