A device for feeding an endless conveyor belt, which along part of its length travels in a helical path, comprises a driving pulley (8) engaging the conveyor belt outside the helical path and between two belt-path sections essentially tangent to the driving pulley. Further, the driving pulley (8) is rotatably mounted in a holder (7), which is so mounted in a stationary frame as to be pivotable about a shaft (17) extending essentially through the one belt-path section transversely of the longitudinal direction thereof.
