Apparatus for producing propellant charge powder in the form of strands

摘要

For the continuous or discontinuous production of propellant charge powder in strand form with axially parallel channels having a clearly defined identical diameter and reproducible geometry of the channel arrangement, a press is provided, which has at least one cavity, and which is provided in its strand-forming area with a plurality of needles for shaping the channels, said needles being constructed as open hollow needles and are subject to the action of a fluid with a limited overpressure.
