Description

The invention relates to a method for producing at least one final strip of multi-layered printed documents assembled from a feed reel comprising an initial printed paper web, a feed reel for use in the implementation of such a method and an installation for the implementation of such a method.

The invention also relates to a method for producing at least one finished reel of multi-layered printed documents assembled from an initial strip of printed paper, a finished reel obtained by the implementation of such a method and that an installation for the implementation of such a method.

Furthermore, the invention relates to a method for producing multi-layered printed documents assembled from a feed reel comprising an initial strip of printed paper and an installation for carrying out such a method.

It is known from EP-A-0 673 870 to produce, from a strip of printed paper, multi-layer printed documents by superposing subbands assembled on one of their longitudinal edges and then rewinding together. the subbands and transversely cutting the coil constituted by the superimposed subbands assembled.

Such a method offers many advantages since it allows a simple and fast way to obtain printed documents having a large printing area.

However, it is important to limit, during the superposition of the subbands, the transverse offset of the subbands due in particular to differences in the transverse dimension of the subbands or the positioning of the subbands one above the other . This is detrimental to the aesthetic appearance of the documents made.

In addition, this transverse offset can generate on the finished coil formed by the subbands overhangs on the end sections perpendicular to the axis of the coil.

However, during storage or transport in piles of finished coils, these overhangs can be deformed. During unwinding of the finished spool to produce the printed documents with several superimposed layers assembled, the longitudinal edges of the superimposed assembled subbands are then deformed and are not located in the plane of the subbands.

These deformations alter the aesthetic appearance of documents. In addition, the alteration can be accentuated during the transversal cutting of the subbands. The deformation of the longitudinal edges may, moreover, pose problems of guiding and scrolling superimposed subbands assembled.

Furthermore, it is desirable that with such a type of process, optimum productivity is obtained in each production cycle in which multi-layered printed documents are made from a printed paper web.

The aim of the invention is to improve the production of multi-sheet printed documents by proposing a method for producing a final strip of multi-layered printed documents in which a split of the assembled superimposed subbands makes it possible to adjust the longitudinal edges of the sub-strips. -bands and improve productivity with each cycle.

In connection with the figures, there is described an installation for producing printed documents from a generally cylindrical feed reel 2 of axis M formed by the winding of an initial strip 3 of printed paper.

In the particular application aimed at, the printed documents are leaflets 4 relating to pharmaceutical products, cosmetic products or similar products. Such products 38 are generally arranged in a container 39, for example of the bottle, tube, plate or similar type, the container 39 then being placed in a package 40. According to embodiments, the packaging is of the type of cardboard box shaped general parallelepiped obtained by folding and gluing a blank.

The generally polygonal records 4, in particular rectangular, have two main directions, the longitudinal direction L according to the largest dimension of the record 4 and the transverse direction T perpendicular to the longitudinal direction L.

More generally, in the remainder of the description, the terms "transverse" and "longitudinal" also refer to the two main directions perpendicular to each other of the initial strip 3 considered flat, the longitudinal direction L along the largest dimension of the initial band 3 and the transverse direction T perpendicular to the longitudinal direction L. In particular, when the initial band 3 is wound to form the supply reel 2, the longitudinal and transverse directions T are respectively perpendicular and parallel to the axis M.

To be able to be introduced into the package 40, the notice 4 is folded transversely, as shown in FIG. 3, to obtain a strip 41 whose largest dimension corresponds to the transverse dimension of the notice 4. The strip 41 shown on FIG. Figure 4 is in turn folded in the general shape of U comprising two branches 42 and a base 46, so as to allow the introduction of the container 39 between the branches 42 of the U.

Such leaflets 4 must allow the inclusion of obligatory general information on the use of the product and specific information on the product, such as its definition, composition and effects, and dosage in the case of a pharmaceutical product. The notice 4 may also include information relating to the company that manufactures the product. In addition, it may be necessary to have all of this information in several languages, the notice 4 then including translations of the information.

The records 4 may have a longitudinal dimension L of up to about 40 centimeters and a transverse dimension T of up to about 20 centimeters. However, the constraints related to folding and introduction in the package 40 limit the possibility of increasing the longitudinal dimensions L and transverse T of the notes 4.

