ABSTRACT:
An apparatus for conveying sealed insulating glass panes (1) includes a conveying device (3, 14) associated, in the zone of the end (10) on the inlet side and the end (11) on the outlet side, with recorders (12), preferably those with respectively two TV cameras, producing images of the corners (4, 5 , 6 , 7 ) of the insulating glass pane (1), these images being displayed as stationary images on a monitor (41) until the subsequent insulating glass pane (1) arrives. In order to improve the quality of the images, illuminating devices (15) are associated with the recorders (12), these devices being activated only when the recorders (12) are in operation. Based on the images of the corners (4 and 5) of the insulating glass pane (1) produced by the recorders (12) and displayed on the monitor (41), the quality of the seal (20) in the zone of the corners (4, 5, 6, 7) can be evaluated even without lifting out and turning of insulating glass panes (1).
