1. A machine for attaching ammunitions intended to form a chain or strip with links of ammunitions or cartridges, including an ogive, a cartridge casing, and a cup that are essentially cylindrical, attached by links articulated to one another, each link comprising a first part attached to a second part, the first and second parts being offset relative to one another, the second part including a central loop or handle relative to a height of the link, defining an approximately semi-cylindrical opening, sized to be adjusted on the cartridge casing of a cartridge of given caliber, the first part including two central loops or handles but located, heightwise, respectively on either side of the central loop, the machine comprising:
a first guideway configured to successively introduce the links detached from one another and guide the links under an effect of gravity;
a second guideway configured to successively introduce the cartridges and guide the cartridges under the effect of gravity;
a moving mechanism comprising a first shaft, a second shaft, and a third shaft, the first, second, and third shafts being mounted parallel to one another and coupled by gears, the moving mechanism being configured to be set in motion by rotation of the third shaft, which is configured to drive, in a continuous movement, rotation of the first shaft in a counterclockwise direction and rotation of the second shaft in a clockwise direction, or vice versa, the first shaft including at least two gripping wheels each having slots regularly spaced apart and with a circular shape so as to drive the casings of the cartridges, the second shaft including at least two gripping wheels having slots regularly spaced apart so as to drive the cup or a rear part of the links, such that, when the moving mechanism is set in motion, each cartridge is presented by the rotation of the first shaft synchronously with the link presented by the rotation of the second shaft and is clipped transversely in the link; and
an electric motor or a manual crank configured to set the third shaft in rotation.
