Abstract

The format obtained by this process comprises a base sheet (2) and several separable labels (11a, 11e). The best ones (12a, 12f and 13a to 13f), which vary from one format to another, are applied to these elements. In each format, these variable messages must necessarily be identical. This requirement is satisfied by printing the variable messages at the same time on the first and the same paper web and by folding the intended longitudinal strip to form the sheets on that intended strip to form the labels. The messages of the first and the same format are therefore necessarily coincident

Description

V PROCESS FOR MANUFACTURING FORMATS AND FORMAT OBTAINED THROUGH THIS PROCESS The present invention relates to the manufacture of composite formats of a sheet and of at least one peelable part forming a self-adhesive label. Frequently, there is a need to be able to ~ F / t identify items, for example by a number, a code of bars or similar and transfer this information to other documents making this possible, for example, when carrying out tasks that are related to the handling of items, such as storage, registration in the accounting system, your name in the shipment of a note, etc.

Conventionally, such information was transferred by hand over documents related to the article, an operation that was often subject to copy errors. Some time ago, more suitable formats were created, including these a base sheet to which it is attached optionally at least one different sheet that can be separated, and on the base sheet of which are several self-adhesive labels that can be easily peeled off. Each of these labels carries the same identification information, such as an uncoded number and / or a bar code, the base sheet also carries the same information. Under these conditions, the base sheet can be attached to the article and the labels can serve as elements to identify the article, which can then be stuck on other documents that serve, for example, for the management of the article from the storage and accounting points of view. Another application of these formats is their use in a medical analysis laboratory, each sample of a patient, identified by a format, has to be divided into several samples to be examined which can then be accurately identified by attaching to each sample a label from the same and the same format. Said format can in this way comprise various information data, such as numbers, signs individuals, addresses, information data for the identification of the articles on which they are stuck, etc. This information data or "messages" can be called "fixed messages" and "variable messages", a piece of information that, in a given series of formats, does not change from one format to another is called a "fixed message", while a "variable message" is different for each format of the same series. These messages must be printed both on the base sheet of the format and on the self-adhesive labels and possibly also in other sheets, if this is a format that constitutes a game comprising several additional separable sheets. According to an example of an ordinary process for the manufacture of these formats, a first strip of a siliconized support material is taken, on the first strip of which an adhesive is deposited, and a second strip of paper. This complex of two strips provided with adhesive is then printed to the recto and verso with fixed and / or variable messages. If the variable messages are to be printed on both the recto and verso, two separate printing steps are therefore necessary for printing. Then, in order to obtain self-adhesive labels, it is necessary to cut them out of the paper strip. The formats can then be delimited from one another by perforation lines that extend transversely with respect to the overlapping strips and the product obtained can be packaged as a folded concertina assembly or as a reel. During use, the labels can thus easily be separated from the siliconized support. During the printing operation, of course it is important that the variable messages printed to the recto coincide in the longitudinal direction with the same variable messages printed to the verse so that, after printing, they can be found, on a region that corresponds to a given form, the same variable messages on all the elements of the format to the recto and to the verse. However, they are flipped so that the agreement of the variable messages on the recto and the verse of the folded concertina complex or on the reel require constant verification during the second printing step. This verification work can be done at a reasonable cost only if the verifier reviews only the beginning and end of the complex, the verification operation is extremely costly if the verifier has to review each format in the complex. However, the case of non-concordance of the variable messages between the beginning and the end of the complex can also be presented. The object of the invention is to remedy the drawbacks of the prior art mentioned above and to avoid any need to correct the mismatched errors of the variable messages on the various elements of the formats to the recto and to the verse. Therefore, the subject of the invention is a process for the manufacture of formats of the type comprising a base sheet to which at least one detachable label is attached, by means of a layer of silicone and a layer of adhesive, those cited layers being superimposed, said sheet and said label being each provided with at least one so-called variable message that differs from one format to another, this process is characterized in that - a) an elongated band of paper or paper is prepared. similar material; - b) is printed on one side of this band and in each region corresponding to a format at least as much the variable message intended for said sheet of LE. this format as at least the intended variable message for said label of this format, the two variable messages being separated in the transverse direction of said band, the two longitudinal strips, assigned respectively to the sheets of the formats and to the labels of the last, being materialized on said band; fifteen - . 15 - c) at least one layer of silicone and at least one layer of adhesive are deposited on the side of said opposite band carrying said variable messages • * in the place where said label has to be attached to said band; 20-d) and one of said strips is turned over the other strip in order to superimpose the strip assigned to the labels and said layers of silicone and adhesive, this makes it possible to carry out operations a), b) and c ) in any order.

