Description

The invention relates to a method for producing panel-shaped building elements, in particular floor elements.

Surface coverings, for example floor coverings, come in a wide variety of designs. Panel-shaped building elements are common, in particular floor elements in the form of laminate with support panels made of compressed fibrous materials. A multi-layer wear layer is usually provided on the upper side of the carrier plate. Panel-shaped components with a wear layer or top layer made of real wood are also very popular and beneficial in terms of living physiology. Such components spread a natural indoor climate, are pleasantly warm underfoot and compensate for fluctuations in humidity in the room air, thereby contributing to a healthy indoor climate.

A backing can be applied to the underside of the panel-shaped components. This is used for dimensional stability and moisture barrier. Depending on the application of the panel-shaped structural elements, impact sound insulation can also be provided on the underside.

To connect the panel-shaped components to one another, they are provided with connecting means. In addition to tongue and groove connections, so-called click systems are mainly used today. These are mechanical connecting means on the grooves and on the tongues, which come into snapping engagement with one another in adjacent components in a surface covering. This enables the components to be laid without glue. In addition, the formation of gaps in the laid surface covering due to expansion and shrinkage processes should be avoided.

The production of panel-shaped components, whether components such as panels for floor coverings or for wall or ceiling coverings, takes place in a production process in which a large-area starting panel, preferably made of a high or medium-density fiber material, forms the multi-layer structure with decorative or decorative elements. Wear layer, sealing and balancing receives. The starting panel is then subdivided into panel-shaped components. The components are separated from the large-format original board by saw cuts. The side edges of the components are then profiled in order to form the locking means on their longitudinal sides and head sides.

Process for the production of plate-shaped components in the form of panels are in DE 199 63 203 A1 or the WO 2005/060507 A2 described.

From the WO 2004/074597 A1 discloses a method for profiling panel-shaped components. These are cut out of a starting panel and then provided with a tongue and groove profile on the long sides.

the EP 1 048 423 A2 shows a method and a machine for longitudinal profiling of panel-shaped components. Complex tongue and groove profiles can also be milled with this machine.

In the production of panel-shaped components, high demands are placed on the angular accuracy of the components on the long sides and the top sides or the transition from the long sides and the top sides. Since the necessary angular accuracies cannot be produced with the usual profiling systems, or can only be produced with great effort, tile-shaped components, particularly those with square dimensions, are rather rare. In particular, there are hardly any glue-free square panel-shaped components on the market.

Proceeding from the state of the art, the invention is based on the object of demonstrating a rational method for the production of panel-shaped structural elements which are advantageous in terms of component geometry and design.

According to the invention, this object is achieved in a method according to the measures of claim 1.

Advantageous configurations of the method according to the invention are the subject matter of the dependent claims, as is a panel-shaped component produced by a method according to the invention and the use of the panel-shaped components produced according to the invention.

A method according to the invention for the production of panel-shaped components, in particular floor elements, provides for the following steps:

• - providing a large format output plate;
• - feeding the starting board into a separating device and separating the starting board into several strips;
• - feeding the strips into a profiling device and profiling the strips along two opposite parallel longitudinal sides and forming connecting means on the longitudinal sides of the strips;
• - Assembling several strips by means of the longitudinal connecting means to form a large-format intermediate plate;
• - Feeding the intermediate plate into a separating device and separating the intermediate plate transversely to the longitudinal extent of the strips into a plurality of component strips;
• - Feeding the component strips into a profiling device and profiling the component strips along two opposite parallel longitudinal sides and forming connecting means on the longitudinal sides of the component strips.

The method according to the invention makes it possible to produce plate-shaped structural elements that are advantageous in terms of their component geometry. In particular, the panel-shaped components have a higher angular accuracy. The higher manufacturing accuracy is particularly advantageous for the production of square components. The advantages of the process are particularly evident when using high-performance profiling systems, in which the workpieces are guided past the profiling tools on a transport chain or belt. When manufacturing products with a profile on all four sides, such systems usually have tolerance values with regard to the angular accuracy, which are generally not sufficient for square components with a click profile. Such squares with glue-free connection techniques have so far been difficult to lay. The invention eliminates these disadvantages by means of the method and the panel-shaped components produced according to the method.

