Abstract
A conveyor system comprises a plurality of article carriers 5 interconnected for movement in succession along a predetermined path 1, and weight sensing means 7a, 7b positioned at two or more weighing stations in the path such that each article carrier passes through one weighing station, the weight of the article carrier, together with that of any article carried thereby, being applied to the weight sensing means. The use of two weighing stations, to which articles can be diverted alternatively, means that ample time can be allowed for accurate weighing, even if the speed of the article carriers is greater than that with prior art devices.
