Description

La présente invention a pour objet un ruban composite pour machi­nes d'impression et une machine d'impression utilisant un tel ruban.The present invention relates to a composite ribbon for printing machines and a printing machine using such a ribbon.

On connaît déjà des machines d'impression des étiquettes par transfert thermique.
De telles machines sont susceptibles d'imprimer automatiquement en fonction de données introduites dans leurs mémoires, une gran­de série d'étiquettes.
Ces étiquettes sont par exemple destinées aux marquages de divers produits proposés à la vente et les marques qu'elles reçoivent peuvent être des codes barres.Machines for printing labels by thermal transfer are already known.
Depending on the data entered in their memories, such machines are capable of automatically printing a large series of labels.
These labels are for example intended for the markings of various products offered for sale and the marks which they receive may be bar codes.

Les machines d'impression par transfert thermique connues sont pourvues d'une tête d'impression chauffante sous laquelle est entrainé en continu le ruban d'étiquettes.
Ces machines sont également dotées d'un ruban encreur qui est entrainé en continu sous la tête d'impression, contre le ruban d'étiquettes la même vitesse que ce dernier.
La tête d'impression est pourvue d'une pluralité de points chauffés sélectivement pour former sur l'étiquette la marque cor­respondante.
Le transfert de l'encre du ruban encreur vers l'étiquette est effectuée dans ce cas par chauffage.Known thermal transfer printing machines are provided with a heated printing head under which the label tape is continuously driven.
These machines also have an ink ribbon which is continuously driven under the print head, against the label ribbon at the same speed as the latter.
The print head is provided with a plurality of dots selectively heated to form the corresponding mark on the label.
In this case, the ink is transferred from the ink ribbon to the label by heating.

Les machines à imprimer de l'art antérieur utilisent donc deux consommables à savoir le ruban encreur et le ruban d'étiquettes. Un des nombreux inconvénients résultant de l'utilisation de deux consommables, réside dans le fait que ces derniers ne sont pas toujours de la même longueur si bien que la machine d'impres­ sion peut, si l'opérateur n'y prend pas garde, poursuivre l'im­pression malgré le dévidage complet, soit du ruban encreur, soit du ruban d'étiquettes.The printing machines of the prior art therefore use two consumables, namely the ink ribbon and the label ribbon. One of the many drawbacks resulting from the use of two consumables, is that they are not always the same length so that the printing machine sion may, if the operator is not careful, continue printing despite the complete unwinding, either of the ink ribbon or of the label ribbon.

Un autre inconvénient réside dans le fait que l'opérateur devra effectuer deux interventions sur la machine, une pour charger le ruban encreur, l'autre pour charger un ruban d'étiquettes.Another disadvantage lies in the fact that the operator will have to carry out two operations on the machine, one to load the ink ribbon, the other to load a label ribbon.

Un autre inconvénient réside dans le fait que ces deux interven­tions ne pourront être effectuées simultanément, ceci essen­tiellement en raison de la différence de longueur des deux rubans.Another drawback lies in the fact that these two operations cannot be carried out simultaneously, this essentially due to the difference in length of the two ribbons.

Les machines à imprimer sont conçues de manière à pouvoir impri­mer des rubans de différentes largeurs.The printing machines are designed so that they can print ribbons of different widths.

L'utilisateur d'une telle machine pour répondre à la demande, de­vra donc posséder des rubans encreurs de largeurs adaptés à cel­les des rubans d'étiquettes et devra donc gérer un double stock.The user of such a machine to meet demand will therefore have ink ribbons of widths adapted to those of label ribbons and will therefore have to manage a double stock.

La présente invention a pour objet de pallier aux inconvénients ci-dessus énoncés en mettant en oeuvre un nouveau ruban composite pour l'impression des étiquettes et une nouvelle machine utili­sant un tel ruban.The object of the present invention is to overcome the above-mentioned drawbacks by using a new composite ribbon for printing labels and a new machine using such a ribbon.

