Abstract
Description
La présente invention concerne un procédé et un dispositif pour la protection du blanchet d'une machine Offset lors de l'utilisation de filets perforants, de filets coupeurs ou analogues.The present invention relates to a method and a device for protecting the blanket of an offset machine when using perforating nets, cutting nets or the like.
On sait qu'un filet perforant se présente sous la forme d'une bande, généralement métallique, présentant un rebord latéral en saillie denté ou aiguisé dont la face opposée au rebord porte un revêtement adhésif initialement protégé par un ruban de protection que l'on retire au moment de l'utilisation.We know that a perforating net is in the form of a strip, generally metallic, having a lateral rim projecting toothed or sharpened, the face opposite to the rim carries an adhesive coating initially protected by a protective tape which remove at the time of use.
Ces filets perforants sont destinés à venir se coller sur le cylindre de marge qui vient normalement comprimer les feuilles à imprimer sur le blanchet.These perforating nets are intended to be stuck on the margin cylinder which normally compresses the sheets to be printed on the blanket.
En vue de faciliter la mise en place de ces filets sur le cylindre de marge, on a déjà proposé de disposer sur la face du filet adjacente au rebord en saillie, un ruban adhésif double face dont la face externe est initialement protégée par un ruban de protection (brevet FR 80 06862).In order to facilitate the positioning of these threads on the margin cylinder, it has already been proposed to have on the face of the thread adjacent to the projecting rim, a double-sided adhesive tape whose external face is initially protected by a ribbon of protection (patent FR 80 06862).
Grâce à cette disposition, la mise en place des filets perforants sur le cylindre de marge peut s'obtenir en effectuant les opérations suivantes :
- l'impression sur une feuille de papier d'une maquette de l'épreuve que l'on souhaite réaliser,
- la fixation temporaire, sur cette maquette, des filets perforants, de telle sorte que les rebords se trouvent aux emplacements où se situent les perforations ou les découpes que l'on désire réaliser, cette fixation temporaire étant réalisée en appliquant le filet perforant sur la maquette par sa face adjacente au rebord après avoir ôté la bande de protection qui recouvrait initialement l'adhésif double face,
- le passage de la maquette ainsi réalisée dans la machine d'impression, après extraction de la bande de protection de la couche adhésive des différents filets de manière à ce qu'en cours de ce passage, les filets viennent se coller sur le cylindre de marge aux emplacements qu'ils doivent occuper et qu'en même temps l'adhésif double face soit extrait en même temps que la feuille sur laquelle il se trouve collé, en raison du fait que l'adhérence adhésif/métal des filets est plus faible que l'adhérence adhésif/papier.
- the printing on a sheet of paper of a model of the test that one wishes to carry out,
- the temporary fixing, on this model, of the perforating nets, so that the flanges are at the locations where the perforations or the cuts which one wishes to make are located, this temporary fixing being carried out by applying the perforating net on the model by its face adjacent to the edge after removing the protective strip which initially covered the double-sided adhesive,
- the passage of the mock-up thus produced in the printing machine, after extraction of the protective tape from the adhesive layer of the different threads so that, during this passage, the threads stick to the margin cylinder at the locations they must occupy and at the same time the double-sided adhesive is removed at the same time as the sheet on which it is stuck, due to the fact that the adhesive / metal adhesion of the threads is weaker than adhesive / paper adhesion.
En raison de la facilité de sa mise en oeuvre, ce procédé a largement contribué à généraliser l'emploi de filets perforants dans les machines d'impression Offset.Because of the ease of its implementation, this process has largely contributed to the widespread use of perforating nets in offset printing machines.
Toutefois, cette généralisation a fait apparaître un problème inhérent à cette technique qui tient au fait qu'à la longue les blanchets se trouvent prématurément usés voire même détériorés par l'action des filets perforants ou coupeurs.However, this generalization has revealed a problem inherent in this technique which is due to the fact that in the long term the blankets are prematurely worn or even deteriorated by the action of perforating or cutting nets.
En conséquence, ces blanchets doivent être fréquemment changés, ce qui pénalise cette technique notamment du fait :
- du coût relativement élevé des blanchets,
- du prix des interventions nécessaires pour le remplacement de ces blanchets,
- des immobilisations de l'Offset pendant ces interventions.
- the relatively high cost of blankets,
- the price of the interventions necessary for the replacement of these blankets,
- Offset fixed assets during these interventions.
L'invention a donc plus particulièrement pour objet de supprimer ces inconvénients.The invention therefore more particularly aims to eliminate these drawbacks.
A cet effet, elle propose de disposer sur le blanchet, aux emplacements où viennent porter les filets perforants, des bandes de contre-appui consistant en une bande d'acier présentant une épaisseur de quelques dixièmes de millimètre, ces bandes étant fixées temporairement à la surface du blanchet, grâce à un revêtement adhésif déposé sur l'une de leurs faces.To this end, it proposes to have on the blanket, at the locations where the perforating nets come to carry, counter-support strips consisting of a steel strip having a thickness of a few tenths of a millimeter, these strips being temporarily fixed to the blanket surface, thanks to an adhesive coating deposited on one of their faces.