A parent slab is a large sized slab of a specified length and width. The length and/or width is significantly greater than the dimensions of the components to be produced, in particular their width. A starting panel with a standard dimension has, for example, dimensions of 2.60 m×2.10 m. Of course, other large format dimensions are also possible.

The starting panel advantageously already has the multi-layer structure of the finished panel-shaped components.

A strip is a rectangular intermediate product separated from the original panel with a length which corresponds to the length or width of the original panel, depending on whether the original panel is guided lengthwise or transversely through the separating device. The strips divided from the starting panel can all have the same width. However, it is also possible for the starting panel to be separated into strips with different widths.

An intermediate panel is a large format panel composed of strips. The strips are joined together via the connecting means, in particular clicked together. The strips of a starting board can be joined together to form an intermediate board. It is also possible to assemble an intermediate plate from strips that come from different original plates. Furthermore, it is possible for strips of different types to be put together, which in particular have a different surface configuration or a different surface design from one another.

A component strip is a rectangular panel or a plank-like format separated from the intermediate plate. Such component strips have a length and a width that is significantly smaller than their length. After the intermediate plate has been separated by saw cuts, the component strips are unprofiled on their longitudinal sides.

The non-profiled long sides of the component strips are then machined and provided with fasteners.

A panel-shaped component can be a component strip which is profiled and provided with connecting means on all four sides, ie on the two opposite parallel long sides and on the opposite parallel head sides.

A panel-shaped component can also be a component that has been created by dividing the profiled component strip. For this purpose, the component strip is disassembled by releasing the interconnected connecting means and separated into panel-shaped components. The components have connecting means on all sides. In particular, such components have a rectangular configuration. Such individual plate-shaped components are particularly preferably square.

An advantageous aspect of the invention provides that the intermediate plate is rotated by 90° relative to the longitudinal extent of the strips before it is fed into the separating device.

The intermediate board is assembled from the individual strips cut from the original board. The strips are provided with connecting means on two opposite, parallel longitudinal sides. The strips are joined together using the connecting means. In particular, the strips are clicked together if the connecting means are designed as click or snap-in connection elements. These profiles are preferably profiled in one piece from the carrier plate. However, two-part click connections are also possible, for example connections with inserted plastic slides or the like.

This intermediate plate is then rotated 90° relative to the position in which the starting plate is passed through the separator and then fed transversely to the separator. In this way, the intermediate plate is divided into a plurality of component strips transversely to the longitudinal extent of the strips. After the intermediate plate has been separated into component strips, the component strips have unprofiled longitudinal sides. The component strips that are not yet profiled on the longitudinal side are fed to a profiling device and profiled along their two opposite parallel longitudinal sides and connecting means are formed on the longitudinal sides of the component strips. In this process step, the production of a bevel or a bevel coating or edge impregnation can also be easily carried out.

A starting plate which is formed from several layers is advantageously used. This multi-layer starting panel can already have all the layers of the finished panel-shaped component, in particular a carrier layer, a top-side useful or decorative layer and a top-side seal and a bottom-side counteracting layer.

One aspect of the invention provides that a starting panel with a real wood surface or a cork surface is used.

As already mentioned, the connection means are designed in particular with click and/or snap-in connection elements. This enables, in particular, glueless laying of panel-shaped components that are adjacent in a surface covering. The surface covering is stable and highly resilient. The longitudinal sides of the components, in particular the connecting means with click and/or latching connecting elements, can be provided or coated completely or partially with a lubricant or with paraffins or water-repellent agents. The coating is provided in particular on the contact surfaces between the connecting means that come into contact when a surface covering is laid. It can be an edge waterproofing agent, a lubricant or a waterproofing agent. This measure improves the installation and use of the panel-shaped components. In particular, the development of noise, a so-called creaking, between the connecting means is counteracted. This also prevents surface water from penetrating through the connection.