By virtue of these characteristics, due to the fact that the printing of the variable messages takes place in one and in the same band of paper and that, when one of the longitudinal strips is turned over the other strip longitudinal, these messages can be maintained in perfect correspondence in the longitudinal direction and each format will always carry identical identical messages in the two strips. Therefore there is no possibility of having an error F, in the coincidence of these messages. The subject of the invention is also to obtain a format by the process such as that newly defined. Other features and advantages of the invention will appear in the course of the description that follows, being given only by way of example and with reference to the accompanying drawings wherein: - Figure 1 is a perspective view of a format produced using the process according to the invention; - Figure 2 is also a perspective view 20 of the format according to the invention, some of its elements being partially separated from it, while the others are revealed by a cut; - Figure 3 is a partial sectional view of a format according to the invention; ^ W - Figure 4 illustrates, through a highly diagrammatic perspective view, certain operations performed during the implementation of the manufacturing process according to the invention; 5 - Figure 5 is a highly diagrammatic elevation view of a plant for implementing the process according to the invention; and - Figure 6 is a highly diagrammatic view IjÜ illustrating an alternative format for implementing the process according to the invention. Figures 1 to 3 will all be described first, showing these, only on an example way, a format that can be produced using the manufacturing process according to the invention. It is represented by the reference General 1. The entire first format 1 comprises a base sheet 2 * which can be produced from any material in the form of a strip, such as a suitable mechanical grass paper, a kraft paper or possibly a plastic film. United a In this base sheet 2 the additional sheets 3 and 4 can be mounted in a peelable form on the base sheet 2, for example by their side edges, the sheet 4 in this example constitutes the upper part of the format. Said additional sheets may also be provided below the other side of the sheet.

The margins 5a and 5b may have Caroll-like perforations 6, well known in the art for the transportation of a series of shapes that are joined together by the perforated lines 7 and may be separated along these perforated lines. The side of each sheet with the face up in Figure 1 will be called straight and the opposite side will be called verse. The verse of the base sheet 2 is divided into two regions 2a and 2b. The two regions 2a and 2b can carry printed information formed by the variable and fixed messages in the sense in which these terms are explained below in the present. In region 2a of the base sheet, the verse of the latter carries a layer of silicone 8. In the example described, this region occupies a little less than a quarter of the total surface area of sheet 2. However, it will be noted that the size of region 2 compared to that of the complete format is not critical and is only dictated by the requirements of using the format and by the fixed and variable messages that they must carry. The siliconized region 2b is covered, at least partially, with a skirt 9 which carries on its side facing the sheet 2 a layer of adhesive 10 by means of which the skirt 9 adheres to the base sheet 2. The area of this layer of adhesive 10 is slightly larger than that of the silicone layer 8, being further divided into several regions lia-lie corresponding to the perimetric cuts which, in this example, have a general rectangular shape. Each of these regions delimits a separable label. Only five of these regions are found by way of example. Of course, the arrangement of the silicone layer, the adhesive layer and the cuts may be around otherwise. All the sheets of the format include the skirt 9, they can carry a plurality of fixed messages previously printed non-encoded (not illustrated in the drawings) so that they form sectors, identification data, texts that relate to the use of the format, corporate name , etc. The format can also have various variable messages that differ from one format to another. Said message may first of all be an uncoded serial number (number 9 in the Figures), optionally and preferably, accompanied by an encoded identification that can be read by a machine, such as, for example, a bar code. These variable messages are presented several times on the format and, with respect to the serial number and the code, are necessarily identical for the same format. In the example shown, these variable messages are at least on the base sheet 2, on 12a (uncoded serial number) and 13a (bar code), and on the labels lia a lie, respectively on 12b to 12f and in 13b to 13f. In addition, the format includes messages identified 14a to 14e which are in fact fixed messages, since they are identical from one format to another but different within the same format. In the example shown, these fixed messages, which represent numbers 1 to 5, are serial numbers of the current labels of the format, allowing them to be distinguished from each other. Those skilled in the art will understand that, within the scope of the invention, a format may include a greater number of messages, whether they are fixed or variable, depending on the requirements of the use of the format. The invention is therefore not limited in any way by the nature of these messages or by their content or by their graphics or by other properties that may be optionally displayed. It is important to note that the format 1 according to the invention includes a base sheet 2 and a skirt 9 which are produced from the same material, this being an essential feature of the invention that will appear more clearly below or reading the description of the manufacturing process according to the invention.

