Abstract

PURPOSE: To improve the degree of orientation and transparency of a high polymer material, by drawing the material under a hydrostatic pressure.
CONSTITUTION: The oil fed from the tank 5 is pressurized by the compressor 4 and sent to the pressure buffers 7a and 7b to close the valves V1 and V4. The hydraulic pressure is determined by the manganin wires 8a and 8b to control the valves V2 and V3 for feeding the oil. The pressure of the top high-pressure chamber 10 is set to X; the pressure of the bottom chamber 11, to Y (Y<X). The chuck 12b is lowered according to the pressure difference (X-Y) while holding the sample 19. The displacement is detected by the differential transformer 18 to operate in response to the magnetic core 17. According to the method, the differential pressure, i.e. drawing tension, will not lower by the drawing, and the operation can be performed simply and easily.
