The invention relates to a roller ( 21 ) from a refractory material, for example in vitreous silica, for transporting a flat article provided at its end with a new arrangement for rotationally driving it as well as to an assembly of such a roller and its driving device. This roller ( 21 ) comprises an external surface ( 2 ), an inner surface ( 5 ) and two side surfaces ( 12 ), at least one side surface having indentations ( 22 ) parallel to the roller axis ( 3 ) and spaced apart from the external ( 2 ) and inner surface ( 5 ) for receiving rotationally driving pins ( 8 ), it is characterized in that at least one of the indentations ( 22 ) of the roller is provided with a metal jacket ( 24 ). The invention permits to avoid the breakage of the roller around the driving indentations. |
