ABSTRACT:
A system for forming and collating printed signatures is disclosed in which a plurality of web supply rolls feed a plurality of continuously operating presses. A rewinding mechanism is provided to form printed web rolls which may be stored until printing has been completed for the entire publication. Slitting apparatus is provided longitudinally to cut each printed web into a plurality of printed ribbons which are thereafter collated to form one or more composite signature ribbons. Folding apparatus continuously folds each signature ribbon longitudinally and the folded ribbons are cross associated to form a compound ribbon moving substantially parallel to the gathering conveyor. The compound ribbon is cut into individual signature sets which are conveyed to the gathering conveyor.
