DESCRIPCIÓN DESCRIPTION
CAMPO TÉCNICO DE LA INVENCIÓN La presente invención se refiere a un procedimiento para la fabricación de un guarnecido interior de puerta para vehículo que comprende al menos un área decorativa recubierta con un revestimiento decorativo . TECHNICAL FIELD OF THE INVENTION The present invention relates to a process for the manufacture of an interior door trim for a vehicle comprising at least one decorative area covered with a decorative coating.
Adicionalmente, la invención se refiere a una instalación para la fabricación de dicho guarnecido interior de puerta para vehículo así como al guarnecido interior de puerta obtenido. Additionally, the invention relates to an installation for manufacturing said interior door trim for vehicle as well as to the interior door trim obtained.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Entre los guarnecidos interiores de puerta para vehículo son habituales los que comprenden un panel conformado de material plástico obtenidos por inyección o termoconformado . Among the interior trim of the door for vehicles, those comprising a panel formed of plastic material obtained by injection or thermoforming are common.
Con el objeto de mejorar el confort del usuario, especialmente en cuanto a las características de los materiales utilizados se refiere, es habitual que dichos guarnecidos interiores de puerta comprendan ciertas áreas recubiertas con revestimientos decorativos, bien porque presentan un tacto agradable o bien porque la calidad y/o aspecto de estos materiales son mejores que las de los utilizados en el resto del guarnecido interior de puerta. Estos revestimientos decorativos se fijan sobre ciertas áreas del guarnecido interior de puerta, como por ejemplo lo que se denomina medallón de puerta, situado entre la zona del reposabrazos de puerta y la parte superior de la misma o cintura. In order to improve user comfort, especially as regards the characteristics of the materials used, it is common for said interior door trim to include certain areas covered with decorative coverings, either because they have a pleasant touch or because the quality and / or appearance of these materials are better than those used in the rest of the interior door trim. These decorative coverings are fixed on certain areas of the interior door trim, such as what is called the door medallion, located between the area of the door armrest and the upper part of the door or waist.
Es muy importante que la fijación de dichos revestimientos decorativos sobre las áreas decorativas sea fiable y ofrezca un buen aspecto durable a lo largo de la vida útil del guarnecido interior de puerta. It is very important that the fixing of said decorative coverings on the decorative areas is reliable and offers a good durable appearance throughout the life of the interior door trim.
Con el objeto de asegurar la fiabilidad de la fijación, a la vez que se mantiene un buen aspecto entre el área decorativa y el revestimiento decorativo, normalmente se lleva a cabo la fabricación de dicha área decorativa recubierta con un revestimiento decorativo por separado, es decir, por un lado se fabrica el guarnecido interior de puerta con un orificio previsto para el posterior montaje del área decorativa recubierta con el revestimiento decorativo, y por otro lado se fabrica dicha área decorativa recubierta con un revestimiento decorativo. Finalmente se lleva a cabo la fijación de ambos elementos. In order to ensure the reliability of the fixation, while maintaining a good appearance between the decorative area and the decorative coating, the manufacturing of said decorative area coated with a separate decorative coating is usually carried out, that is to say On the one hand, the interior door trim is manufactured with a hole provided for the subsequent assembly of the decorative area covered with the decorative coating, and on the other hand said decorative area coated with a decorative coating is manufactured. Finally, the fixing of both elements is carried out.
Por un lado, el procedimiento más arriba descrito, presenta un número elevado de pasos que lo hacen complicado y caro. Por otro lado, el ajuste del área decorativa recubierta con el revestimiento decorativo en el orificio previsto en el guarnecido interior de puerta puede presentar problemas y alargar el tiempo de montaje, especialmente en los casos en los que el área decorativa presenta una geometría complicada . On the one hand, the procedure described above presents a high number of steps that make it complicated and expensive. On the other hand, the adjustment of the decorative area covered with the decorative coating in the hole provided in the interior door trim can present problems and lengthen the assembly time, especially in cases where the decorative area has a complicated geometry.
Por lo tanto, se considera más ventajoso un procedimiento en el que tanto el guarnecido interior de puerta como el área decorativa se formen como una sola pieza . De esta forma, el paso de recubrimiento se lleva a cabo en una etapa posterior una vez que se ha obtenido el guarnecido interior de puerta completo, donde el área decorativa forma parte integra de dicho guarnecido interior de puerta. Therefore, a procedure in which both the interior door trim and the decorative area are formed as a single piece. In this way, the coating step is carried out at a later stage once the complete interior door trim has been obtained, where the decorative area is an integral part of said interior door trim.