It is therefore expected that the record 4 includes several sheets 43 substantially identical in terms of shape and size, superimposed and can be printed on the front and back to increase the printable useful surface of the record 4. Each sheet 43 is made to from a thin sheet, for example of the type bible paper having a basis weight between 20 g / m ² and 40 g / m ² . Such an increase in the printable usable area makes it possible to record all the information intended for the user of the product 38.

To avoid the involuntary separation of the leaflets 43, it is possible to assemble the leaflets 43 to each other on one of their longitudinal edges. Each sheet 43 then comprises an assembly zone 44 in the vicinity of one of its longitudinal edges. In particular examples, the assembly zone has a transverse dimension of the order of a few millimeters, for example between about 3 millimeters and of the order of 8 millimeters, and the assembly of the sheets 43 is produced by means of an adhesive substance 45 disposed between the joining zones of two consecutive sheets 43. According to embodiments, the adhesive substance 45 may be a permanent glue, the sheets 43 being permanently affixed to one another, or a fugitive glue, the sheets 43 being separable from each other without being damaged, or a combination of both.

In the embodiment shown in FIGS. 1 and 2, provision is made to produce records 4 comprising two assembled superimposed sheets 43. In the figures, A and B denote the faces intended to form respectively the front and the back of the upper sheet 43 of the notice 4 and C and D, the faces intended to form respectively the front and the back of the lower sheet 43 4. The visible faces are shown in full lines and the faces opposite to the visible faces in dashes.

To produce a leaflet 4 with two sheets, the initial strip 3 of printed paper shown in FIG. 6 comprises two sub-strips 5a, 5b of substantially identical transverse dimension arranged side by side. In a particular example, the maximum transverse dimension T of the initial band 3 is of the order of 85 centimeters and the grammage of the initial band 3 is between 20 g / m ² and 40 g / m ² . A reference line 6 is printed on the initial strip 3, the two subbands 5a, 5b being disposed on either side of the reference line 6.

More generally, the number of sub-bands 5 is the same as the number of sheets 43 of the instructions 4 that one wishes to achieve. And, in other embodiments, the installation makes it possible to produce records 4 comprising three or more than three sheets 43. The initial band 3 then comprises three sub-bands 5 or more of three sub-bands 5, one line 6 can be printed between two successive subbands.

On the other hand, the installation allows starting from the initial band 3 to make one or more final bands 1 of records 4, that is to say one or more longitudinal successions of records 4.

In particular, to be used in an installation in a simple manner, that is to say without complicating the installation, the supply coil 2 has a maximum diameter of about 1 meter. Thus, in order to optimize productivity without increasing the diameter of the feed reel 2, provision is made from the feed reel 2 for several final bands 1 of instructions 4.

In the embodiment shown, the initial strip 3 makes it possible to produce three final strips 1 of leaflets 4. To this end, each sub-band 5a, 5b comprises three printed elementary strips 7 arranged side by side and having a substantially identical transverse dimension. . The transverse dimension T of the elementary strips 7 is greater than the transverse dimension T of the final strips 1. In the particular example, the dimension transverse T of each final coil 1 may be between 13 centimeters and 14 centimeters.

The impressions of the elementary bands 7 on the same face of a sub-band 5 are identical. Thus, the elementary strips 7 of the sub-band 5a have on one side the impressions intended to form the side A of the upper sheets 43 and on the other side, the impressions intended to form the B side of the upper sheets 43. And the elementary strips 7 sub-band 5b have on one side the impressions intended to form the C side of the lower sheets 43 and on the other side, the impressions intended to form the face D of the lower sheets 43. The faces of the elementary strips 7 intended to form the faces B and C are formed on the same face of the initial strip 3 and the faces of the elementary strips 7 intended to form the faces A and D are formed on the other side of the strip. initial 3.

In general, the number of elementary strips 7 of each sub-band 5 is the same as the number of final bands 1 that one wishes to achieve. It can therefore be expected that each subband 5 comprises a single, two or more than three elementary strips 7 printed to produce a single, two or more than three final bands 1 from the initial band 3. The impressions of the sub faces strips 5 must then be adapted to the method of producing records 4 as will be described later.

