Abstract: A pair of napper stripper drive shafts interconnected by gearing are each provided with independent overload release clutches that permit overload release of each stripper drive shaft from a single input drive gear without disturbing the timed relationship of the other to the input drive gear. The pair of clutches divide the driving load to the stripper drive shafts so that a more sensitive release spring can be utilized in each clutch. When a stripper is jammed or resists rotation, its respective clutch opens and is locked in the released position until it is manually reset by a pushbutton. Reengagement of the released clutch can only be made when the stripper drive shaft is rotated to its proper timed position, and the clutch is arranged so that the stripper drive shaft can be turned independently of the drive gearing when the clutch is in its released position.
