Abstract
A process and apparatus for conveying formed, heated glass sheets from a glass forming station, through a glass tempering station, to a lehr, utilizes a shuttle ring conforming in outline and elevation to the marginal edges of the glass sheet. The shuttle ring receives the glass sheet from the lower shaping mold, by the relative downward vertical movement of the lower shaping mold away from the upper shaping mold. The glass sheet thus deposited on and supported by the shuttle ring is transported through the tempering station to the lehr.