To allow the production of the final strips 1, the installation shown in FIGS. 17 to 19 comprises, successively, a first unwinding station of the supply reel 2, a second stacking station of all the sub-strips 5, a third station assembly of all the sub-bands 5 and a fourth longitudinal slitting station of each sub-band 5.

The first and second stations are arranged in a first direction X while the third and fourth stations are arranged in a second direction Y perpendicular to the first direction X. Here is also defined a direction of elevation Z perpendicular to the directions X and Y.

In the first station, unwinding means are mounted on a frame 8 and comprise, at the entrance of the first station, a feed mandrel 9 and, at the outlet of the first station, an exit roller 10. Generally cylindrical bars 11 mounted on the frame 8 form means for running from the initial strip 3 to the exit roll 10. The feed mandrel 9, the output roll 10 and the scroll bars 11 are generally parallel to each other and perpendicular to the direction X.

The first station may include means for controlling and adjusting the position of the initial web 3. It may also be provided that the positions relative to the frame 8 of the feed mandrel 9, the scroll bars 11 and the roll 10 of output can be adjusted automatically or manually. In particular, a device, not shown, for lifting the feed mandrel 9 comprising jacks may be provided in the first station. In addition, additional means for controlling the printing of the initial web 3 and its tension, for example by means of strain gauges arranged on an output roll, can be added to the first station.

The second station comprises adjustable means for superimposing all the sub-bands 5. The superposition means are mounted on a frame 16 and comprise, at the entrance to the second station, elements for slitting the initial strip 3 along an slitting line 12 located between two successive subbands. The slitting elements may comprise circular slitting knives 13 generally located in a plane comprising the X and Z directions and resting against counter knives. The slitting knives 13 and counter-knives are intended to be arranged on either side of the initial strip 3 to allow longitudinal slitting of the initial strip 3 between the subbands 5. The slitting knives 13 are mounted pivoting on a shaft 14 so as to be adjustable, manually or automatically, perpendicularly to the direction X. The counter-knives can be rotated by a motorization 15 about an axis perpendicular to the direction X. Moreover, for security reasons and to limit the risks of disruption of the slitting of the initial strip 3, a not shown safety device comprising in particular a housing in which the slitting knives 13 and counter-knives are arranged may be provided.

In the embodiment shown, the initial strip 3 comprising two subbands 5a, 5b, the slitting elements comprise a single slitting knife 13 and a counter knife disposed between the subbands 5a, 5b.

At the output of the second station, the superposition means comprise turning elements of the subbands 5. The turning elements comprise turnbars mounted on the frame 16. In particular, two turnbars 17 are arranged substantially symmetrically at 45 °. Relative to the plane of a slitting knife 13, the distance between said turning bars 17 being minimal on the side of the slitting knife 13. The turning bars 17 are offset in the Z direction and comprise blowing holes 18 supplied with compressed air by appropriate means not shown to allow the movement of the subbands 5. In addition, a turning bar 19 is disposed in the direction X adjacent the end opposite the slitting knife 13 of one turning bars 17 to 45 °.

The use of rollover bars 17 at 45 ° with respect to the plane of the slitting knife 13 is particularly adapted to the superposition of two successive subbands 5 without particular adjustment and precisely according to a common reference line.

When the initial strip 3 comprises more than two subbands 5 to be stacked, the second station may comprise more than two rollover bars 17 at 45 ° and several bars 19 parallel to the direction X to allow the superposition of the subbands 5 limiting the settings.

In other embodiments not shown, the turning elements may comprise folding cones of the initial band 3 between two successive subbands.

The second station also comprises scroll bars 20 arranged perpendicular to the direction X and guiding the initial band 3 and the subbands 5a, 5b between the slitting elements and the turning elements. It is also possible to provide the second station with means for controlling and adjusting the position of the subbands 5.

In the Y direction, opposite the turning bar 19, is the third station of the installation. This third station is provided with means for assembling all the sub-bands 5 in the vicinity of one of the longitudinal edges of each elementary strip 7 printed.