Le ruban composite selon la présente invention se caractérise essentiellement en ce qu'il est constitué par une bande sur la­quelle sont ménagées des zones imprimables, régulièrement espa­cées et par un ruban encreur recouvrant les zones imprimables et fixé à ces dernières et/ou à la bande.The composite ribbon according to the present invention is essentially characterized in that it consists of a strip on which are formed printable areas, regularly spaced apart and by an ink ribbon covering the printable areas and fixed to the latter and / or to the strip. .

Selon une autre caractéristique de l'invention, les zones impri­mables sont constituées par la face supérieure d'étiquettes auto­collantes détachables, disposées à intervalle régulier suivant au moins une rangée sur la bande support.According to another characteristic of the invention, the printable areas consist of the upper face of detachable self-adhesive labels, arranged at regular intervals along at least one row on the support strip.

Selon une autre caractéristique de l'invention, le ruban encreur est fixé à la bande et/ou aux zones imprimables par effet électro statique, c'est à dire sous l'effet de force attractive générée par des charges de signes contraires présentes respectivement sur le ruban encreur et sur la bande et/ou sur les zones imprimables de cette dernière.
Cette disposition est particulièrement avantageuse puisqu'elle permet l'utilisation de ruban encreur dont la largeur peut être inférieure à celle de la bande support et adaptée à la largeur des zones à recouvrir.According to another characteristic of the invention, the ink ribbon is fixed to the strip and / or to the printable areas by electrostatic effect, that is to say under the effect of attractive force generated by charges of contrary signs present respectively on the ink ribbon and on the strip and / or on the printable areas of the latter.
This arrangement is particularly advantageous since it allows the use of an ink ribbon, the width of which may be less than that of the support strip and adapted to the width of the areas to be covered.

Suivant une variante de réalisation, le ruban est de même lar­geur que la bande et le dit ruban et la dite bande sont fixés l'un à l'autre par leurs bords respectifs.According to an alternative embodiment, the ribbon is the same width as the strip and the said ribbon and the said strip are fixed to each other by their respective edges.

La présente invention a également pour objet une machine d'im­pression utilisant un ruban conforme à l'invention.
La machine d'impression comprend notamment un magasin dans lequel est disposé un ruban agencé en rouleau, une tête d'impression chauffante, un dispositif moteur d'avance en continu, qui coopère par adhérence avec le ruban pour amener sous la tête d'impres­sion une nouvelle zone à imprimer.
La machine selon la présente invention se caractérise essentiel­lement en ce qu'en amont de la tête d'impression, elle comporte un poste de détection des zones imprimables du ruban composite, qui émet un signal de détection pour chaque zone détectée, à par­tir duquel est engendrée l'impression de la zone imprimable pla­cée sous la tête.The present invention also relates to a printing machine using a ribbon according to the invention.
The printing machine comprises in particular a magazine in which is disposed a ribbon arranged in a roll, a heated printing head, a continuous feed motor device, which cooperates by adhesion with the ribbon to bring it under the printing head. a new area to print.
The machine according to the present invention is essentially characterized in that upstream of the print head, it includes a station for detecting the printable areas of the composite ribbon, which emits a detection signal for each detected area, from which the printing of the printable area placed under the head is generated.

Selon une autre caractéristique, les moyens de détection de l'é­tiquette détectent la variation de luminosité du ruban.According to another characteristic, the label detection means detect the variation in brightness of the ribbon.

Selon une autre caractéristique, les moyens de détection de l'é­tiquette détectent la variation d'épaisseur du ruban composite.According to another characteristic, the label detection means detect the variation in thickness of the composite tape.

