Abstract
A carousel carries a holder with product to be dosed and includes a lower disc fitted with peripheral sets of dosing holes into which plungers insert and press in successive stages doses of product. The carousel also includes fixed bodies and radially moveable bodies with seatings for supporting tops and bottoms of capsules. Lower bodies support extensions that close the lower ends of dosing holes in the successive stages, and opposing members are provided to support the moveable assemblies. With only one dosing disc, it is possible to form doses of product of different densities and masses and of different heights by varying the heights of the sets of plungers. A chamber defined by a sweeper wall and containing no product is provided with a plunger station that completes the pressing of this final quantity of product, before a subsequent plunger station discharges the product into the capsule bottoms.
