Description

Method for producing an edge profile and furniture part

The present invention relates to a method for producing an edge profile for a narrow surface of a plate-shaped material, in which an edge band extending in a longitudinal direction is provided with a decoration and in which the edge band is provided with a three-dimensional structure.

Furthermore, the invention relates to a furniture part with a plate-shaped material having at least one narrow surface and an upper side and a lower side, and having at least one edge profile.

Furniture panels are known from the prior art, which are provided with a wood decor and have a three-dimensional structure, which is adapted to the wood decor. In other words, the structure is congruent with the decor, that is, a part of the structure, in particular recesses or projections, each extending congruently with a decorative element. A structure adapted to a décor, for example wood decor, is also referred to as a synchronous structure or synchronous pore or named "embossed-in-register." Decor and structure are part of a coating that has been applied to a plate-shaped material, in particular a wood-based panel ,

For the production of such decorative coated furniture panels, various methods are known. Thus, EP 2 700 511 AI describes a method for producing a plate-shaped furniture part, in which printed with a wood decor and impregnated with resin papers with the top and bottom of a

Be pressed wood material board. For pressing, structured press plates are aligned with the decor, thus embossing a decor-synchronous structure in the two plate surfaces. Another method is described in EP 1 645 339 A1. Here, the three-dimensional structure is not embossed, but applied to the decor. For example, a directly printed carrier plate is provided with a transparent seal on which a structure is printed using a matt or colored varnish. Such a structure is also called paint pore. Also with this

According to one embodiment, the method may be in the form of a synchronous structure, that is, a structure that is synchronous with the structure.

It is also known to stick on the narrow surfaces of a plate-shaped material, such as a furniture panel, an edge profile, also called edge band. This serves as a visually appealing conclusion of the furniture panels on their narrow surfaces, on the other hand, the wood-based material is protected from moisture and shocks. There are different types of

Edge profiles or edge bands known.

On the one hand paper-based edge profiles are known which consist of a layer structure of one or more resin-impregnated papers. The resin is, for example, melamine resin or other thermosetting resin. As papers, at least one decorative paper, which is printed with a decor, and optionally one or more core papers used.

Edge profiles of this type are used for example for edging narrow surfaces of coated wood materials such as particleboard, MDF, HDF, plywood and veneer boards. The finished furniture panels can in turn be used as carcass components, fronts, countertops etc.

In the paper-based edge profiles, the respective decor can be printed before or after the impregnation of the respective paper. The thus provided with the decor layer structure can then be polymerized by compression or mere drying. It is also known to have a three-dimensional structure

impress, for example, by embossing a layer before pressing or by embossing the entire layer structure in the course of pressing. The edgebands produced in this way can in principle also be produced in a width greater than the final width, for example in widths of 50 to 150 cm. In this case, the edge bands are then cut lengthwise into strips, with the narrower edge bands thus produced then forming the respective edge profile.

In addition to the paper-based or duroplatischen edge profiles described above, thermoplastic edge profiles, also called extrusion profiles are known, which also serve for decorative narrow-surface coating of wood materials such as chipboard, MDF, HDF and lightweight panels and take both a protective and a design function. The edge profiles are made by extrusion of a thermoplastic material, for example ABS (acrylonitrile-butadiene-styrene) and are usually solid throughout. These edge profiles can be used in the production of furniture for kitchens, bathrooms, offices, etc. Due to their great robustness, they can also be used in trade fair and shop construction.

The extrusion of an edge band, which later forms a thermoplastic edge, can be done in various ways. That's how you differentiate the

Single-strand extrusion on the one hand and the calender process on the other.

In single strand extrusion, an extrusion tool is used which in the

Essentially the profile of the finished edge, so the final edge profile has. In the calender method, however, the extrudate, for example, by means of a slot die, fed to a calender between the rollers, a relatively wide edge band is formed, which is optionally later in turn divided according to the desired edge width in strips.

Edge bands produced by extrusion can also be provided with a three-dimensional structure, with a separate embossing roller usually providing the structure imprinted in the still soft, doughy state. However, it is also known to allow the edge band to cool first and then to heat so strongly by means of high-energy radiation, for example infrared radiation, that a

Embossing roller can then impress the structure. Also in the calendering process, a three-dimensional structure can be embossed, namely by structuring one of the calendering rolls. In both cases, that is both in the

Single-strand extrusion as well as the calendering process, a decoration can also be applied to the edge band, which can be done before or after the embossing of the edge band.

