Abstract
The present invention relates to propellent powders in multi-perforated sticks (1) divided by radial slits (7) cutting the peripheral channels (6) of the stick (1) but allowing a continuous cover (8) to remain around its central channel (5). The invention also relates to equipment for obtaining such sticks, comprising:--a drive shaft (17) carrying circular cutting members (18),--a positioning shaft (19) carrying rollers (20) and a thrust shaft (21) carrying rollers (22). The sticks (1) advantageously constitute bundles for artillery ammunition which divide up into elementary particles at the moment of firing.
