Abstract: A conveyor belt is provided with at least one guide rim, wherein the guide rim extends in a longitudinal direction of the conveyor belt, such that it enables guiding of the belt along a lateral guide surface on an outer periphery of a roll or the like by which the direction of the belt is changed and by which the belt is subjected to a predetermined bending. The guide rim has a contact surface that is in contact with the conveyor belt. In a position in which the belt is not subjected to any bending in the longitudinal direction thereof, as seen in a cross section cross wise to the longitudinal direction of the guide rim, the guide rim presents residual stresses (?1, ?2) including an induced tensile stress in opposite lateral regions of the contact surface and an induced compressive stress in a region between the lateral regions.