D'autres avantages et caractéristiques de l'invention apparaî­tront à la lecture de la description d'une forme préférée de réa­lisation donnée à titre d'exemple non limitatif en se reférant aux dessins annexés en lesquels :

  • - la figure 1 est une vue en perspective en écorché d'un ruban composite selon l'invention,
  • - la figure 2 est une vue en coupe schématique d'une machine d'impression des étiquettes conformes à l'invention,

  • - la figure 4 est une vue en coupe selon la ligne AA de la fig 3,
  • - la figure 5 est une vue en coupe d'une troisième forme de réa­lisation des moyens de détection de l'étiquette.
Other advantages and characteristics of the invention will appear on reading the description of a preferred embodiment given by way of non-limiting example with reference to the accompanying drawings in which:
  • FIG. 1 is a cutaway perspective view of a composite tape according to the invention,
  • FIG. 2 is a schematic sectional view of a label printing machine according to the invention,
  • FIG. 3 is a sectional view of a second embodiment of the label detection means,
  • FIG. 4 is a sectional view along the line AA in FIG. 3,
  • - Figure 5 is a sectional view of a third embodiment of the label detection means.

Tel que représenté, le ruban 1 selon l'invention comprend une bande 2 sur laquelle sont ménagées des zones imprimables réguliè­rement espacées et par un ruban encreur 4 de largeur égale ou inférieure à celle de la bande recovrant au moins les zones im­primables et fixé à ces dernières et/ou à la bande 2.As shown, the ribbon 1 according to the invention comprises a band 2 on which are regularly spaced printable zones and by an ink ribbon 4 of width equal to or less than that of the band covering at least the printable zones and fixed to these last and / or to band 2.

Selon une première forme de réalisation, le ruban encreur 4 est fixé à la bande et/ou aux zones imprimables par effet électro­statique, c'est à dire sous l'effet de la force attractive eng­endrée par les charges de signes contraires présentes respective­ment sur le ruban encreur 4 et sur la bande 2 et/ou sur les zones imprimables de cette dernière.
Selon cette forme de réalisation, le ruban peut être de largeur inférieure à celle de la bande, et adaptée à la largeur des zones imprimables.
Toujours selon cette forme de réalisation, le ruban encreur est constitué par un film polyester d'épaisseur comprise entre 3,5 et 10 micron mètre revêtu d'une couche d'encre.
Il est bien évident que le ruban encreur 4 pourra être fixé de toute autre manière à la bande 2.According to a first embodiment, the ink ribbon 4 is fixed to the strip and / or to the printable areas by electrostatic effect, that is to say under the effect of the attractive force generated by the charges of contrary signs present respectively on the ink ribbon 4 and on the strip 2 and / or on the printable areas of the latter.
According to this embodiment, the ribbon can be of width less than that of the strip, and adapted to the width of the printable areas.
Still according to this embodiment, the ink ribbon consists of a polyester film with a thickness of between 3.5 and 10 micron meters coated with a layer of ink.
It is obvious that the ink ribbon 4 can be fixed in any other way to the strip 2.

C'est ainsi que le ruban encreur 4 et la bande 2 seront de même largeur et seront fixés l'un à l'autre parleurs bords respectifs. Selon une première forme de réalisation, le ruban encreur 4 sera fixé par gaufrage à la bande 2.Thus the ink ribbon 4 and the strip 2 will be of the same width and will be fixed to each other on their respective edges. According to a first embodiment, the ink ribbon 4 will be fixed by embossing to the strip 2.

Selon une deuxième forme de réalisation, la fixation du ruban 4 à la bande 2 sera effectuée par collage.According to a second embodiment, the fixing of the strip 4 to the strip 2 will be carried out by gluing.

Selon une troisième forme de réalisation, la fixation sera réali­sée par soudure à ultra-son.According to a third embodiment, the fixing will be carried out by ultrasonic welding.

