Abstract

The imprinter has two rollers (10,12a) which can rotate about parallel axes (14). The two cylinders are synchronised and the strip of paper (11) can pass between the cylinders. Synchronisation takes place by lining up the holes (26,26a). Each of the cylinders has a longitudinal cut away portion (13,15) running the entire length of the cylinders. The surface (13) has equally spaced holes (20) to take the pins (21,22) and fix the plate (1) to the cylinder.

Description

L'invention est relative à un appareil d'î1npres;ion en relief par déformation du papier. The invention relates to an apparatus for printing in relief by deformation of the paper.

les appareils connus de ce genre comportent deux plaques rigides dont l'une (plaque-matrice) est entièrement métallique et présente, gravé en creux dans le métal, le motif à imprimer, l'autre Plaque (plaque-poinçon) présentant le motif complémentaire, en relief sur une matière moins dure, par exemple du carton. l'impression s'effec-tue en pressant le papier entre ces deux plaques de façon à lui conférer une déformation permanente correspondant audit motif. known devices of this kind have two rigid plates, one of which (matrix plate) is entirely metallic and has, etched into the metal, the pattern to be printed, the other plate (punch plate) having the complementary pattern , in relief on a less hard material, for example cardboard. printing is effected by pressing the paper between these two plates so as to give it a permanent deformation corresponding to said pattern.

Ces appareils, qui font appel au mouvement alternatif de deux plaques planes l'une vers l'autre, ont un fonctionnement lent et ne permettent donc pas l'édition de grands tirages à faible coQ.  These devices, which use the reciprocating movement of two flat plates towards each other, operate slowly and therefore do not allow the edition of large runs at low coQ.

L'invention permet au contraire de grands tirages. The invention, on the contrary, allows large runs.

Elle part de la constatation qu'il n'est pas indispensable que la plaque-matrice soit métallique. It starts from the observation that it is not essential that the matrix plate be metallic.

L'appareil selon l'invention est caractérisé en ce que la plaque-matrice et la plaque-poinçon sont, chacune, en une matière souple. The apparatus according to the invention is characterized in that the matrix plate and the punch plate are each made of a flexible material.

Dans le mode de réalisation préféré les plaques sont sur la surface de cylindres tournants respectifs entre lesquels passe le papier à imprimer. In the preferred embodiment the plates are on the surface of respective rotating cylinders between which the paper to be printed passes.

l'utilisation d'une plaque-matrice souple rend ainsi possible l'application à l'impression en relief par déformation du papier d'un apDareillage bien connu pour l'imprimerie à l'encre. the use of a flexible matrix plate thus makes it possible to apply to relief printing by deformation of the paper an apparatus well known for printing with ink.

On peut ainsi imprimer un motif en relief par déformation du papier à intervalles réguliers sur une bande se dévidant d'une bobine et nassant entre les deux cylindres. It is thus possible to print a relief pattern by deformation of the paper at regular intervals on a strip unwinding from a reel and becoming entangled between the two cylinders.

Dans une réalisation, les deux plaques souples sont fabriquées sar photogravure sur des plaques de photopolymères -telles que celles connues sous la laraue "DYCRIL" de la
Société BASF ou la n;araue "NYLOPRINT" de la Société DUPONT DE NE#OURS-qui, après exposition à la lut re, notamment ultraviolette, sont insolubles à certains liquides, en particulier l'alcool, les parties non exposées gardant cependant leur solubilité.Pour la fabrication de la pla--tue-matr.ce, on part d'une photoraphie en position du motif eb, pour la fabrication de la plaque-poinçon, on part de la mhme pètcgra- phie, mais en négatif. L'exposition à la lumière se fait par exemple par simple contact du positif et du négatif contre la plaque photosensible correspondante.In one embodiment, the two flexible plates are produced by photoengraving on photopolymer plates such as those known under the name "DYCRIL" of the
BASF Company or the "NYLOPRINT" company of the DUPONT DE NE # OURS Company - which, after exposure to wrestling, especially ultraviolet, are insoluble in certain liquids, in particular alcohol, the unexposed parts keeping their solubility.For the manufacture of the matte plate, we start from a photoraphy in position of the eb pattern, for the manufacture of the punch plate, we start from the same petrography, but in negative. The exposure to light is done for example by simple contact of the positive and the negative against the corresponding photosensitive plate.

