Glass pane curving - using carrier rods at edges of roller hearth with swing action

摘要

The assembly to shape glass panes, while at softening temps., into a two-dimensional curvature, has carrier rods at the edges of a roller hearth to form a flat laying surface to support the glass pane during bending. At least one edge zone of at least some carrier rods can swing upwards from the horizontal laying surface. ADVANTAGE - The system gives a precisely set curvature to glass panes, even in large sizes, and in a variety of glass thicknesses.