Selon une forme préférentielle de réalisation, les zones impri­mables sont constituées par la face supérieure d'étiquettes détachables auto-collantes apposées sur la bande à intervalle régulier suivant une ou plusieurs rangées à écartement les unes des autres et des bords de la dite bande.
Selon cette forme de réalisation, la bande 2 joue le rôle d'un support.
Cette bande 2 pourra être constituée par un papier siliconé de façon à faciliter l'enlèvement des étiquettes et les étiquettes seront constituées en papier et seront pourvues d'une couche de matière adhésive pour être maintenues sur la couche de papier siliconé et pour pouvoir adhérer sur le support sur lequel elles seront ultérieurement apposées.
Selon une autre forme de réalisation, les zones imprimables seront ménagées directement sur la bande 2.
Cette dernière pourra comporter des lignes d'affaiblissement, transversales afin de pouvoir être divisée en étiquettes.According to a preferred embodiment, the printable zones consist of the upper face of detachable self-adhesive labels affixed to the strip at regular intervals in one or more rows spaced from one another and from the edges of said strip.
According to this embodiment, the strip 2 plays the role of a support.
This strip 2 may be formed by a silicone paper so as to facilitate the removal of the labels and the labels will be made of paper and will be provided with a layer of adhesive material to be maintained on the layer of silicone paper and to be able to adhere to the support on which they will be later affixed.
According to another embodiment, the printable areas will be provided directly on the strip 2.
The latter may include transverse weakening lines so that it can be divided into labels.

La machine selon l'invention utilisant un ruban composite tel que précédemment défini est par exemple une machine automatique d'impression des étiquettes par transfert thermique.The machine according to the invention using a composite ribbon as defined above is for example an automatic label printing machine by thermal transfer.

Une telle machine comprend notamment un magasin dans lequel est disposé un ruban 1 agencé en rouleau, une tête d'impression 5 chauffante, sous laquelle est entrainé le ruban composite. Ce ruban composite est en contact par la face supérieure du ruban encreur 4 avec la tête d'impression.
Cette tête est pourvue d'une pluralité de points sélectivement chauffés de façon à former, par transfert thermique de l'encre du ruban 4, le marquage désiré sur la zone imprimable du ruban com­posite 1.Such a machine comprises in particular a magazine in which is disposed a ribbon 1 arranged in a roll, a heated printing head 5, under which the composite ribbon is driven. This composite ribbon is in contact by the upper face of the ink ribbon 4 with the print head.
This head is provided with a plurality of points selectively heated so as to form, by thermal transfer of the ink of the ribbon 4, the desired marking on the printable area of the composite ribbon 1.

La machine comporte également un dispositif moteur 7 d'entraine­ment qui coopère par friction avec le ruban 1 pour entrainer en continu ce dernier sous la tête d'impression.The machine also includes a motor drive device 7 which cooperates by friction with the ribbon 1 to continuously drive the latter under the print head.

En aval de la tête d'impression et du dispositif d'entrainement en considérant le sens d'avancement du ruban dans la machine, le ruban encreur 4 est séparé de la bande 2 et est enroulé sur un moyeu 8 entrainé par un organe moteur.Downstream of the print head and the drive device, considering the direction of advancement of the ribbon in the machine, the ink ribbon 4 is separated from the band 2 and is wound on a hub 8 driven by a drive member.

La bande support 2 est enroulée sur un moyeu entrainé en rotation par tout moyen adapté ou est dirigée vers un massicot pour sépa­rer les étiquettes.The support strip 2 is wound on a hub driven in rotation by any suitable means or is directed towards a cutter to separate the labels.

Le dispositif moteur 7 est constitué par un galet 9 mobile en rotation sous la tête d'impression, venant en pression contre le ruban composite de façon à l'entrainer sous la dite tête d'imprssion.
Le ruban composite est enserré entre le galet 9 et la tête. Le coefficient d'adhérence du ruban composite contre la tête est inférieur à celui du galet 9 contre le dit ruban.
Le galet 9 est en prise avec un organe moteur 10 qui pourra être un moteur électrique pas à pas.The motor device 7 is constituted by a roller 9 movable in rotation under the print head, coming into pressure against the composite ribbon so as to drive it under said print head.
The composite ribbon is clamped between the roller 9 and the head. The coefficient of adhesion of the composite tape against the head is lower than that of the roller 9 against said tape.
The roller 9 is engaged with a motor member 10 which may be a stepping electric motor.