It is possible for the strips to be joined to form the intermediate plate with the addition of adhesive, for example a glue. This supports the joining of the strips to one another and is particularly useful if the strips are no longer to be taken apart after the final assembly, but are designed as plate-shaped components in the form of component strips. The panel-shaped components in the form of component strips are provided with connecting means on their two opposite longitudinal sides and on their two opposite head sides. In this way, the component strips form prepared laying units that can be supplied for further use.

However, the strips can also be joined to form the intermediate plate with the addition of a detachable adhesive, in particular a pressure-sensitive adhesive. Such a detachable adhesive supports the cohesion of the strips in the intermediate plate during its processing, ie the separation of the intermediate plate into component strips and the edge profiling of the component strips. If necessary, the adhesive connection can be loosened again. This can be done at the factory or at the installation site. The adhesive connection can be released mechanically, for example by bending or tilting the components relative to one another and pulling them apart. The adhesive and the adhesive connection are designed in such a way that the connection can be detached without damage.

The method according to the invention is particularly advantageously suitable for the production of panel-shaped components which have a square configuration. Tile formats or rectangular formats with tile-like dimensions are also possible, in particular with dimensions of 30×60 cm or 40×85 cm or 30×120 cm.

An advantageous use of several panel-shaped components provides that these are each prepared as pre-assembled laying units. Such pre-assembled laying units can be assembled component strips which are profiled on all sides and provided with connecting means. It is also possible that individual panel-shaped components are put together to form long-format floorboards. Here, different components can be combined in terms of their surface design and the fiber flow. Such a component strip preferably consists of squares, in which every second square is overturned, ie the fiber orientation is always alternately visible. This leads to a striking look. Through this the possibility of using the components produced according to the invention is further improved in terms of design. This can be supported by the fact that the individual squares have a chamfer, in particular a circumferential chamfer, on their edge regions. The chamfer can be designed as a shiplap. Furthermore, the bevel can be painted in a contrasting color or designed to match the surface of the components.

An essential aspect of the invention relates to panel-shaped components which are designed as component strips, with at least two panel-shaped components being factory-assembled, ie assembled in the factory. Such ready-to-lay panel-shaped components are assembled at the factory from at least two individual components.

Component strips can also be put together like a patchwork. Such a ready-to-lay panel-shaped component in the form of a component strip consists of individual composite components that can consist of the same or different materials with different structures or colors. Applications with linoleum surfaces and decorative surfaces with a stone look are also conceivable. Here, square components with two or more different colors or surfaces can be combined. With two colors, for example, a classic checkerboard pattern is created.

Component strips are preferably composed of at least two panel-shaped components, in particular square components or a combination of rectangular and square components. These individual components can be glued or fixed to one another to secure them. This gluing or fixing can be released mechanically, so that individual squares or panel-shaped components are available again if required. In this way, another design advantage is guaranteed, which enables individual surface images at the installation site.

In this way, a plate-shaped component can be produced from which a so-called braided association can be produced. For this purpose, at least two components of different lengths are combined to form a component strip, one component being overturned relative to the other component, ie rotated by 90°. For example, a strip of components can be composed of two components that are the same width, but where the first component has a length of 1 m and the other component has a length of 25 cm.

Panel-shaped components that have a mosaic orientation as prefabricated component strips are also possible. In this case, square or cube-shaped components are offset, i.e. arranged at right angles to one another.

A component strip composed of a plurality of panel-shaped components or a plank composed of components has a width which corresponds to the length of a first side of a component or to a multiple of the length of a first side of a component. The plank further has a length which corresponds to the length of a second side of a building element or to a multiple of the length of a second side of a building element.

