Abstract
A low cost, on-line saddle stapler accessory for preparing long edge fed booklets, receives side registered copies from a copier, and introduces a crease centrally of the copies. The copies are aided into a roof-shaped compiler tray and registered at their lead edges. When a set has been compiled, a first saddle staple is made and the set is passed on to a second position, registered and stapled a second time. Afterwards, the now saddle stapled booklet is forwarded to a stacking tray.
