ABSTRACT:
There is disclosed a machine for producing an item of mail essentially consisting of an enclosure and an envelope therefor. The enclosures are successively fed to a folding station of the machine by a conveyor. The folded enclosures are conveyed to an insertion station of the machine to be readied for insertion into an envelope and are then conveyed to an enveloping station of the machine. Envelope blanks are successively fed by a second conveyor to the enveloping station and wrapped in that station about enclosures, thereby forming an envelope for the enclosures. The first conveyor then feeds the envelopes with the enclosures therein successively to a sealing station; a franking station and a collecting station.
