摘要

Stress-relieving and/or cooling furnace (10) comprises a housing divided into different cooling zones through which glass (20) passes on rollers (11, 11a). Each roller is driven at a different speed and each has a peripheral speed opposite the previous roller to fit the longitudinal change of the glass during temperature changes in the glass.
