Carriage to carry mold for bending glass sheets

摘要

This invention relates to a mold carriage for carrying thereon a mold for bending a glass sheet, or a stack of glass sheets to be laminated, placed thereon into a curved shape by heating in a furnace. To locally intensely heat the glass sheet in a selected area to be bent sharply relative to the major area, the mold carriage is installed with a heater to heat a selected area of the glass sheet from underneath, a holder to hold the heater and adjust the position of the heater, and a heater support to support thereon an external heater which is suspended from a separate member disposed in the furnace to heat the afore-mentioned area of the glass sheet from above. The heater support also can adjust the position of the external heater.
