A process for the preparation of (6) Tablet pressing surface of the lower end of the upper punch and (9a), by compression molding the powder die of (1) in the pressing surface of the upper end of the lower punch by a (11a), each of the upper and lower forming groove of the concave curved surface shape and being connected integrally (9a, 11a) on the pressing surface (2a) is formed on the inner peripheral surface of the die holes (2), the mortar in the boundary bottom molding groove of (2a) is divided and a discrete piece of the upper (7) split pieces in the lower (8), or one of the upper and on the other hand forming groove (9a, 11a) the pressing surfaces (2a, the final fixed side punch is a punch side after being fixed to the compression molding position to be connected integrally to), then compression molded into (6) tablets can be moved to the compression molding position the final compression side punch is a punch on the other side, the tablets (6) In carrying retrieve were separated and divided pieces of the upper and lower (7, 8), as well as remove the tablet from the final fixed-side split piece split piece of the final fixed-side punch side, which is the (7,8), remove the tablet from the final fixed-side punch , then, I remove the tablet from the final compression side split piece split piece of final compression side punch side, which is the (7,8).上杵の下端の押圧面(9a)と,下杵の上端の押圧面(11a)とによって臼(1)内の粉体を圧縮成形して錠剤(6)を製造する方法において,上下の各押圧面(9a,11a)に一体的に連接される凹曲面状の成形溝(2a)が臼孔(2)の内周面に形成され,該成形溝(2a)の底部を境に臼が上側の分割片(7)と下側の分割片(8)とに分割形成され,上下の何れか一方側の杵である最終固定側杵を,押圧面(9a,11a)が成形溝(2a)に一体的に連接される圧縮成形位置に固定させた後,他方側の杵である最終圧縮側杵を圧縮成形位置に移動させて錠剤(6)に圧縮成形し,この錠剤(6)を上下の分割片(7,8)を分離させて取出すにあたって,最終固定側杵側の分割片(7,8)である最終固定側分割片から錠剤を外すとともに,最終固定側杵から錠剤を外し,その後,最終圧縮側杵側の分割片(7,8)である最終圧縮側分割片から錠剤を外す。
