<p>A conveyor belt roller (1) is provided of generally cylindrical shape and having its own outer surface and a separate contact surface (2) spaced radially outwards thereof for operative engagement by a conveyor belt in association with which the roller is to be used. The contact surface is a composite surface made up of outwardly directed surfaces of a multitude of replaceable contact elements (3, 17, 24, 25, 29, 30, 36) held in their operative relationship relative to the surface of the roller by mechanical attachment means (7, 12, 22, 23, 26, 33, 35) that physically engage the elements to maintain them in cooperating relationship with respect to the roller. The contact elements are in contact with, or in close proximity to, the outer surface such that the contact elements are urged into contact with such outer surface in consequence of contact between a conveyor belt and the outwardly directed surfaces of the contact elements.</p> |