The assembly means comprise guns 21 in fluid communication with a reservoir of adhesive substance 45, for example glutinous or permanent glue. To allow the adjustment of their position, the guns 21 are mounted on carriages 22 which can slide automatically or manually on a guide 23 mounted perpendicularly to the direction Y on a frame 33.

The third station also comprises means for scrolling the subbands 5 in the form of bars 24 arranged perpendicularly to the direction Y. The scroll bars 24 can make it possible to make up the difference in path followed by the subbands 5 during the reversal. . In particular, scroll bars 24 are arranged in the Z elevation direction. This arrangement makes it possible to place the guns 21 between the superimposed subbands 5 and to deposit the adhesive substance 45 on one of the longitudinal edges of each strip. elemental 7 printed from the lower subband 5.

To ensure a satisfactory assembly of the subbands 5 at the determined locations, that is to say at the locations corresponding substantially to the assembly areas 44 of the sheets 43, a device for checking the presence of adhesive substance 45 can be used in the third post.

Furthermore, at the exit of the third station, the superposition and the assembly of the sub-bands 5 are finalized by means of a call cylinder 25 mounted on the frame 33 and rotated by a motorization of call around an axis perpendicular to the direction Y. The inverting cylinder 25 drives the superimposed subbands 5 via a rubber pressure roller which exerts an adjustable pressure on the subbands 5 in the direction of the inverting cylinder 25 to hold them against this one. For safety reasons, an underrun bar 26 is provided between the call rollers 25 and presser.

Thus, at the exit of the third station, all the sub-bands 5 of the initial band 3 are superimposed and assembled one above the other so that their longitudinal edges are substantially in correspondence. By superposing two successive sub-bands 5 with the longitudinal edges in correspondence, we mean the arrangement of the subbands 5 one above the other, generally overlapping, with the longitudinal edges close to each other . Due to the size of the subbands 5 and the elementary bands 7, stackings of assembled superimposed elementary strips 7 are obtained.

However, it can appear, as shown in Figure 12, a transverse shift d of the longitudinal edges of the elementary strips 7 due in particular to differences in transverse dimension or the positioning of the elementary strips 7 one above the other. This shift d when it is of a dimension that makes it visible, especially greater than of the order of a few tenths of a millimeter, can pose problems of guiding and scrolling stacks of elementary strips 7 superimposed assemblies and aesthetic problems on the records 4 obtained.

Thus, to form the final strips 1 by reducing the transverse offsets d between the longitudinal edges of the elementary strips 7, the installation comprises a fourth station provided with adjustable means for longitudinal slitting of each subband 5 in the vicinity of at least one longitudinal edges of each stack. The longitudinal slitting means are mounted on a frame 34 and comprise second circular slitting knives 27 resting against counter knives 28. The second slitting knives 27 are generally situated in a plane comprising the directions Y and Z and the counter-knives 27. knives 28 are intended to be arranged, on either side, between two stacks of successive elementary strips 7 to allow the longitudinal slitting of all the superimposed subbands 5 assembled.

The second slitting knives 27 are pivotally mounted on a shaft 29 perpendicular to the Y direction and the counter knives 28 are rotated by the drive motor about an axis perpendicular to the Y direction. second ripping knives 27 are adjustable, manually or automatically, perpendicular to the Y direction on the shaft 29. The second circular slitting knives 27 are positioned to perform a longitudinal slitting of the subbands 5 near and outside the areas on which the adhesive substance 45 has been deposited. Moreover, the second slitting knives 27 and the counter knives 28 may be arranged in the housing of a safety device.

As for the previous positions, means for scrolling, checking and adjusting the position of stacked elementary strips 7 superimposed assemblies and final bands 1.

The installation as just described makes it possible to obtain final strips 1 of leaflets 4 with a plurality of assembled superposed leaflets 43 whose edges are substantially in the same plane perpendicular to the plane of the final strip 1.

According to a first variant, it is then possible to provide that the installation allows the direct production of records 4 from the final strips 1. To do this, following the fourth longitudinal sloping station, in the Y direction, the installation comprises a fifth transverse cutting station of the final strips 1. The fifth station comprises adjustable means for transverse cutting of the final strips 1.