The decor printing is carried out in the edge profiles described above, for example by means of a digital printing process in which a print head of a laser printer or inkjet printer prints the decor on the surface to be printed. Such a method for printing an edge profile is described for example in DE 198 23 195 C2.

Paper-based and thermoplastic edge profiles can in principle be provided with a wood or stone decor. For furniture parts that are particularly good to imitate a part of solid wood or stone, it is preferable to choose a paper-based or thermoplastic edge with a decor that corresponds to the top of the furniture part.

It is an object of the present invention to provide a furniture part which is further improved in terms of optical and haptic properties.

The previously derived and indicated object is according to a first teaching of the present invention in a method for producing an edge profile for a narrow surface of a plate-shaped material, for example a

Wood-based panel or lightweight board, in which an edge band extending in a longitudinal direction, in particular an endless band, is provided with a decoration, which in particular has at least one decorative element, and

in which the edge band is provided with a three-dimensional structure, which has in particular at least one recess or a protrusion, achieved in that the decor and the structure are arranged such that the structure is at least substantially congruent with the decor.

Thus, according to the invention, at least part of the structure, in particular one or more recesses or projections, in each case extends congruently with one

Decorative element of the decor. It has been recognized that, in particular in the case of furniture parts which are provided with a synchronous structure on both sides, that is to say both on their upper side and on their underside, the use of such an edge profile which likewise has a synchronous structure has further improved

Similarity with a material to be imitated, such as wood brings.

Especially for large narrow areas, such as these, for example

Kitchen worktops are provided, the impression of a solid wood panel is achieved, especially if the decor and structure of the coating on the top and / or bottom coincide with the coating on the narrow surface. Preferably, it is even conceivable, in a plate-shaped material, which is provided for example with a coating of a wood decor, two parallel to each other

To provide narrow surfaces with a decor and a synchronous structure, which is identical to the decor and structure of the top or bottom of the plate, and to provide the two other mutually parallel narrow surfaces with a different decor and a different synchronous structure, the

For example, conveys the impression of end grain. The upper side or lower side and the two first parallel narrow sides would then give the impression of longitudinal wood, so that overall hardly any differences to real solid wood are recognizable. In the following, various embodiments of the method according to the invention for producing an edge profile will now be described, which are also the subject matter of the subclaims. According to a first embodiment of the method according to the invention, it is provided that the edge band is produced by extruding a thermoplastic material and optionally subsequent dicing in the longitudinal direction of the edgeband. Under an edge band so on the one hand understood an extruded and not subsequently divided band, on the other hand but also resulting from a cutting of the extrudate band. Both variants of an edge band can, if they are provided with a decor and a decor-synchronous structure, form an edge profile in the sense of the invention. Alternatively, the edgeband can also be pressed or dried, thereby curing, on or off

multilayer paper-based layer construction, wherein the paper or papers are impregnated with a thermosetting resin.

According to a further embodiment of the method according to the invention, it is provided that the edgeband is provided with the structure within a period of time after its production, in particular extrusion, in which the plastic material of the edgeband does not yet have the final dimensional stability. According to this embodiment, therefore, the structure is embossed in the still soft or doughy state in the extrudate.

According to a further embodiment of the method according to the invention, it is provided that the edgeband is provided with the structure within a period of time after its production, in particular extrusion, in which the plastic material of the edgeband already has the final dimensional stability. It is thus also conceivable first to allow the extrudate to cure completely, if necessary to temporarily store it, in particular as a roll product, and subsequently to heat it at least superficially and thereby in the region in which the embossing is to take place. soften. The heating takes place in particular by means of high-energy radiation, for example infrared radiation.

According to a further embodiment of the method according to the invention it is provided that the edge band is first provided with the decor and then with the structure. What is meant is that at a predetermined point of the edge band in a first step the decor is provided, in particular by printing the top, that is the later visible side, for example by means of a digital printing or gravure printing method, wherein in a subsequent second step at this (previously provided with the decor) place the structure is imprinted.

