ABSTRACT:
When heating and bending glass sheets in a furnace, it has been found to be desirable to raise the glass sheets towards the furnace heat sources to increase obtainable temperature differentials and reduce heating power. An apparatus for bending the glass sheets includes an elongate furnace divided along its length into a plurality of heating zones, each heating zone having an upper part. A plurality of heat sources are arranged in the upper part of such heating zone and a plurality of carriages are arranged in succession along the length of the furnace below the furnace heat sources. A drive device propels the carriages through the zones of the furnace in intermittent steps, and a mould lift raises the bending mould towards the furnace heat sources. The bent glass sheet may be used in the manufacture of a vehicle glazing.
