Abstract
In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The spring elements project outward from the annular hub such that an end of each spring element is positioned radially outward from a base of each spring element and is circumferentially offset relative to the base of each spring element.
