In an apparatus for operating a feed device for fibre material, for example, a hopper feeder, there is provided a drivable, endless conveyor belt guided around two rotatable rolls. The conveyor belt is associated at one end, looking in the conveying direction, with an endless, upwardly inclined spiked lattice. Upstream of the other end of conveyor belt, looking in the opposition direction to the conveying direction, there is arranged an endless feed belt (reserve belt) for receiving fibre bales or the like. To convey fibre material to the hopper feeder in a simple manner, without interruption to production, there is arranged between the conveyor belt and the reserve belt 8 a continuously circulating transition belt, and the absence of fibre material on the reserve belt is detectable.
