Beschreibung
Zusammenfassung:	The invention relates to the field of combustible ammunition and relates chiefly to the manufacture of bottoms or covers for combustible cases. According to the invention, a combustible article is manufactured by pressing in a die 10 at least one sheet 21 of combustible paper containing nitrocellulose and having the shape of a disc, by virtue of a rigid movable punch 20 exerting a compressive force on a deformable flexible punch 22 arranged inside the said die 10 between the sheets 21 and the said movable punch 20. The flexible punch 22 is in the shape of a substantially cylindrical thick disc, consists of neoprene or a silicone resin and has a hardness of between 55 and 65 Shore at 20 DEG C. The pressing operation is accompanied by a thermoforming operation carried out at approximately 115 DEG C. The process is particularly suitable for the production of bottoms of combustible cases bearing studs or grooves on their side faces.
