According to a method for statistical weighing of a product supplied by a plurality of nozzles into containers, an empty container, belonging to a withdrawing group, is withdrawn to define an empty seat in the withdrawing group. The withdrawn empty container is weighed by a scale, to determine a tare weight, and then introduced in an empty seat made in a test group of containers, is a position designed to match with a selected nozzle to be tested. After introducing product into the weighed, empty container, by the selected nozzle, the filled container is withdrawn and weighed by the same scale to determine a gross weight. The exact quantity of product introduced into the filled container is thus determined by difference between the tare and gross weights.

Method for statistic weighing of a product introduced into containers in a filling machine

A device for transporting and arranging cylindrical elements in a row has a first conveying belt, operated by first motor means to pull a plurality of cylindrical elements in a feeding direction. A second conveying belt is situated in cascade with respect to the first conveying belt and is operated continuously for receiving and transporting the plurality of cylindrical elements in a direction concordant with the feeding direction. Canalization means are fastened to an upper run of the second conveying belt for intercepting and for guiding the cylindrical elements, being transported on the second conveying belt, in a discharge direction up to an outlet channel, situated on one side thereof. Sensor means are connected with the first motor means and detect the presence of at least one cylindrical element in a selected section of the second conveying belt. The sensor means deactivate the first motor means, after a first time interval, subsequent to detection, and activate them, after a second time interval, when no cylindrical elements are detected in the selected section.