D'autres caractéristiques de l'invention apparattront avec la description de l'un de ses modes de réalisation, celle-ci étant effectuée en se référant aux dessins ci-annexés, sur lesquels
- la figure I montre une plaque-matrice en cours de fa brication
- la figure 2 est une coupe d'une plaque-matrice

- la figure 4 est une vue-de face dtune plaque-matrice
- la figure 5 est une vue en perspective d'un appareil d'impression par déformation du papier ; et
- la figure 6 montre un mode de réglage de l'appareil de la figure 5.Other characteristics of the invention will appear with the description of one of its embodiments, this being carried out with reference to the attached drawings, in which
- Figure I shows a matrix plate being fabricated
- Figure 2 is a section of a matrix plate
- Figure 3 is a view similar to Figure 2 but for a punch plate
- Figure 4 is a front view of a matrix plate
- Figure 5 is a perspective view of a paper deformation printing apparatus; and
- Figure 6 shows an adjustment mode of the device of Figure 5.

Pour fabriquer une plaque-matrice d'un appareil d'impression en relief, on part d'une plaaue 1, figure 4, présentant un support 2 constitué d'une feuille métallique sur lequel est déposée une couche 3 de matière plastique photosensible, par exemple d'épaisseur 0,7 mm sur la couche 3, on applique un film photographique positif transparent 4 qu'on expose à de la lumière ultraviolette. To manufacture a matrix plate of a relief printing apparatus, one starts from a plate 1, FIG. 4, having a support 2 consisting of a metal sheet on which a layer 3 of photosensitive plastic is deposited, by example 0.7 mm thick on layer 3, a transparent positive photographic film 4 is applied which is exposed to ultraviolet light.

Après l'exposition, la plaque 1 est tremPée dans l'alcool et les zones de la couche 3 qui se trouvaient sous les parties noires du film 4, qui n'ont donc pas été exposées à la lumière ultraviolette, se dissolvent dans l'alcool et forment ainsi des creux 5 (figure 2). After the exposure, the plate 1 is soaked in alcohol and the areas of the layer 3 which were under the black parts of the film 4, which have therefore not been exposed to ultraviolet light, dissolve in the alcohol and thus form hollows 5 (Figure 2).

Pour réaliser une plaque-poinçon, on procède de manière analogue à ce qui a été décrit en relation avec la figure 1, le film positif 4 étant cependant remplacé par un film négatif transparent corresnondant, le résultat étant ainsi une plaque la avec des zones 6 en relief (figure 3). En outre, l'épaisseur, de l'ordre de 4/10 mm dans l'exemple, de la couche 3a de matière plastique photosensible de la plaque la est moins importante que celle de la couche 3. les creux ayant ainsi une profondeur de l'ordre de 7/10 mm et les reliefs 6 une hauteur de l'ordre de 4/10 mm, il est possible d'imprimer des papiers d'épaisseur importante. To make a punch plate, the procedure is analogous to that which has been described in relation to FIG. 1, the positive film 4 being however replaced by a corresponding transparent negative film, the result thus being a plate 1a with zones 6 in relief (Figure 3). In addition, the thickness, of the order of 4/10 mm in the example, of the layer 3a of photosensitive plastic material of the plate 1a is less important than that of layer 3, the hollows thus having a depth of of the order of 7/10 mm and the reliefs 6 a height of the order of 4/10 mm, it is possible to print papers of considerable thickness.

Au cours de l'exposition à la lumière, il est nécessaire que la plaque photosensible 1 et la pellicule photographique transparente aient des positions relatives bien déterminées. During exposure to light, it is necessary that the photosensitive plate 1 and the transparent photographic film have well determined relative positions.

C'est pourquoi la plaque 1 présente, au voisinage de l'un de ses bords 7 (figure 4) deux trous 8 et 9 ayant une position standard sur ladite plaque et les pellicules photographiques présentent des trous correspondants.This is why the plate 1 has, in the vicinity of one of its edges 7 (FIG. 4) two holes 8 and 9 having a standard position on said plate and the photographic films have corresponding holes.

Ces trous 8 et 9 servent également à disposer et positionner la plaque I sur un cylindre 10 faisant partie d'un appareil d'impression en relief d'une bande de papier Il se dévidant d'une bobine (non représentée). These holes 8 and 9 are also used to arrange and position the plate I on a cylinder 10 forming part of a device for printing in relief a strip of paper It unwinding from a reel (not shown).

