Method and apparatus for bending glass sheets to complicated shapes including an S-shaped transverse bend |
摘要 |
The invention involves a method and apparatus for bending glass sheets to an S-shaped transverse bend with a longitudinal bend. The heat softened glass sheets are serially conveyed onto a gas hearth bed having a downwardly curved end portion at the downstream end thereof such that the glass sheet curves into conformation with the gas hearth, then by means of a curved outline mold lifting the glass sheet vertically into conformation with an overlying vacuum mold, holding the shaped sheet into contact with the vacuum mold by vacuum while lowering the outline mold, then moving a shuttle ring beneath the glass sheet, discontinuing the vacuum such that the glass sheet is deposited onto the shuttle ring and then moving the shuttle ring and glass sheet laterally for further processing.
