PURPOSE:To enable re-compression with highly dimensional accuracy by accurately and rapidly charging a sintered body in a mold, by preliminarily forming the holding part of the sintered body while successively sending the sintered body into the holding part from an oblique chuter. CONSTITUTION:The sintered body 10 fed from an oblique chuter 9 is charged to the holding part 7a of a die 7 and pressed by an upper and a lower punches 4, 6 to correct the dimension thereof to that of the effective diameter part 7b of the die 7. Thereafter, the upper punch 4 is raised with the rising of the lower punch 6 to pull off the sintered body 10 which is, in turn, discharged from the die 7 by a separate discharge apparatus consisting a cam and a link mechanism. Succeedingly, the lower punch 6 is lowered and, at the same time, the sintered body 10 on the chuter 9 is moved over the distance corresponding to one piece by gravity and charged to the holding part 7a of the die 7.
