Autopack has extended its fast Staircase collator principle to stacking reams of paper. Generally, reams of paper are packed in a stack of 5 inside carton box or shrink wrapped.
Since paper ream production lines are fairly fast, stacking the reams one by one in a single column would be to slow.
To meet the line speed 100 reams per minute, Autopack has designed a heavy duty collator which in a single cycle converts horizontal layer of 5 reams into a vertical stack of 5.
The stack is subsequently ejected for shrink wrapping resulting in a tight pack, ready for stacking on pallet.
