As a bindery novice, folding machines with pile feeders made me want to pull out my hair, or on a really bad day, someone else’s hair. The bigger the pile of crumpled paper around the folder, the further away my co-workers would stay. Except for one friend who intentionally waited until I reached the breaking point. With a Cheshire grin he’d slap me on the back and say, “Hey, Andre, how’s it going?!” In time, I learned a few things about pile feeders which didn’t keep my friend away, but they kept the folder running smoothly.