Conformément à l'invention, la machine en amont de la tête d'impression sur le trajet du ruban composite, à distance prédé­terminée ajustable de ce poste d'impression, est dotée d'un moyen 11 de détection des étiquettes.
Lorsque une étiquette est détectée, le moyen 11 émet un signal à destination des organes de commande de la machine.
Ceux-ci au terme d'un délai déterminé par un moyen de tempori­sation ajustable ou non, commande l'impression de la zone impri­mable placée sous la tête d'impression.According to the invention, the machine upstream of the print head on the path of the composite ribbon, at a predetermined adjustable distance from this printing station, is provided with a means 11 for detecting labels.
When a label is detected, the means 11 emits a signal intended for the control members of the machine.
These at the end of a period of time determined by means of an adjustable time delay or not, controls the printing of the printable area placed under the print head.

Le moyen 11 pourra être constitué par un organe de détection qui émet un signal électrique lorsqu' il détecte l'arrivée d'une zone imprimable et par un circuit électronique 11A qui remet en forme le signal électrique émis par l'organe de détection en sor­ te de ne délivrer aux organes de commande de la machine que des impulsions calibrées.The means 11 could be constituted by a detection member which emits an electrical signal when it detects the arrival of a printable area and by an electronic circuit 11A which reshapes the electrical signal emitted by the sensing member when it leaves te to deliver to the machine control elements only calibrated pulses.

De préférence, le moyen de détection des zones imprimables du ruban est monté en fixation sur un bâti 12 qui est monté sur un rail de guidage 13 avec possibilité de déplacement le long de celui-ci et de blocage en position à l'aide de vis de blocage. Le rail de guidage est solidaire du châssis de la machine. Ce rail de guidage s'étend parallèlement au trajet du ruban com­posite 1 de façon à ce que le bâti 12 et le moyen 11 qu'il por­te puissent être déplacés le long d'une portion de ce trajet. Cette disposition permet de régler l'écart entre le moyen de détection 11 et la tête d'impression de la machine, cet écart pouvant être égal à la valeur du pas d'espacement des zones imprimables ou bien à un multiple de celui-ci.Preferably, the means for detecting the printable areas of the ribbon is fixedly mounted on a frame 12 which is mounted on a guide rail 13 with the possibility of displacement along the latter and of locking in position using screws. blocking. The guide rail is integral with the machine chassis. This guide rail extends parallel to the path of the composite tape 1 so that the frame 12 and the means 11 which it carries can be moved along a portion of this path. This arrangement makes it possible to adjust the difference between the detection means 11 and the printing head of the machine, this difference being able to be equal to the value of the spacing step of the printable areas or else to a multiple thereof.

Selon une forme préférée de réalisation, l'organe de détection détecte la variation de luminosité du ruban composite observable depuis la face antérieure de la bande 2, c'est à dire la face exempte de zones imprimables.
Pour un ruban composite dont les zones imprimables sont consti­tuées par la face supérieure d'étiquettes apposées en rang sur une bande 2 siliconée translucide, la variation de luminosité résulte de la translucidité de la bande support 2, de l'opacité du ruban encreur 4 et du recouvrement par ce dernier des inter­valles séparant les étiquettes.
En éclairant la face antérieure du ruban apparaissent des zones claires correspondant aux étiquettes et des zones sombres corres­pondant aux intervalles entre les étiquettes.
L'organe de détection pourra être avantageusement constitué par une cellule opto-électronique 14 qui génère un courant en fonc­tion de la quantité de lumière qu'elle reçoit.
Cette cellule pourra être associée à un organe 15 d'émission de rayons lumineux, tel une lampe, qui éclairera la face anté­rieure de la bande support 2 et sera positionnée de façon à rece­voir les rayons lumineux réfléchis par la dite face antérieure ou issus de cette derniere.According to a preferred embodiment, the detection member detects the variation in brightness of the composite tape observable from the front face of the strip 2, that is to say the face free of printable areas.
For a composite ribbon, the printable areas of which consist of the upper face of labels affixed in a row on a translucent silicone band 2, the variation in brightness results from the translucency of the support band 2, the opacity of the ink ribbon 4 and the overlap by the latter of the intervals separating the labels.
By illuminating the front side of the ribbon, light areas corresponding to the labels appear and dark areas corresponding to the intervals between the labels.
The detection device may advantageously be constituted by an opto-electronic cell 14 which generates a current as a function of the quantity of light which it receives.
This cell may be associated with a member 15 for emitting light rays, such as a lamp, which will illuminate the front face of the support strip 2 and will be positioned so as to receive the light rays reflected by or from this said front face. last.

