Abstract: An article of clothing has a main body formed of high-tightness, main-body knitting fabric made of power net. The article of clothing includes front and back support pieces disposed around the waist and having no elasticity in a longitudinal direction thereof. The front support pieces are sewn to a front body at positions inside the left and right ilia of the abdominal pelvis. The back support pieces are sewn to a back body at left and right positions near the sacrum of the pelvis in central hip portions. Side waist pieces disposed between the front and back support pieces are formed by sewing high-tightness, net-like knitting fabric to the main-body knitting fabric at the top edge while leaving the bottom edge unsewn. The article of clothing has a pant-like shape with left and right leg parts that can be tightly fitted around the thighs.

Abstract: A transfer arm holds a plurality of preforms arranged in a single line and simultaneously drops and supplies the preforms downward. A positioning arm has a pair of arm split members split in its widthwise direction. The arm split members have positioning surfaces formed on their contact surfaces to be brought into contact with outer peripheries of the preforms. After the preforms are dropped and supplied from the transfer arm, the arm split members of the positioning arm are opened and closed so that the positioning surfaces are brought into contact with the outer peripheries of the preforms. Thus, the performs are properly positioned.

Abstract: In a press-molding apparatus having upper and lower forming dies (413a, 413b) arranged opposite to each other and upper-die and lower-die heating arrangements for induction-heating the upper and the lower forming dies, the upper-die heating arrangement includes an upper-die induction heating coil (410a), an upper-die power supply (416a), and an upper die temperature controller (417a). The lower-die heating arrangement includes a lower-die induction heating coil (410b), a lower-die power supply 416b, and a lower-die temperature controller (417b). The power supplies are different in oscillation frequency. The upper and the lower forming dies are independently temperature-controlled and heated.

Abstract: In a press-molding apparatus comprising upper and lower dies which are faced with each other and at least one of which is movable as a movable die, and a pair of heating members as upper-die and lower-die heating means (410a and 410b) having heating coils for induction-heating the upper and the lower dies, respectively, the heating member for heating the movable die comprises a first heating coil (410b-1) for heating the movable die in a first position, a second heating coil (410b-2) for heating the movable die in a second position which is apart from the other die than the first position, and a switching unit (420) for selectively supplying the first or the second heating coil with an electric current from a power supply.
