Abstract
A rotary-type tabletting machine with lubricant spraying means, wherein a turn table has plural penetrated holes comprising dies provided at fixed intervals in a ring-like arrangement, each hole is provided with a pair of punches above and under the hole, each pair of punches is rotated together with the turn table and execute piston operation so that tablets are continuously produced by compressing pharmaceutical material filled in the die. The rotary-type tabletting machine is provided with a spraying chamber with an upper open end for inserting an upper punch and enclosing the die when the turn table moves to a rotation position which is after a rotation position where a molded table is discharged and before a rotation position where pharmaceutical material is filled in the die. A spray connected with the spraying chamber sprays lubricant in the spraying chamber, and pulsating air generating means connected with the spraying chamber diffuses. The lubricant sprayed in the spraying chamber.
