    Abstract: A plurality of propellant cartridges are serially connected with each other to form a band that may be rolled up for utilization in a commercial device, such as a riveting gun. The cartridges may be attached to a band by extending their electrical leads through the band for clamping the cartridges to the band, bonding the cartridges to the band, or providing the cartridges with a force fit in recesses of the band, for example. Also, propellant carrying cases may be formed in pairs for serial connection with primer carrying bases formed in pairs. Also, preformed lengths of cartridge-carrying bands may be connected serially with each other by means of connectors.
