Abstract
A printing press having a jaw mode assembly and a rotary mode assembly with a single folding cylinder adapted to feed either the jaw mode assembly or the rotary mode assembly is disclosed. A moving web of material is initially trained about the folding cylinder and cut into a signatures which are then temporarily held on the folding cylinder. A folding blade extends from the folding cylinder to initiate a fold in each signature and direct each signature to either the jaw mode assembly or the rotary mode assembly. The timing of the folding blade is coordinated and adjusted using an indexable spider assembly to feed either the jaw mode assembly or the rotary mode assembly.
