Abstract
An apparatus for supporting and conveying thin glass sheets through a tempering area including a series of upper and lower conveyor rolls for continuously advancing heated thin glass sheets between the opposed blastheads of a tempering section. The upper series of rolls are specially configurated for accommodating a common drive element for both series of rolls and are mounted for floating movement as well as being individually pivotable into an inoperative, out-of-the-way position to facilitate access into the tempering area for maintenance and cullet removal.