According to a second variant, the installation makes it possible to produce a finished reel 30 of records 4, each finished reel 30 being formed by the winding up of a final strip 1. To do this, after the fourth slitting station longitudinal, in the Y direction, the installation comprises a fifth station provided with means for rewinding each final strip 1 and uncoiling the finished coils 30.

In particular, in FIG. 4, the fifth station comprises six pins 31 that can be used in two groups of three so as to allow the rewinding of the final strips 1 and the uncoiling of the finished coils 30. A frame 32 supports three drives that drive the two pins. in two, the permutation between rewinding and unwinding being performed by clutch and braking devices placed on the frame 32.

To produce the instructions 4, the installation of the second variant comprises a sixth station provided with means for transverse cutting of the final strips 1.

Finally, it is possible for the installation to include means for folding the instructions 4 and means for placing the instructions 4 in the package 40 with the container 39 in which the product 38 is disposed.

Such means may, for example, comprise a machine called unrepresented cartoner and receiving the note 4, the blank intended to form the package 40, the container 39 and the product 38. The cartoner ensures the shaping of the blank for obtain the package 40, the introduction of the product 38 into the container 39, the introduction of the container 39 into the package, the transverse folding of the package 4 and its introduction into the package and the closure of the package 40 .

All the means that include the various stations, their settings, their power can be controlled and controlled from a control station.

The installation as just described makes it possible to implement the following method of producing one or more final strips 1 of instructions 4 from a supply reel 2 as described above. FIGS. 6 to 16 diagrammatically represent the steps of the method for producing final bands 1 from an initial band 3.

In FIG. 7, the supply reel 2 is placed on the feed mandrel 9 at the entrance of the first uncoiling station and then rewound in the first direction X. At this stage, the initial web 3 is as shown in FIG. Figure 6 and passes between the scroll bars 11 to the output roller 10. According to the representation, the sub-band 5b is the sub-band furthest from the third station of the installation.

A step of controlling and adjusting the position of the initial band 3 with respect to at least one reference line 6 can be provided between the subbands 5. This step makes it possible, for example, to collect data for setting the the position of the feed mandrel 9, the scroll bars 11 and the output roller 10.

The control and adjustment step is carried out prior to the superposition step of all the subbands 5 assembled in the vicinity of one of the longitudinal edges of each elementary strip 7 printed. This superposition step of all the sub-bands 5, carried out in the second station of the installation and represented in FIGS. 8 to 10, aims at forming one or more stacks of superimposed elementary strips 7 assembled in which the longitudinal edges of the strips elementary elements 7 are substantially in correspondence one above the other.

In particular, in the installation as described above, the superposition step of all the sub-bands 5 comprises a reversal step (FIG. 9) in which the adjacent longitudinal edges of two successive sub-bands 5 are arranged substantially in match one above the other. In this way, because of the transverse dimensions of the subbands 5 and the elementary strips 7, the longitudinal edges of the elementary strips 7 are generally adjusted.

In particular, the reversal step is carried out by placing substantially in correspondence one above the other the longitudinal edges of the subbands 5 adjacent to each reference line 6.

To do this, the reversal step comprises the slitting, represented in FIG. 8, of the initial strip 3 made by the circular knives 13 along the slitting line 12 between two successive subbands 5a, 5b, close to each other. of the reference line 6. Then, the reversal step provides the arrangement of the longitudinal edges of the sub-strips 5a, 5b adjacent to each slitting line 12 substantially in correspondence one above the other.

During a first reversal, the subbands 5 located on either side of each slitting line 12 are returned so as to have scrolls substantially 90 °, in the Y direction, relative to the scrolling of the initial band 3, in the direction X. The scrolls of the subbands 5 are generally symmetrical with respect to a plane perpendicular to the initial band 3 and passing through the slitting line 12. Then, a second reversal is performed in which the one of the sub-bands 5 is returned so as to present a scroll generally identical to that of the other sub-band 5.

The reversing elements described above make it possible to perform such a reversal step. In particular, the turning bars 17 arranged substantially symmetrically at 45 ° and the turning bar 19 arranged in the direction X make it possible to arrange the adjacent edges of the two successive subbands 5a, 5b substantially in correspondence with one above the other. 'other.