En este caso, el área decorativa del guarnecido interior de puerta se encuentra delimitada por un canal que la separa del resto del guarnecido interior de puerta . In this case, the decorative area of the interior door trim is delimited by a channel that separates it from the rest of the interior door trim.
Dicho canal, permite ocultar a los ojos del usuario la zona del contorno del revestimiento decorativo, donde se lleva a cabo el rematado del mismo. Normalmente el revestimiento decorativo se une al área decorativa mediante la utilización de adhesivo. Said channel allows to hide the contour area of the decorative covering, where the finishing of the same is carried out, from the user's eyes. Normally the decorative coating joins the decorative area through the use of adhesive.
Con el objeto de evitar el ensuciamiento del panel de puerta con adhesivo, el adhesivo se aplica directamente sobre el área decorativa, en lugar de aplicar dicho adhesivo sobre el revestimiento decorativo . In order to prevent fouling of the door panel with adhesive, the adhesive is applied directly on the decorative area, instead of applying said adhesive on the decorative coating.
El acceso de dicho adhesivo a la zona del canal que separa el área decorativa del resto del guarnecido interior de puerta es especialmente complicado. The access of said adhesive to the area of the channel that separates the decorative area from the rest of the interior door trim is especially complicated.
Por tanto, es difícil asegurar la continuidad del adhesivo a lo largo de dicho canal, lo que implica que haya zonas del revestimiento decorativo que no se pueden unir al área decorativa a lo largo de su contorno y que por tanto, debido a la ausencia de adhesivo en ciertas zonas, se acaban saliendo del canal ofreciendo un mal aspecto, y automáticamente el rechazo de las piezas . Therefore, it is difficult to ensure the continuity of the adhesive along said channel, which implies that there are areas of the decorative coating that cannot be attached to the decorative area along its contour and therefore, due to the absence of adhesive in certain areas, they end up leaving the channel offering a bad appearance, and automatically rejecting the pieces.
La patente EP0514541 muestra un procedimiento según las características descritas más arriba. EP0514541 shows a process according to the characteristics described above.
Por tanto, el objeto de la invención es un procedimiento para la fabricación de un guarnecido interior de puerta para vehículo que comprende un área decorativa recubierta con un revestimiento decorativo que sea simple y barato, a la vez que asegura un buen acabado estético durable a lo largo de la vida útil del guarnecido interior de puerta, y que además permita asegurar el ajuste del área decorativa recubierta con respecto al resto del guarnecido interior de puerta sin dificultad.

Si se retira dicho revestimiento decorativo (4), nos encontramos con una vista del guarnecido interior (1) de puerta representada en la figura 2. En dicha figura 2 se observa un canal (3) que establece una junta de separación entre el área decorativa (2) y el resto del guarnecido interior (1) de puerta y que comprende un conjunto de ranuras (3.3) situadas a lo largo del contorno del mismo. If said decorative covering (4) is removed, we find a view of the inner door trim (1) represented in figure 2. In said figure 2 a channel (3) is observed that establishes a separation joint between the decorative area (2) and the rest of the inner door trim (1) and comprising a set of grooves (3.3) located along the contour thereof.
Dicho canal (3) permite ocultar el contorno del revestimiento decorativo (4) en el interior del mismo. Said channel (3) makes it possible to hide the contour of the decorative covering (4) inside it.
Como se puede apreciar en el detalle A del canal (3) representado en la figura 4, dicho canal (3) comprende una primera pared (3.1) del canal (3) situada más próxima al área decorativa (2) y una segunda pared (3.2) del canal (3) situada más alejada del área decorativa ( 2 ) . As can be seen in detail A of the channel (3) represented in Figure 4, said channel (3) comprises a first wall (3.1) of the channel (3) located closest to the decorative area (2) and a second wall ( 3.2) of the channel (3) located further away from the decorative area (2).
