Unsupported, compressed propellant charge elements of nitrocellulose grains, as well as propellant charges produced from these propellant charge elements are produced by coating the grains with an acrylate resin and shaping the grains into cylindrical elements. The novel propellant charge elements are manufactured practically without concomitant use of binders or adhesives; they have a cylindrical configuration and contain a coaxial, continuous bore. These elements are suitable as building blocks for propellant charges in ammunition, e.g., for machinegun...
Unsupported, compressed propellant charge elements of nitrocellulose powder grains, coated with a resin layer, characterized in that: (a) the nitrocellulose powder grains are coated with an acrylate resin layer constituting 0.5-6% by weight of the grains, (b) compressing takes place with a pressure force of between 500 and 1,500 kg/cm2 [49,000 N/m2 to 150,000 N/m2]and without concomitant use of an additional adhesive, and (c) the thus-obtained element is fashioned as a cylinder having a continuous axial bore, the height of which is between 70 and 200% of...
