PURPOSE:To certainly perform a re-compression process in good accuracy within a short time without using a complicated conveying mechanism, by charging the sintered body sent in from a chuter to the holding part notched in an L-shape provided to the upper part of the effective diameter part of a die through the pusher of a cylinder. CONSTITUTION:The sintered body 1 sent in from a chuter 3 is pushed forward by a pusher 4 to be charged in the L-shaped holding part 2b of a die 2 whereupon pressed in the effective diameter part 2a from the up-and-down direction by a lower punch 7 and an upper punch 8. Subsequently, when a cylinder 5 is turned OFF and the pusher 4 is returned to the original position, the punches 7, 8 are raised to pull out the corrected sintered body while the next sintered body 1 is sent in front of the pusher 4. Thereafter, the sintered body 1 after correction is discharged by a separate discharge mechanism and, at the same time, the next sintered body 1 is pressed to the side surface of the lower punch 7 by the pusher 4 and charged in the holding part 2b by the falling of the punch 7.
