Abstract

The envelope blank (6) is taken from an opaque band by cutting along lines (6A) perpendicular to its edges (1C,1D) to form a series of identical modules (6B). Each envelope is made by folding flaps (5) of the blank along lines (5A) parallel to opposite sides of the document (2). An imprint and a window (4) are made on one of the external and internal faces. The longitudinal position of an index (8) is defined and memorised relative to one of the longitudinal and transverse positions of the impression and window. Then the impression is made on one of the band faces (1A,1B), sequentially on each module. The index is marked on each different module along a longitudinal step (P1) equal to the spacing (E) of the cutting lines . Finally the position of the index is detected and relative to it a cut (4A) for each window is made followed by fitting of the screen (4B).

Description

L'invention se rapporte à un procédé pour la préparation d'un matériau opaque en bande, destiné à la confection en série d'enveloppes à fenêtre autour de documents.The invention relates to a process for the preparation of an opaque strip material, intended for the mass production of window envelopes around documents.

L'invention concerne également :

  • le matériau opaque en bande qui, destiné à la confection en série d'enveloppes à fenêtre autour de documents, est préparé selon le procédé indiqué et,
  • l'installation pour la mise en oeuvre du procédé.
The invention also relates to:
  • the opaque strip material which, intended for the series production of window envelopes around documents, is prepared according to the indicated process and,
  • the installation for implementing the method.

L'invention intéresse également l'installation comprenant les moyens pour la réalisation d'un tel matériau en bande selon le procédé indiqué.The invention also concerns the installation comprising the means for producing such a strip material according to the method indicated.

L'invention s'applique, particulièrement mais non limitativement, à l'industrie de l'emballage en grande série de documents destinés à être transmis par voie postale ou autres.The invention applies, particularly but not limited to, the packaging industry in large series of documents intended to be sent by post or otherwise.

Un résultat que l'invention vise à obtenir est un procédé de préparation du type précité qui soit d'une grande souplesse d'utilisation c'est à dire à même d'absorber les variations affectant différents paramètres de séries successives de documents à emballer, telles :

  • l'encombrement du document,
  • la position, la géométrie et les dimensions de la fenêtre, et
  • l'impression que doit porter l'enveloppe.
One result which the invention aims to obtain is a preparation process of the aforementioned type which is very flexible in use, that is to say capable of absorbing variations affecting different parameters of successive series of documents to be packaged, such:
  • the size of the document,
  • the position, geometry and dimensions of the window, and
  • the impression the envelope should have.

Un autre résultat que l'invention vise à obtenir est un matériau en bande qui permette d'assurer notamment :

  • la protection effective du document à transmettre,
  • la présentation de ce document à son destinataire, et
  • l'adressage personnalisé du dit document.
Another result which the invention aims to obtain is a strip material which makes it possible in particular to ensure:
  • effective protection of the document to be transmitted,
  • the presentation of this document to its recipient, and
  • the personalized addressing of said document.

A cet effet, l'invention a pour objet un procédé du type précité notamment caractérisé en ce que :

  • lors d'une première série d'étapes :
    • . d'une part, on définit la position longitudinale d'un index par rapport à au moins l'une des positions relatives longitudinales et transversales des différents éléments que sont chaque impression, chaque fenêtre, et les bords longitudinaux et transversaux du module et, d'autre part, on mémorise cette position,
  • lors d'une seconde série d'étapes :
    • . au niveau d'un premier poste de traitement, tandis qu'on imprime au moins l'une des faces de la bande en réalisant séquentiellement l'impression de chaque module, on marque chacun des différents modules de l'index, et ce, en disposant les index des modules selon un pas longitudinal, égal à l'écartement des lignes de découpe,
    • . au niveau d'un second poste de traitement, on détecte la position de chaque index et, relativement à cet index, on réalise le dépôt d'une substance adhésive dans deux zones qu'on situe transversalement à la bande et au niveau des lignes de découpe, et
    • . au niveau d'un troisième poste, on détecte la position de chaque index et, relativement à cet index, on réalise la découpe de chaque fenêtre, qu'on équipe ensuite d'un écran.
To this end, the subject of the invention is a method of the aforementioned type, in particular characterized in that:
  • during a first series of steps:
    • . on the one hand, the longitudinal position of an index is defined with respect to at least one of the longitudinal and transverse relative positions of the different elements that are each print, each window, and the longitudinal and transverse edges of the module and, d on the other hand, we memorize this position,
  • during a second series of steps:
    • . at a first processing station, while at least one of the faces of the strip is printed by sequentially printing each module, each of the different modules of the index is marked, and this in arranging the indexes of the modules in a longitudinal pitch, equal to the spacing of the cutting lines,
    • . at a second treatment station, the position of each index is detected and, relative to this index, an adhesive substance is deposited in two zones which are located transversely to the strip and at the level of the lines of cutting, and
    • . at a third station, the position of each index is detected and, relative to this index, each window is cut, which is then fitted with a screen.