L'autre face des bandes de contre-appui pourra être revêtue d'un adhésif double face de manière à pouvoir assurer une mise en place selon une séquence comprenant les étapes suivantes :
- la réalisation d'une maquette à l'aide d'une feuille sur le recto de laquelle les lignes de perforation et/ou de (pré)découpes sont indiquées,
- la fixation temporaire sur le recto de cette maquette, grâce à l'adhésif double face, des bandes de contre-appui, celles-ci étant disposées de manière à suivre et à recouvrir les lignes de perforation et/ou de (pré)découpes,
- le passage dans la machine d'impression de la maquette ainsi réalisée, après avoir ôté si elle existe la bande de protection de la couche adhésive, de manière à ce qu'au cours de ce passage, les bandes de contre-appui viennent se coller sur le blanchet aux emplacements qu'elles doivent occuper, et que le ruban adhésif double face soit extrait en même temps que la feuille où il demeure collé, en raison de la différence de son pouvoir adhésif avec le papier de la maquette et le matériau constitutif des bandes de contre-appui.
- the production of a model using a sheet on the front of which the perforation lines and / or (pre) cuts are indicated,
- the temporary fixing on the front of this model, using the double-sided adhesive, of the counter-support strips, these being arranged so as to follow and cover the lines of perforation and / or (pre) cuts,
- the passage in the printing machine of the mock-up thus produced, after having removed if there is the protective strip from the adhesive layer, so that during this passage, the counter-support strips come to stick on the blanket in the places they must occupy, and that the double-sided adhesive tape is removed at the same time as the sheet where it remains stuck, due to the difference of its adhesive power with the paper of the model and the material of the backing strips.
Avantageusement, la feuille utilisée pour réaliser la maquette est préalablement passée dans la machine d'impression équipée des filets perforants et/ou des filets coupeurs de sorte que les lignes de perforation et/ou de coupes sont visibles en relief sur le recto de la feuille.Advantageously, the sheet used to make the model is previously passed through the printing machine equipped with perforating nets and / or cutting nets so that the perforation and / or cutting lines are visible in relief on the front of the sheet. .

- Figure 1 schematically shows an offset type printing machine;
- Figure 2 is a schematic perspective of a strip of abutment according to the invention;
- Figure 3 is a cross section of the strip shown in Figure 1;

Comme précédemment mentionné, l'invention s'adresse aux machines de type Offset ou similaire comprenant, de la façon indiquée sur la figure 1 un cylindre porte-plaque 1 muni de rouleaux encreurs 2 et de rouleaux de mouillage 3, un blanchet 4 et un cylindre de contre pression appelé habituellement cylindre de marge 5.As previously mentioned, the invention is intended for machines of the offset or similar type comprising, as shown in FIG. 1, a plate cylinder 1 provided with ink rollers 2 and wetting rollers 3, a
Dans une machine de ce genre, les feuilles vierges à imprimer qui sont initialement empilées dans un poste d'alimentation 6, sont transmises une à une dans une aire de margeage 7 avant de passer entre le blanchet 4 et le cylindre de marge 5, lieu où s'effectue l'impression.In a machine of this kind, the blank sheets to be printed which are initially stacked in a feeding station 6, are transmitted one by one in a margining area 7 before passing between the
Les feuilles 8 ainsi imprimées viennent ensuite s'empiler dans un poste de réception 9.The
La mise en place de filets perforants (ou de filets coupeurs) sur le cylindre de marge 5 peut s'effectuer comme illustré sur les figures 4 et 5 grâce à des filets perforants 10 dont le côté inférieur (opposé au côté coupant ou perforant) est enduit d'une couche adhésive 11, tandis que le côté supérieur est recouvert d'une bande adhésive double face 12.The installation of perforating nets (or cutting nets) on the
En vue d'effectuer cette mise en place, l'opérateur procède tout d'abord à l'impression d'une feuille 8. Grâce à l'adhésif double face 12, il colle les filets perforants au verso de la feuille 8 où doivent s'effectuer les perforations, les éléments coupants ou perforant étant orientés vers la feuille 8 (figure 4).In order to carry out this positioning, the operator first of all prints a
Il passe ensuite la maquette ainsi réalisée dans la machine, les filets perforants 10 étant placés du côté du cylindre de marge 5.It then passes the model thus produced in the machine, the
Au cours de leur passage entre le blanchet 4 et le cylindre de marge 5, les filets perforants 10 viennent automatiquement se coller sur le cylindre de marge 5. Simultanément, la bande adhésive double face 12 qui reste collée sur la feuille 8, se détache des filets perforants 10 (figure 5).During their passage between the
Au terme du passage de la feuille 8, les filets perforants 10 se trouvent placés sur le cylindre de marge 5 aux emplacements convenables. L'opérateur peut donc effectuer ses opérations d'impression avec perforation ou découpe.At the end of the passage of the
Comme précédemment mentionné, l' inconvénient de ce mode de perforation ou de découpe consiste en ce qu'il provoque une usure prématurée (ou même des détériorations) du blanchet 5.As previously mentioned, the disadvantage of this mode of perforation or cutting consists in that it causes premature wear (or even deterioration) of the
L'invention propose donc de placer sur le blanchet 4 des bandes de contre-appui 13 aux emplacements sur lesquelles viennent porter les éléments coupants ou perforants des filets 10.The invention therefore proposes placing
Dans le but de faciliter la mise en place des bandes de contre-appui 12 sur le blanchet 4, ces bandes 13 pourront être initialement recouvertes :
- d'un côté, par une couche en matériau adhésif 14 recouverte d'une bande de
protection 15 que l'on peut ôter lors de l'utilisation, - de l'autre côté, par une bande adhésive double face 16 (c'est-à-dire une bande souple portant sur ses deux faces un revêtement adhésif 17, 18), le revêtement adhésif 17 opposé à la
bande 13 étant initialement protégé par une bande deprotection 19 que l'on peut ôter lors de l'utilisation.
