A feeding mechanism for ball bullets from a bin to a holder. The mechanism contains a bin 1 and additional reservoir 2 which in a lower part communicate. A vibrator 3 is placed in the lower part of the bin 1 and the additional reservoir 2. The vibrator 3 is formed of two plates 4 and 5 of L-shape that oscillate on the axis 6 due to spring 7 and cam 8, which is rotated by the electric drive 9. A feeding screw mechanism is disposed in the lower part of the bin 1 and the additional reservoir 2, the mechanism comprising a screw 10 with a helical spring. The base 12 is connected to cam 8 through a friction coupling 13. The cam 8 gains rotation from the electric drive 9 through the gearing 14. The bin 1 with additional reservoir 2 communicates with the holder 16 through the channel 15.
