Abstract: A collating method, particularly for a continuous production line of mailing covers that makes it possible to simultaneously collate the documents to be folded and their envelope and fold them in order to obtain a mailing cover finished in a single pass. The method includes, during the collating step, that the documents (1) to be enclosed are stacked and then advanced at a predetermined pace (P). The envelope (2) is next stacked such that the envelope (2) at least partially covers the documents (1) and the envelope (2), which are offset and carried away at the predetermined pace (P) toward a folding area. The collating method is for use in production lines for mailing covers of the like.

Abstract: A method for producing unique and personalized pieces of mail, including integrating envelope production with the production of the documents for insertion within the envelopes. The machine for producing the pieces of mail includes a device for producing, from the same width of paper, both the documents and the envelopes designed to contain the documents. A longitudinal cutting device cuts the documents to the correct width and forms the flaps of the envelopes. A transverse cutting device separates the documents from the envelopes and cuts them to the correct length. A device assembles the documents with the corresponding envelope. A gluing and folding device closes the envelope while a central processing unit regulates at least the cutting devices, according to the number and format of the documents, and the stuffed envelopes to be produced.

Abstract: The invention concerns a device for cutting, from a width of continuously conveyed material, a variable longitudinal profile in a controlled, irregular sequence, which nevertheless remains a simple, economical, easily implemented and configured device responsive to high speed production requirements. The cutting device has a pair of cutting tools cooperating with an elongate counter-cylinder extending perpendicular to the direction the width of material is conveyed. The cutting tools are movable along two axes from the frame: a rotational axis, perpendicular to the counter-cylinder so as to modify the cutting angle of each cutting tool, and a translational axis parallel to the counter-cylinder so as to modify the distance between the cutting tools. Each cutting tool is connected with a rotational and a translational drive mechanism which are controlled by a central processing unit according to a cutting line with a variable profile and in a given irregular sequence.
