Abstract
During the infeed of cartridges into a firing weapon cartridges are withdrawn from the sectors of a drum magazine using a first conveyor, and subsequently transferred to a second conveyor which conveys the cartridges to the firing weapon. A return or reverse movement blocking device prevents the cartridges from dropping back into already emptied sectors of the drum magazine. Such return or reverse movement blocking device possesses two pivotable flaps or vane members which may be interconnected and conjointly form a funnel-shaped channel through which the cartridges are displaced by the first conveyor from the drum magazine to the second conveyor.
