For steering a conveyor belt (11) and centring the same relative to the intended path of travel of the belt, use is made of a belt position detecting means (22, 23) and belt readjusting means (24). The belt readjusting means (24) is a belt support roller (24) which is adapted to engage and roll against the belt and which is pivotable relative to the belt. According to the invention, the belt position detecting means (22, 23) and the belt support roller (24) are arranged on a roller cradle (21) which is connected with a frame (29) by means of inclined links (30) for pivoting and setting the belt support roller (24) in a pivoting position, in which the belt support roller by engaging the belt exerts a readjustment force thereon.
