<p>The device for supplying and metering freshly ground coffee powder in an apparatus for packaging bags of coffee powder according to European Patent No. 0,225,494 comprises a metering device (200), a distribution disc (214) and a closing disc (226) provided with through-holes which can be aligned in predetermined angular positions of the discs themselves, so as to allow the supplying of one or more measures of coffee powder at a time into cavities (250) formed in a link conveyor (10) supporting a bottom strip of filter paper (48) shaped so to have successive receiving cavities. The holes in the metering device and in the closing disc are two in number so as to make use of the fact that in general the circles intersect each other always at two separate points. <IMAGE></p> |
