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