Por otro lado, y como se puede ver en la figura 4, cada una de las ranuras (3.3) define un ala (3.1.1) de retención abatible conectada a la primera pared (3.1) a través de una zona de unión (3.1.1.1) flexible. Dicha zona de unión (3.1.1.1) flexible establece una bisagra que permite el abatimiento del ala (3.1.1) de retención a lo largo de dicha zona de unión (3.1.1.1) flexible . On the other hand, and as you can see in the figure 4, each of the slots (3.3) defines a folding retaining wing (3.1.1) connected to the first wall (3.1) through a flexible joining area (3.1.1.1). Said flexible joining area (3.1.1.1) establishes a hinge that allows the retention wing (3.1.1) to be folded along said flexible joining area (3.1.1.1).
En un caso particular, y con el objeto de favorecer el abatimiento del ala (3.1.1) de retención abatible, la zona de unión (3.1.1.1) flexible puede estar configurada mediante un debilitamiento de la primera pared (3.1) del canal (3) a lo largo de dicha zona de unión (3.1.1.1) flexible, donde se haya practicado una reducción del espesor de material de dicha primera pared (3.1) . In a particular case, and in order to favor the folding of the folding retention wing (3.1.1), the flexible joining area (3.1.1.1) may be configured by weakening the first wall (3.1) of the channel ( 3) along said flexible joining area (3.1.1.1), where a reduction in the thickness of material of said first wall (3.1) has been performed.

Dicho área decorativa (2) forma parte integra del guarnecido interior (1) de puerta conformado. En primer lugar la etapa a) de disposición de un guarnecido interior (1) de puerta conformado, comprende la operación de fabricación de dicho guarnecido interior (1) de puerta conformado con las características descritas más arriba. Dicha operación de fabricación se puede llevar a cabo mediante un proceso de inyección de plástico o mediante un proceso de termoconformado por ej emplo . Said decorative area (2) forms an integral part of the interior trim (1) of the shaped door. First of all, step a) of arranging an interior trim (1) of the shaped door comprises the operation of manufacturing said inner trim (1) of the shaped door with the characteristics described above. Said manufacturing operation can be carried out by a plastic injection process or by a thermoforming process, for example.
El proceso de inyección se ha considerado especialmente ventajoso puesto que las alas (3.1.1) de retención abatibles del canal (3) se obtienen directamente del proceso de fabricación del guarnecido interior (1) de puerta, de manera que no es necesaria la realización de una operación posterior en la que se configuren las ranuras (3.3) que definen dichas alas (3.1.1) de retención abatibles. Sin embargo, la invención no se limita a dicho proceso de inyección. The injection process has been considered particularly advantageous since the folding retaining wings (3.1.1) of the channel (3) are obtained directly from the manufacturing process of the inner door trim (1), so that the realization is not necessary of a subsequent operation in which the slots (3.3) that define said folding retention wings (3.1.1) are configured. However, the invention is not limited to said injection process.
Una vez fabricado el guarnecido interior (1) de puerta conformado, este se posiciona sobre una cuna (8) soporte que permite el posicionamiento de dicho guarnecido interior (1) de puerta para llevar a cabo el resto de etapas que comprende el procedimiento para el recubrimiento del área decorativa (2) con el revestimiento decorativo (4) . A continuación se lleva a cabo una etapa b) , representada en la figura 3b, de aplicación de adhesivo sobre una cara (2.1) del área decorativa (2) sobre la que se colocará el revestimiento decorativo (4) . Esta cara (2.1) se corresponde con la superficie principal del área decorativa (2) que da continuidad a la cara del guarnecido interior (1) de puerta que situada hacia el interior del habitáculo interior del vehículo. Para esta etapa de aplicación de adhesivo, se utilizan unos medios de aplicación de adhesivo (5) consistentes por ejemplo en un espray de aplicación de adhesivo . A continuación se lleva a cabo la etapa c) , representada en la figura 3c, que comprende la colocación del revestimiento decorativo (4) en correspondencia con la cara (2.1) del área decorativa (2) sobre la que se ha aplicado el adhesivo, con el objeto de que dicho revestimiento decorativo (4) copie la forma del área decorativa (2) . Once the interior trim (1) of the shaped door is manufactured, it is positioned on a support cradle (8) that allows the positioning of said interior trim (1) to carry out the rest of the steps comprising the procedure for the Coating the decorative area (2) with the decorative coating (4). Next, a step b), represented in Figure 3b, of applying adhesive on one side (2.1) of the decorative area (2) on which the decorative coating (4) will be placed is carried out. This face (2.1) corresponds to the main surface of the decorative area (2) that gives continuity to the face of the interior door trim (1) which is located towards the interior of the interior interior of the vehicle. For this adhesive application stage, adhesive application means (5) consisting for example of an adhesive application spray are used. Next, step c), represented in Figure 3c, is carried out, which includes the placement of the decorative coating (4) in correspondence with the face (2.1) of the decorative area (2) on which the adhesive has been applied, in order that said decorative coating (4) copy the shape of the decorative area (2).
