<p>A method of forming multi-curved glass (10) by curving a glass sheet (21) in a longitudinal and a transverse direction. A heated glass sheet is curved along a curved transportation path while being transported to a downstream direction, sandwiched between plural pairs of straight rollers (30, 30) arranged in the curved transportation path with each roller pair being formed of an upper and a lower roller. The glass sheet curved in the transportation direction is, in the next step, curved to the direction perpendicular to the transportation direction by convex forming rollers (33, 35, 83) whose middle portions are swollen and curved and concave forming rollers (34, 36, 82) whose middle portions are hollowed and curved. This way the multi-curved glass is obtained.</p> |
