Abstract
The invention relates to a flow barrier in the annealing section of a glass tempering apparatus, said annealing section being provided with glass sheet supporting rollers (7) and cooling air blow boxes (1, 3) are disposed above and below a glass sheet, in addition to which there are, above the glass sheets, 'false rolls' (8) in the form of a downward open trough, extending crosswise to the traveling direction of said glass sheets. The purpose of 'false rolls' (8) is to increase a pressure applied to the top surface of a glass sheet in order to reduce the risk of a glass sheet becoming afloat. A flow along the trough, which increases towards the ends of the trough, results in a non-uniform tempering. The flow is cut off by fitting the trough with partitions (9) spaced from each other.
