ABSTRACT:
A general-purpose document folding machine comprises a folding module including at least one folding blade on a main document path. A pair of feed rollers and a pair of ejector rollers for advancing and ejecting documents are associated with each folding blade, disposed one on each side thereof and adapted to have the rollers driven to advance documents along the main path. At least one deflector flap on the main path diverts selectively from the main path documents that are to be folded. Drive means displace each folding blade transversely to a diverted document facing it in order to fold the document and also displace each folding blade along the main path at a longitudinal speed substantially equal to the rate of advance of the documents along the main path. This is in order to fold a diverted document while in motion and insert it between the rollers of the respective pair of ejector rollers. A guide flap associated with each folding blade is disposed transversely to the main path between the folding blade and the associated pair of ejector rollers and is linked to the main path by the deflector flap when the latter is in its diversion position to define a secondary document path between the folding blade and the associated pair of ejector rollers.
