Description

The invention relates to a poster preparation machine intended to be subsequently assembled to obtain a train of posters for use in rolling billboards. The invention will be more particularly described with regard to posters for rolling billboards, without being limited thereto.

Once the visuals are intended to become posters, and printed at a printer on a continuous sheet one after the other, the sheet is rolled up in a coil form and sent to a specialized poster preparation workshop, which prepares visuals in individual posters that can later be assembled in posters.

The reel of printed visuals is unrolled and the visuals are cut out according to their width to be prepared individually in the form of posters. The standard dimensions of a poster are either 2 square meters (so-called small posters) with a width of 2500 mm, or 8 or 9 square meters (so-called large posters) with a width of 3200 mm or 3600 mm respectively.

In the remainder of the description, the word "width" or "width" of a poster means the horizontal dimension of the poster relating to a vertical notion of positioning the poster when one looks at its graphic impression / its visual. . Its edges

By the term "lateral" is meant the dimension corresponding to the height of the poster in the position of display of the poster, that is to say the direction perpendicular to the width.

The edges parallel to the width and perpendicular to the lateral edges are said transverse edges.

The preparation of a poster consists of cutting (trimming) its side edges, possibly affix on said cut edges a reinforcing adhesive (mainly for large posters), then fix assembly means of the zip type on the two edges crosswise bottom and top of the width, if necessary add an additional adhesive for a reinforced fastening of the zip on the poster, and finally re-roll up the individual posters prepared for their delivery.

Today, poster preparation is done in several manual or semi-automated steps.

Partial preparation machines are available which, after unrolling the reel, produce printed visuals, trimming the lateral edges of the posters and cutting the posters (visuals) parallel to the width of the sheet. However, these machines do not allow to deposit zip. The zip is manually deposited on each separate poster, as well as reinforcing adhesives.

However, the manual preparation work that follows the cuts is tedious for the operator and any productivity gain is impossible.

There are also known machines that perform the apposition of zip continuously (during scrolling) on a coil unrolled, then temporarily stops the machine to cut the posters individually. However, these machines can not handle large posters of 8 or 9 m2. In addition, they do not make it possible to affix if necessary reinforcing adhesives on the lateral edges of the posters, and on the zip once these posed. The object of the invention is therefore to propose an automated preparation machine which obviates the abovementioned drawbacks, in particular by carrying out all the preparation operations, including the optional ones, in an automated, reliable and rapid manner, while allowing, when necessary, a winding posters individually prepared. The invention also aims through such a fully automated machine, to allow its implementation directly to printers who can then deliver posters ready ready directly to the displays, the latter no longer necessarily need to resort to subcontractors for the preparation of the posters. In addition, the same machine aims to treat posters as small (2 m2) as large (8 or 9 m2).

According to the invention, the automated machine for preparing individual posters, in particular the posters being subsequently intended to be assembled to obtain a train of posters for use in pull-down advertising panels, comprises drive means for in a running direction X convey a continuous sheet on which are printed visuals to be prepared as individual posters, cutting means, means for depositing (fastening) fastening systems of the zip type, and is characterized in that the depositing means of the assembly systems of the zip type are implemented transversely to the direction of travel.

The term "assembly systems" means means made solidarity posters and intended to allow later assembly of at least two posters by their width to achieve a train of posters.

Thus, at the end of the preparation of the posters, they can if necessary be rolled up for packaging immediately after assembly of the zip. The winding being parallel to the longitudinal direction of the assembly systems (zip), it is done in the continuity at the output of the machine without having to change angularly the arrival of the posters, since the posters come out with their zip already placed parallel to the winding direction. This winding step in the continuity of the scrolling direction of the posters with the prior operation of fixing the zip perpendicularly to the direction of travel, is impossible in the prior art for which the zip is instead assembled in the direction of scrolling. which does not allow to roll up immediately after the posters which would otherwise need to be turned at 90 °.

In addition, this machine that can handle posters regardless of their width, especially large posters (large width of 5 m for example), allows printers to print large posters, posters of larger size. width than those today handled by existing automated machines that set the zip, gaining in printing time and production. Indeed, as and when printing, the sheet is rolled parallel to its width; when the sheet is then unwound by the machine of the invention, the attachment of the zip will be well according to the width since it will be perpendicular to the unwinding direction. In contrast, the prior art machines that automatically fix the zip perform the operation in the unwinding direction, that is, perpendicularly to the width of the print, imposing print widths on the printers. which are today at the maximum of order especially 3.2 m so that the visual once the poster in place in a rolling panel is in the right direction from top to bottom. Today, zip fastening for large poster widths can only be done manually.