L'invention a également pour objet le matériau en bande traité selon le procédé précité ainsi que l'installation comprenant les moyens pour la mise en oeuvre du dit procédé.The subject of the invention is also the strip material treated according to the aforementioned method as well as the installation comprising the means for implementing the said method.

Cette invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : l'une des deux faces opposées du matériau en bande de l'invention,
  • figure 2 : vue en coupe transversale, une enveloppe réalisée à partir du matériau représenté à la figure 1,
  • figure 3 : un schéma synoptique du procédé de l'invention.
This invention will be clearly understood with the aid of the description below given by way of nonlimiting example with regard to the appended drawing which schematically represents:
  • FIG. 1: one of the two opposite faces of the strip material of the invention,
  • FIG. 2: cross-sectional view, an envelope made from the material shown in FIG. 1,
  • Figure 3: a block diagram of the method of the invention.

En se reportant au dessin, on voit un matériau opaque en bande 1, destiné à la confection d'enveloppes 3 à fenêtre 4 autour de documents 2 qui présentent chacun au moins une face 2A inscrite dans un quadrilatère, notamment, sensiblement rectangle.Referring to the drawing, an opaque strip material 1 is seen, intended for making envelopes 3 with window 4 around documents 2 which each have at least one face 2A inscribed in a quadrilateral, in particular, substantially rectangle.

Chaque enveloppe 3 présente deux faces externes opposées 3A, 3B qui sont apparentes et deux faces internes 3C, 3D destinées à être tournées vers le document 2.Each envelope 3 has two opposite external faces 3A, 3B which are visible and two internal faces 3C, 3D intended to be turned towards the document 2.

Egalement, chaque enveloppe 3 présente, sur au moins l'une de ses faces externes et internes 3A à 3D, d'une part, au moins un graphisme (non représenté) réalisé par impression et, d'autre part, au moins une fenêtre 4 constituée d'une découpe 4A réalisée dans son matériau constitutif et un écran transparent 4B qui obture la dite découpe 4A.Also, each envelope 3 has, on at least one of its external and internal faces 3A to 3D, on the one hand, at least one graphic (not shown) produced by printing and, on the other hand, at least one window 4 consisting of a cut 4A made of its constituent material and a transparent screen 4B which closes said cut 4A.

Par graphisme, on désigne notamment aussi bien les caractères d'un texte qu'un dessin au trait, qu'une photographie.By graphics, we mean in particular as well the characters of a text as a line drawing, as a photograph.

Outre deux extrémités dont une seule est représentée, la bande 1 présente deux faces opposées 1A, 1B ainsi que deux rives 1C, 1D sensiblement parallèles.In addition to two ends, only one of which is shown, the strip 1 has two opposite faces 1A, 1B as well as two substantially parallel edges 1C, 1D.

Les enveloppes 3 sont constituées par repliement de volets 5 d'un flan 6 de matériau opaque, selon des lignes 5A sensiblement parallèles à des cotés opposés 2B, 2C du document 2 et approximativement parallèles aux rives 1C, 1D de la bande 1.The envelopes 3 are formed by folding shutters 5 of a blank 6 of opaque material, along lines 5A substantially parallel to opposite sides 2B, 2C of document 2 and approximately parallel to the edges 1C, 1D of the strip 1.

Les volets 5 peuvent évidemment être de largeurs différentes.The flaps 5 can obviously be of different widths.

Les flans 6 sont prélevés dans la bande 1 par découpe selon des lignes 6A globalement perpendiculaires à ses rives 1C, 1D.The blanks 6 are taken from the strip 1 by cutting along lines 6A generally perpendicular to its edges 1C, 1D.

Les bords du flanc 6 constitués par découpes selon les lignes 6A matérialisent ses bords transversaux du flanc 6 et ses bords transversaux sont quant à, eux, réalisés chacun par un segment d'une rive de la bande.The edges of the sidewall 6 formed by cutouts along the lines 6A materialize its transverse edges of the sidewall 6 and its transverse edges are each produced by a segment of an edge of the strip.

On comprend aisément que c'est la dimension longitudinale du flan 6 qui détermine l'écartement E des lignes 6A de découpe.It is easily understood that it is the longitudinal dimension of the blank 6 which determines the spacing E of the cutting lines 6A.

Préalablement à leur découpe selon les lignes transversales 6A, les flans 6 constituent donc sur la bande 1 une succession de modules 6B identiques préparés selon le procédé de l'invention.Prior to their cutting along the transverse lines 6A, the blanks 6 therefore constitute on the strip 1 a succession of identical modules 6B prepared according to the method of the invention.

Pour chaque module 6B d'un même ensemble de modules 6B, les positions relatives de l'impression, d'au moins une fenêtre et des bords longitudinaux et transversaux du module, sont précisément définies et, notamment, paramètrées.For each module 6B of the same set of modules 6B, the relative positions of the printing, of at least one window and of the longitudinal and transverse edges of the module, are precisely defined and, in particular, parameterized.