Para ello se dispone de un revestimiento decorativo (4) con una forma normalmente rectangular que se coloca sobre el la cara (2.1) del área decorativa (2) . For this, a decorative covering (4) with a normally rectangular shape is placed on the face (2.1) of the decorative area (2).
Dicho revestimiento decorativo como se puede apreciar en el detalle B de la figura 3e representado en la figura 5, puede comprender un laminado de una espuma (4.3) que ofrezca un tacto suave al usuario y un elemento decorativo (4.4), como un tejido, un no tejido o un tejido no tejido, que ofrezca un aspecto estético. A continuación y con el objeto de que el revestimiento decorativo (4) copie la forma del área decorativa (2), se pueden utilizar diversos medios de colocación (no representados), por ejemplo medios de aplicación de vacio o medios de prensado que copian la forma del área decorativa (2) . Dichas técnicas fuerzan al revestimiento decorativo (4) a copiar la forma del área decorativa (2) mediante la utilización de presión. Said decorative coating, as can be seen in detail B of Figure 3e shown in Figure 5, can comprise a laminate of a foam (4.3) that offers a soft touch to the user and a decorative element (4.4), such as a fabric, a nonwoven or a nonwoven fabric, which offers an aesthetic appearance. Next and in order that the decorative coating (4) copy the shape of the area decorative (2), various placement means (not shown) can be used, for example vacuum application means or pressing means that copy the shape of the decorative area (2). These techniques force the decorative coating (4) to copy the shape of the decorative area (2) by using pressure.
Como resultado de dicha colocación del revestimiento decorativo (4), se produce la unión de dicho revestimiento decorativo (4) con el área decorativa (2) a través del adhesivo. As a result of said placement of the decorative coating (4), said decorative coating (4) is joined with the decorative area (2) through the adhesive.
Dicha unión se produce a lo largo de la cara (2.1) del área decorativa (2) . Normalmente la zona del canal (3) no queda unida como resultado de esta operación, debido a la dificultad de acceso del adhesivo al interior de dicho canal (3) . Said bonding occurs along the face (2.1) of the decorative area (2). Normally the zone of the channel (3) is not joined as a result of this operation, due to the difficulty of access of the adhesive to the interior of said channel (3).
Por tanto, la etapa c) de colocación del revestimiento decorativo (4), comprende las operaciones de posicionado, presionado y fijado del revestimiento decorativo (4) sobre el área decorativa (2) a lo largo de la cara (2.1) del área decorativa (2) . A continuación, y con el objeto de asegurar la unión del contorno del revestimiento decorativo (4) a lo largo del canal (3) se lleva a cabo la etapa d) , representada en las figuras 3d, 3e y 3f, de introducción de una primera parte (4.1) del revestimiento decorativo (4), situada en correspondencia con el canal (3), a través de las ranuras (3.3), estableciendo una fijación mecánica entre dicha primera parte (4.1) del revestimiento decorativo (4) y el área decorativa (2) del guarnecido interior de puerta (1) a través de las alas (3.1.1) de retención abatibles definidas por las ranuras (3.3) . El revestimiento decorativo (4) dispone de tantas primeras partes (3.1), como alas (3.1.1) de retención flexibles comprende el canal (3) . Therefore, step c) of placing the decorative covering (4), comprises the operations of positioning, pressing and fixing the decorative covering (4) on the decorative area (2) along the face (2.1) of the decorative area (2) . Next, and in order to ensure the union of the contour of the decorative lining (4) along the channel (3), step d), represented in figures 3d, 3e and 3f, of introducing a first part (4.1) of the decorative coating (4), located in correspondence with the channel (3), through the grooves (3.3), establishing a mechanical fixation between said first part (4.1) of the decorative coating (4) and the decorative area (2) of the inner door trim (1) through the folding retention wings (3.1.1) defined by the grooves (3.3). The decorative coating (4) has so many first parts (3.1), as flexible retention wings (3.1.1) comprises the channel (3).
