  • Patent number: 6526781
    Abstract: A method for roll forming a heated glass sheet utilizes a forming conveyor (62) including forming rolls (66) that are pivotally moved upwardly between horizontal rolls (46) of a horizontal conveyor (44) on opposite sides of a centerline (C/L) of the horizontal conveyor to rollingly engage the heated glass sheet above a plane of conveyance of the horizontal conveyor at its centerline to roll form the glass sheet in cooperation with a forming press (80) having rotatable forming members (82) that rollingly engage the heated glass sheet from above. A second set of forming rolls (68) cooperates with the first set of forming rolls (66) to provide the roll forming. First and second sets of roll cradles (76,90) are mounted by pivotal supports (128,142) on associated first and second carriages (154,156) and moved by first and second actuators (78,92). Lateral movement of the carriages (154,156) provides versatility in the glass sheet shapes that can be formed.