De manière remarquable, pour préparer le matériau en bande 1 en vue de la réalisation d'enveloppes 3 à fenêtre 4 :

  • lors d'une première série d'étapes :
    • . d'une part, on définit la position longitudinale d'un index 8 par rapport à au moins l'une des positions relatives longitudinales et transversales des différents éléments que sont chaque impression, chaque fenêtre, et les bords longitudinaux et transversaux du module et, d'autre part, on mémorise cette position,
  • lors d'une seconde série d'étapes :
    • . au niveau d'un premier poste 7 de traitement, tandis qu'on imprime au moins l'une des faces 1A, 1B de la bande 1 en réalisant séquentiellement l'impression de chaque module 6B, on marque chacun des différents modules 6B de l'index 8, et ce, en disposant les index 8 des modules 6B selon un pas longitudinal P1, égal à l'écartement E prévu pour les lignes 6A de découpe,
    • . au niveau d'un second poste 9 de traitement, on détecte la position de chaque index 8 et, relativement à cet index 8, on réalise le dépôt d'une substance adhésive dans une zone 10 qu'on situe transversalement à la bande et au niveau de chacune des lignes 6A de découpe qui délimitent le modèle 6B,
    • . au niveau d'un troisième poste 12, on détecte la position de chaque index 8 et, relativement à cet index 8, on réalise la découpe 4A de chaque fenêtre 4, qu'on équipe ensuite d'un écran 4B.
Remarkably, to prepare the strip material 1 for the production of envelopes 3 with window 4:
  • during a first series of steps:
    • . on the one hand, the longitudinal position of an index 8 is defined with respect to at least one of the longitudinal and transverse relative positions of the different elements that are each print, each window, and the longitudinal and transverse edges of the module and, on the other hand, we memorize this position,
  • during a second series of steps:
    • . at the level of a first processing station 7, while at least one of the faces 1A, 1B of the strip 1 is printed by sequentially printing each module 6B, each of the different modules 6B of l is marked 'index 8, and this, by placing the indexes 8 of the modules 6B according to a longitudinal pitch P1, equal to the spacing E provided for the cutting lines 6A,
    • . at a second treatment station 9, the position of each index 8 is detected and, relative to this index 8, an adhesive substance is deposited in a zone 10 which is located transversely to the strip and to the level of each of the cutting lines 6A which delimit the model 6B,
    • . at a third station 12, the position of each index 8 is detected and, relative to this index 8, the cut 4A of each window 4 is made, which is then fitted with a screen 4B.

De préférence, la substance adhésive est du type adhésvie à froid par pression.Preferably, the adhesive substance is of the cold pressure adhesive type.

De préférence, au niveau d'un quatrième poste 13, on enroule la bande 1 ainsi préparée, de manière à constituer une bobine 14.Preferably, at a fourth station 13, the strip 1 thus prepared is wound up, so as to constitute a coil 14.

C'est cette bobine 14 qui sera reprise pour être traitée sur une machine (non représentée) d'emballage de documents 2.It is this coil 14 which will be taken up to be processed on a document packaging machine (not shown) 2.

Le respect de ce procédé permet d'obtenir le résultat annoncé pour l'invention à savoir un procédé de préparation du type précité dont la souplesse d'utilisation est à même d'absorber les variations qui peuvent affecter différents paramètres de séries successives de documents à emballer, telles :

  • l'encombrement du document,
  • la position, la géométrie et les dimensions de la fenêtre, et
  • l'impression que doit porter l'enveloppe.
Compliance with this process makes it possible to obtain the result announced for the invention, namely a preparation process of the aforementioned type, the flexibility of use of which is capable of absorbing variations which may affect different parameters of successive series of documents to be pack, such:
  • the size of the document,
  • the position, geometry and dimensions of the window, and
  • the impression the envelope should have.

De manière remarquable, lors de la réalisation au niveau dudit second poste 9 de traitement, du dépôt d'une substance adhésive à froid dans une zone 10 qu'on situe transversalement à la bande et au niveau de chacune des lignes 6A de découpe, on réalise l'application de la substance adhésive dans une surface 10 qui s'étend transversalement à la bande 1 sur toute sa largeur, et ce, sur une largeur L1, L2 déterminée, de part et d'autre de chaque ligne 6A de découpe.Remarkably, during the production at said second treatment station 9, of the deposition of an adhesive cold substance in a zone 10 which is located transversely to the strip and at each of the cutting lines 6A, performs the application of the adhesive substance in a surface 10 which extends transversely to the strip 1 over its entire width, and this, over a determined width L1, L2, on either side of each cutting line 6A.

Le respect de ces particularités de procédé vise à l'obtention du second résultat annoncé pour l'invention à savoir, un matériau en bande qui permette d'assurer notamment :

  • la protection effective du document à transmettre,
  • la présentation de ce document à son destinataire, et
  • l'adressage personnalisé du dit document.
Compliance with these process particularities aims to obtain the second result announced for the invention, namely, a strip material which makes it possible in particular to ensure:
  • effective protection of the document to be transmitted,
  • the presentation of this document to its recipient, and
  • the personalized addressing of said document.
