A high speed mechanical weighing system includes a series of article holders carried by chains and forming a flexible conveyor in which the holders are individually pivoted for movement between carrying and discharging positions. The mechanical weighing devices are spaced along the path followed by the holders with stationary guides alongside the holders which are periodically interrupted to accommodate vertically movable weighing guides. The holders have support members which bear either upon the stationary guides or upon the weighing guides. The holders are closely spaced so that a rearmost support member of a leading holder is positioned to laterally overlap but not bear upon the foremost weighing guide member of a weighing station at which the trailing holder is being weighed. The weighing guide members are sufficiently long as to effect accurate mechanical weighing even if the holders are traveling at high speed.
