ABSTRACT:
An improved folder includes a "soft stop" reversible roll nip. Folding is accomplished by feeding a copy sheet into a stepper/servo controlled pinch roll that is under software control. The copy sheet is measured and the reversible roll nip is cycled from full forward to full reverse velocity with controlled acceleration. The reversing of the sheet causes a buckle to be created and the sheet creased by a secondary set of rolls.
