Abstract: A joint between an end of a ceramic roll and a metal ferrule compensates for the differences in the thermal expansion properties of the joined materials. A plurality of thermodeformable bimetal elements are positioned in the space between the roll end and the ferrule to expand when the temperature increases to accommodate the greater thermal expansion of the ferrule relative to the roll and to provide a selected coupling strength in the joint at a given operating temperature. The roll is preferably made from a vitreous, fused silica material and is suitable for supporting glass and metal in sheet, strip or plate form at elevated temperatures.
