Abstract

In the context of a folding device comprising at least one transverse folding part which is supplied and discharged by feed tapes and is in the form of a buckle folder with a buckle passage flanked by two outer rolls cooperating with a center roll with the formation of feed nips, such folder having a set of tapes running through it over the center roll, a greater degree of adaptability to the processing of different products and of possibilities of modification of the feed paths may be ensured if the outer roll on the delivery side may be pivoted away from the center roll so as to open up and render ineffective the delivery feed roll nip and the buckle passage may be shifted so that its inlet is over the inlet-side feed plane of the tape set running over the center roll.
