A conveyor with an endless flexible cone-shaped belt which extends over at least two conical rollers between which the belt is kept stretched in a controlled curve path, said belt being provided at its longest edge with a plurality of control elements which stretch the belt under the engagement of the control elements with a first travelling path, which is retained with respect to a frame and extends along the longest edge of the belt in the vicinity of the opposite inner sides of the transport path and the return path of the belt, and in which a second travelling path for the simultaneous engagement of the control elements extends substantially in parallel with and at a distance from the first-mentioned travelling path in the vicinity of the outer sides of the belt facing away from each other, said second travelling path being retained with respect to the frame by means of a plurality of yokes in order to provide free passage for the control elements. This also ensures easy cleaning and service of the control elements as well as a significant reduction in wear and noise over the prior art.
