Device for preliminary bonding of laminated glass

A preliminary bonding device of a laminated glass, which bonds superposed curved glass plates together through an interlayer that is sandwiched between the glass plates by sandwiching and pressing the glass plates from both outside surfaces of the superposed curved glass plates, the preliminary bonding device comprising:

• an upper roll pressing means having a plurality of independent upper rolls that are arranged in a row along an upper surface of the curved glass plate and pressing the curved glass plate by the each upper roll from an upper surface side of the curved glass plate;
• a lower roll pressing means having a plurality of independent lower rolls that are arranged in a row along a lower surface of the curved glass plate and pressing the curved glass plate through the lower rolls from a lower surface side of the curved glass plate;
• a lower side flexible roll that is contiguous with each top end of the plurality of lower rolls and is able to curve;
• and
• a lower side roll driving means that drives a rotation of the lower side flexible roll, and
• the curved glass plates being press-bonded together by the upper rolls and the lower side flexible roll by pressing the lower side flexible roll against the lower surface of the curved glass plate through the lower rolls by the lower roll pressing means.