Por otro lado, además se produce la introducción de una segunda parte (4.2) del revestimiento decorativo (4), situada en correspondencia con el canal (3), en el interior de dicho canal (3) . On the other hand, there is also the introduction of a second part (4.2) of the decorative coating (4), located in correspondence with the channel (3), inside said channel (3).
Dicha introducción tanto de la primera parteSuch introduction of both the first part
(4.1) como de la segunda parte (4.2) del revestimiento decorativo (4) especial se lleva a cabo mediante la utilización de un útil de vestido (6) perimetral que comprende un conjunto de almenas (6.1) y un conjunto de tramos intermedios (6.2) situados entre dos almenas(4.1) as of the second part (4.2) of the special decorative covering (4) is carried out by using a perimeter dress tool (6) comprising a set of battlements (6.1) and a set of intermediate sections ( 6.2) located between two battlements
(6.2) contiguas, representado en la figura 8. (6.2) contiguous, represented in figure 8.
En particular, en el caso de la introducción de la primera parte (4.1) del revestimiento decorativo (4) a través de las ranuras (3.3) establecidas en el interior del canal (3), las almenas (6.1) del útil de vestido (6) perimetral mediante su movimiento de avance en una dirección perpendicular a la superficie principal del guarnecido interior (1) de puerta, fuerzan a la primera parte (4.1) del revestimiento decorativo (4) a introducirse en el interior de dichas ranuras (3.3) provocando el abatimiento de las alas (3.1.1) de retención abatibles en torno a la zonas de unión (3.1.1.1) flexibles conectadas a la primera pared (3.1) del canal (3) . In particular, in the case of the introduction of the first part (4.1) of the decorative covering (4) through the grooves (3.3) established inside the channel (3), the battlements (6.1) of the dress tool ( 6) perimeter by advancing movement in a direction perpendicular to the main surface of the inner door trim (1), force the first part (4.1) of the decorative lining (4) into the interior of said grooves (3.3) causing the folding of the folding retention wings (3.1.1) around the flexible joining areas (3.1.1.1) connected to the first wall (3.1) of the channel (3).
Como se puede ver en el detalle B de la figura 3e representado en la figura 5, el abatimiento de las alas (3.1.1) de retención abatibles en torno a la zona de unión (3.1.1.1) flexible provoca el alejamiento de las alas (3.1.1) de retención abatibles de la segunda pared (3.2) del canal (3), permitiendo la introducción de la primera parte (4.1) del revestimiento decorativo (4) a través de las ranuras (3.3) . As can be seen in detail B of Figure 3e represented in Figure 5, the folding of the folding retention wings (3.1.1) around the flexible joint area (3.1.1.1) causes the distance of the folding retention wings (3.1.1) of the second wall (3.2) of the channel (3), allowing the introduction of the first part (4.1) of the decorative covering (4) through the grooves (3.3).
Una vez finalizada dicha etapa d) como se puede ver en el detalle C de la figura 3f mostrado en la figura 6, las alas (3.1.1) de retención abatibles vuelven a una posición más próxima a la segunda pared (3.2) del canal (3) . Once said step d) is finished, as can be seen in detail C of Figure 3f shown in Figure 6, the folding retaining wings (3.1.1) return to a position closer to the second wall (3.2) of the channel (3) .
De esta forma, se produce en un primer momento el tensado y arrastre de dicha primera parte (4.1), para terminar con la introducción de la misma a través de la ranura (3.3) del canal (3) . In this way, the tensioning and dragging of said first part (4.1) takes place at first, to end its introduction through the groove (3.3) of the channel (3).
Dichas alas (3.1.1) de retención abatibles permiten retener mecánicamente dicha primera parte (4.1) del revestimiento decorativo (4), de manera que una vez que el útil de vestido (6) perimetral, y en particular las almenas (6.1) que forman parte del mismo, se retira de las ranuras (3.3) del canal (3), dicha primera parte (4.1) del revestimiento decorativo (4), permanece retenida a través del ala (3.1.1) de retención abatible. Said folding retention wings (3.1.1) allow said first part (4.1) of the decorative covering (4) to be mechanically retained, so that once the perimeter dress tool (6), and in particular the battlements (6.1) that they form part of it, it is removed from the grooves (3.3) of the channel (3), said first part (4.1) of the decorative lining (4), remains retained through the folding retaining wing (3.1.1).
