Abstract

The apparatus serves for inhomogeneous cooling of a flat object with a first main face and a second main face opposite the first main face. The flat object is cooled by a cooling device from the direction of the first main face. On the second main face, a heating device locally acts upon a first partial face in such a way that the flat object is subjected to heat at said first partial face relative to a second partial face adjoining said first partial face in such a way that said first partial face is cooled more slowly in comparison with the second partial face and, during the cooling process, the second main face of the flat object therefore has an inhomogeneous temperature distribution at least in a partial time period of the cooling.
