Abstract

For producing propellant charge granular material several small diameter pellant charge strands are continuously extruded, individually placed on a support behind the extruder and conveyed over a setting zone. The strands are subsequently supplied on a sloping zone to a cutting plate with a number of guide holes corresponding to the number of strands. On passing out of the guide holes the strands are cut to the desired length by cutting blades rotating being the cutting plate.
