Abstract:
A belt guidance unit for centring a conveyor belt, which during operation is susceptible to lateral displacement from a longitudinal neutral position, which belt extends over a guide roller mounted substantially across the belt's direction of travel, which guide roller is rotatably mounted in a holder about an axis substantially across the belt's direction of travel, which holder for the guide roller is rotatably mounted on a base about a substantially perpendicularly extending axis relative to the conveyor belt's direction of travel, characterised in that between the holder for the guide roller and the base there is mounted a rotationally elastic element, which in a neutral position gives the holder for the guide roller a rotational displacement to a first side relative to the conveyor belt's direction of travel, which rotationally elastic element is tightened when the holder is brought towards a neutral position relative to the conveyor belt's direction of travel, and that in connection with the holder or the guide roller; at a distance from the holder's rotational axis about the base, there is mounted at least one arm with a guide device at a distance from the holder, which guide device is mounted at the conveyor belt's lateral edge.