- on the one hand, by a layer of
adhesive material 14 covered with aprotective strip 15 which can be removed during use, - on the other side, by a double-sided adhesive strip 16 (that is to say a flexible strip carrying on its two faces an
adhesive coating 17, 18), theadhesive coating 17 opposite to thestrip 13 being initially protected by aprotective strip 19 which can be removed during use.
La mise en place des bandes de contre-appui 13 précédemment décrites peut être avantageusement effectuée comme suit :The establishment of the
Une fois les filets perforants 10 disposés sur le cylindre de marge 5, par exemple de la façon illustrée sur les figues 4 et 5, l'opérateur passe une feuille 8' dans la machine de manière à obtenir une épreuve munie des lignes de découpes et/ou de perforations 20, lesquelles sont visibles au recto de la feuille 8' (ici, en traits interrompus).Once the
Après avoir ôté les rubans de protection 15, l'opérateur fixe les bandes de contre-appui 13 sur l'épreuve 8' en faisant en sorte que leur axe longitudinal de symétrie se trouve sensiblement en coïncidence avec les lignes de découpe et/ou de perforation 20, la fixation de ces bandes 13 sur l'épreuve 8' étant alors obtenue grâce à l'adhésif double face 16.After having removed the
Une fois cette opération terminée, l'opérateur passe à la machine l'épreuve 8' munie des bandes de contre-appui 13, celles-ci étant orientées du côté du blanchet 4.Once this operation has been completed, the operator passes the
Au cours de leur passage entre le blanchet 4 et le cylindre de marge 5, les bandes de contre-appui 13 viennent automatiquement se coller sur le blanchet 4.During their passage between the
Parallélement, la bande adhésive double face 16 qui reste collée sur la feuille 8', se détache des bandes 13 (l'adhérence de l'adhésif double face étant plus forte sur le papier que sur la bande 13).At the same time, the double-sided
Au terme du passage de l'épreuve, les bandes de contre-appui 13 se trouvent placées sur le blanchet 4 aux emplacements appropriés, vis-à-vis des filets de découpes et/ou des filets perforants 10.At the end of the test, the counter-support strips 13 are placed on the
L'opérateur peut alors effectuer ses opérations d'impression avec perforation et découpe.The operator can then perform his printing operations with perforation and cutting.
Il convient de noter qu'il faut tenir compte de l'épaisseur des filets perforants 10 et des bandes de contre-appui 13, le procédé précédemment décrit pourra en outre comprendre au moins une phase de réglage de pression entre le blanchet 4 et le cylindre de marge 5. Ce réglage pourra être avantageusement effectué en fin de pose des filets perforants 10 et/ou en fin de pose des bandes de contre-appui 13.It should be noted that the thickness of the perforating
Avantageusement, les bandes de contre-appui 13 pourront consister en une bande d'acier d'épaisseur de quelques dixièmes de millimètres (par exemple 0,2 mm) et de largeur de quelques millimètres (par exemple 4 mm).Advantageously, the counter-support strips 13 may consist of a steel strip with a thickness of a few tenths of a millimeter (for example 0.2 mm) and a width of a few millimeters (for example 4 mm).
Les avantages du procédé précédemment décrit apparaissent clairement.The advantages of the method described above are clearly apparent.
Il peut s'utiliser sur toutes les machines d'impression de type Offset, même celles qui ne permettent pas un accès suffisant au blanchet et au cylindre de marge.It can be used on all offset printing machines, even those that do not allow sufficient access to the blanket and the margin cylinder.
Il supprime toute intervention directe de l'opérateur sur ces cylindres et les inconvénients qui en découlent.It eliminates any direct operator intervention on these cylinders and the resulting drawbacks.
Les opérations de mise en place des bandes de contre-appui sont faciles à exécuter : de même que pour les filets perforants, la pose des bandes de contre-appui sur la maquette peut s'effectuer à plat sur une table de travail.The operations for placing the counter-support strips are easy to carry out: as with the perforating nets, the installation of the counter-support strips on the model can be carried out flat on a work table.
Bien entendu, l'usage des bandes de contre-appui assure une protection des blanchets, et donc un allongement de la durée de vie de ces derniers.Of course, the use of the counter-support strips ensures protection of the blankets, and therefore an extension of the life of the latter.