According to an alternative embodiment of the method according to the invention it is provided that the edge band is first provided with the structure and then with the decor. It is therefore also conceivable that in a first step at a predetermined point of the edge band, the structure is first embossed and then in a separate second step, the decor is applied, the order (imprint) in particular or only in the recessed sections and not done in the protruding sections of the coinage. Finally, it is also conceivable to provide a different order, for example in a different color, in the protruding sections than in the recessed sections of the embossing. In this way, a decore-synchronous structure can be produced in a particularly simple manner. According to a further embodiment of the method according to the invention, it is provided that the decor is applied to the edge band by means of intaglio printing, in particular indirect intaglio printing, using one or more impression cylinders. By a gravure printing method is meant a printing technique in which a printing cylinder has protruding portions and recessed portions, this printing cylinder is provided with ink, for example, by immersing it in a dye bath, so that both the protruding and the recessed portions come into contact with the paint, then the paint is stripped with a doctor blade or a wiper from the protruding portions so that there is only color in the recessed sections, and finally the impression cylinder and the surface to be printed edge band are pressed together The color of the recessed sections on the surface of the

Edges transfers. A corresponding decor is repeated depending on the circumference of the respective printing cylinder. In principle, this process can also be carried out using a plurality of such pressure cylinders, in particular with

different colors and / or different shapes of recessed portions and / or different circumferences.

According to a further embodiment of the method according to the invention, it is provided that the structure is embossed into the edge band by means of one or more embossing rollers. The embossing roller (s) has, similarly to the above-described impression cylinders, protruding and recessed portions, the protruding portions being immersed in the edge band, thereby producing the embossment. Here, too, several embossing rollers can provide one embossing in succession, with the shape of the protruding or

recessed portions and / or the extent of the embossing rollers can differ. In principle, it is also possible to provide a roller without its own embossed structure, in which case a structuring film or the like (structured-initiating paper) is guided along between the roller and the extruded edge band. According to a further embodiment of the method according to the invention, it is provided that the at least one embossing roll is a calender roll of a calender. A calender consists of a plurality of calender rolls arranged one below the other and / or next to one another, which are adjacent to or adjacent to each other

Calender roll (s) are spaced by a predetermined gap. The extrudate is passed between and formed by a plurality of pairs of adjacent calender rolls. If one of the calender rolls is one Embossing roller, an embossing is automatically provided in the surface of the edge band or extrudate. Preferably, the embossing roll is a calender roll of the last pair of calender rolls through which the extrudate passes. According to a further embodiment of the method according to the invention, it is provided that the circumference of the printing cylinder and the embossing roller (s) is selected such that when the edge band comes into contact with impression cylinder (s) and embossing roller (s), the decor and structure are at least in one another Be substantially overlapped. Should it be due to tolerance nevertheless to a possible slight offset between the decor and the structure in

Come in the longitudinal direction, changes (without countermeasures) the size of the

Offset in the longitudinal direction not, because pressure cylinder and embossing roller (s) always run synchronously to each other due to the coordinated size. In order to achieve such synchronicity, provision is made in particular for the circumference of the embossing roll (s) to correspond to the circumference of the printing cylinder or to an integral multiple of the circumference of the printing cylinder or cylinders.

Additionally or alternatively, it may also be provided that the circumference of the printing cylinder or cylinders corresponds to an integral multiple of the circumference of the embossing rollers.

In the case of an offset, it is also conceivable that an automated

Control device is provided which detects the offset in the longitudinal direction between the decor and structure (early) and the feed rate of the edge band and / or the rotational speed of one or more

Regulated printing cylinder and / or one or more embossing rollers.

According to a further embodiment of the method according to the invention it is provided that the decor by means of digital printing (using a

Device for digital printing, in particular using a printhead, especially inkjet printhead or laser printhead) is applied to the edge band. If the edgeband is paper-based

Edge band is, it is also conceivable to print the decor first on a decorative paper of the later layer structure, the order before or after the

Impregnating the decorative paper can be done with the thermosetting resin.

Subsequently, the decorative paper thus printed is pressed in the layer structure or dried.

According to yet another embodiment of the method according to the invention, it is provided that a printing device for digital printing or the printing cylinder or one of the impression cylinder or the embossing roll or one of the embossing rollers or a separate marking device on the edge band several times, in particular at regular intervals, provides a marker. A marking may mean a graphic (for example printed) or a three-dimensional (for example embossed) marking. By means of such markings, a regulation of the respectively following impression cylinders and / or embossing rolls can be effected in a particularly simple manner, such that the imprint of the respectively subsequent printing

Printing cylinder or the embossing of each subsequent embossing roll always has the same distance to the nearest mark.

