Abstract
A cutting unit is described that contains a pair of cylinders disposed opposite one another with a gap formed there-between for receiving a ribbon. The pair of cylinders include a first cutting cylinder having a periphery with a cutting knife disposed helically about the periphery and a second cylinder. A drive rotates the first cutting cylinder for cutting the ribbon such that a signature cut from the ribbon has a smooth, straight edge.
