Abstract
Förfarande för värmestärkning eller härdning av glasskivor i en glaslastning, som innehåller flera glasskivor (G1, G2), där glasskivorna uppvärms i en ugn (1) till en härdningstemperatur och flyttas med en glaslastningsflytthastighet (W) ut ur ugnen (1) in i en härdningsenhet (2), där den egentliga härdningsnedkylningen utförs genom att blåsa kylluft på glasskivornas (G1, G2) båda ytor. Med en mellan ugnen (1) och härdningsnedkylningsenheten (2) belägen förblåsningsenhet (8), som i tvärriktning med avseende på glasets rörelse är indelad i förblåsningszoner (6.1 – 6.i, 6b.1 – 6b.i), blåses trycksatt luft på den yta i glasskivans (G1, G2) fram- och bakända, där ändan önskas rätas ut i riktning med ytans normal för att minska ändböjning.
