ABSTRACT:
The present invention is directed to a method and apparatus for packing tubular bags into boxes by machinery. The tubular bags to be packed are conveyed over various conveyor belts to a positioning belt and from the positioning belt to a positioning table. Layers of tubular bags are then moved onto a rake-like main base that is lowered in a stepwise fashion to receive consecutive layers of tubular bags. When the desired number of tubular bag layers is positioned on the main base, the main base is lowered to deposit the tubular bags onto an intermediate base which together with side walls makes up an intermediate container. Once the intermediate container is in a lower position, a box is pushed over the intermediate container and the intermediate container is swung through a 90.degree. arc onto a conveyor belt. The intermediate container is then removed from the box and by this process the tubular bags which were previously in the intermediate container are transferred into the box. The intermediate container then swings back to its lower position.