Por otro lado, debido a la configuración de las alas (3.1.1) de retención abatibles, cuando se tiende a sacar la primera parte (4.1) del revestimiento decorativo (4) de la ranura (3.3), dichas alas (3.1.1) de retención abatibles tienden a cerrarse aún más sobre el canal (3), aumentado la fuerza de retención que mantiene fijada dicha primera parte (4.1) en el canal (3) . Por otro lado, para el caso de la introducción de la segunda parte (4.2) del revestimiento decorativo (4), el útil de vestido (6) perimetral comprende los tramos intermedios (6.2) que permiten la introducción de dicha segunda parte (4.2) en el interior del canal (3) . De esta forma, mediante la combinación de los dos tipos de unión establecidas entre el área decorativa (2) y el revestimiento decorativo (4), la primera de ellas consistente en unión mediante adhesivo establecida entre la cara (2.1) del área decorativa (2) y revestimiento decorativo (4) y la segunda de ellas, consistente en la unión mecánica establecida entre una primera parte (4.1) del revestimiento decorativo (4) y el área decorativa (2) a través de las alas (3.1.1) de retención abatibles del canal (3), se consigue una fijación fiable, que ofrece un buen aspecto y durable a lo largo de la vida útil del guarnecido interior (1) de puerta . On the other hand, due to the configuration of the folding retention wings (3.1.1), when the first part (4.1) of the decorative covering (4) of the groove (3.3) tends to be removed, said wings (3.1.1 ) Folding retention tends to close even more on the channel (3), increasing the retention force that holds said first part (4.1) in the channel (3). On the other hand, in the case of the introduction of the second part (4.2) of the decorative coating (4), the perimeter dress tool (6) comprises the intermediate sections (6.2) that allow the introduction of said second part (4.2) inside the channel (3). Thus, by combining the two types of bonding established between the decorative area (2) and the decorative coating (4), the first one consisting of bonding by means of adhesive established between the face (2.1) of the decorative area (2) ) and decorative covering (4) and the second one, consisting of the mechanical connection established between a first part (4.1) of the decorative covering (4) and the decorative area (2) through the wings (3.1.1) of folding retention of the channel (3), a reliable fixation is achieved, which offers a good and durable appearance throughout the life of the inner door trim (1).
En una variante de la invención no representada, la etapa d) de introducción tanto de la primera parte (4.1), como de la segunda parte (4.2) del revestimiento decorativo (4) en el interior del canal (3), que se lleva a cabo a través del útil de vestido (6) perimetral, permite además ejercer presión sobre el revestimiento decorativo (4) contra el área decorativa (2), con el objeto de que dicho revestimiento decorativo (4) copie de la forma del área decorativa (2) y se lleve a cabo la fijación mediante adhesivo de ambos elementos. Por tanto, en este caso, el útil de vestido (6) perimetral además de comprender las almenas (6.1) y los tramos intermedios (6.2), reproduce la forma del área decorativa (2) del guarnecido interior (1) de puerta. En este caso particular de la invención, la etapa d) además de la operación de introducción del revestimiento decorativo (4) comprende las operaciones de presionado y fijado del revestimiento decorativo (4) sobre el área decorativa (2) y por tanto, en este caso particular, la etapa c) solamente comprende las operación de posicionado del revestimiento decorativo (4) sobre el área decorativa (2) . In a variant of the invention not shown, step d) of introducing both the first part (4.1), and the second part (4.2) of the decorative coating (4) inside the channel (3), which is carried carried out through the perimeter dress tool (6), it also allows to exert pressure on the decorative coating (4) against the decorative area (2), so that said decorative coating (4) copies the shape of the decorative area (2) and fixation by adhesive of both elements is carried out. Therefore, in this case, the perimeter dress tool (6) in addition to comprising the battlements (6.1) and the intermediate sections (6.2), reproduces the shape of the decorative area (2) of the interior door trim (1). In this particular case of the invention, step d) in addition to the operation of introducing the decorative covering (4) comprises the operations of pressing and fixing the decorative covering (4) on the decorative area (2) and therefore, in this particular case, step c) only includes the positioning operations of the decorative covering (4) over the decorative area (2).