La plaque la est, de la même manière, disposée sur la surface externe d'un cylindre 12 identiaue au cylindre 10 et d'axe parallèle à celui dudit cylindre 10, ces deux cylindres étant entraSnés en synchronisme. La bande de papier Il défile entre ces cylindres 10 et 12 et est serrée entre ceux-ci. The plate 1a is, in the same way, arranged on the external surface of a cylinder 12 identiaue to the cylinder 10 and of axis parallel to that of said cylinder 10, these two cylinders being driven in synchronism. The strip of paper It passes between these cylinders 10 and 12 and is clamped between them.

La surface 25 de chaque cylindre, par exemple celui de référence 10, présente sur toute sa longueur une encoche à faces 13 et 15 parallèles à l'axe 14 et perpendiculaires entre elles, la face 15 ayant la direction radiale. The surface 25 of each cylinder, for example that of reference 10, has over its entire length a notch with faces 13 and 15 parallel to the axis 14 and perpendicular to each other, the face 15 having the radial direction.

La face ou méplat 17 est percée à intervalles réguliers de trous 20. Pour fier la plaque 1 sur le cylindre 10, on dispose le bord 7 sur le méplat 13 parallèlement à l'arase 16 constituant le fond de l'encoche et de manière à faire coincider les trous 8 et 9 avec deux trous 20 dudit méplat, après quoi deux picots 21 et 22 sont enfoncés dans les trous 8 et 9 et 20 en correspondance et un adhésif double face ayant été préalablement disposé sur l & face de la plaque métallique 2 ne présentant pas la couche 7, ladite plaque 2 est collée sur la surface 25 du cylindre 10. Bien entendu, la distance entre les trous 8 et 9 est ur multiple de la distance entre deux trous 20 voisins. The face or flat 17 is pierced at regular intervals with holes 20. To secure the plate 1 on the cylinder 10, the edge 7 is placed on the flat 13 parallel to the level 16 constituting the bottom of the notch and so as to make the holes 8 and 9 coincide with two holes 20 of said flat, after which two pins 21 and 22 are pressed into the holes 8 and 9 and 20 in correspondence and a double-sided adhesive having been previously placed on the face of the metal plate 2 not having the layer 7, said plate 2 is bonded to the surface 25 of the cylinder 10. Of course, the distance between the holes 8 and 9 is a multiple of the distance between two neighboring holes 20.

la plaque la est disposée de la même manière sur le cylindre 12, en prenant garde, cependant, qu'elle ait la même position longitudinale que la plaque 1 sur le cylindre 10. the plate 1a is arranged in the same way on the cylinder 12, taking care, however, that it has the same longitudinal position as the plate 1 on the cylinder 10.

Pour que les cylindres 10 et 12 puissent être entraînés en rotation en phase, chacun de ces cylindres comporte une oreille 26, 26a en saillie de l'une de ses faces d'extrémité
27, 27a et au voisinage de sa surface exterre 25, 25a.So that the cylinders 10 and 12 can be driven in phase rotation, each of these cylinders has an ear 26, 26a projecting from one of its end faces
27, 27a and in the vicinity of its outer surface 25, 25a.

Pour effectuer cette mise en phase après qu'au moins un des cylindres ait été désolidarisé en rotation aie son arbre d'entrainement, on met l'oreille 26 du cylindre 10 en conco- dance avec l'oreille 26a du cylindre 12 (figure 63 cette concordance est maintenue en introduIsant une tige 7 dans les trous des deux oreilles et on recd de nouveau les cylir- dres solidaires des arbres d'entraînement correspondant,
Après ce calage, la tige 30 est enlevée.To carry out this phasing after at least one of the cylinders has been disconnected in rotation and has its drive shaft, the ear 26 of the cylinder 10 is brought into harmony with the ear 26a of the cylinder 12 (FIG. 63 this agreement is maintained by introducing a rod 7 into the holes of the two ears and the cylinders fixed to the corresponding drive shafts are again recd,
After this setting, the rod 30 is removed.

L'appareil permet l'impression à grande cadence; notaiz- ment d'une bande contInue de papier se dévidant d'une bobine ou de bandes continues pliées en accordéon comme des "listings". The device allows printing at high speed; notably a continuous strip of paper unwinding from a reel or continuous strips folded in accordion like "listings".

Il permet également l'impressioe de feuilles séparées.  It also allows printing of separate sheets.
