METHOD AND UNIT TO HEAT GLASS PLATES Russian patent published in 2009 - IPC C03B29/08 

FIELD: production processes.

SUBSTANCE: in compliance with this invention, glass plates are carried into the oven for heating. In heating, the glass plates vibrate, that is, move back and forward driven by aforesaid rolls. First, the glass plates feed is realised at the 1^st speed v₁, while then, when the glass plate gets fully in the oven, the speed reduces to the 2^nd speed v₂. The 1^st turning point of vibration is realised after reduction in the 2^nd speed v₂ and in over 20 seconds after starting the heating.

EFFECT: reduced amount of defects on glass surface.
