Abstract: A high speed container placement machine in which stationary units consisting of one feeder guide, one load cell and one discharge guide are placed in a spaced-apart relationship along the side of a supply conveyer traveling at a constant speed and carrying at least one row of spaced apart containers. The feeder guides of a particular group of such units simultaneously pick up a plural number of containers from the supply conveyer and place them on their respective load cells. After processing, the discharge guides of the units simultaneously remove the processed containers from the load cells and place them back on the same conveyer again between the arriving containers. The guides are driven by a simple cam and cam-follower variable speed drive mechanism which prevents any unintended interference between the guides and any of the containers.
