ABSTRACT:
Glass sheets arriving at a bending station where their under surfaces are exposed to a hot gas support bed are delivered with minimum misalignment and misorientation by engaging each sheet simultaneously across its entire width with at least two rotating conveyor rolls. The latter are spaced from one another longitudinally of a path of glass sheet travel a distance sufficient to optimize flow of hot gas against the engaged glass sheet surface. This invention enables the leading edge of glass sheets of either rectangular or non-rectangular outline to nest within aligning means located in a fixed but adjustable position at the bending station. Provision is made to handle two or more sheets arriving at the bending station in side-by-side relation.