According to a further embodiment of the method according to the invention, it is provided that the respective marking is provided as a separate marking on the edge of the edge band or on the back (the side not visible in the later mounted state) of the edge band or is integrated into the decor and / or the structure "Separate marking" means that the marking is applied independently of the decor and / or of the structure in a separate step, but in principle also a certain defined position of the repeating decoration or the repeating structure can form a marking. A marking can be provided in particular preferably at the edge of the edge band, if the edge band is divided in the course of its further production still lengthwise, wherein preferably such a wide edge strip of

Edge bands is separated, that at the remaining edge band no

Mark is more recognizable. If, on the other hand, the edge band is no longer trimmed laterally, it may be preferable to provide the marking on its rear side, so that the marking is concealed later in the assembled state of the edge profile. In principle, however, the marking can also be integrated in the decor and / or the structure, in particular as part of the decor and / or the structure, so that the marking can not be recognized as such by a viewer (so-called "hidden registration marking").

According to a further embodiment of the method according to the invention it is provided that the respective marking, in particular by means of a

Scanning device, such as optical scanning device, is detected and by a control device for controlling the feed rate of the

Edgeband and / or the printing speed of a device for digital printing and / or the rotational speed of the pressure cylinder (s) and / or the embossing roller (s) and / or to adapt the digital decoration to be printed

(Decor data on a computer) is used. The regulation takes place

Mark detects and transmits a corresponding signal to the control device. In particular, it is conceivable that the control device compares the position of the respective marking with the angular position (relative to the strip surface) of the printing cylinder (s) and / or the embossing roller (s) and with reference to FIG

Performs a comparison. For this purpose, a marking may also be provided on the respective printing cylinder and / or the respective embossing roller, in particular on the cylinder base surface of the respective printing cylinder or the respective embossing roller, this marking likewise being provided by a scanning device, For example, optical scanning device, are detected and a corresponding signal can be transmitted to the control device.

According to an alternative embodiment of the method according to the invention it is provided that the control device, the position of the respective on

Edge band provided marking with the position of the device for

Digital printing, in particular of the print head, (relative to the strip surface) compares and performs a comparison based on the comparison result. The above-described control and the associated adjustment can additionally also a displacement of the respective printing cylinder or the respective embossing roller or the edge band to be printed or embossed in

Transverse direction (orthogonal to the longitudinal direction) include, whereby a displacement between the decor and the structure in the transverse direction can be compensated or prevented.

The previously derived and indicated object is further according to a second teaching of the present invention in a furniture part

with a plate-shaped material having at least one narrow surface and an upper side and a lower side, and

with at least one edge profile,

achieved in that the edge profile is produced by a method as described above. According to one embodiment of the furniture part according to the invention it is provided that the top and / or bottom of the plate-shaped material is provided with a coating having a decor and in particular a three-dimensional structure, which is preferably at least substantially congruent with the decor of the coating of the plate-shaped material , The furniture part can therefore also on the main pages (top and / or bottom) have a decor-synchronous structure, such as a wood decor with appropriate wood structure. - -

According to a further embodiment of the furniture part according to the invention it is provided that the decor of the coating of the plate-shaped material corresponds to the decor of the edge profile and / or the structure of the coating of the plate-shaped material of the structure of the edge profile. Preferably, therefore, the structure in the region of the top side or bottom side surface and the narrow surface is identical. This is also preferred for the decor. In the case of a wood decor, the coating of the upper side or lower side and the edge profile can thereby visually and haptically simulate the surface of longitudinal wood.

According to an alternative embodiment of the furniture part according to the invention it is provided that the decor of the coating of the plate-shaped material of the decor of the edge profile and / or the structure of the coating of the

plate-shaped material is different from the structure of the edge profile. In the case of a wood decor, the edge profile that differs in decor and structure from the coating of the main surface (s) in this way can emulate the look and feel of the end grain surface.

In particular, it can be provided that the decor and structure of the coating of the plate-shaped material represent the decor and structure of longitudinal wood and decor and structure of the edge profile decor and structure of end grain.

In order to achieve a particularly realistic impression, it can also be provided that an edge profile produced in the manner described is applied to two narrow sides striking a corner of the plate-shaped material, wherein both edge profiles have a decore-synchronous structure which, at least in one respect to the each end of the edge profile adjacent portion or completely identical, wherein an offset in the direction perpendicular to the plane in which the upper and lower edge of the narrow surface extends, between the decorsynchronous structure at the end of the one edge profile and the decorsynchronen structure at the end of the other edge profile at most 0.5 mm, preferably at most 0.35 mm, particularly preferably at most 0.2 mm. This applies in particular to all corners of a plate-shaped material, in which two edge profiles meet with a decorsynchronous structure. As a "corner" in this context, the edge is referred to, in which the two

Narrow surfaces meet and extending from the top to the bottom of the plate-shaped material.