Selon une variante, la lampe 15 éclaire le ruban composite depuis la face visible du ruban d'impression, et la cellule opto-élec­tronique détecte toujours la variation de luminosité visible sur la face antérieure de la bande 2.
Cette disposition est particulièrement adaptée à la détection d'orifices transversaux ménagés dans un ruban composite pour repérer le début de chaque zone imprimable.According to a variant, the lamp 15 illuminates the composite ribbon from the visible face of the printing ribbon, and the opto-electronic cell always detects the variation in brightness visible on the front face of the strip 2.
This arrangement is particularly suitable for the detection of transverse orifices formed in a composite ribbon to locate the start of each printable area.

Selon une autre forme de réalisation, l'organe de détection détecte la variation d'épaisseur du ruban composite, ce dernier dans ce cas comportant des étiquettes détachables.
A cet effet, cet organe pourra comprendre une roue 16 montée en rotation sur un axe 17.
Cette roue sera amenée en pression contre le ruban composite et sera disposée de façon à pouvoir tourner sur elle-même lorsque le ruban composite est entrainé.
De préférence, la roue viendra au contact du ruban encreur 4. L'axe de la roue sera transversal au sens du défilement du ruban composite.
Le diamètre de la roue sera adapté à la valeur de l'intervalle entre deux étiquettes consécutives, afin que son mouvement, lors­qu'elle pénètrera dans l'intervalle entre deux étiquettes, soit détectable.According to another embodiment, the detection member detects the variation in thickness of the composite tape, the latter in this case comprising detachable labels.
To this end, this member may include a wheel 16 rotatably mounted on an axis 17.
This wheel will be brought into pressure against the composite ribbon and will be arranged so as to be able to turn on itself when the composite ribbon is driven.
Preferably, the wheel will come into contact with the ink ribbon 4. The axis of the wheel will be transverse to the direction of travel of the composite ribbon.
The diameter of the wheel will be adapted to the value of the interval between two consecutive labels, so that its movement, when it enters the interval between two labels, is detectable.

De préférence, l'axe de la roue sera fixé au bâti 12 et recevra une jauge de contrainte 18 d'un type connu, par exemple du type de celle dont la résistance électrique varie en fonction de sa déformation qu'elles subissent.
Cette jauge fixée de toute manière connue à l'axe de la roue pourra être connectée électriquement à un pont de mesure tel un pont wheastone pour mesurer le courant représentatif de la défor­mation de l'axe de la roue.
Ce pont de mesure sera couplé électriquement à l'organe 11A afin que ce dernier puisse délivrer une impulsion représentative du passage de la roue d'un creux vers une bosse, significatif de la présence d'une étiquette.Preferably, the axis of the wheel will be fixed to the frame 12 and will receive a strain gauge 18 of a known type, for example of the type whose electrical resistance varies as a function of its deformation which they undergo.
This gauge fixed in any known manner to the axis of the wheel can be electrically connected to a measurement bridge such as a wheastone bridge to measure the current representative of the deformation of the axis of the wheel.
This measurement bridge will be electrically coupled to the member 11A so that the latter can deliver an impulse representative of the passage of the wheel from a hollow to a bump, indicative of the presence of a label.

