METHOD OF AND APPARATUS FOR BENDING GLASS SHEETS

摘要

A method of and apparatus for press bending sheets into complex shapes wherein the apparatus includes at least one press member of outline or ring-type construction having an array of spaced apart shaping rail elements mounted in a composite array and adapted to pass upwardly between adjacent conveying rolls to contact and support the undersurface of a sheet of heat-softened glass. Another array of shaping rail extensions is disposed above the conveying rolls mounted for movement into and out of association with the spaces between the spaced apart shaping rail elements of the first mentioned array prior to the final bending of the glass sheet to form a more continuous support and thus assure a smooth edge portion in the final formed product.
