Empty boxes are moved along said box feed conveyor so that an empty box is in ready position opposite a filling and weighing station for immediate replacement of a filled box, the empty box being utilized to displace the filled box from the filling and weighing station and to move the filled box onto a discharge conveyor arranged along a line parallel to said filling and weighing station line and on the side opposite from the box feed conveyor. Each filling and weighing station independently fills and weighs a box with flowable material including discrete articles, and each station determines when the filled box is ready for displacement onto the discharge box conveyor. Control means is provided along the discharge box conveyor to permit filled boxes on the discharge conveyor to be moved therealong to a discharge point without interference from boxes being displaced from filling and weighing stations. A method of supplying an empty box to each filling and weighing station in accordance with the demand for an empty box at said station.
