EUh not at all!
I work during holidays and in weekend in an industrial laundry facility. When I'm ironing, we stand with 2 persons at each side of the machine. We just have to put 2 corners lengthwis in clamps. The machine spreads, feeds, irons and folds the sheets. We each do a batch in 10 min (dunno how much kg, the tunnelwasher is a Lavatectunnelwasher, but have no idea how big the batches are, 20kg?)
It's a kannegieser feeder and folder and a Lapauw ironer.
The folder folds everything except aprons, delicate stuff and some napkins. All sheets and pilowcases are folded automaticly.
