ABSTRACT:
In order to provide mixing between the freshly melted glass and that already in a glass melting vessel for spinning glass fibre, the vessel has a lateral extension having inlets for glass beads or pellets. These fall into a reception trough and the freshly molten glass passes over a first weir to a second reception trough normally just below the level of the glass in the vessel. The glass from the trough passes over a second weir. In order to prevent a direct access to the draw bar in the aperture a further trough and weir are provided. The draw bar may have nipples which are largely embedded in the plate so as to delay the onset of cooling as the glass passes through the nipples. This reduces the required temperature of entry to the nipples and enables the use of lower grade materials, such as alloy steel or nickel chromium alloy, for the plate and nipples.
