Abstract
An apparatus for supporting and conveying glass sheets on a series of conveyor rolls having arcuately curved central portions normally disposed in an upper common horizontal plane for supporting a flat sheet of heat-softened glass to be bent and pivotable into a lower angular position out of engagement with said flat sheet upon engagement thereof along its marginal edge portions by the shaping rail of an upwardly movable female press member. Each conveyor roll is provided with a two-piece coupling comprised of a first section secured to the conveyor roll and a second section operatively connected to a drive arrangement. The sections are angularly rotated relative to each other to effect precise angular adjustments therebetween for varying the angular attitude of the associated conveyor roll in its lower position of use.
