patrones. Además, se deberá entender que los patrones G1 a G5 podrían ser todos diferentes con respecto a los patrones G6 a G11. patterns. In addition, it should be understood that patterns G1 to G5 could all be different with respect to patterns G6 to G11.

Asimismo, en el ejemplo que se ilustra, en el rodillo 5 los patrones G1 a G5 de la banda izquierda BC son iguales (incluso aunque estén dispuestos de una manera diferente) con respecto a los patrones de la banda derecha BC. Lo mismo sucede con los patrones G6 a G11 del rodillo 11. Sin embargo, también en este caso se entiende que las diversas bandas centrales BC, en las que se subdivide cada rodillo de gofrado 5, 11, podrían caracterizarse por un patrón diferente de banda a banda, en cuyo caso se obtiene una mayor variabilidad de los patrones finales de los rollos. De este modo, se podrían obtener por ejemplo paquetes de rollos R en los que cada rollo presente una gran cantidad (M1xM2) de combinaciones de motivos diferentes, con todos los rollos diferentes entre sí, obtenidos a partir de capas V1, V2 gofradas en relieve en correspondencia de bandas BC en las que se obtienen diferentes patrones de gofrado. Also, in the example illustrated, in roller 5 the patterns G1 to G5 of the left band BC are the same (even if they are arranged differently) with respect to the patterns of the right band BC. The same applies to patterns G6 to G11 of roller 11. However, it is also understood in this case that the various central bands BC, into which each embossing roller 5, 11 is subdivided, could be characterized by a different band pattern a band, in which case a greater variability of the final patterns of the rolls is obtained. Thus, for example, packages of R rolls could be obtained in which each roll has a large amount (M1xM2) of combinations of different patterns, with all rolls different from each other, obtained from embossed layers V1, V2 in correspondence of BC bands in which different embossing patterns are obtained.

Por lo menos algunas de las ventajas que se pueden obtener con la unidad de gofrado y el procedimiento de gofrado descritos anteriormente se pueden utilizar también en productos que no estén subdivididos en hojas, es decir, productos continuos o sin líneas de perforación transversales T. De hecho, en este caso también se puede obtener una variación elevada de los motivos superficiales del producto. Sin embargo, en este caso se podrá definir una longitud de base L (que no estará necesariamente relacionada con una dimensión de hoja), que defina los paneles R y sobre cuya base determine la extensión circunferencial de los rodillos de gofrado (como múltiplo de dicha longitud de base). At least some of the advantages that can be obtained with the embossing unit and the embossing process described above can also be used in products that are not subdivided into sheets, that is, continuous products or without transverse perforation lines T. In fact, in this case a high variation of the surface motifs of the product can also be obtained. However, in this case a base length L may be defined (which will not necessarily be related to a sheet dimension), which defines the R panels and on whose base determines the circumferential extent of the embossing rollers (as a multiple of said base length).

De forma alternativa, también en el caso de productos subdivididos en hojas mediante líneas de perforación, se puede variar la apariencia de las diversas hojas sin un acompasado entre el objeto decorado y la línea de perforación, mediante el uso de un rodillo con patrones continuos o discontinuos, que se puede interponer entre patrones continuos o discontinuos en el otro rodillo. Alternatively, also in the case of products subdivided into sheets by means of perforation lines, the appearance of the various sheets can be varied without a rhythm between the decorated object and the perforation line, by using a roller with continuous patterns or discontinuous, which can be interposed between continuous or discontinuous patterns in the other roller.

En la descripción anterior, se ha hecho referencia a una unidad de gofrado y laminado que produce un material en banda N con dos capas unidas entre sí mediante encolado. Sin embargo, las enseñanzas proporcionadas por la presente invención se pueden aplicar también a unidades de gofrado más complejas, con más de dos recorridos para más de dos capas, así como a unidades de gofrado más sencillas, aunque en este caso de forma menos ventajosa. In the above description, reference has been made to an embossing and rolling unit that produces an N-band material with two layers joined together by gluing. However, the teachings provided by the present invention can also be applied to more complex embossing units, with more than two paths for more than two layers, as well as simpler embossing units, although in this case less advantageously.

