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.

Claims

1. Apparatus for the production of combustible munition containers which are non-uniform in composition axially but which are uniform in composition transaxially, which comprises a normally vertical, hollow, water-permeable but fiber-impermeable form having a circular cross section;

controllable means for rotating said form axially;

controllable means for maintaining the interior of said form under partial vaccum;

controllable means connected to a suspension supply means for contacting one axial zone of said form with an aqueous suspension of a mixture of fibrous propellant material, cellulose papermaking fibers and binder material therefor;

controllable means connected to additional suspension supply means for contacting at least an adjoining axial zone of said form with an additional suspension of said materials in a different ratio; and

controllable means for removing liquid from the interior of said form.

2. The apparatus according to claim 1 wherein said form has a water-permeable but fiber-impermeable bottom.

3. The apparatus according to claim 1 wherein said liquid removal means is a suction pipe.

4. The apparatus according to claim 1 wherein said form is within a chamber having orifices only for supply of said suspensions.

5. The apparatus according to claim 4 wherein the interior contours of said chamber parallel the exterior contours of said form.