There are now a variety of ways to design the inventive method and the furniture part of the invention and further education. In this regard, reference is made on the one hand to the claims 1 and 19 below

On the other hand, the description of embodiments in conjunction with the drawings. In the drawing: show a schematic representation of the production of an edge profile according to a first embodiment of the invention

Figures 2 and 3 show further variants of the method. Figures 4a) and b) show a furniture part 14 of a plate-shaped material 2, a corresponding

Edge profile 1 has. FIGS. 5a) and b) show an alternative

Embodiment of a furniture part 14 with an edge profile. 1

The various variants of the method shown in FIGS. 1 to 3 for producing an edge profile 1 are based on the following common basic principle.

Thus, in the method according to the invention, first of all, one is transformed into one

Longitudinal direction L extending edge band 3 in the form of an endless belt

provided or manufactured. The production can be carried out, for example, by extrusion of a thermoplastic or pressing a layer structure of thermosetting plastic (resin) impregnated papers.

The edge band 3 is provided during or after its production both with a decoration 4 and with a three-dimensional structure 5. In this case, the decor 4 is produced by a partial application of paint, so that areas provided with color 4a adjoin unprinted or otherwise printed areas. The areas provided with color 4a each form a decorative element 4b.

The structure 5 can be produced either by providing depressions 5a or projections 5b on the edge band 3, wherein the depressions 5a or

Projections 5b are limited by at least one edge 5c. Recesses 5a can be formed, for example, by embossing and protrusions 5b by application of material, e.g. Paint application, generate.

Whether the edge band 3 first with the decor 4 and then with the

three-dimensional structure 5 or first with the three-dimensional structure 5 and is then provided with the decor 4, is secondary to the basic principle of the present invention. The order can vary depending on the specific case and desired result. As will be explained below with reference to the exemplary embodiments in FIGS. 1 to 3, in the method according to the invention it is essential that the decor 4 and the structure 5 are arranged in such a way that the structure 5 is at least in the

Substantially congruent with the decor 4 is. According to the invention, therefore, a so-called decorsynchronous structure 5 is generated. "Essentially" means that, ideally, part of the structure 5, in particular said recess 5a or said projection 5b, is congruent with the decorative element 4b of the decoration 4, but slight displacements due to tolerance or a slight offset in the longitudinal direction L or transversely thereto can not be ruled out, however, by means of a control device 13 which will be described below, a possible offset can be prevented.

As already indicated, the edge band 3 can basically consist of a single-layer or multi-layered layer structure of papers impregnated with a thermosetting resin. In this case, the decor 4 can also, at least partially, be applied to one of the layers of the layer structure, for example to a resin-impregnated or not yet resin-impregnated paper, in which case subsequently the edge strip 3 is produced from the layer structure, for example by the mentioned pressing. In the following, however, the method will be explained by way of example with reference to FIGS. 1 to 3 for an edge profile 1 in which the edge band 3 consists of a thermoplastic material.

FIGS. 1 and 2 schematically show an extruder 18 for a single-strand extrusion which produces an edge band 3. In contrast, FIG. 3 shows an extruder 18 'of a calender 8. 1 schematically shows a method in which the extruded edge band 3 is provided with a decoration 4 in a first step and subsequently with a structure 5 in a subsequent step. The extruded edge band 3 is for this purpose in the longitudinal direction L first passed past a pressure cylinder 6 and then to an embossing roller 7. With the printing cylinder 6 is by means of a

Gravure printing method several times partially applied color 4a on the edge band 3 on the front side. The areas provided with color 4a form with the remaining surface of a decoration 4th

In the case of FIG. 1, the downstream embossing roller 7 then impresses depressions 5a between the areas provided with ink 4a. The recesses 5a together form a structure 5. In this case, the respective recess 5a extends congruently with the respective decorative element 4b, which is formed by the area provided with the color 4a. In this way, a decorsynchronous structure 5 is created.

FIG. 2 schematically shows a method in which the extruded edge band 3 is likewise initially provided with a decoration 4 and subsequently with a structure 5. Here, however, the ink 4a of the decoration 4 is applied by a print head 9, for example, ink jet print head 9, by means of a digital printing method.

