Claims
- 1. A method for molding powder under compression, by use of a compression molding machine including a horizontally supported turntable provided with bores vertically extending therethrough, each bore being provided with an upper pressure rod and a lower pressure rod respectively positioned above and below the bore, said method comprising the steps of:
- successively filling each bore with a predetermined amount of powder, with an upper end portion of each lower pressure rod being fitted in the corresponding bore;
- allowing the upper pressure rods guided along two successive downward inclined planes to successively fall by gravity into the respective bores, thereby subjecting the powder contained in each bore to preliminary compression;
- successively compressing the preliminary compressed powder in the bores for a prescribed period of time; and
- further successively compressing the compressed powder in the bores, thereby molding the powder in each bore into a tablet;
- wherein the upper pressure rods are guided along said downward inclined planes to fall into the corresponding bores for effecting said preliminary compression;
- and wherein the weight of upper pressure rod is approximately 800 g.
