Abstract
The present invention provides an apparatus for producing at least two 4-page signatures (340) and an apparatus for producing at least one 16-page signature (460). The signatures are produced by folding and cutting sheets cut from a continuous web in a folding machine (500 or 600). The apparatus of the present invention provides a selectable blade device which folds or folds and cuts sheets being processed in the device. When placed in the fold and cut position, the apparatus is capable of producing at least two 4-page signatures (340) or at least one 16-page signature (460) without the need for a final off-line trimming step.
