A conveyor belt apparatus comprises a drive unit 1 with a drive roller 3, a pressure roller 5 and a tensioning roller 7 which are bearing-mounted in a frame 9, and a reversing unit 11 with a reversing roller 13 which is connected to a frame 17 by means of a swivel arm 15. The conveyor belt apparatus further includes an endless conveyor belt 19 which is wound around a mobile reel 21 and which can be wound around the drive roller and the reversing roller. In operative position the reversing unit 11 is located distal from the drive unit 1 and the endless conveyor belt 19 is wound around the drive roller 3 and the reversing roller 13. The downstream conveyor belt section 19B then rests upon a base 20 and the upstream conveyor belt section 19A rests upon the downstreamconveyor belt section 19B. The conveyor belt apparatus further includes a plurality of guide elements 23 which each comprise two side guides 25 which are connected to each other via a connecting piece 27.