Moreover, the machine of the invention allows processing directly printed posters; it can thus be associated immediately at the output of a printer.

According to one characteristic, the machine comprises additional functional means which, in combination with the drive means, the cutting means, the means for depositing the assembly systems, constitute automated means designed to supply from a continuous sheet printed with consecutive visuals, cut-out individual posters which have, on the one hand, according to the width on their transverse edges up and down, edges perpendicular to the axis of movement of the machine, assembly systems of the zip type, and possibly reinforcement adhesives arranged on the base of the assembly systems, and secondly, on at least one lateral edge perpendicular to the transverse edges, one or more reflective and / or inductive detection type marking elements. , such as aluminum reflective coated labels, and optionally on the two opposite side edges of the adhesive adhesives. enfort.

Therefore, the machine of the invention, which forms a unitary assembly, allows to perform automatically, without manual intervention, all the processing operations that must undergo the printed continuous sheet to provide individual posters fully prepared and ready to theirs. use.

The term "treatment operations" means all the operations undergone by the sheet, the affixing of marking elements, cutting, deposition of assembly systems, application of adhesive.

According to one characteristic, the drive means which are motorized, also constitute unwinding means of the continuous sheet when it is at the entrance of the machine in the form of a coil.

The unwinding and scrolling direction of the unwound sheet, or even the winding of the posters once prepared, corresponds to the dimension which is intended to constitute the height of the posters.

According to the invention, the machine comprises (towards its downstream), transverse cutting means capable of cutting the sheet along the width perpendicular to the direction of movement to separate the visuals in individual posters, means of depositing systems of assembly such as zip, preferably in addition, means for affixing reinforcing adhesive on a part of the assembly systems (the base of the zip), said transverse section means, depositing means, means for apposition being implemented during temporary stops scroll, preferably said means of cross section, deposition means, apposition means being carried consecutively (adjacent linearly) by a common support which is adapted to move perpendicular to the scroll direction.

According to the invention, the poster preparation machine comprising the driving means, the cutting means, the deposition means of zip-type assembly systems, and the additional functional means is designed (has means) for combine the following steps: unwind a reel of a rolled sheet and scroll the unrolled sheet of the reel perfectly parallel to the direction of travel X (that is to say that the lateral edges of the unwound sheet are perfectly parallel at the direction of movement X), continuously affix on the sheet of the marking elements on at least one lateral edge, possibly continuously cutting (trimming) the two opposite lateral edges of the sheet and / or cutting the sheet in several widths ( in order to provide the posters at the desired dimensions with respect to the width), possibly to affix continuously after the cutting of the opposite lateral edges ort on said side edges, temporarily stop the sheet and cut it transversely to the direction of movement X to provide at each stop downstream of the cut at least one individual poster (it is possible to provide two adjacent individual posters if the width of the sheet was upstream split in two), concomitantly affix two assembly systems of the zip type, respectively on the bottom edge of the poster just cut out and on the top edge of the consecutive sheet, and possibly affix a reinforcing adhesive on assembly systems.

Thus, although the machine stops the scrolling of the coil during the transverse cutting and the affixing of the zip, this machine has the advantage of combining all the preparation operations, including those optional, in a minimum time. Therefore, surprisingly, despite a semi-continuous scrolling of a continuous sheet of visuals / posters to be prepared by temporarily stopping the machine to perform the successive operations of transverse cutting and apposition of zip, this machine does not generate a yield loss but rather allows all operations including optional ones to be performed in a completely optimized time. The machine generates in particular a production of at least two posters prepared per minute for large sizes and at least three posters prepared per minute for small sizes, when all operations including optional are carried out, ie at least 60 posters at the same time. time, which is a very good performance compared to the current figure of 30 posters per hour. In addition, this performance is fully compatible with the print speed of posters which is half the speed.

The term "up" and "down" refers to a poster, the opposite transverse edges of a poster with a zip.

In the remainder of the description, the terms "upstream" and "downstream" are understood by qualifying elements with respect to the scrolling direction of the sheet, from upstream to downstream.

