    • PURPOSE:To enable the casting of a cast body having excellent and extra precision in a large scaled product by forming high pressure difference between a melting chamber and a casting chamber. CONSTITUTION:After replacing the atmospheres of the melting chamber 10 and the casting chamber 11 with inert gas, the high pressure difference between the melting chamber 10 and the casting chamber 11 is formed prior to the pouring of molten metal. At this time, the inert gas is exhausted outside the system from the melting chamber 10, a porous mold 7 and the casting chamber 11 through a connecting hole 16 with a solenoid selector 17. Then, at the time of executing the casting, an annular airtight level in a conical mold receiving base 1 arranged in the casting chamber 11 is positioned at the upper edge of the cast body to form the high pressure difference between the melting chamber 10 and the casting chamber 11. The boundary zone between a runner in the mold and a cavity molding body is positioned at the annular air-tight level formed in a circular groove 3 in the mold receiving base 1. Thus the mold receiving base 1 is formed in a conical shape and plural steps of the circular grooves 3-1, 3-2 are engraved in the inner periphery 2. By this constitution, the high airtightness of the melting chamber and the casting chamber can be obtd.

    • PURPOSE:To shorten the cycle time of work by a method wherein a first base arm and second base arm for a frame body fundamental shaft are integrally turned and elevated, and the revolving center of an outer peripheral paper roll arm and outer peripheral paper clamp arm is adjusted to meet the center of a coil, and speeds of the outer peripheral paper clamp arm and a cradle roll are synchronized. CONSTITUTION:A metal coil C is placed on cradle rolls 42-1, 42-2 which are provided in parallel. Also, the cradle rolls 42-1, 42-2 are driven in the same direction. On a frame body 50, a fundamental shaft is provided in parallel with the cradle rolls, and the fundamental shaft has a base 51 and is able to rotate. A first base arm 52 and second base arm are projected from the fundamental shaft, and an outer peripheral paper roll arm is axially supported by the first base arm 52, and an outer peripheral paper clamp arm is axially supported by the second base arm. After the revolving center of the outer peripheral paper roll arm and outer peripheral paper clamp arm has been positioned at the center of the coil by the rotation and elevation of the base arms, when an outer peripheral paper is wrapped around the metal coil C, a roll of the outer peripheral paper is made to revolve around the coil while giving self-revolving. After the outer peripheral paper has been wound to its rearend, pressure is added in the roll to expand a cushioning chamber, and a tape is pressed to strengthen the adhesion.
