Method for series production and introducing an explosive charge into containers for explosive bodies

The necessary quantity component of detonating charge, containing initiating explosive, is supplied to each individual container. The detonating charge is produced at a rate which corresponds in practice to that of its supply to the individual containers so that, in practice, no excess detonating charge is formed. The production of the detonating charge comprises the formation of at least a part of the initiating explosive by chemical reaction between two or more relatively insensitive components in the presence of a fluid reaction medium. The method makes possible continuous and automated incorporation of detonating charges into rim-firing cartridges and into detonating capsules for centre-firing cartridges while avoiding the risk element, which was previously extremely high.
