ABSTRACT:
A stop assembly for positioning glass sheets that are pressed between upper and lower shaping molds. The stop member is pivoted into a sheet engaging position as the sheet is heated and conveyed onto a gas hearth. As a lifting ring which surrounds the gas hearth moves vertically, lifting the sheet off the gas hearth and towards the upper mold face, the stop assembly rotates to a position outside the pressing surface of the upper and lower molds.
