FIELD: weapons.

SUBSTANCE: invention relates to small arms automatic weapons, namely to loose cartridge belt for automatic weapons, mainly for machine guns. Loose cartridge belt for automatic weapons consists of successively arranged and hinged links made of polymer materials, wherein each link consists of three cartridge grippers connected to each other by a bridge, the front and rear grips are located coaxially at a distance exceeding the width of the middle grip, on one side of the bridge, and the middle gripper is located between the front and rear grips on the opposite side of the bridge, forming a hinged connection of the links by placing the cartridge in the front and rear grips of one link and the middle cartridge gripper of the next link. Inner surface of the middle grip is made in the form of two pairs of coaxial conical surfaces and two flat surfaces, which allows the cartridge to change the angular position in the middle grip in the plane of symmetry of the link. Inner surfaces of the rear and front grippers are made in the form of a cylindrical or conical surface, the guide of which is formed by a circle or identical arcs connected by their ends, their bulges directed outward from the axis of rotary symmetry of the gripper.

EFFECT: improved operational properties due to increased reliability of cartridge retention in link and mobility of hinged connection of links.
