ABSTRACT:
An apparatus for bending and tempering glass sheets includes a roll conveyor for supporting a glass sheet, the glass sheet having a top and a bottom surface. The roll conveyor includes a plurality of vertically movable rolls for arching the conveyor to a curvature corresponding to a desired degree of bending in the glass sheet. The rolls each have two opposed ends, and at least some of the rolls being deflectable such that at least mid-sections thereof are movable relative to a vertical position of ends thereof. The apparatus further includes a plurality of movable press rollers disposed above the rolls. The press rollers are movable in a vertical direction to apply a pressing force to the top surface of the glass sheet.