A titre d'exemple, la roue pourra être montée en extrémité de l'axe et la longueur de ce dernier sera largement supérieure à la largeur de la roue de façon à pouvoir recevoir entre la dite roue et son autre extrémité qui sera encastrée dans le bâti 12, la jauge de contrainte.
Le paramètre détecté sera alors la flexion de l'axe de la roue provoquée par le passage sous cette dernière des creux et bosses du ruban composite correspondant respectivement aux intervalles entre les étiquettes et aux étiquettes.For example, the wheel can be mounted at the end of the axle and the length of the latter will be much greater than the width of the wheel so as to be able to receive between said wheel and its other end which will be embedded in the frame 12, the strain gauge.
The detected parameter will then be the bending of the wheel axis caused by the passage under the latter of the recesses and bumps in the composite tape corresponding respectively to the intervals between the labels and to the labels.

Selon une autre forme de réalisation, l'organe de détection est constitué par une roue 19 montée en rotation sur un axe 20 monté dans une chape 21 fixée à un dispositif 22 d'amplification du mouvement de montée et descente de la roue.According to another embodiment, the detection member consists of a wheel 19 rotatably mounted on an axis 20 mounted in a yoke 21 fixed to a device 22 for amplifying the movement of raising and lowering of the wheel.

La roue 19 sera orientée de façon à pouvoir tourner sur elle-­ même lors du défilement du ruban composite.The wheel 19 will be oriented so that it can turn on it- even when the composite ribbon runs.

Ce dispositif sera fixé au bâti 12 et pourra être un disposi­tif à levier.
Ce dispositif sera associé à des moyens électriques par exemple des capteurs 23 pour détecter les positions basse et haute d'un repère mécanique 24 solidaire du dispositif, ces positions basse et haute étant représentatives de la position de la roue, soit dans un creux du ruban 1, significatif d'un intervalle, soit sur une bosse du ruban 1 significative de la présence d'une étiquet­te.This device will be fixed to the frame 12 and may be a lever device.
This device will be associated with electrical means, for example sensors 23 for detecting the low and high positions of a mechanical mark 24 secured to the device, these low and high positions being representative of the position of the wheel, ie in a hollow in the ribbon. 1, significant of an interval, or on a bump in the ribbon 1 significant of the presence of a label.

Le ruban composite tel que décrit dont le ruban encreur est fixé à la bande 2 et aux zones imprimables par effet électro-statique présente un certain nombre d'avantages.
En effet, la liaison entre le ruban encreur et la bande 2 et les étiquettes s'effectue suivant toute l'étendue des faces en contact et ce sans utilisation de moyens de liaison annexes.
La séparation du ruban encreur après impression s'en trouvera faci­litée.
De plus, ce mode particulier de fixation autorise la réalisation de ruban encreur de largeur importante.The composite ribbon as described, the ink ribbon of which is fixed to the band 2 and to the areas that can be printed by electrostatic effect has a number of advantages.
In fact, the connection between the ink ribbon and the strip 2 and the labels takes place over the entire extent of the faces in contact, without using additional connecting means.
The separation of the ink ribbon after printing will be facilitated.
In addition, this particular method of fixing allows the production of a large width ink ribbon.

Il est à noter également que le mode particulier de fixation auto­rise la fabrication de ruban composite dont la largeur est limitée à la valeur nécessaire pour assurer le recouvrement total des éti­quettes imprimables sans peu de débordement latéral par rapport à ces dernières. Enfin, il faut noter que la fabrication de tels rubans n'aura nul besoin de faire appel aux techniques complexes et couteuses utili­sées actuellement pour inhiber l'électricité statique.It should also be noted that the particular method of attachment allows the production of composite tape, the width of which is limited to the value necessary to ensure total recovery of the printable labels without a little lateral overhang relative to the latter. Finally, it should be noted that the manufacture of such ribbons will not need to use the complex and expensive techniques currently used to inhibit static electricity.

De plus, grâce à ce ruban, il est possible d'utiliser la to­talité de la largeur d'impression de l'imprimante.In addition, thanks to this ribbon, it is possible to use the entire printing width of the printer.

Il va de soi que la présente invention peut recevoir tous aménagements et toutes variantes sans pour autant sortir du cadre du présent brevet.It goes without saying that the present invention can receive all arrangements and all variants without departing from the scope of this patent.
