ABSTRACT:
Shaped ammunication for tubular weapons in the form of nitrocellulose-based combustible cartridge cases are continuously produced in a screw extruder from an aqueous suspension, stabilizers, flammable fibrous material, binders and optionally plasticizers being supplied to the suspension. The fibre-like constituents are matted in kneading and pressing zones, accompanied by the simultaneous squeezing out of the water, being shaped to an endless tubular structure, which is then cut to the length of the individual cartridge cases and is optionally also pressed to the desired dimensions and shape. Advantageously use is made of a double shaft screw extruder with kneading and pressing segments, as well as a water outlet, which is provided at its end with a tubular die. A following pressing and cutting to length means is arranged behind the extruder.
