• PRIOR ART Devices of this type are already known for enclosing letters and / or annexes for distribution by mail on a large scale. These devices are usually of complicated construction and include a large number of moving mechanical components for guiding and routing the envelopes on the one hand and the letters with the annexes on the other hand to a junction area of the two elements of the shipment, called the envelopeing area. Since the routes for envelopes and mail and annexes are separate, but the enveloping area is common, in the known devices, the envelopes are routed in a trajectory opposite to that of the documents to be put folded before being evacuated. Envelopes usually arrive in a position such that their windows are facing upwards.
• the documents to be introduced comprising, on the one hand, a letter or other mail bearing a consignee address and, on the other hand, annexes, and must arrive in the envelope box in such a way that the mail is on the top of the envelope. the stack and the annexes below.
• This positioning involves a phase of reversal of the group consisting of at least one letter and its annexes. Indeed, the letter is brought first and the annexes coming from stocks arranged on the trajectory of routing of the letter are deposited successively and selectively on this letter. Therefore, in order for the recipient's address to remain visible and appear in the envelope window, it is necessary that the letter be filed first, with its address at the bottom and that the annexes be placed on the back of the letter. to not hide the address. As the envelope presents its window on the top, the group composed of the letter and the appendices must obligatorily undergo a reversal.
• the turning units have a complicated construction and their operation is relatively slow and leads to a significant reduction in the rate of wrapping. Indeed, in this system, each cycle must be completely completed before the next cycle can be started, that is to say that an envelope must be loaded with the documents that are intended for it and evacuated from the placing area. folds before the next envelope can be moved to the same area to receive the documents. The rate is therefore limited according to the slowest module of line. Or the turning module can be undoubtedly considered a retarder element. We are currently seeking to improve the performance of these lines of envelopes by improving the performance of the modules that compose them and especially by simplifying their construction which is very complicated, expensive and prevents the desired increase in the operating rate.
• US Pat. No. 3,253,384 relates to a document enveloping machine which is essentially capable of folding the documents before putting them into the envelopes.
• This machine has a relatively slow rate of the order of 4'0OO to 6'0OO envelopes per hour.
• the current rates exceed 20'0000 envelopes per hour and the folding of ancillary documents is done on separate units which are arranged in parallel with the packaging module.
• the object of the present invention is to overcome the disadvantages of known devices by providing a simple and effective device of economical construction, which is easy to maintain and which allows to automatically fold at very high speed.
• the stack envelopes are stored in such a manner that the closure flaps are located on the bottom and oriented forwards in a sampling direction, in that said closing flaps are unfolded to open said pockets, in that said envelope closure flaps are brought into contact with a surface of a rotating cam for supporting and reversing the envelopes, in that the envelopes are moved successively by pulling them by their closure flap, said closure flap and said back wall being pressed against said surface of said rotary support and reversing cam, towards an area of introduction of such letters, mail and / or documents and / or said objects, in that the pockets of the envelopes are opened by disengaging the closure flaps of said rotary support and reversing cam and then disengaging said back wall from the pockets of said surface of said rotary cam handling and reversal, in that one introduces directly said letter, said mail and / or said documents and / or said objects in these pockets, before discharging the filled envelopes.
