Abstract
A method and apparatus for pressing curved laminated glass having an adhesion interlayer between curved sheets of plate glass by passing the curved laminated glass through a pair of press rolls. A level of a contact position between said pair of press rolls and an inclination angle of a line connecting axes of said pair of press rolls with respect to a curved surface of the laminated glass are controlled to control a posture of said pair of press rolls upon movement of the laminated glass so as to correspond to controlled rotation of said pair of press rolls. A line of action of a press pressure is directed along a direction substantially normal to the curved surface of the laminated glass, and the location of application of the press pressure is level-shifted along the curved surface of the laminated glass. The posture of the press rolls is controlled in accordance with prestored data sampled along the curved surface of the laminated glass.
