Abstract: In order to eliminate gusset wrinkles in a closed end signature, a unique new and improved method and apparatus are disclosed. The method and apparatus contemplate printing a plurality of webs on presses to provide ribbons to be utilized in forming the signatures, delivering the ribbons after the webs have been printed on the presses to a common point for ribbon merger, and merging the ribbons at the common point to provide a composite to be utilized in forming the signatures. They further include folding the composite in order to form backbone folds defining the closed ends of the signatures, cutting the composite into individual ones of the signatures before or after folding to form the backbone folds, and again folding the individual ones of the signatures cut from the composite in order to form intermediate folds.
