a strapping device for applying a plurality of straps to the body blank.

11. A machine in accordance with claim 10 wherein said strapping device is configured to apply a first strap a first distance from a top edge of the body blank and a second strap a second distance from a top edge of the body blank, wherein the second distance is greater than the first distance.

12. A machine in accordance with claim 10 wherein said strapping device is configured to apply the plurality of straps to the body blank, wherein a first strap is applied a distance from the top edge of the body blank and each subsequent strap is applied a distance further from the top edge of the body blank than the previously applied strap.

13. A machine in accordance with claim 10 wherein said body blank feeding device comprises a scissor lift and a vacuum, said scissor lift lifts the stack of body blanks toward said vacuum, and said vacuum removes one body blank from the stack of body blanks.

14. A machine in accordance with claim 10 further comprising a glue applicator for applying glue to predetermined locations of the bottom blank and a compression device for compressing the predetermined locations of the bottom blank against the body blank.

15. A machine in accordance with claim 10 wherein the erecting device comprises a plurality of vacuums for partially erecting the body blank.

16. A machine in accordance with claim 10 wherein the erecting device further comprises at least two vacuum cups for partially folding the bottom blank.

17. A machine in accordance with claim 10 further comprising a unitizing device for stacking a plurality of reinforced, collapsed bulk bin assemblies in alternating positions to facilitate forming a level stack of reinforced, collapsed bulk bin assemblies, wherein alternating positions includes each reinforced, collapsed bulk bin included within the stack rotated substantially 180 degrees relative to a next adjacent reinforced, collapsed bulk bin assembly within the stack.

18. A machine in accordance with claim 10 further comprising a plurality of conveyors for advancing the body blank through portions of said machine.
