Abstract

A method and system for folding a sheet having a certain length into a folded piece of a fold type having a first edge and a second edge, wherein the sheet length and the fold type are simultaneously selectable. The sheet can be folded once or twice into the folded piece. After the sheet is folded into the folded piece, the folded piece moves in a direction with a first edge leading the second edge. The method and system further include a step and a mechanism to control the moving direction of the folded piece such that the folded piece can be caused to move with the first edge trailing the second edge or allowed to continue to move with the first edge leading the second edge when the folded piece exits the system.