According to another characteristic, the machine comprises loading rollers arranged immediately upstream of the drive means and means ensuring the possible operations of adhesive deposition on the lateral edges and lateral cuts (trimming of the lateral edges). The rollers are rollers located under the plane P of sheet processing, which ensure a descent of the sheet from the plane P to the level of their lower peripheral surface by cooperating with said bottom surface, and then following the peripheral contour, a rise from the leaf to the plane P

Preferably, the machine comprises means for regulating unwinding of a reel intended to be placed upstream of the machine and comprising the visual sheet to unwind and to process, preferably said regulation means comprising a motorized regulation puppet.

Advantageously, the machine comprises position detection means cooperating with one of the lateral edges of the sheet, in particular the detection means identifying the position of the edge of the sheet, and the position of lateral marking elements and lines of separation of the visuals on the sheet.

According to yet another characteristic, the machine comprises means for supporting a reel to unwind by the machine, which comprise two remote supports intended to cooperate with the lateral ends of the reel, at least one of the supports being capable of being mobile in translation perpendicular to the scroll to adapt to each coil width and to rectify the drift of the width during scrolling.

The coil 2 is arranged as visible in FIGS. 2 to 3b at the inlet of the machine, to reach the output of the machine to be supplied by following prepared individual posters 2A, 2B, etc., as illustrated schematically in FIG.

The spool 2, as illustrated in FIG. 4, partially unrolled outside the machine for a better understanding, comes from an impression of a multiplicity of visuals VI, V2, etc. which were continuously printed one after the other on a support sheet 2 '(paper-based), the sheet having been wound after printing in the form of a reel for further processing. Each visual is intended to match a poster.

The posters before treatment are as in Figure 4. When the coil 2 is unwound, the sheet 2 'has an X direction of unwinding and scrolling of the machine 1, which corresponds to the height of the posters, and a transverse Y direction which corresponds to the width of the posters and the cutting direction of the spool to separate the posters / visuals individually. Each visual VI, V2 (and therefore posters before treatment) is made distinct from the following by at least one, preferably two lines of registration 20 and 21 parallel and spaced.

The machine 1 is intended to separate the visuals VI, V2, etc. and prepare them as individual posters 2A, 2B, etc. such as that 2A shown in FIG.

According to the invention, the machine 1 automatically groups all the operations to ensure, without any manual task, the preparation of the posters 2A, 2B, etc.

According to the invention, the machine 1 of the invention makes it possible to combine different operations in an automated manner to obtain as a result the poster 2A illustrated in FIG. 4, made of a sheet cut at least parallel to the lines 20 and 21 (FIG. 4) and at the level of said lines to form the edges (parallel to the Y axis) upstream / up 22C and downstream / down 22D (Figure 5), while providing the latter assembly means of the type zip 25A and 25B and optionally reinforcing adhesive 26A, 26B on the base of the zip, and providing at least one lateral edge 22A of one or more marking elements 24, and optionally the cut sheet being provided with reinforcing adhesives 23A, 23B on its edges.

To achieve this result, the machine 1 of the invention performs the following operations automatically, once the coil 2 loaded at the entrance of the machine and partially unwound to drive means: a) unwind the coil, b) regulate unwinding of the spool, c) pulling, driving and pushing the unrolled sheet, d) measuring and correcting if necessary the drift of the width, the width to continuously be perfectly parallel to the Y axis so that the lateral edges of the unwound sheet are perfectly parallel to the axis X of unwinding / running of the machine, e) depositing at least one, preferably marking elements 24, in particular two spaced apart marking elements 24, f) possibly cutting continuously in the direction X the two opposite side edges 22A and 22B of the unwound sheet and capturing the cutting rims, g) optionally continuously applying the reinforcing adhesives 23A and 23B, h) optionally split the web along the X axis continuously to separate it in two, two distinct visuals having been printed on the width of the coil to be separated (for example to obtain two adjacent posters 2 m wide), i) stopping temporarily and periodically the unwinding of the coil while maintaining flat and in position the unwound sheet 2 ', the holding in position being preferably by suction under the lower surface of the sheet, j) during the first stop of the unwinding , apply the first top zip 25A of the first unrolled poster 2A, and optionally thereafter deposit an additional reinforcing adhesive 26A, k) during the second stop unwinding, cut along the Y axis and lines 20 and 21 to separate the first displays 2A as an individual poster, the next 2B is still part of the unwound sheet 2 ', fix immediately after cutting the bottom zip 25B of the at the first upstream poster 2A and concomitantly the top zip 25A of the second consecutive poster 2B downstream, and possibly following the fixing of the zip, deposit an additional adhesive of low reinforcement 26B, and high 26A on the just deposited zip 25B of the 2A upstream poster, and respectively 25A of the poster 2B downstream, l) capture the cutting rakes along the Y axis, m) evacuate the first prepared individual poster 2A, and repeat the operations of step k) ci- top to cut the second poster 2B and finish preparing it, while the next poster associated with the unwrapped sheet is being prepared and so on.