The procedure or the method according to the invention enables the production of panel-shaped components in the form of component strips provided with connecting means all around, or of small-format panel-shaped components on profiling systems with high throughput speeds, which are usually designed for large quantities. This is possible because the strips made from the original panel are profiled and then reassembled to form the intermediate panel. The intermediate plate is then again divided into strips and separated into several component strips. The component strips produced from the intermediate plate are then also profiled at the edges. Overall, in this way, an efficient production of plate-shaped components with high dimensional accuracy, especially angular accuracy, is possible.

The method according to the invention makes it possible to produce panel-shaped components that are advantageous in terms of component geometry and design. In terms of design, it is advantageous that geometrically different formats can be produced and also combined. In addition, components with different optics can be assembled individually or used pre-assembled as component strips.

A preferred aspect provides that a component strip consists of several real wood squares, ie panel-shaped components, with a real wood surface. In particular, with these component strips, every second component has collapsed, ie the course of the fibers is always alternately visible. This can be supported by providing the individual square components with a circumferential chamfer. The chamfer can also be designed as a shiplap. The distance It is possible to paint the bevel in a contrasting color or to design it to match the surface.

A further aspect provides that ready-to-lay component strips are provided, which form a surface patchwork. These can be the same materials with different structures or colors. It is also conceivable that the panel-shaped components combined in a surface covering have different widths or also have an edge or chamfer of a different color. As already mentioned, a checkerboard pattern is also possible.

The separation of the starting plate and the separation of the intermediate plate can take place on one and the same separating device. This is particularly advantageous. For this purpose, the intermediate plate is rotated by 90° before being fed in, so that the strips assembled in the intermediate plate are fed to the separating device transversely to their longitudinal extent.

Of course, the separation of the starting plate and the intermediate plate by saw cuts can also be carried out in separate separating devices.

The production of panel-shaped components 1 ( 9 ), 2 ( 8th ), 3 ( 11 ) and configurations thereof is based on the 1 until 11 described. The panel-shaped components 1, 2, 3 are, in particular, floor elements.

To produce the panel-shaped components 1, 2, 3, a large-format starting panel 4 is provided ( 1 ).

The large-format output plate 4, which can have a length of 2.60 m and a width of 2.10 m, for example, is fed to a separating device 5 ( 2 ). The feeding direction, which corresponds to the direction of the cuts in the longitudinal direction of the starting plate 4, is in the 2 indicated by the arrow S1.

In the separating device 5, the starting plate 4 is separated into strips 6 in its longitudinal direction. In the illustrated embodiment, a total of five strips 6 of the same width are cut from the starting panel 4 . In the 2 the strips 6 produced on or from the starting plate 4 in the separating device 5 are indicated by the dotted lines.

The strips 6 are then fed to a profiling device 7 ( 3 ). In the profiling device 7, the strips 6 are profiled on the longitudinal side and connecting means 10, 11 are formed along the opposite parallel longitudinal sides 8, 9. For profiling, the individual strips 6 are in accordance with the 3 shown arrow P1 guided by the profiling device 7. The connecting means 10, 11 are complementary to each other and in particular click connecting means with grooves and tongues and with click or latching elements on the grooves and tongues.

When profiling the edges of the strips 6, they can also be provided with a chamfer. The bevel can be varnished. Furthermore, when profiling the long sides 8, 9, or after the formation of the connecting means 10, 11, an edge impregnation agent, a lubricant or a waterproofing agent can be applied.

The length of the individual strips 6 corresponds to the length of the starting panel 4. The width of the strips 6 corresponds to the width of the finished components 1, 2, 3 including a profile allowance for the formation of the connecting means 10, 11 on the longitudinal sides 8, 9.

The individual strips 6 profiled on the longitudinal side are assembled into an intermediate plate 12 . For this purpose, several strips 6 are joined together to form the large-format intermediate plate 12 by means of the longitudinal connecting means 10 and 11 . This is done by joining, in particular clicking together, the connecting means 10, 11. In the 4 the joining of the individual strips 6 to form the intermediate plate 12 is illustrated by the arrows Z1, Z2.

