PURPOSE:To obtain a titled device for making an equipment inexpensive by putting plural supply bobbins into a pressure vessel provided with plural dies, and simultaneously, executing a continuous hydraulic pressure wire drawing. CONSTITUTION:Plural supply bobbins 4d' are put into the inside 4c' of a pressure vessel 4 provided with plural dies 4b', a hydraulic pressure of the inside 4c' of the vessel is applied by a pressure increasing machine 1, and simultaneously, plural wires are brought to a continuous hydraulic pressure drawing. In this case, it is necessary that each wire drawing is executed under the same hydraulic pressure condition, but the equipment becomes inexpensive, and also a mass production is executed.