Las figuras 8 y 9 muestran una forma de realización, en la que la unidad de gofrado está concebida para producir un material en banda en una sola capa, o incluso constituida por más capas, pero gofrada conjuntamente. En una forma de realización, la unidad de gofrado, indicada en su totalidad con la referencia 100, comprende un primer rodillo de presión 103, que puede presentar una superficie cilíndrica revestida en una capa flexible elásticamente 103A, tal como caucho o similar. El rodillo de presión 103 forma, con un primer rodillo de gofrado 105, una línea de contacto de gofrado 104, por la que se desplaza el material en banda N para su gofrado. El primer rodillo de gofrado prevé una pluralidad de protuberancias 105P (véase la ampliación en la figura 8A), que definen un primer patrón de gofrado. A lo largo del recorrido del material en banda N se dispone un segundo rodillo de presión 107 que coopera con un segundo rodillo de gofrado 109 provisto de protuberancias de gofrado 109P (figura 8B). En una forma de realización, las superficies cilíndricas de los rodillos de gofrado 105 y 109 se pueden configurar tal como se muestra en las figuras 3 y 4, presentando así dos diámetros diferentes entre sí. En una forma de realización, el rodillo 109 presenta un diámetro mayor que el diámetro del rodillo 105 y su circunferencia es igual a un múltiplo M1 (por ejemplo M1=5) de una longitud de base L representada por la longitud de las hojas en las que se subdivide el material en banda N mediante líneas de perforación en una fase de procesado posterior, por ejemplo por una unidad de perforación 21 (figura 7). El rodillo de gofrado 109 presenta una longitud de circunferencia igual a LxM2, donde M2 es diferente de M1, por ejemplo M2=6. Figures 8 and 9 show an embodiment, in which the embossing unit is designed to produce a web material in a single layer, or even constituted by more layers, but embossed together. In one embodiment, the embossing unit, indicated in its entirety with reference 100, comprises a first pressure roller 103, which can have a cylindrical surface coated in an elastically flexible layer 103A, such as rubber or the like. The pressure roller 103 forms, with a first embossing roller 105, an embossing contact line 104, through which the N-band material travels for embossing. The first embossing roller provides a plurality of protrusions 105P (see enlargement in Figure 8A), which define a first embossing pattern. Along the path of the N-band material, a second pressure roller 107 is arranged which cooperates with a second embossing roller 109 provided with embossing protuberances 109P (Figure 8B). In one embodiment, the cylindrical surfaces of the embossing rollers 105 and 109 can be configured as shown in Figures 3 and 4, thus presenting two different diameters. In one embodiment, the roller 109 has a diameter greater than the diameter of the roller 105 and its circumference is equal to a multiple M1 (for example M1 = 5) of a base length L represented by the length of the sheets in the that the N-band material is subdivided by drilling lines in a subsequent processing phase, for example by a drilling unit 21 (Figure 7). Embossing roller 109 has a circumference length equal to LxM2, where M2 is different from M1, for example M2 = 6.

Como el material en banda N se gofra dos veces en los dos rodillos 105 y 109, con el fin de evitar que durante el segundo gofrado se presione el patrón gofrado mediante el rodillo 105, los patrones de gofrado obtenidos por los dos rodillos 105 y 109 ventajosamente están desplazados, tal como se muestra para los motivos de gofrado G1 a G11 de las figuras 3 y 4. De esta manera, cada panel R, en el que está subdividido el segundo rodillo de gofrado 109, decorará una parte del material en banda que todavía no se ha gofrado mediante el panel R correspondiente del rodillo 105. Los rodillos 105 y 109 pueden estar lo suficientemente próximos como para evitar que el material en banda se deslice excesivamente, a fin de asegurar un correcto posicionamiento de los patrones de gofrado producidos por los dos rodillos en la misma zona del material N, es decir, sobre la parte de material N destinada a formar una misma hoja F. El rodillo de presión 107 que coopera con el segundo rodillo de gofrado 109 y que define con este último una segunda línea de contacto de gofrado 108 puede presentar un área hueca 107A, correspondiente a la posición en la que está situado en el material N el motivo gofrado mediante el rodillo de gofrado 105. Esto evita la compresión del patrón de gofrado formado por el primer par de rodillos 103, As the N-band material is embossed twice on the two rollers 105 and 109, in order to prevent the embossing pattern from being pressed by the roller 105 during the second embossing, the embossing patterns obtained by the two rollers 105 and 109 advantageously they are displaced, as shown for the embossing patterns G1 to G11 of Figures 3 and 4. Thus, each panel R, into which the second embossing roller 109 is subdivided, will decorate a part of the web material which has not yet been embossed by the corresponding panel R of the roller 105. The rollers 105 and 109 may be close enough to prevent the web material from slipping excessively, in order to ensure proper positioning of the embossing patterns produced by the two rollers in the same area of material N, that is, on the part of material N intended to form the same sheet F. The pressure roller 107 cooperating with the second embossing roller 109 and defining with the latter a second embossing contact line 108 may have a hollow area 107A, corresponding to the position in which the embossed pattern is placed in the material N by the embossing roller 105. This prevents compression of the embossing pattern formed by the first pair of rollers 103,

105. Ventajosamente, para evitar dificultades en el centrado del patrón de gofrado por los dos rodillos 105 y 109 en el mismo material en banda o capa N, se pueden omitir los patrones o las decoraciones continuos DC. 105. Advantageously, in order to avoid difficulties in centering the embossing pattern by the two rollers 105 and 109 in the same band or layer N material, DC patterns or continuous decorations can be omitted.

La Figura 9 muestra una sección esquemática muy ampliada de un material en banda N gofrado con la unidad de gofrado 100 de las figuras 8, 8A y 8B. Las referencias P105 y P109 indican las protuberancias de gofrado Figure 9 shows a highly enlarged schematic section of an embossed N-band material with the embossing unit 100 of Figures 8, 8A and 8B. References P105 and P109 indicate embossing bumps
