A first star wheel (6) transfers shuttles having batches placed therein towards a forming carousel (4) where the batches of plastic material are pressed to form round gaskets (13). A second star wheel (7) is adapted to transfer shuttles with the molded gaskets (13) towards a further carousel (5), where elements are provided to extract the round gaskets (13) from the shuttles and to introduce them into cups (14). At the bottom of the inserting carousel (5) a star wheel (9) for moving away completed closures (15) and a star wheel (8) for transferring the evacuated shuttles towards the batching carousel (3) are provided.
