Method and apparatus for supporting the middle section of a glass panel to be bent in a mold |
摘要 |
The invention relates to a method and apparatus for supporting the middle section of a glass panel to be bent in a mold. During a preheating process of a glass panel, its middle section is supported by middle support elements carried along with a mold carriage. At the start of a bending process, the middle support is released by pushing bearing rods through the bottom of the mold carriage. The middle support for the glass panel is lowered upon the bearing rods gradually under the control of glass panel thermometry. A controlled hoisting and lowering of the bearing rods is performed by a hoisting and lowering mechanism present in a carriage elevator. The invention makes it possible to implement a middle support also in an automatically operating serial furnace.
