A document stacking bin receives and stacks documents injected therein along a free flight path. The bin includes an energy absorbing device for intercepting the documents in free flight, absorbing their kinetic energy and allowing them to free fall onto a stack. The energy absorbing device includes at least one bead chain having one end fixed and the other end looped over a portion of the bin and attached to a weight.
