Abstract: Apparatus for the production of combustible munition containers includes a normally vertical, hollow, water permeable but fiber-impermeable form having a circular cross-section.The form is rotated by a variable speed motor and the interior of the form is maintained under partial vacuum as aqueous suspensions are fed to adjacent axial zones of the form by pipes connected to separate suspension supply tanks so that, after dewatering, the resulting container is non-uniform in composition axially but is uniform in composition axially.

Abstract: A unitary combustible or explosive munitions container of uniform cross-section but of non-uniform linear composition is provided by depositing under suction two different fluid aqueous suspensions of fibrous propellant material and cellulose papermaking fibers on different touching zones of a hollow foraminous shape having an interior under vacuum, thereby forming a water-laid web on said shape, hot pressing the web to desired shape, and trimming the product to size. The process is suitable for the manufacture of cartridge cases and other ammunition containers.
