Abstract : The patent describes a press and interchangeable barrel for extruding explosive and plastic materials in continuous strands of predetermined cross-section. The barrel, which contains the raw material to be worked upon, is held at a uniform temperature by a coil. A counter flow of heating or cooling fluid is provided in the coil by wrapping it around the barrel such that it turns back upon itself. This provision of counter flow, in the coil, permits precise temperature to be held. The mass of the barrel wall also aids in maintaining a uniform barrel temperature.
