Claim 6:
7. A device for annealing a glass pane, the device comprising:
a plurality of rollers on which the glass pane can be transported horizontally;
a plurality of first cooling air feeds running parallel to axes of the rollers, from which cooling air can be guided onto an underside of the glass pane, each of the first cooling air feeds being arranged between two of the rollers;
a plurality of second cooling air feeds running parallel to the axes of the rollers from which cooling air can be guided onto a top surface of the glass pane, each of the second cooling air feeds being arranged above the glass pane, and each of the first and second cooling air feeds extending across a width of the glass pane; and
a plurality of flat walls running parallel to the second cooling air feeds with a thickness of the flat wall is less than a diameter of the rollers, each of the second cooling air feeds being arranged between two of the flat walls,
wherein each of the flat walls extends to a distance of no more than 10 mm from the glass pane and each of the first and second cooling air feeds is formed as a nozzle having a slight with the nozzle becoming increasingly narrow along its entire length in the direction toward the glass pane so as to form a substantially “V”-shaped flow channel extending across the width of the glass pane that continuously tapers along its entire length such that the cooling air from each of the first cooling air feeds strikes the underside of the glass pane, is deflected outward to both sides toward the rollers, and strikes the rollers and is diverted downward such that return of this cooling air deflected from the glass pane occurs between the rollers and outer sides of the flow channel of the first cooling air feed, and the cooling air from each of the second cooling air feeds strikes the top surface of the glass pane, is deflected outward to both sides toward the flat walls, strikes the flat walls, and is deflected upward such that return of this cooling air deflected from the glass pane occurs between the flat walls and outer sides of the continuous tapering flow channel of the second cooling air feed.
