A combinatorial weighing apparatus, having a plurality of juxtaposed weighing machines each of which is provided with a scale, for weighing articles supplied to the weighing machine scales, selecting the combination of articles that gives a total weight equal or closest to a preset target weight, and discharging the articles so selected. The apparatus includes a carry-in conveyor disposed alongside the juxtaposed weighing machines for continuously delivering vessels, filled with a suitable quantity of articles, from a filling station to a selective transfer station, transfer means for selectively transferring the filled vessels on the carry-in conveyor from the conveyor to the scales of individual ones of the weighing machines, a discharge conveyor for retaining and conveying filled vessels received selectively from the weighing machine scales and for discharging the articles from the vessels, and means for pushing the emptied vessels carried on the discharge conveyor from the discharge conveyor onto the filling station of the carry-in conveyor. The transfer means includes transfer cylinders of a number equal to the number of weighing machines, wherein transfer cylinders corresponding to weighing machines belonging to the selected combination are actuated to transfer vessels from the carry-in conveyor to the weighing machine scales and, at the same time, to transfer the vessels already placed on the weighing machine scales from the scales to the discharge conveyor by pushing them with the vessels transferred from the carry-in conveyor.
