Definitions

  • the invention relates to folds which are presented in a continuous strip for correspondence or the dissemination of confidential information (pay slips for example).
  • Such bands are formed by bundles of continuous sheets, folded in a screen, each of which constitutes a unitary fold.
  • These products which are generally given the English name of "mailers”, allow editing on a printing machine such as a computer printer, electro-accounting equipment or the like.
  • the lower sheet of the bundle is intended to form for each of the shutters of the folding screen, that is to say for each of the unit folds, the back of the envelope of the fold considered, while the upper sheet forms the faces envelopes.
  • All the intermediate sheets are intended to constitute the interior documents or inserts of each of the folds.
  • the typing of the printer is selectively transferred to some of the sheets, therefore to some of the interior documents, while non-personalized mentions are ie identical for all the folds, are printed on one or more sheets before their assembly.
  • the bundle also has a cover strip, called an archive or control strip, which covers the upper sheet.
  • this tape was mainly intended to collect all of the information entered by the printer in order to allow a possible later control, hence the name of the tape, but at present the capacity of the memories of the .computers render this function useless and the control strip still exists only to "retain" information which must not appear on the upper sheet, that is to say most often all information other than the addresses of recipients which are reported on said upper sheet thanks to carbonaceous pads judiciously placed on the back of the control strip.
  • the lower and upper sheets at least are joined by bonding along their side edges.
  • each of the flaps or folds is sealed at the head and at the bottom by transverse adhesive threads joining the upper and lower sheets through transverse cutouts made on all the intermediate sheets.
  • Detachable perforation lines and / or breaking points allow the recipients to open the folds and extract the interior documents.
  • the bundle is provided with drive perforations located in a detachable marginal zone. These perforations are used to drive the bundle in the printing machine and then in the unitizing device.
  • the bundle After the passage in the printer the bundle is brought to a unitizing device where after removal of the possible strip of cover, the folds are separated from each other along the folding lines in screen either by breaking by either by cutting (cutter). Very often, at the entry of the device, longitudinal cutting wheels detach the marginal zones carrying the drive perforations, but this arrangement is not compulsory, the separation of these zones can be carried out on each fold by its recipient if longitudinal lines of detachable perforations have been provided.
  • unit fold assemblies There are many types of such unit fold assemblies; they sometimes differ from each other by the arrangement of the interior documents, but most often by the arrangement of the lines of detachable perforations and of initiation of rupture, so as to allow a simplification of the mode of opening of the fold and extraction. inserts.
  • the method according to the invention makes it possible to obtain a continuous assembly of folds with free interior documents, from continuous sheets not comprising transverse cuts, which completely eliminates the drawbacks d and e.
  • This process can be implemented with simple equipment, at the user's place, therefore possibly after the passage of at least one of the continuous sheets in the printer, which makes it possible to eliminate the drawbacks a, b and c .
  • the invention provides a manufacturing process conventionally comprising the joining of a lower continuous sheet and an upper continuous sheet, by sealing along their longitudinal edges and along transverse bands overlapping concordant lines of weakness, of constant spacing E 1 and intended for the separation of the unit into unitary plies, sealing produced in particular by pressure in a station comprising at the inlet at least one pair of driving rollers between which are engaged the two sheets conveyed towards said inlet at the same running speed V 1 , equal to the tangential speed of the driving rollers, along separate paths.
  • each intermediate sheet can be carried out in different ways, for example by cutting using rotary knives, or by breaking after incision by means of abrupt but very brief acceleration, or even by conventional breaking obtained by a sharp acceleration of scrolling determining the bursting of the weakening lines.
  • the invention relates only to the mode of insertion of the sheet or sheets intended to form the interior documents and before assembly each sheet is capable of receiving the most diverse treatments or shapings.
  • the sealing device varies according to the means provided.
  • the joining of the lower and upper sheets on the periphery of each of their flaps can result from a simple embossing or crimp-locking, or from stapling or sewing. Sealing can also be obtained by welding with or without the addition of material. Most often, however, the joining will be by bonding, either by simple bonding, threads of adhesive being deposited on at least one of the upper and lower sheets, or by self-bonding, threads of self-adhesive substance being deposited on each of the two lower and upper sheets, or else by heat-bonding after coating with threads of heat-activated adhesive on at least one of the sheets.
  • the device will comprise, downstream of the driving rollers, at least one pair of pressure rollers and, in the case of heat-bonding, at least one of the pairs of pressure rollers will be constituted by heating rollers.
  • the pressure rollers possibly heating, can be smooth cylinders, but when the total thickness of the interior documents becomes large, it is advantageous to provide hollow impression rollers, the development of each imprint corresponding to the interior of the sealing frame of a unitary fold.
  • the method according to the invention can be applied to the manufacture of a continuous set of sealed plies, intended to pass through a machine printer, but it is particularly indicated in the case where the interior documents must receive a direct strike, that is to say the cases where the assembly is carried out at the user's place.