The strips 6 produced and profiled from the starting panel 4 can be clicked together manually or by machine. Some glueless click systems require a one-angle movement, others snap together flat. This can be done on appropriate systems in throughput and can be done efficiently.

For reasons of stability, it may be necessary to join the strips 6 together with the addition of adhesive. Depending on the adhesive used, such assembled elements cannot be removed again after the last profiling process, or can only be removed with tools.

It is also possible to use detachable adhesives, which support the joining of the strips 6 in the intermediate plate 12 during further processing, but the adhesive connection can be detachable again without any problems.

An intermediate plate 12 clicked together from several strips 6 is in the 5 shown. The intermediate plate 12 is rotated 90°. The turning process is in the 5 indicated by the arrow D1.

The rotated position of the intermediate plate 12 shows the 6 . In the position rotated by 90°, the intermediate plate 12 is fed to a separating device 5 . The separating device 5 can be the separating device 5 that was also used to make the cuts S1 on the starting panel 4 . Of course, it can also be a second separating device 5 .

The position in which the intermediate plate 12 is guided through the separating device 5 is rotated by 90° in relation to the position in which the starting plate 4 has been guided through the separating device 5 .

The intermediate plate 12 is passed through the separator 5 according to the arrow S2. In the separating device 5, the intermediate plate 12 is separated into a plurality of component strips 13 transversely to the longitudinal extent L1 of the strips 6. The individual component strips 13 are in the 6 on the intermediate plate 12 illustrated by the dotted lines, which correspond to the individual cuts made on the intermediate plate 12.

A component strip 13 is in the 7 shown. After the partitioning of the intermediate plate 12 into the component strips 13 produced in the separating device 5, their parallel longitudinal sides 14, 15 lying opposite one another are unprofiled. The component strips 13 are fed to a profiling device 7 and profiled there along the longitudinal sides 14, 15, whereby connecting means 16, 17 are produced on the longitudinal sides 14, 15 of the component strips 13. The processing operation on the long sides 14, 15 of the component strips 13 and the implementation of the individual component strips 13 through the profiling device 7 is in 7 illustrated by the arrow P2. These connecting means 16, 17 are also in particular connecting means 16, 17 in the manner of a click system with grooves and tongues and click and/or latching elements formed on the grooves and tongues. The profiling device 7 can correspond to the profiling device 7 that has been used for profiling the strips 6. Of course, it is also possible here to carry out the profiling of the component strips 13 along their longitudinal sides 14, 15 on another profiling device 7.

Based on 6 as well as that 8th it can be seen that the intermediate plate 12 has been divided into a total of six component strips 13 . The length of the component strips 13 corresponds to the width of the original starting panel 4, taking into account material removal due to the profiling of the longitudinal sides 8, 9 of the strips 6 and the formation of the connecting means 10, 11.

The all sides provided with connecting means 10, 11 and 16, 17 component strips 13 are in the 8th shown. The component strips 13 have connecting means 16, 17 on their opposite parallel longitudinal sides 14, 15 and connecting means 10, 11 on their opposite parallel head sides 18, 19. In this embodiment, the component strips 13 form the panel-shaped components 2.

The panel-shaped components 2 in the form of the component strips 13 profiled all around the edge can thus be supplied for further use. Each component strip 13 or each panel-shaped component 2 consists of individual square panel-shaped components 1 which are connected to one another by means of the click connection means 10, 11. The connection of the individual panel-shaped components 1 within the strip-shaped, panel-shaped components 2 can be reinforced by adding adhesive in the area of the connecting means. For this purpose, the strips can be joined together to form the intermediate plate with the addition of adhesive, for example a pressure-sensitive adhesive.

