Zusammenfassung:	A folder (110) for a printing press (100) includes a cutting cylinder assembly (128) having at least two knife and anvil cylinder (136, 146) sets positioned near the cutting region of a folder (110). The cutting cylinder assembly (128)slides or actuates one of the knife and anvil cylinder sets (136, 146) into a cutting position for a desired cut length. The web (101) passes between the knife and anvil cylinder set (136, 146) and is cut. When the cut length needs to be changed, the cutting cylinder assembly (128) is relocated to such a position that a second or further set of knife and anvil cylinders (136, 146) is aligned with the web (101).
