You need a crash folder. As far as I know, the only one available is from Shoei

I am not sure how that folder is unique. We have an MBO folder and we have tried folding the finished pieces, but when they are stapled it tears the spine.
Just as Bill said, we use our horizon knife folder. Set up the hand feed unit and it folds nearly as fast as you can feed them, and looks great. We have a job of 1200 we do once a month.
Yeah but I think the questions is how do you do 50,000 of them?