In order to ensure the various operations above, the machine 1 of the invention comprises, with reference to FIGS. 1 to 3b and 7, various functional means carried by the frame of the machine and for some actuated, controlled by an automated system of S control illustrated schematically in Figure 1. The various functional means are as follows: support means 3 of the coil 2 also able to participate in the correction of a parallelism defect of the lateral edges of the unwound sheet with respect to the scroll axis X (still called drift of the width); supply and support means 3 'of the unrolled sheet 2' at the height of the working plane P, that is to say the unwound coil processing plane for the cuts, the applications of the reinforcing adhesives and zip; drive and pulling means 4 and unwinding of the coil; driving and pushing means 4 'of the unrolled sheet cooperating with the traction means 4, the traction drive means 4 and push 4' being able to be stopped to temporarily stop the unwinding, means / bearing surfaces 5 of the unwound sheet at the level of the work plane P; several rollers, preferably three rollers 60, 61 and 62 distributed from upstream to downstream; regulating means 6 for unwinding the coil; position detecting means 7 cooperating with one of the lateral edges of the unrolled sheet 2 ', a deposition device 8 of the marking elements 24; two deposition devices 8A and 8B of reinforcing adhesive on the respective lateral edges of the unwound sheet; cutting means 9 and 9 'of the lateral edges and possibly so-called intermediate cutting means 9 "for dividing the width in two (the cutting means being shown in dashed lines in FIG. 2 for a better understanding but arranged below the second roller 61), advantageously carried by a common support 90A, - transverse section means 9A (FIG. 7) able to cut the sheet unwound parallel to the axis Y to separate the visuals in individual posters; 9B deposition and fixing device (FIG. 7); deposition / application means 9C of reinforcing adhesive (FIG. 7) on the base of the zip fastening strip; a support table 10 equipped with suction means 11 for supporting the unwrapped sheet and holding it in position to ensure thereon the operations of transverse cutting and fixing the zip and deposition of reinforcing adhesive, preferably means for heading the cutting edges of the paper on the entire machine, in particular means not shown for catching the ribbons of the lateral edges, means 12 for catching the rogne / the transverse cut of the lines 20 and 21 separating two visuals / posters ; preferably, discharge means 13 of the individual posters downstream of the machine; optionally, a winding system 14 of the individual posters at the machine outlet; preferably, a connection table 33 located upstream of the machine and a connecting device 34 arranged above the connection table 33 (the table and the connecting device being only illustrated in Figure 2).

The automated control system S manages the operation of the machine; it comprises in particular a programmable controller and / or a variable speed drive and electronic processing means for processing the acquisition of the measurements made by the detection means 7 and generating all the control commands to the different technical elements of the machine to be actuated.

The support means 3 are arranged at the upstream end of the machine to carry the spool 2 parallel to the Y axis and to unroll it in the X direction.

The support means 3 are arranged in the lower part of the machine, below the work plane P.

The support means 3 comprises a first lateral support 3A which is fixed and arranged on one of the lateral edges of the machine, and a second lateral support 3B remote which is opposite to the first in a plane parallel to the axis Y.

Each support 3A, 3B comprises firstly a shaft 31 on which is mounted one end of the coil, the shaft cooperating with the hollow axis of the coil, and secondly a flange 32 of transverse plane to the shaft 31 and against which is intended to abut the end of the coil.

Advantageously, the second support 3B is able to be movable parallel to the Y axis. It is arranged on a mobile carriage which is displaceable in translation along one or two rails 3C and 3D parallel to the Y axis.

