Abstract
Abstract Ammunition belt apparatus for accommodating propellant cartridges including a flexible, coilable belt strip, a plurality of holes extending transversely through the strip and spaced from one another in the longitudinal direction of the strip, and clamping means associated with each of the holes for clamping a cartridge to the strip with portions of the cartridge extending through one of the holes, and with parts of said clamping means being formed separately from the strip and the cartridge. In preferred embodiments, the clamping means includes a tubular casing formed separately from the strip for each of the holes, which tubular casing press-fittingly engages a respective cartridge for holding the cartridge in position on the strip with the casing and a cartridge rim clamping the strip therebetween. Various preferred embodiments include various types of connections for the casings at the strip as well as various materials for the construction of the strip and the casings.
