The present invention provides a means by which chemically or thermally gassed emulsion explosives can be packaged in symmetrical cartridges, such as cylindrical paper packages having crimped ends. After formation, the gassed emulsion explosive is formed into a continuous strip of generally constant width and height. The strip then is passed through a cooling bath to cool the emulsion explosive to a predetermined temperature. A desired length of emulsion then is cut from the cooled strip, and the cut length is wrapped with a paper packaging material to f...
A method of paper-wrapping a gassed emulsion explosive consisting essentially of (a) forming an oil-continuous emulsion at an elevated temperature, (b) incorporating a sensitizing, uniform distribution of gas bubbles into the emulsion to form an emulsion explosive, (c) forcing the emulsion explosive into a continuous strip of generally constant width and height, (d) passing the strip through a cooling bath to cool the emulsion explosive to a predetermined temperature, (e) cutting a desired length of emulsion explosive from the strip, and (f) wrapping the...
