Abstract (en)
[origin: ES8501113A1] To feed cartridges from a drum-type or drum magazine to a firing weapon a first conveyor is required to push the cartridges out from the drum-type magazine in which the cartridges are arranged in a number of rows. A second conveyor feeds the cartridges which have been ejected from the drum-type magazine to the firing weapon. At high firing rates as required in multi-barrel guns or weapon systems difficulties can occur in the transfer of the cartridges from the first conveyor to the second conveyor and during the acceleration of the rows of cartridges in the drum-type magazine. According to the invention return or reverse movement blocking devices are arranged between the two conveyors and the first conveyor comprises a screw or worm conveyor having a first turn of the thread which is of smaller pitch than the remaining turns of the thread to facilitate the acceleration of the rows of the cartridges which are initially at standstill in the drum-type magazine.
