Abstract
A method and an equipment for adjusting the cooling air of a glass tempering machine. Cooling air is led by at least one fan (,) to a tempering area (,) for cooling the glass exiting a tempering furnace (,). By means of a closing device (,) the tempering area (,) can be reduced such that a tempering zone with a pressure that can be raised sufficiently high for tempering thin glass can be formed out of the reduced tempering area. In this manner the tempering result becomes very even, and no separate tempering zone is needed even for thin glass.
