A high-speed weighing and conveying system, suitable for use in filling soup cans and weighing each as it passes over a weigh platform to a can closer. The open-topped cans slide smoothly and in positive index at all times through a filler and then, in sequence, to an accelerating screw conveyor, to a weigh conveyor which guides them as they slide over the weighing platform, to another screw conveyor, and to a further conveyor which delivers them at the proper times to a closer; an automatic rejector is preferably positioned between the second screw conveyor and the closer to remove from the train of cans, prior to the closer, any can which with its contents has an unacceptable weight. The top portion of the weighing platform is in the form of a longitudinally extending channel member, and the weigh conveyor comprises a pair of rails extending through the channel to support a pair of roller chains having outwardly-extending spaced lugs. The rails are supported independently and free of the platform, and the lugs extend upwardly through the channel to above the top surface of the platform on which the cans slide, in a position behind each can to guide its sliding motion while leaving it essentially free as it traverses the platform. All conveyors, the filler and the closer are synchronized and phased by positive drive from a common drive motor.
