  • Patent number: 4308712
    Abstract: Apparatus having a vacuum arrangement for reaching up to grip a flat carton blank and to draw the blank downwardly onto a support. As the blank is moved downwardly, it is drawn into an expanding U formation ready to receive a load of articles which are moved along a path and onto the bottom of the deposited blank, after which the blank is folded into a carton and secured relative the article load. While the loading, folding and securing operations are taking place, the vacuum arrangement moves back to grip the next carton blank that is to be loaded. The apparatus for moving each load inwardly on to the deposited blank allows for the formation of another load while the moving is taking place, said apparatus moving outwardly over the newly formed load.
