Abstract
A partition assembly comprising a partition matrix made up of intersecting first and second slotted partitions, each of the partitions having at least one slot. The slots of the partitions are engaged with each other at a plurality of intersections. The partitions are made by folding over a partition blank and securing a foam portion of the folded partition blank to itself. The foam may be heated with hot air before being cooled under pressure to secure opposed plies of the partition together.
