Abstract
A ceramic roll for transporting glass sheets for thermal treatment is drivingly connected to a drive shaft through a metal end cap using one or more circumferentially expandable, radially compressible, split metal rings that wedge into the circumferential space between the end portion of the roll and the inner surface of the metal end cap. The metal end cap is of uniform diameter throughout its axial length that surrounds the end of the roll. This construction is cheaper to fabricate than prior art metal end cap constructions of more complicated structure.
