Belt-position sensing structure (30) and belt readjustment apparatus (36) are used to steer a conveyor belt (11)) and to center said belt relative to the intended path of travel of the belt. The belt readjustment apparatus (36) is a belt-support roller (36) intended to engage the belt and to roll against the latter and being pivotal in the principal plane of the belt. The belt-position sensing structure (30) is connected to the belt-support roller (36) via a linkage system (27, 34) for pivoting and setting the belt-support roller in a pivotal position in which said belt-support roller, by engaging the belt, exerts a readjustment force on the belt. |
