The device has a drive wheel for pushing thrust units (2) along a conveyor path, where the wheel engages with a roller (3) and a spacer body (4) of each thrust unit. Each of the spacer bodies arranges the thrust units at a distance from each other, where the thrust units extend in a conveying direction from one end to another end. Each thrust unit is movably supported in an area of the former end, and is supported in an area of the latter end on an adjacent thrust unit. The thrust units are loaded with respect to each other with a compressive load but not with a tensile load.
