When the molding of the compression body 12 is completed, the pressure piston 6 retracts to the standby position, the introduction port 4 is opened, and the introduction of the chips is restarted. Then, when the amount of chips introduced into the cylinder 5 reaches the set amount, the pressure pinton 6 advances to the pressure position, and the chips are pressed against the rear surface of the compression body 12. A new compressed body is continuously molded.

The molding of the compression body 12 is repeated as described above, and when it is confirmed that the preset number of the compression bodies 12 are formed in the compression body detection unit 13, the opening / closing lid 9 is opened.
