Abstract: A partition feeder has a multi-rack assembly for holding more than one reserve stack of partitions. The partition feeder has a main stack of partitions which is forced against a set of tabs and which has its partitions removed by a selecting apparatus. When the main stack has been reduced down past a certain amount, one of the reserve stacks is automatically moved into alignment with the main stack and the partitions in the reserve stack are added to the main stack. The partition feeder has guide rails that are received in notched sides of the partitions, thereby suspending the partitions on the guide rails. An inner frame, upon which the guide rails are mounted, is adjustably mounted to a middle frame to thereby permit the adjustment of the distance between the guide rails. The middle frame is adjustably mounted to an outer frame to permit the vertical adjustment of the mass feeder. The partition feeder can therefore be easily adjusted for partitions of different sizes.

Abstract: Arranging a group of articles to be packaged so as to include a space for the insertion of a different article. All the articles except one are arranged in upright position. The one article is positioned on its side, between other articles. This creates a space above the one article into which a different article is inserted prior to packaging the articles in a multipack carton.
