Abstract: Each glass plate, brought to a high temperature, arrives flat on a conveyor by resting there by its lower face, is picked up by its lower face, is turned over to bring its initially lower face into the upper position, and is then placed on a bending form the profile of which it assumes. A device for accomplishing this process has a pivoting plate capable of turning the glass plate over, a bending form, optional pressing means, and a frame for conveying bent glass plates to a succeeding work station.

Abstract: A press bending apparatus includes a shaping station having an upper mold with a shaping surface having a generally concave downward elevational configuration and a lower mold with an apertured shaping surface complementing the shaping surface of the upper mold. A vacuum shuttle transfers heat softened glass sheets from a heating furnace to the shaping station where it deposits the glass sheets on the lower vacuum mold. The glass sheet is shaped between the molds. A rotating arrangement rotates the lower mold and the shaped glass sheet held thereagainst by vacuum from a first position wherein the shaping surface of the lower mold faces upward to a second position wherein the shaping surface of the lower mold faces downward. The shaped glass sheet is then deposited on a tempering ring. A rotating arrangement maintains vacuum in the lower mold as the mold rotates.

Abstract: An apparatus for bending a glass sheet has at least a lower mold, a conveyor device for conveying the heated glass sheet to a prescribed position over the lower mold, and a plurality of rolls for supporting the glass sheet in the prescribed position. A method of bending a glass sheet is carried out by utilizing the apparatus. The apparatus also includes a device for lowering the rolls to a position below the shaping surface of the lower mold, and an arrangement in the lower mold for accommodating the rolls which have been lowered. The apparatus may additionally have an upper mold coacting with the lower mold. The method comprises the steps of lowering the rolls below the shaping surface of the lower mold, transferring the glass sheet from the rolls onto the shaping surface of the lower mold while the rolls are lowered, and bending the glass sheet into conformity with the shaping surface of the lower mold under gravitational forces. The method may also include the step of lowering the upper mold simultaneously with the downward movement of the rolls, and press bending the glass sheet between the upper and lower molds.

Abstract: A method of and apparatus for bending glass sheets to relatively sharp angles. The apparatus includes a sectionalized primary press bending member having articulated end sections for sharply bending portions of a glass sheet about lines superheated by a radiant energy heat source located above the primary press member. A reciprocal brake bar is extended into engagement with the glass sheet along the heated focal line to assist the articulated press end sections in bending the glass. Clamping devices can be used in lieu of the brake bar to secure the heat-softened glass sheet to the press member shaping surface during bending. A supplemental press member, mounted above the primary press member, is provided with shaping elements having shaping surfaces complemental to the shaping surfaces of the primary press articulated end sections for pressing the glass end portions therebetween into conformity with these shaping surfaces.