A preferred embodiment of this manufacturing process will now be described with more particular reference to Figures 4 and 5. A web 15 of material, such as paper, paper kraft or possibly a plastic film, before everything is subjected to a printing process during which all the fixed and variable messages of the sheet 2 and the skirt 9 are provided thereon in a single printing step 'Ék on one and the same side of the band. Therefore this one has a slightly greater width corresponding to the total of the width of the sheet 2 and of the skirt 9 of a format. This procedure can be implemented using any known printing process, rotary printing is preferred. During this operation, each region of the band 15 corresponding subsequently to a format will thus comprise, side by side in the direction of the width, the messages on the recto of sheet 2 and those on the , verso of the skirt 9. During the printing of the band, this can be wound on a reel 16 (Figure 5) that can be transported or stored temporarily, waiting for the subsequent treatment. The reel 16 is placed in the plant to implement the process of the invention, wherein the band preprinted 15 will be unwound from it. Downstream of the position of the spool 16, the band will receive, on its opposite side to the printed side, firstly a layer with silicone (17, Figure 4) which is applied thereto by means of a nozzle 18 which is placed through the band 15 and has an outlet whose width corresponds to the width of the labels Ia a lie. It should be noted that, according to an alternative form, the silicone layer 17 can be fixed prior to printing, during printing, or as illustrated, after printing. Positioned downstream of the nozzle 18 is a nozzle 19 by means of which an adhesive layer 20 is deposited on the side of the strip 15 on which the silicone layer 17 only has to be deposited. This nozzle 19 is also placed through the band, but its outlet is offset transversely with respect to the outlet of the nozzle 18. Then, the band passes through a bending station. 21 equipped with three three rollers 21a, 21b and 21c, for example, allow the web to be folded longitudinally in such a way that the adhesive layer 20 covers the silicone layer 17, thereby forming a lateral fold 22 in the web. 15 (see also, in Figure 1, that part of format 1 is shown in dashed lines).

In order for the band 15 to be longitudinally folded satisfactorily, it is important that it be tensioned correctly from the reel 16. The plant comprises for this purpose, a device that lifts the paper, symbolized at 23 in Figure 5, which makes it possible to maintain the necessary tension in the band on the upstream side. Downstream of the rising station > | , paper 23, the band is optionally provided with toothed perforations of the Caroll 6 type, in both of their margins in a punching station symbolized in 24. For the margin of the side where the bend 22 is located these serrated perforations are placed inside a cutting line 25 (see Figure 1) whereby the fold 22 will be removed from the band 15. The cut can be carried out in a station 26 placed downstream of the punching station 24. Still downstream, the process subsequently consists in making a "semi-deep" cut in order to delimit the regions lia lie to the labels of the format 1. During this operation, the cutting blade will only cut the thickness of the skirt 9 to the corresponding side of the band 15, (which in Figures 4 and 5 is the upper side of the band 15 folded 25 longitudinally). The "semi-deep" cutting operation V is carried out in a station 27. In an alternative embodiment, where the format has only a single label, the incision operation is superfluous. Then, in a station 28, the additional sheets, such as the sheets 3 and 4 shown in Figures 1 to 3 can be attached to the strip 15. The latter is then provided with transverse perforation lines that extend between the forms (the station is not *, illustrated in the Figures), this makes it possible for these forms are detached from each other in order to be dispatched stacked or also remain attached in order to be dispatched by a reel or in the form of a folded concertina stack. From the detailed description before mentioned, it will be understood that the variable messages that were discussed before and that have been printed in perfect longitudinal coincidence on the split band until now, will preserve this longitudinal coincidence through all the subsequent operations, firstly due to that the band 15 is made as a single piece and then, after separating the fold 22, because after separating two strips from the band they will adhere to each other. A deviation in the variable messages in the longitudinal direction of the band is thus impossible, so each format is always provided with its correct variable messages. Figure 6 shows an alternative way of implementing the process of the invention having the advantage of being able to join the strip of the intended web to form the labels laterally at any point on another strip of the strip. Figure 6 shows a pre-printed band 15A, | Mt on the side not visible in the Figure, with fixed messages and variables as in the case of band 15 in Figures 4 and . First, this band undergoes a longitudinal cutting operation in a cutting station 30 by means of which a longitudinal incision is made in the band 15A. A strip 15A-a is thus formed, projected to form the base sheets 2 of the formats 1, and a strip 15A-b, which will form the flaps 9 thereof. Upstream of the incision station 30, a layer of silicone 32 is deposited having a width corresponding to that of the labels on that part of the band which will subsequently form the strip 15A-a. The latter passes through a flow regulation station 33, known per se, after which a layer of adhesive 34 is deposited on the strip superimposed with the silicone layer 32. 25? R The other strip 15A-b of the strip 15A is taken to a turning station 35 on which the strip is flipped, the printed messages are initially on the lower face of Figure 6, leaving, after they leave the station 35, on the upper part, the The strip is placed laterally so as to cover the layer of adhesive 34 deposited on the strip 15A-a. Station 35, slightly retards strip 15A-a jy with respect to strip 15A-b, allowing precise compensation 10 for the delay caused by the last passage through turning station 35. fifteen F > twenty