The second support 3B being mobile makes it possible to adapt the separation distance of the two supports 3A and 3B in order to fix reels of different width, in particular a coil of 3200 mm or 3600 mm wide for posters respectively of 8 or 9 m2. , or a 2500 mm wide reel for posters of 2 m2.

In addition, the second support 3B is movable by being controlled by the control system S to adjust the parallelism of the width of the unwound sheet, as will be seen later.

The supply and support means 3 'of the unrolled spool at the height of the working plane P are immediately placed downstream of the support means 3. The feed and support means 3' comprise a roller parallel to the axis Y, longer than the width of the coil 2, and located at the height of the plane P.

The driving / unwinding and pulling means 4 of the reel allow the sheet of the reel to be pulled to unwind and advance it from upstream to downstream. They are placed towards the downstream end of the machine, being arranged immediately upstream of the transverse cutting means 9A and deposition means 9B zip and deposit 9C of reinforcing adhesive on the zip.

The traction means 4 comprise a roller 40 which is motorized. This motorized roller 40 extends parallel to the Y axis and is arranged so that its upper surface is tangential to the plane P. It is motorized so as to rotate in the trigonometric direction to tow the upstream sheet downstream.

The driving and pushing means 4 'of the unwound sheet contributes to the advancement of the sheet and especially to its thrust once the transverse cut along the Y axis has taken place. The drive and thrust means 4 'comprise a motorized thrust roller 41 extending along the Y axis and located at the right of the traction roller 40, and cooperating with it by rotating in the opposite direction.

The unrolled sheet is pinched between the pull roller 40 and the push roller 41 to ensure, once the upstream poster 2A has been cut and processed and the top edge of the next poster 2B has been processed concomitantly while being still attached to the sheet, to continue advancing the next sheet downstream of the machine.

Preferably, the traction roller 40 and the thrust roller 41 have their peripheral surface coated with a material promoting both adhesion and traction of the sheet, for example rubber.

The means / bearing surfaces 5 of the unwound sheet at the level of the work plane P are arranged downstream of the supply and support means 3 'and upstream of the traction means 4.

The bearing surfaces 5 make it possible to arrange the sheet flat over a short portion of direction X to operate on (the upper face of) the unrolled sheet, in particular to affix the marking elements 24 on one of the lateral edges of the sheet , and if necessary the side reinforcing adhesives 23A and 23B. The bearing surfaces 5 comprise two longitudinal first cylinders 50 and 51 extending parallel to the Y axis, close to each other, and arranged at the height of the plane P, so that the sheet rests on their surface upper peripheral to be flat when the marking elements 24 are deposited remotely via the deposition device 8.

The marking elements 24 are deposited in line with the rolls 50 and 51 via the deposition device 8 continuously.

In addition, the bearing surfaces 5 comprise an additional cylinder 52 downstream of the first cylinders 50 and 51, and at which are deposited the lateral reinforcing adhesives. The deposition devices 8A and 8B of the lateral adhesives are arranged on each lateral edge of the machine vertically to the additional cylinder 52 and are retractable between an active low position of cooperation with the surface of the cylinder (the plane P) and therefore the unwrapped sheet, and an inactive high position above the plane P, to respectively ensure or not the deposition of the adhesive. The deposit operation is performed continuously, while the sheet 2 scrolls.

The deposition devices 8A and 8B of the lateral adhesives are in themselves known. They are also able to be translated along the Y axis to be positioned appropriately, before the beginning of the application of the adhesive, facing the desired deposition surfaces of the sheet along the width of the sheet. They each comprise an application roller 80.

With reference to FIGS. 3a and 3b, the rollers 60 to 62 contribute to the smooth running of the coil. They are retractable between a high position located above the plane P (Figure 3a) and a low position (Figure 3b) located below the plane P. The high position ensures the flat passage of the sheet at the start during the initial and manual unwinding of the reel before the automated start of the machine.

The manually unrolled sheet then rests as shown in FIG. 3a on the support roll 3 ', the support rollers 50 to 52, and the motorized traction roll 40. Then, by keeping the unrolled sheet in position, in particular by now the downstream end of the sheet via the suction means 11 of the support table 30, the rollers 60 to 62 are toggled in the down position to support in a controlled manner on the unwound sheet (Figure 3b). The unwound sheet then cooperates with the lower peripheral surface of the rollers 60 to 62 to go up after each roller to the plane P. The actuation of the retraction of the rollers is carried out by the control system S. It can by example to trigger in response to a manual command from the operator.

