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: 8165382Abstract: Methods of determining the divergence angle between a primary image and a secondary image generated by a glazing are disclosed. In a first method, a glazing is illuminated with a light source and a primary and a secondary image of the light source, generated by the glazing, are captured using an image capture device. The distance between the primary and the secondary image is determined, and the divergence angle determined from this distance. In a second method, the primary and secondary images are viewed on a target marked with a scale indicating the divergence angle. The divergence angle is read from the scale and the positions the primary and secondary image. In this second method, the light source is located at the center of the target. In both methods, the light source comprises at least one light emitting diode. Preferably, the method is used to examine the edge region of a glazing.Type: GrantFiled: May 22, 2007Date of Patent: April 24, 2012Assignees: Pilkington Group Limited, Pilkington Automotive Deutschland GmbHInventors: Ingo Bartsch, Simon Peter Aldred
