Float Glass Apparatus With Means For Inserting Wire Wire

The glass ribbon at a temperature of 1050C is brought to its finished width on the float bath. A wire inlay is introduced downwards into the ribbon upper surface by guides which do not touch the glass. The ribbon surface in contact in contact with the float bath is cooled to make the ribbon stiffer. This prevents the introduction of the wire from forcing the ribbon downwards , and aids the control of the depth to which the wire penetrates the glass. After this, the ribbons upper surface is heated to smooth it.