The three-dimensional structure 5 is by means of a print head 9 'in

Digital printing produced by the print head 9 'plastic material, such as colored or colorless and / or matte or glossy paint, applied between the color 4a areas provided. The material applied by the print head 9 'here has a higher layer thickness than the paint 4 a previously applied by the print head 9, so that projections 5 b are formed here, which form the structure 5. - -

For a particularly good result it can also be provided that the structure 5, in particular the structure 5 produced by digital printing, is replaced by an optical one

Detection device [not shown], for example, a camera detected and the decor pressure to the determined position of the structure 5, based on the

Lengthwise L, is adjusted. The reverse case is also conceivable, in which first the decoration 4 and then the structure 5 are provided on the edge band 3, wherein the decoration 4 is detected by an optical detection device [not shown], for example a camera, and the embossing of the structure 5 is indicated the determined position of the decoration 4, with respect to the longitudinal direction L, is adjusted.

In the process in FIG. 3, the extruded edge strip 3 is guided and formed between several calender rolls 7 and 7 'after leaving the extruder 18'. In one of the calender rolls 7 and 7 'is in this

Embodiment to an embossing roll 7, which impresses a structure 5 in the edge band 3 similar to in Fig. 1.

To optimize the embossing result, various other measures are conceivable. Thus, the structure 5 stamping calender roll 7 is here part of the first pair of rollers 7/7 ', with which the extruded edge strip 3 after exiting the extruder 18' comes into contact first, whereby the edge band is still relatively soft. The calender roll 7 is also relative to the extruder 18 '.

in particular arranged and / or the extruded edge strip 3 is in particular so out of the extruder 18 'outgoing, that the extruded edge strip 3 by at least 90 °, preferably by at least 135 °, more preferably by at least 180 ° around the formative calender roll 7 around and so for a particularly long time with the structuring roller 7 in contact.

Downstream of the calender 8 is a printing cylinder 6 similar to that shown in Fig. 1, which also applies in the gravure printing color 4 a on the edge band 3. In this case, the color 4a, however, in the previously by the

Embossing roller 7 produced recesses 5a of the structure 5 introduced. Except for - -

Recesses 5a is not a color or any other color which was then applied separately (not shown).

Thus, according to the invention, the recesses 5a forming the structure 5 or

Projections 5b synchronously (congruent) with the respective decorative elements 4b, that is to say with the regions 4a of the decoration 4 provided with color 4, various measures are conceivable.

On the one hand, it may be provided that the circumference of the respective impression cylinder 6 and the circumference of the respective embossing roller 7 are selected such that, if the

Edge band 3 comes into contact with the respective impression cylinder 6 and the respective embossing roller 7, the decor 4 and the structure 5 with each other (at least in

Essentially) be covered. In this case, the degree of overlap between decor 4 and structure 5 does not change. This is achieved, on the one hand, in that the circumference of the respective embossing roll 7 corresponds to the circumference of the respective printing cylinder 6, so that printing cylinder 6 and embossing roll 7 run at the same rotational speed or unwinding speed.

On the other hand, as shown in FIG. 1, a separate marking device 10 is provided which automatically provides at regular intervals over the length L of the edge band 3 marks 11 on the edge band 3, which can be used for control purposes. In Fig. 1, the markings 11 are impressed. However, it is also conceivable to print markings 11. Such markings can also be provided in the exemplary embodiments in FIGS. 2 and 3.

The markings 11 are provided in FIG. 1 by way of example on the rear side, that is to say the side facing away from the decor 4 and the structure 5, of the edge band 3.

In principle, the markings 11 but also elsewhere,

For example, be provided on the edge of the edge band 3 and / or on the upper side and / or within the decor 4 and / or within the structure 5. The respective marking 11 is detected in FIG. 1 by way of example by a scanning device 12, here an optical sensor 12, and by a control device 13 for controlling the feed rate of the edge band 3 and / or the

Rotation speed of the embossing roll 7 used. In the case that the printing cylinder 6 is connected downstream of the embossing roller 7, as shown by way of example in FIG. 3, the respective marking 11 is preferably used for controlling the

Rotation speed of the printing cylinder 6 used.

The controller 13 compares the detected position of the respective one

Mark 11, for example, with the determined angular position of the printing cylinder 6 and the embossing roller 7 relative to the edge band surface and leads based on the comparison result an adjustment of the rotational speed of the

Pressure cylinder 6 and the embossing roller 7 through when an offset between the decor 4 and structure 5 exceeds a certain setpoint.
