Abstract
A weighing arrangement comprises a conveyor system defining a path for articles and including a first feed conveyor, a second upwardly inclined conveyor arranged to receive articles from the first conveyor and a third, downwardly inclined conveyor. The first and second conveyors have respective first and second motors for independent drive. The weighing apparatus has a weight measuring component in the form of a rotatable cylinder which cooperates with load sensing means. In use, an article is fed from the conveyor to the cylinder of the weighing apparatus. Operation of the weighing apparatus is based on the principle that as the article changes direction to be discharged via the downward conveyor there is an instant at which the total mass of the article passes through its center of gravity so as to act directly downwardly via the cylinder on the load sensing means.
