Publication number: 20220177346Abstract: Methods of making a laminated glazing having reduced optical distortion when installed in a vehicle are described. The laminated glazing has first and second sheets of glazing material each separately shaped between a pair of shaping members that are then laminated together. The position for bending the first sheet of glazing material may be deliberately offset from the position for bending the second sheet of glazing material. During the lamination step, the first sheet of glazing material may be displaced relative to the second sheet of glazing material by a lateral and/or longitudinal positional displacement. The first and/or second sheet of glazing material may have been cut such that after lamination at least a portion of the peripheral edges thereof are aligned. Apparatus for shaping a sheet of glazing material for carrying out the aforementioned methods is also described, as is a resulting laminated glazing.Type: ApplicationFiled: February 22, 2022Publication date: June 9, 2022Applicant: Pilkington Group LimitedInventors: Peter PAULUS, Joachim PILZ

Patent number: 8448466Abstract: The glass sheets (2) of an asymmetric glass-sheet pair, which is intended for the production of laminated glass, are preheated in a preheating furnace (1) and then undergo a press-bending process in a press-bending station (4). By means of a temperature measuring point (11) arranged at the exit of the press-bending station, it is ensured that the glass sheets exhibit a uniform bending behavior, in order to guarantee identical restoring forces during cooling. The temperature measuring point (11) is connected to a control device (16), which causes an intermediate cooling of the glass sheet heating more rapidly by means of an intermediate cooling installation (12, 13) in the pre-heating furnace and/or lengthens its dwell time in the press-bending station (4) by means of a timing control element (15).Type: GrantFiled: March 22, 2004Date of Patent: May 28, 2013Assignee: Pilkington Automotive Deutschland GmbHInventors: Dieter Funk, Joachim Pilz, Peter Michels

Patent number: 7866186Abstract: The gas cushion serves to support a preheated glass sheet and is produced by a chamber, which is connected to a source (21) of compressed gas. The upper wall (10) of the chamber is adapted to the shape of the glass sheet and has a plurality of apertures for the passage of gas in the form of nozzles (14), which comprise an entry bore (22) and, following thereupon, a progressively widening exit hole (16) with a nozzle exit area (15). The upper wall (10) of the chamber has a greater degree of perforation (sum of the nozzle exit areas (15) in relation to the total area of the respective zone) in its edge zone (12, 13) than in its central zone (11). The nozzles ensure that no jet marks can arise. The gas of the gas cushion can also flow out undisturbed at the side, so that no cooling edges are present and the occurrence of cooling shadows is accordingly avoided.Type: GrantFiled: March 22, 2004Date of Patent: January 11, 2011Assignee: Pilkington Automotive Deutschland GmbHInventors: Dieter Funk, Joachim Pilz, Peter Michels

Patent number: 7866187Abstract: A press bending station includes an annular mold (5) and a full-face mold (6). Holes (10), selectively connected to a negative pressure source, are placed in portions of the full-face mold (6) that are determined by the configuration of the annular mold when the annular mold comes into contact with a heated glass sheet (2) during the press bending process. The sheet (2) is drawn by negative pressure through the holes (10) towards the full-face mold (6) and thus acquires its shape. Positive pressure may be selectively applied to the holes (10) to release the sheet (2). According to the invention, at least some of the holes (10) are arranged in at least one groove (11) formed in the mold face of the full-face mold. The grooves (11) according to the invention accelerate considerably the removal by negative pressure of the air between the molding face of the full-face mold (6) and the glass sheet (2) to be bent and thus improve the press bending process.Type: GrantFiled: September 24, 2003Date of Patent: January 11, 2011Assignees: Pilkington North America, Inc., Pilkington Automotive Deutschland GmbHInventors: Robert J.