  • the invention also relates to a device for implementing the method, comprising for each sheet a separate circuit along which it is guided and driven by spindle coaches cooperating with perforations formed along its longitudinal edges, said circuit leading to a pair of driving rollers, rolling against each other, which constitutes the entrance to a pressure sealing station.
  • This device is remarkable in that the spikes of the circuit of each intermediate sheet rotates more slowly than those of the circuits of the lower and upper sheets, 1 1 spacing of the lines of weakness provided on each of the sheets for uniting folds being directly proportional to the running speed of the sheet in question, that on the path of each intermediate sheet is arranged, upstream of the sealing station, a device for cutting the edge for eliminating the perforated drive margins, then a device for unitizing by sectioning along the lines of weakness and for routing the successive sections of the intermediate sheet thus formed to the entry driving rollers of the sealing station, where they are introduced between said rollers and between the two lower and upper sheets, is provided by transport means such as the average speed between the instant of the rup ture and that of the entry to the sealing station is substantially equal to the running speed V 1 of the lower and upper sheets mentioned above.
  • the device according to the invention will be disposed between the outlet of a conventional shaping machine comprising all or part of printing stations, perforations, cutting, coating sealing means. and the entrance to a folding folding screen.
  • this device can be made available to a user. In this case, it is arranged upstream of a unitizing machine (breaker for example) and each of its circuits is then supplied by an appropriate continuous sheet, folded in a screen, after passage of at least one of the intermediate sheets in a machine printer, the upper sheet preferably comprising a rectangular cut out opposite the location d identification of the recipient in order to avoid any need for tracking.
  • each intermediate sheet can be carried out by any known means: instant accelerator cooperating with a break-in knife, rotary cutting device, or even conventional breaker printing a strong acceleration of the sheet considered, but followed by '' at least one pair of drive and regulation rollers whose variable speed is regulated by a scroll detector.
  • the assembly includes three layers, namely, a lower sheet 11, an upper sheet 12 and an intermediate sheet 10.
  • Each of said sheets has along perforations at least one of its longitudinal edges ( lOb, llb, 12b) and is guided and driven along a respective circuit, symbolized here by a support roller (14, 15, 16), by spike trainers (17, 18, 19).
  • Each sheet carries equidistant transverse lines of weakness (10a, lla, 12a), two successive lines delimiting a flap corresponding to a unitary fold.
  • the spacing E 1 of the weakening lines is greater than that E 2 presented by the weakening lines 10a of the intermediate sheet 10.
  • At least one of the lower 11 and upper sheets 12 carries sealing means along its longitudinal edges (inside with respect to the perforated margins of drag) and sealing means overlapping the transverse lines of weakness 11a, 12a, these sealing means being activated by pressure or by heat and pressure.
  • the assembly is carried out in a sealing station 20, the inlet of which consists of a pair of driving rollers 13 rolling one on top of the other, and between which the various sheets are engaged, possibly after not on rollers. reference 21.
  • the upper and lower sheets are secured, over the entire periphery to each of their flaps by means of pressing cylinders 22 which may be heated (in the case where the sealing means are constituted by threads of thermo glue -adhesive).
  • the pressing cylinders 22 can be hollow impressions when the thickness of the interior documents of each of the plies requires it.
  • the intermediate sheet 10 is a little narrower than the sheets 11 and 12.
  • the height E 2 of the flaps of the sheet 10 is less than the height E 1 of the flaps of the sheets 11 and 12.
  • the difference in width and the height of the flaps of the strip 10 relative to those of the strips 11 and 12 is at least twice the width of a sealing thread so that the interior document can fit entirely inside the sealing frame. It then suffices that the upper edge of a flap of the sheet 10 is engaged between the driving rollers 13 slightly later than the upper edges. of the flaps of the sheets 11 and 12 and that said intermediate flap is detached from the continuous strip 10 to be accommodated properly between the sheets 11 and 12.
  • the rollers 13 have a tangential speed equal to the running speed V 1 of the sheets 11 and 12, while the scrolling speed V 2 of sheet 10 imposed by the trainers; such that 17 is less than V 1 and such that
  • the sheet 10 is subjected to a very sudden acceleration which causes the bursting of said sheet along the nearest line of weakness 10a, released from the pins.
  • the burst occurs at the time of acceleration and a temporary ripple is formed immediately downstream of the accelerator means, without there being any modification of the scrolling both at speed V 2 upstream and at speed V downstream .
  • the instantaneous accelerator can be constituted for example by a pair of rollers 24, 25 of which at least one 24 is both motor and of elliptical section, and whose tangential speed at the end of the major axis is, for example , equal to twice V 2 .
  • an edge cutter 26 can be provided upstream of the knife 23.
  • FIG. 2 there is an assembly 136 of three sheets, namely a lower sheet 111, an upper sheet 112 and an intermediate sheet 110. Each of these sheets follows a separate path leading it, possibly after passing over rollers of reference 121, at the input 144 of a sealing station where it is caught between two driving rollers 113.
  • the flaps of at least one of the lower 111 and upper 112 sheets each include a frame hot melt coating device and the sealing station is a station thermosouda e g with an oven 143 and hollow impression pressure rollers 122 as mentioned above.
