ABSTRACT:
The apparatus for dosing metered amounts of dense pasty pharmaceutical substances and for inserting same into gelatine capsules, comprises an extrusion press which extrudes a layer of substance having a uniform density and a predetermined thickness or height. A hollow punch presenting a cavity is dipped inside said layer for its whole thickness or height, so as to take out of said layer, due to the inherent viscosity of the substance, a predetermined dose of the substance itself. The hollow punch is then positioned above an empty capsule half, and the dose is discharged into the said capsule half by means of an ejecting piston slidably movable at the interior of the hollow punch. The extrusion press comprises two parallel walls, one of which is adjustable so as to vary its distance from the other wall, thus varying the thickness of the layer of substance being extruded.
