Claim:
A machine for filling capsules with at least one product; each capsule comprising a bottom shell ( 2 ), and a top shell closing the bottom shell ( 2 ); the machine comprising a conveyor device ( 16 ) for feeding each bottom shell ( 2 ) continuously along a given path (P); at least one container ( 21 ) for the product; at least one metering wheel ( 5 ) mounted to rotate continuously about a substantially vertical longitudinal axis ( 7 ); and a number of metering devices ( 31 , 42 ) movable with the metering wheel ( 5 ) along a portion of the path (P), in time with relative bottom shells ( 2 ); each metering device ( 31 , 42 ) comprising a respective metering chamber ( 42 ) for transferring the product from the container ( 21 ) into the relative bottom shell ( 2 ), and, for each metering chamber ( 42 ), feed means ( 30 , 45 ) for selectively transferring the product from the container ( 21 ) into the metering chamber ( 42 ); and the machine being characterized by also comprising a weighing device ( 37 , 38 ) for weighing the product contained in each metering chamber ( 42 ); the weighing device ( 37 , 38 ) being connected to the feed means ( 30 , 45 ) to cut off supply of the product from the container ( 21 ) to the metering chamber ( 42 ) when the weight of the product determined by the weighing device ( 37 , 38 ) substantially equals a reference value memorized in the weighing device ( 37 , 38 ).
