Modular folding apparatus

A folding apparatus, comprising a plurality of separate modules,

• one of said modules including a basic frame having connecting means and further connecting means, and to which folding apparatus intake means and at least one transverse cutting and transverse folding unit are mounted, said at least one traverse cutting and transverse folding unit adapted to be fed by a longitudinal folding unit and having a cutting cylinder, a cylinder having a folding blade and pins and a folding jaw cylinder,
• another of said modules including an additional frame having connecting means and to which at least one further longitudinal folding unit is mounted, said at least one further longitudinal folding unit having a belt conveyor adapted to feed a delivery unit, and
• a further one of said modules including a superposed frame having another folding jaw cylinder mounted thereto and another longitudinal folding unit associated therewith, said another longitudinal folding unit being fed by said another folding jaw cylinder, said superposed frame having support surfaces forming connection means, wherein:
• the basic frame and the additional frame having aligned bottom levels,
• the connecting means of said basic frame is located in the vicinity of the folding jaw cylinder of said basic frame, said folding jaw cylinder being at a lower level than the folding blade cylinder and said folding blade cylinder being located in the vicinity of said further connecting means, and
• on their side remote from said basic frame, said additional frame and said superposed frame being provided with superposed connecting means for one respective add-on frame with at least one transverse folder delivery unit which can be actuated as an alternative to said at least one further longitudinal folding unit.