The automated unwinding can begin as well as the different preparation operations. The aspiration of the sheet 2 'is cut off as soon as the scrolling starts.

The first loading roller 60 is isolated between the support roller 3 'and the support rollers 50 and 51. This first loading roller 60 is part of the control means 6 of the unwinding of the coil as described. later.

The second roller 61 interengages with the additional support cylinder 52 being placed immediately upstream and below thereof, to ensure the passage of the sheet from the lower surface of the second roller 61 up to to the upper surface of the additional support cylinder 52.

The third roller 62 engages with the traction roller 40 being arranged immediately upstream (offset vertically upstream) and below, to ensure the passage of the sheet from the lower surface of said third roller. 62 to the upper surface of the traction roller 40.

The second and third rollers 61 and 62, and the thrust roller 41 are preferably mounted on a common frame 63 adapted to be displaced in translation along an inclined axis 64 positioned under the plane P, the displacement being activatable by pneumatic means 65. The drive rollers 61 and 62 and thrust rollers 41 are positioned ad hoc on the frame to be arranged above the plane P in the high position of the frame, and after translation of the frame, to be placed below the plane P by cooperating respectively with the support cylinder 52 for the second roll-up roll 61 and the traction roller 40 for the third roll-up roll 62 and thrust 41.

Advantageously, the depositing devices 8A and 8B are also embarked on the frame 63 so that their application roller 80 cooperates with the right of the support cylinder 52 in the lower position of the frame.

The regulation means 6 of the unwinding of the coil allow a smooth and uniform unwinding of the coil and without excessive tension. They act on the tension imposed on the sheet upstream of its unwinding so that the sheet is stretched appropriately to prevent on the one hand any wrinkling, and on the other hand stretching too tight the sheet otherwise risking tearing last. The regulating means 6 are arranged just downstream of the feed and support means 3 'and upstream of the bearing surfaces 5 (the first bearing cylinders 50 and 51). By way of a preferred example, the regulation means 6 consist of a motorized regulation puppet which is a device known per se for controlling unwinding of a reel. The puppet is able to pivot about a median horizontal axis so that its swiveling downstream end 60, which advantageously corresponds to the first landing cylinder, cooperates with the sheet 2 'to press on it and to go more or less down the sheet below the plane P in order to adjust the tension of the sheet between the support roller 3 'and the first support cylinder 50 at the height of the working plane P, and finally ensure that the traction of the unrolled sheet does not pull on the spool 2.

The motorized regulating puppet 6 is controlled by the control system S. The control / control of the tension of the sheet is effected by the control system S in response to receiving the measurement of the angle of the puppet via a potentiometer.

The detection means 7 are arranged immediately downstream of the first support cylinders 50 and 51. They detect the edge of the sheet, the marking elements 24, and the marking / separation lines 20 and 21 of the visuals. The data measured by the detection means 7 are processed by the control system S which in response: - controls the deposition of the marking elements 24 in the ad hoc places by the deposition device 8, - controls the deposition of the lateral reinforcing adhesives 23A and 23B by the depositing devices 8A and 8B, - controls the momentary stops and resumes of scrolling and unwinding for the implementation of the cross-section means 9A and deposition means 9B of zip and 9C of reinforcing adhesive , - corrects a possible defect of separation of the edge with respect to the lateral edge of the machine (by sending a movement order to the movable support 3B).

In response to the measurement of the edge of the sheet, the system S controls the movable support 3B to translate it to the right or left of the machine to adjust the parallelism of the width with the direction X scroll.

The unwound sheet 2 'must be cut, if necessary, at its lateral edges, in particular for the large widths, and sometimes cut in half, for example in the direction of travel, to divide the width in two and separate two adjacent visuals (side by side on the width). In this regard, the cutting means 9 and 9 'of the lateral edges, and the intermediate cutting means 9 "are arranged to cut from the lower surface of the sheet and to the right of the second roll-up roller 61, downstream means 7 and 8B, the lateral cutting means 9, 9 ', and intermediate 9 "each comprise a motorized cutting wheel, rotating at the same speed as the roller speed 7 and immediately upstream of the deposition of the lateral reinforcing adhesives 8A and 8B. traction 40, and able to be translated in height, for example by pneumatic means, to cooperate or not with the sheet. The lateral cutting means 9, 9 'and intermediate 9 "are controlled by the control system S. Moreover, the cutting means are either limited in number, as here illustrated in number of five including the three intermediate 9 are capable of being displaced in translation along the Y axis to be positioned at the right of the cuts to be made according to the width of the width, or are fixed with respect to the Y axis and their number is a function of the different widths that can be processed the machine.

