13. A conveyor belt system comprising:
a conveyor belt;
a first roller;
a second roller, wherein the conveyor belt extends between the first roller and the second roller so that the conveyor belt has a transport side and a return side; and
a frame for positioning the conveyor belt, wherein the frame has at least two upright walls at a position of opposite transverse ends, the two upright walls being formed such that, at a position of the return side, the return side falls within the two upright walls and that, at a position of the transport side, the transport side protrudes to a position outside the upright walls on either side,
wherein the conveyor belt has a central zone which is demarcated by two upright ribs,
wherein the frame has, at least at the position of the transport side and at the position of the two transverse ends, a groove in which an upright rib is in each case received,
wherein each upright rib is situated at a distance from an edge of the conveyor belt so that two further zones of the conveyor belt are situated outside the ribs, and
wherein the conveyor belt extends with each of the two further zones through an elongate opening of the upright wall to the position outside the upright walls.
