<p>An apparatus for metering a plurality of different liquid or pasty masses to a receiving container, which apparatus comprises: first supporting means for supporting containers for the masses in fixed positions; a fixedly disposed annular frame bearing a number of dispensing nozzles controllable by fixedly disposed control means and each individually connectable to said containers via respective conduits; second supporting means controllable by the control means for supporting a receiving container such that this receiving container is displaceable in an annular path corresponding with the annular form of the frame and can be placed temporarily beneath a chosen dispensing nozzle for receiving mass dispensed by this dispensing nozzle; a weighing device on which a receiving container can be placed, which weighing device can supply weight signals to the control means; wherein the weighing deviced is disposed fixedly, is connected to the control means via cable means and supports the second supporting means, and wherein the second supporting means are rotatably drivable round a vertical axis by means of a drive device co-acting with the second supporting means such that when a weighing is performed the drive is inactive such that no forces which can influence the weighing are exerted on these second supporting means, for instance the drive is substantially disengaged from the second supporting means.</p> |