In the last cut made by the machine, the transverse section means 9A cut the sheet 2 'parallel to the Y axis to separate the visual individual posters, according to the lines 20 and 21. This operation is done by temporarily stopping scrolling. Following this transverse cut, the deposition means 9B zip and possibly the application means 9C reinforcing adhesive on the zip fastening strip are immediately implemented. Advantageously, the transverse section means 9A, and the deposition means 9B zip and the application means 9C reinforcement adhesive, are carried by a common support 90A mobile along a gantry 90 which is disposed beyond above the work plane P and parallel to the axis Y. While the scrolling is stopped, the support 90A is adapted to be translated along the Y axis, each of the cutting means 9A, and 9B zip depositing means and applying adhesive 9C being implemented consecutively. In this respect, they are arranged linearly on the common support 90A by being positioned one after the other. They are intended to be applied against the sheet by translation of the common support 90A along the entire length of the web. In addition, at least the adhesive application means 9C are operable in a vertical plane to be brought into the same horizontal plane as the cutting means 9A and 9b zip deposit, if they are to be implemented in following these.

The transverse cut is made from the upper surface of the unwound sheet 2 'at the two registration lines 20 and 21 in the stopped position of the sheet. The cutting means 9A comprises two cutting wheels 91 and 92 (FIG. 3a) which are spaced a distance corresponding to the spacing of the marking lines 20 and 21. In FIG. 3a, the cutting wheels 91 and 92 are not activated yet.

To support the sheet unrolled flat in the plane P during cutting operations, zip fastening and application of reinforcing adhesive, the machine 1 comprises the support table 10 which is advantageously provided with suction means 11 to maintain in place on the one hand the cut down portion of the sheet and corresponding to the individual poster 2A and on the other hand the upstream portion 2B of the sheet corresponding to the next visual of the next poster to be cut. In addition, the support table 10 is in two parts, a fixed upstream portion 10A and a downstream portion 10B adapted to be movable in translation in the X direction to deviate from the upstream portion just before the cutting and deposition operations zip, and possibly reinforcing adhesives. The opening of the table makes it possible to provide a slot 10C (FIG. 3b) whose width in the X direction corresponds to a little less than the separation distance of the registration lines 20 and 21. The cutting wheels 91 and 92 act the lines 20 and 21 which are located respectively on the downstream part of the sheet intended to correspond to the poster 2A and maintained by the downstream part 10B of the table, and the upstream part of the sheet intended to become the shows 2B and held in place on the upstream portion 10A of the table. Once the strip is cut, the cutting edge falls by gravity through this slot 10C. The cut can be evacuated by the suction means 12 arranged under the slot 10C. Cutting wheels

Preferably, the deposition means 9B zip are as already explained embedded with the cutting means 9A on the unitary support 90A being offset along the axis Y. The implementation of the unitary support 90A generates the operation of fixing the zip immediately after cutting, then follow if necessary the deposit of adhesives. Only the 90A unit support is to be ordered. The implementation of the support 90A is performed by the control system S.

With reference to FIG. 3b, the deposition and fixing means 9B of the zip comprise two depositing rollers 93 and 94 which are arranged above the plane P and spaced apart by a distance adapted to the fixing of the bottom zip 25B of the poster downstream 2A and the top zip 25A of the next poster 2B (still secured to the sheet 2 '), and able to be applied concomitantly against the upper face and the edges of the respective posters 2A and 2B by traversing the entire length of the width of the posters. When the zip is applied, the table 10 is always divided in two and the suction means 11 are still in operation for the plating of the posters. The means of deposit and zip fastening are not further described because known per se in their operating principle. A magazine 95 for the zip is provided next to the machine 1 to automatically feed the two deposit rollers 94 and 95.

