PROBLEM TO BE SOLVED: To perform pressurization and holding at a dead center for a given time by constituting a slide with a main slide and a sub slide, mounting a mechanical type drive mechanism to the main slide, attaching the sub slide to the base part of the main slide, mounting a movable die to the sub slide, and transmitting the mechanical type drive to the sub slide via a buffer. SOLUTION: It is preferable that a cylinder having a piston rod is used as a buffer. Air of the pressure equivalent to a given pressurizing/holding force is supplied to an air cylinder (buffer) 40. The piston rod 40a is protruded by maximum length. The main slide 10 is made to forward to a fixing bolster 30 by a mechanical type driving mechanism. A sub slide 20 is also forwarded, and the movable die is brought into contact with the fixed die which is attached to the fixing bolster 30, and reaches the dead center. A reaction force is transmitted to the piston rod 40a via the movable die, so as to retreat the rod. While the piston rod 40a is being retreated in the air cylinder 40, a given pressure acts on the die.
