Patent number: 11261120Abstract: A glass bending device is presented. The glass bending device includes a bending chamber, a tool for holding at least one glass pane by means of a suction effect, including a downward-directed frame-like, convex contact surface and a cover with a peripheral air-guiding plate surrounding the contact surface at least in regions. The tool is suitable for sweeping the edge of the glass pane at least in sections with an air flow and thereby pressing the glass pane against the contact surface. The glass bending device further includes a fan, which is connected to the bending chamber via a feed line and a return line and is suitable for extracting air from the bending chamber via the tool and the feed line to produce the air flow and for returning air back into the bending chamber via the return line. The return line is connected to the bending chamber above the tool.Type: GrantFiled: August 15, 2016Date of Patent: March 1, 2022Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Michael Balduin, Herbert Radermacher, Guenther Schall

Patent number: 9771297Abstract: A method and device for bending superposed sheets of glass. The sheets are picked up by a top form furnished with a suction creating an upward airflow blowing over the rim of the sheets, the suction being sufficient to lift and hold the superposed sheets against the top form, then the sheets are pressed between the top form and a full surface solid concave bottom form furnished with openings, the pressing beginning conducted while the suction is not yet finished or is finishing, then the superposed sheets are formed, by suction of the main face of the bottom sheet through the openings of the bottom concave mold, the forming by suction beginning while the pressing is not yet finished, and then the sheets are cooled. Windshields free of optical defects may thus be produced.Type: GrantFiled: April 30, 2014Date of Patent: September 26, 2017Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Michael Balduin, Michael Labrot, Karl-Josef Ollfisch, Herbert Radermacher, Guenther Schall

Patent number: 8146387Abstract: A process and system for bending glass sheets heated to their softening point. The glass sheets are laid on a concave bending frame and prebent by gravity. The prebent glass sheets are transferred to a transfer former with a concave forming surface, the transfer former being moved up through the concave bending frame, the perimeter of which is larger, and thus picking up the glass sheets. The transfer former is positioned so that in vertical projection it overlies a final bending former in the form of a frame with a concave forming surface. The transfer former is moved up through the larger-diameter final bending former, the glass sheets being laid on the final bending former. The glass sheets are bent into their final shape, and at the end of the bending operation, the glass sheets in their final shape are transferred from the final bending former to a transport system and cooled.Type: GrantFiled: March 26, 2004Date of Patent: April 3, 2012Assignee: Saint-Gobain Glass FranceInventors: Karl-Josef Ollfisch, Thomas Meissen, Herbert Radermacher, Michael Labrot
