PURPOSE:To press objects to be pressed easily and uniformly with a large force by uniformly pressing objects to be pressed through the front ends of several pistons, which are projected on the front faces. CONSTITUTION:Pressing boards 1 are fitted between the spacers 28, 29 of arbor shafts 21, 22, and the rear faces of the pressing boards 1 are brought in contact with the spacers 28 at the back side. And, the front end face of each piston 4, which is projected on the front face of the pressing board 1, is brought in contact with the spacer 29 on the front side. Threaded shafts are screwingly advanced toward pressing chambers by means of a rotating tool and spindles are screwingly advanced toward the bottom sides of the pressing chambers, pressing the pistons against the bottom sides of the pressing chambers. Thereby, each cutter 26 interposed between spacers 25, 25 and between spacers 25, 29 is pressed and clamped from the both sides. |
