ABSTRACT:
A method and apparatus provides for the formation of compression dosage units from tableting feedstock. A feedstock dossiter is provided including an open ended chamber for insertion into a reservoir containing the tableting feedstock. The dossiter includes a movable die punch which is movable within the chamber between at least two positions. A first position away from the open end of the chamber provides for the collection of a preselected volume of tableting feedstock from the reservoir. The die punch is movable to a second position which effects formation of the tablet within the accumulation chamber. The dossiter shown herein may be used in combination with a fixed die punch to form the tablet.
