Abstract
An edge roll apparatus for engaging the marginal edge portion of a hot ribbon of glass, including a body portion and circumferentially positioned teeth. The teeth are shaped to establish at least a 90.degree. angle between the surface of the glass and the leading and outwardly directed edges of the teeth during at least one half of a tooth's engagement path to improve gripping ability.
