Abstract: The weighing machine comprises a number of aligned weighing receptacles which receive the irregular elongate articles in spaced-apart relationship from a supply apron supplied by a vibrating device from a receiving hopper, and a return device to the receiving hopper for recycling the irregular elongate articles not supplied to the weighing receptacles. The weighings of the weighing receptacles are computerized and the optimal weighing combination is selected within a predetermined margin among the weighings of an arbitrary number of a group of weighing receptacles associated with one weighing machine or with two weighing machines disposed one opposite another, as the case may be.
