STONE ROLLER FOR PAPER MAKING MACHINES ABSTRACT OF THE DISCLOSURE A stone roller for paper making machines hav- ing a tubular body made of stone with an axial bore- hole. A plurality of tie-rods extend along the inner wall of the borehole and parallel to its axis. The tie-rods are used to clamp plates against the two ends of the roll body. A corepiece, sealingly connected to both clamping plates, is disposed within the borehole, creating an annular space sealed off from the central region of the bore. The tie-rods extend through the annular space. The space is filled with a plastic which is introduced in liquid form at room temperature and then hardened. The hardened plastic prevents the tie-rods from vibrating and shields them from corrosive elements.
