ABSTRACT:
A partition folding and inserting machine is described which automatically folds a flat partition blank into a partition and then inserts the partition into a box which is moving on a conveyor. A hydraulic lift table is provided at the feed end of the machine for supplying a stack of flat partition blanks to the intake or feed end of a first conveyor. An individual partition blank is lifted from the stack of partition blanks and is moved into the machine by the first conveyor. A tab breaker apparatus initially breaks or severs a portion of the partition blank to facilitate the subsequent folding of the partition blank. A cell opening apparatus engages the upper and lower sides of the partition blank to move the same downwardly to partially form cells at the outer sides of the partition blank. The partially folded partition blank is then moved by means of a second conveyor through a side plow or guide which further deforms the partition blank. An inserter apparatus further folds the partition blank and inserts the same downwardly into a box moving on a conveyor. The partition, when inserted into the box, permits the box to accommodate six containers.
