Patent number: 4682997Abstract: Process and apparatus for bending glass plates in horizontal or approximately horizontal position. The invention includes processing the glass plates by means of an installation comprising a glass reheating furnace, a bending station, and a horizontal conveyor for routing the glass plates through the furnace and bending station. A curved surface is placed above the horizontal conveyor in the bending station, and a blower is adapted to deliver a hot air current to bend the glass plates by heating them and applying pressure to urge them against the curved surface to which the desired configuration has been given. Then the glass plates are gently rested on a carrying frame where they continue to be supported, only in part, by said hot air current. The invention makes possible the bending of glass plates individually or, for example, in pairs.Type: GrantFiled: July 10, 1985Date of Patent: July 28, 1987Assignee: Saint Gobain VitrageInventors: Friedrich Halberschmidt, Heinz-Josef Reinmold, Norbert Schwarzenberg, Herbert Radermacher, Kurt Blank, Josef Audi, Luc Vanaschen

Patent number: 4619683Abstract: The invention is concerned with the thermal tempering of glass sheets. In the practice of the invention, the glass blowing assemblies (3, 4) of a glass blowing device for the thermal tempering of glass sheets are formed of a plurality of tubular bodies (15) which are disposed side by side and provided with blowing outlets (20) which are directed towards the glass sheet. The tubular bodies (15) are interconnected by joints (34) and maintained in position by deformable guide rails (24). The shape of rails (24) is obtained by means of adjustable fixing means (40) whose position can be changed by programmable servo-motors (47). The adjustment of fixing means (40) causes with it that of guide rails (24) and accordingly the shape of the glass blowing assembly (3, 4) constituted by the tubular bodies (15) is adjusted to the shape of the glass sheet.The invention finds utility in the thermal tempering of glass sheets which are curved cylindrically and spherically.Type: GrantFiled: August 14, 1985Date of Patent: October 28, 1986Assignee: VeglaInventors: Friedrich Halberschmidt, Heinz-Josef Reinmold, Josef Audi, Cornelius Puetz, Gerd Schubert

Patent number: 4575389Abstract: The invention relates to bending of glass plates moving in a horizontal position, under the effect of their own weight, with a device comprising a shaping bed made of rotating shaping elements whose surfaces in contact with the glass plates, as they advance, define increasingly curved generatrices, these shaping elements being carried by a frame that can be inclined by pivoting around a transverse axis located at its upstream end. The frame is mounted on pivoting axes (XX', YY', ZZ') that are adjustable in height. Particular zones of the glass plates can be kept at a constant level during bending, which improves the optical quality of the glass plates thus bent.Type: GrantFiled: November 9, 1984Date of Patent: March 11, 1986Assignee: Saint-Gobain VitrageInventors: Friedrich Halberschmidt, Josef Audi, Gerhard Schubert

Patent number: 4528780Abstract: A process and apparatus for the control of the path of the grinding tool of an all-around edge grinding machine supporting a glass pane for movement about a rotational axis. The grinding tool is positively guided into contact with the edge of the glass pane as controlled by the contour of the glass pane. A scanning roller, also guided into contact with the edge of the glass panel provides the control heretofore described. Both the grinding head and scanning roller are movable in a direction toward the rotational axis of the glass pane. Path signals determined by the scanning roller are stored in a sliding register, and delayed at its output for a period of time required for movement of the glass pane through an angle which corresponds to the rotational angle (.alpha.,.beta.) between the point of contact of the scanning roller and the point of contact of the grinding tool on the edge of the glass pane. The path signals from the sliding register are used in position controlling the grinding tool.Type: GrantFiled: January 19, 1983Date of Patent: July 16, 1985Assignee: Saint-Gobain VitrageInventors: Friedrich Halberschmidt, Heinz-Josef Reinmold, Josef Audi
