Abstract
An end cap (18) for use with a conveyor roll (12) of the thermally low expansive ceramic type used to convey hot glass sheets includes a metal sleeve (20) that receives an end (16) of the roll to provide rotational support and/or driving and also includes a retention spring (22) interposed between and engaged with both the roll end and the sleeve in order to retain the sleeve on the roll. The retention spring (22) preferably includes a plurality of leaf springs (44) that are sufficiently deflected at room temperature so as to remain partially deflected upon heating in order to provide the end cap retention.