The circumferentially profiled component strips 13, which are provided with connecting means, can be clicked apart. Individual square plate-shaped components 1 are obtained, as in FIG 9 shown. The panel-shaped components 1 are square and have connecting means 10, 11 and 16, 17 on all four side edges. These panel-shaped components 1 can be stacked and packaged one on top of the other.

Advantageously, several panel-shaped components 1 can also be combined to form a panel-shaped component 3 in the form of an elongated floorboard. This is based on the 10 and 11 shown and explained.

the 10 shows individual panel-shaped components 1. Every second panel-shaped component 1 is turned over, ie rotated by 90°, as illustrated by the arrows D2, so that the fiber orientation in the individual panel-shaped components is always alternately visible. The components 1 can be clicked together via the connecting means 10, 11 or 16, 17, which are designed to be complementary to one another, on the side edges of the components 1. This is indicated by the arrows Z3, Z4 in the 11 clarified. It is then again a component strip formed from individual panel-shaped components 1 . These panel-shaped components 3 or elongated planks are then packed into a bundle consisting of several such planks and supplied for further use. The advantage of these prefabricated floorboards is that they can be laid more quickly. In particular, laying in a row is easier.

A prefabrication of planks from several panel-shaped components 1 coupled to one another in the factory to form component strips has the advantage that it is not small-scale formats that have to be laid on the construction site, but rather the larger strip formats.

The panel-shaped components 1, 2, 3 produced according to the invention have a high angular accuracy. This is significantly improved compared to conventionally manufactured components. The method according to the invention makes it possible to produce plate-shaped components 1, 2, 3 that are advantageous in terms of component geometry. A major advantage of the method according to the invention is that, in particular, square components 1 can also be produced on standard profiling lines.

The production of a chessboard pattern in a surface covering made of panel-shaped construction elements 2 according to the invention is advantageously possible in different ways. This can be done, for example, by dividing a first starting board 4 into strips 6 . The strips 6 are profiled on their long sides 8, 9 and provided with connecting means 10, 11. A second output plate 4 is rotated through 90° and separated into strips 6 in the separating device 5 in this position. These strips 6 are then also profiled on their long sides 8, 9 and connecting means 10, 11 are formed. The strips 6 from the first starting panel 4 and the strips 6 from the second starting panel 4 are alternately clicked together, i.e. joined together, and an intermediate panel 12 is formed from strips 6 from the first starting panel 4 and strips 6 from the second starting panel 4 . This intermediate plate 12 is then separated into component strips 13 . The component strips 13 produced in this way are profiled according to the procedure according to the invention on their unprofiled longitudinal sides 14, 15 by means of a profiling device 7 and connecting means 16, 17 are formed on the longitudinal sides 14, 15.

The method according to the invention enables the production of high-quality panel-shaped components 1, 2, 3 that are advantageous in terms of component geometry and design in an efficient manner. A particular advantage of the method is the precise production of the panel-shaped components 1, 2, 3, in particular square components 1, as well as strip-shaped panel-shaped components 2 or 3.

Each of the components 1, 2 or 3 has connecting means 10, 11 or 16, 17 running all around on its side edges. Since the side edges of the rectangularly configured plate-shaped components 1, 2, 3 are completely profiled and processed, bevel designs, bevel coatings or bevel covers are also possible.

A further embodiment of a panel-shaped component 3 is shown in the illustration 12 . The panel-shaped component 3 is off two different lengths plate-shaped components 1, 1 'put together. The panel-shaped component 1′ has a rectangular configuration with a length that is at least three times, for example four times greater than the component 1. The fiber structure of the component 1 is overturned in relation to the fiber structure of the panel-shaped component 1′, i.e. rotated by 90°.

the 13 shows a braided bandage 20 made from plate-shaped components 3, as shown in FIG 12 were presented and explained. The braided structure 20 is composed of the panel-shaped components 3, the panel-shaped components 3 being provided as a prefabricated, ready-to-lay unit. In this way, a braided optic is created from panel-shaped components 1, 1', with the panel-shaped components 1, 1' having a different format from one another.
