    Rotating parts cause hazards such as in-running nip points. Parts can rotate closely to each other in opposite directions while their axes are parallel to each other. When they run closely the stock fed between two rolls produces a nip point. This danger is common on machines with intermeshing gears rolling mills and calendars.