If necessary, the deposition means 9C of the reinforcing adhesive on each of the zip fastening strips can be implemented. These deposition means comprises two application rollers including a roller 96 visible in FIG. 7, which are spaced from the appropriate distance to cooperate with the fastening strips of the bottom zip 25B of the downstream poster 2A and the top zip 25A of the following poster 2B. These depositing means are in themselves known in their operating principle. As soon as the operations of cross section, zip deposit and possibly deposition of reinforcing adhesive are completed, the table 10 is closed and scrolling starts again. The closure of the table is necessary to allow the passage of the upper part of the following poster 2B, which has been prepared to the top of the movable part 10B of the table. The reopening of the table to operate on the lower part of the following poster 2B is done in masked time.

After treatment of the bottom edge of the upstream poster 2A (and concomitant with the treatment of the top edge of the next poster 2B), the upstream poster 2A becomes individual is evacuated by the evacuation means 13 comprising for example by a system of blowing arranged under the mobile table 10B and blowing air upwards and downwardly inclined to the machine.

The individual posters are either removed individually to be stored flat or rolled up later, individually or in groups, or directly wound at the end of the machine with the winding system 14 arranged after the downstream end of the movable portion 10B of the support table 10 and parallel to the Y axis (thus perpendicular to the X axis scroll).

The individual posters are rolled parallel to their width, that is to say parallel to the longitudinal axis of the zip.

When all the coil 2 has been processed to deliver individual posters all prepared, another coil may be intended to be installed. In order to avoid having to retract in the high position the loading rollers 60 to 62 and manually draw the beginning of the other coil and repeat the operations of setting up the unrolled sheet before actuating the automated unwinding, the machine 1 preferably comprises the connecting table 33 which is arranged immediately after the upstream support roll 3 'and before the regulation puppet 6. This connection table 33 is suction to hold in place the end of the unrolled sheet of the first reel and the beginning of the unrolled sheet of the second reel. The second spool is loaded on the support means 3 of the machine having previously removed the first empty spool, and is unrolled above the support roller 3 'and the suction connection table 33.

Above the connection table 33 is provided a connection device 34 able to move parallel to the Y axis and possibly comprising cutting means on each edge of the end of the first coil and the beginning of the second coil to ensure perfect parallelism of the edges, and gluing means for bonding the two respective end edges of the first and second spools. The connection is thus automated.

The implementation of the machine 1 of the invention for preparing individual posters from the spool 2 is as follows: a) the operator installs the spool 2 on the support means 3 and manually unwinds the start of the spool to engine the sheet in the machine; b) while the regulation puppet 6 and the frame 63 are in the up position, the operator unrolls the beginning of the reel by passing the sheet 2 'on the support roll 3', the support rollers 50 to 52 , and the pull roller 40 to position the downstream end of the sheet on the moving table portion 10B while the suction means 11 are active; c) once the sheet is positioned, the operator actuates a button to confirm the activation of the control system S; d) the engagement of the machine causes the translation of the frame 63 in the low position and the pivoting in the lower position of the puppet 6, then once the low positions are reached, the scrolling of the sheet 2 'and the unwinding of the reel 2 are activated; there will be a loss at the start e) the detection means 7 allow via the data processing by the control system S, in particular from the detection of the first registration lines 20 and 21, to continuously trigger upstream downstream at the appropriate times, the affixing of the marking elements 24 by the associated deposition device 8, the cutting of the lateral edges of the sheet by the cutting means 9 and 9 'and then the deposition of reinforcing adhesive on the edges laterally by the deposition devices 8A and 8B, and finally the momentary stopping of the movement which corresponds to the appropriate positioning of the marking lines 20 and 21 to the right of the common support 90A of the transverse section means 90A, and deposition means 9B of zip and 9C reinforcement adhesive; f) the momentary stopping engenders the aspiration of the table 10, its opening, and the translation of the common support 90A to finalize the processing operations, namely to cut the sheet according to the lines 20 and 21, to fix the zip and possibly the reinforcing adhesive; g) the table 10 is closed and scrolling resumes; h) once the support 90A has arrived at the end of the race, the individual downstream processed poster is evacuated and the scrolling of the sheet resumes; i) the operations e) to h) are repeated until the end of the unwinding of the coil.

Throughout the scrolling, the data acquired by the detection means 7 are also processed to possibly correct in response a drift of the width and act on the mobility of the support 3B of the coil.

Therefore, the automated machine of the invention allows itself to perform all the operations of preparing a printed sheet of printed visuals to turn it into individual posters ready for use and able to be wound for their packaging and their transport parallel to the assembly zip they have.