In fact, in FIG. 18, the turning bars 17 are disposed substantially at 45 ° with respect to a plane perpendicular to the initial strip 3 and passing through the slitting line 12. The subbands 5a and 5b are turned over and present generally at 90 ° deflections, in the direction Y, with respect to the movement of the initial band 3, in the direction X. The turning bar 17 of the subband 5b is shifted downwards in the direction Z relative to to the turning bar 17 of the subband 5a. The sub-band 5b is then again returned by the turning bar 19 disposed in the direction X so as to have a scroll generally identical in terms of direction and direction, that of the sub-band 5a.

However, the sub-band 5b scrolls below the sub-band 5a with a path offset. The scroll bars 24 of the third station make it possible to make up this difference in path to match the impressions of the elementary strips 7.

After this step of turning the subbands 5 and before a step, carried out at the fourth station, of longitudinal slitting in the vicinity of at least one of the longitudinal edges of each stack, the superposition step comprises an assembly step, shown in Figure 10, in the vicinity of one of the longitudinal edges of each elementary strip 7 printed. Three guns 21 are then positioned above one of the longitudinal edges of the elementary strips 7 to deposit the adhesive substance 45. it is desired to use leaflets 4 whose leaflets 43 are removably or non-removably assembled, the adhesive substance 45 is, for example, a fugitive or permanent glue.

In FIG. 11, the sub-bands 5 at the output of the third station are shown after the passage between the rolls 25 and the presser. A dashed line 35 materializes a cut-out of the sub-band 5a to allow viewing of the sub-band 5b. During the superposition step, the faces of the elementary strips 7 of the subband 5a comprising the impressions B were folded over the faces of the elementary strips 7 of the subband 5b comprising the impressions C so as to form three stacks of elementary strips 7 arranged side by side in which the order of impressions A, B, C and D corresponds to the sequence of the faces of the elementary strips 7. In addition, the adhesive substance 45 has been deposited in the vicinity of a longitudinal edges of each elementary strip 7 of the subband 5b so as to form the assembly zones 44 of the sheets 43.

In other embodiments, it can be provided that the reversal step comprises folding the initial band 3 between two successive subbands 5.

To reduce the transverse offsets d between the longitudinal edges of the elementary strips 7 to a non-visible dimension and not subject to deformations, it is expected to slit longitudinally all the subbands 5 along second slitting lines 36 located in the vicinity of at least one of the longitudinal edges of each stack.

In FIGS. 11 and 12, second slitting lines 36 are provided in the vicinity of each of the edges of the stacks of elementary strips 7. As can be seen in FIG. 12, the slitting lines 36 are made close to and outside areas on which the adhesive substance 45 has been deposited so as not to risk deteriorating the quality of the longitudinal slit.

FIG. 13 shows the slitting of all the sub-strips 5 along the lines 36 made by four second slitting knives 27. Such an embodiment makes it possible to eliminate the banks 37 and to obtain final strips 1, represented on FIGS. 14 to 16, in which the longitudinal edges of the assembled superimposed elementary strips 7 are situated substantially in the same plane perpendicular to the plane of the final strip 1.

The installation according to the first variant allows the implementation of a method of producing records 4 by adding the step of transversely cutting the final strips 1 to the previously described steps.

As for the installation according to the second variant described above, it allows the implementation of a method of producing at least one finished coil 30 of records 4. In such a method, each final strip 1 is rewound to obtain a finished coil 30.

The finished coils 30 thus produced, thanks in particular to the fourth longitudinal slitting station, are generally cylindrical and comprise at least one end section perpendicular to the axis of the coil which is generally flat.

Such finished coils can then be transported or stored in piles without risk of deformation of the longitudinal edges of the final strips 1 and deterioration of the instructions 4 during uncoiling of the finished coils 30.

In the installation according to the second variant, for the production of records 4, it is provided before the transverse cutting step of the final strips 1, the successive steps of rewinding each final strip 1 to obtain a finished coil 30 and unwind the finished coil 30.

In addition, the method of producing the instructions 4 may comprise, following the step of transverse cutting of the final bands 1, the successive steps of folding, for example transversely in the embodiment shown, the records 4 and set up the records 4 in the package 40 with the container 39 in which the product 38 is disposed.
