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.
