Abstract

A cartridge belt for automatic firearms includes a plastic strip having transverse, spaced grooves for receiving the cartridges, the central transverse portions of the areas of the belt between the grooves being molecularly oriented to permit hinging of the belt without deformation of adjacent portions of the belt so as to improve flexibility of the belt.

Claims

1. A cartridge belt for use with automatic firearms comprising a belt composed essentially of a relatively stiff high density plastic material provided with a plurality of transverse, Substantially semicylindrical, spaced grooves therein for receiving cartridges, the central transverse portions of said belt between adjacent grooves being molecularly oriented to permit transverse hinging of the belt at the central portions without deforming adjacent portions of the belt, and means for retaining cartridges in said grooves.

2. A cartridge belt as claimed in claim 1 wherein the high density plastic material is selected from the group consisting of polyethylene, polypropylene, and polyvinyl chloride.

3. A cartridge belt as claimed in claim 1 wherein the means for retaining cartridges in said grooves comprises a relatively thin strip of transversely oriented plastic material passing over the cartridges in said grooves and sealed to the said belt between adjacent transverse grooves.