  • the sheets 111 and 112 pass at the same speed V imposed by spike coaches (not shown) which cooperate with marginal perforations of said sheets, the driving rollers 113 have a tangential speed equal to V 1 and the set of two sheets 111 and 112 enclosing the intermediate sheets such as 110 is taken up, immediately downstream of the rollers 113, by spiked conveyors 141 rotating at speed V 1 .
  • the pressure rollers 122 rotate at the same speed which is the running speed of the assembly 136 at the outlet of the sealing station.
  • the sheet 110 is narrower than the sheets 111 and 112 which, themselves, are of the same width in order to be able to overlap exactly.
  • Each sheet has equidistant transverse lines of weakening. The spacing of these lines is E 1 on the sheets 111 and 112 and E 2 ⁇ E 1 on the sheet 110.
  • the sheet 110 scrolls at a speed V 2 , imposed by spike trainers -117, such than
  • the invention resides in the mode of insertion of the intermediate sheet 110 or, more precisely, of sections coming from the bursting of the sheet 110 along its transverse lines of weakness.
  • the sheet 110 passes through a single or double edge cutter 126 depending on whether the sheet has marginal drive perforations along a single edge (for example, wide sheet folded longitudinally at the entrance to its respective route) or along its two longitudinal edges.
  • the edge cutter 126 comprises, in a known manner, a knurling device 126a for continuously cutting the corresponding marginal zone and a rotary cutter 126b for reducing into short pieces the continuous strip detached by the knobs 126a.
  • the sheet 110 Downstream of the edge cutter 126, the sheet 110 passes through a "spark gap" or breaker constituted essentially, in a traditional manner, on the one hand, by two pairs of rollers, namely a first pair 130 whose tangential speed is substantially equal at V and a second pair of rollers 131 whose tangential speed is substantially equal to 2 V and, on the other hand, by a wedge 133 of initiation of rupture arranged between the two pairs of above-mentioned rollers and intended to lower to the passage of each weakening line so as to "sink" it over at least part of its length.
  • a spark gap or breaker constituted essentially, in a traditional manner, on the one hand, by two pairs of rollers, namely a first pair 130 whose tangential speed is substantially equal at V and a second pair of rollers 131 whose tangential speed is substantially equal to 2 V and, on the other hand, by a wedge 133 of initiation of rupture arranged between the two pairs of above-mentione
  • each section of the sheet 10 is taken up by retarder rollers 132 whose speed is automatically adjusted by the signals coming from a position indicator 135 so that the spacing between two sections of successive sheets is constant and equal to E1 - E2 , which amounts to saying that the retarder rollers 132 reduce the average speed between the moment of failure and the inlet 144 of the sealing station to a value substantially equal to V 1 .
  • each section must be taken by a downstream drive means at the latest when it escapes from an upstream drive means, this that is to say that it is necessary to be able to adjust the spacing of the different stations (26, 23, 24, 13 and 126, 133, 131, 132, 113) according to the format E of the flaps of the sheet 10 or 110.
  • these various positions can slide along slides provided on the machine and be locked in relative position, the sliding paths of the sheet 10 or 110 then sections of this sheet being constituted by belts which can be unwound from retractable reels elastic as shown by way of example , in FIG. 2, with the sliding belts 137 and 138 and their respective reels 139 and 140.
  • the device of FIG. 1 or of FIG. 2 is incorporated in the chain of fa- brigation and forms part of the shaping machine.
  • Each sheet takes place from a respective reel and passes through the various traditional printing, perforating, cutting, gluing or other coating stations to arrive at the terminal part shown.
  • the scrolling of the intermediate sheets must be slower than that of the upper and lower sheets from one end of the shaping to the other.
  • the shaping is completed in a folding folding station, possibly after addition by lateral embossing of a cover strip.
  • the method of inserting interior documents with the device is particularly suitable for implementation by the user, which makes it possible to solve many problems. Indeed, it suffices for the user to feed the device from "screens" of the various sheets, sheets 11 and 12 (or 111 and 112) being supplied to him, possibly with various prints, ready to use and sheets 10 (or 110) having been previously filled in by its machine printer (by simple typing, or in Y with longitudinal folding). Thus, at least one, but possibly all interior documents can receive a direct strike allowing an exploitation by optical or magnetic reading.
  • the upper sheet 12 (or 112) is provided with windows 27 corresponding to the location of the identification of the recipient on the sheet 10 (or 110); however, to eliminate possible waste, it is useful to provide at various points with circuits of the various sheets of presence indicators (feelers or photocells).
  • the invention is not limited to the embodiment described and shown. First of all, it only concerns the mode of insertion of the interior document (s), whatever the treatments and shapings undergone by the continuous sheets before they are superimposed and whatever the means of assembling the upper and lower sheets ( bonding, welding, heat sealing by heating cylinders or by passage through an oven or by any other heating means, etc.). In addition, modifications can be made to the mechanical means used for implementing the method, without thereby departing from the scope of the invention.
