When the glass tempering furnace makes reverse bending, it uses the T plates engaged with each other, stop blocks, and drive device in the special variable curvature mechanism to control the roller curvature of the soft shaft. In the meantime, by exerting an upward force on the middle of the arcing mechanism to shape the chiller, it will avoid the coated surface or inked surface to get in contact with the rollers and hence meet users’ needs for high-quality reversely bent tempered glass.
