Abstract

Extracting glass from a furnace to form a continuous ribbon. F6B. By letting it flow under hydrostatic pressure via a slot through a cylindrical piece included in the furnace envelope at a height below the level of the liquid glass in the furnace. The cylindrical piece may be placed in different positions by rotation to orient the slot according to the required mode of travel of the ribbon, or to cut off the flow. It may be of graphite which can be protected by an inert gas or by metallising. Because the glass is drawn from beneath the surface, it is at a homogeneous temperature.
