Description

The invention relates to a panel for use in an assembly of panels which are attached to each other to form a covering, having an upper surface and a lower surface, each of which extends in a different principal plane, and at least an edge portion between these surfaces having a connecting means for joining the panel to the connecting means of another panel, in which the upper surface has a part that descends to the marginal area of the panel.

The invention also relates to a method of manufacturing such panels.

Such panels are known in various embodiments, for example, in the form of laminated floor panels. Such panels are made on a wooden base and have a decorative layer that basically imitates natural panels made of wood or other natural materials.

The task of the invention is to create a panel that imitates a natural panel even better.

To achieve this goal, the invention provides a panel in which the cross-section of the falling part, perpendicular to the edge section of the panel, varies along this edge section.

Due to this characteristic, the falling part has a non-planar structure along the edge area, which improves the natural appearance of the panel. An advantage is that the panels according to the invention provide a better imitation of natural panels than those panels which have a flat, falling part.

The cross-section of the descending part can vary along the length of the edge section unevenly, preferably randomly, for example, to reproduce a rural design.

The falling part may have a remote edge that is positioned against the remote edge of an adjacent panel, the remote edge having a constant position within each cross-section. As a result of this construction, the remote edge of each panel in the panel assembly can be joined to the remote edge of another panel to form a cover such that the cover is compacted between adjacent panels at the remote edges. This prevents water or similar liquids from seeping between the panels. In addition, this design has the advantage that it avoids that part of the marginal area of the panel becomes visible if the distant edges of the adjacent panels have variable positions in different placements relative to each other along the marginal area.

The upper surface of the panel may have a surface finish, and the falling portion may have a plain finished surface. This provides convenience for the use of productive known surface finishing methods, while the falling part can be machined cleanly in a separate process.

Alternatively, the invention relates to a panel for use in an assembly of panels attached to each other to form a covering, having an upper surface and a lower surface, each extending in a different principal plane, and at least an edge portion between these surfaces having a connecting means for joining a panel to a connecting means of another panel, wherein the upper surface has a portion falling to an edge portion of the panel, the falling portion intersecting a major plane of the upper surface along a first line and intersecting a remote edge of the panel that is positioned against the remote edge of an adjacent panels, along the second line, which is characterized by the fact that the length of the first line deviates from the length of the second line. In this embodiment, the first line between the upper and lower part can be used to enhance the natural appearance of the panel.

The invention also provides a method of manufacturing a panel for use in a coating, which has the following operations: - manufacturing a panel having an upper surface and a lower surface, each of which extends in a different main plane, and at least an edge section between these surfaces, - machining the edge section for forming a connecting means for connecting a panel to a connecting means of another panel and for creating a top surface with a part that descends to the marginal area of the panel, which is characterized in that the marginal area is processed so that the descending part has a cross-section, perpendicular to the edge section of the panel, which varies along the edge section of the panel.

This method can provide panels that have the advantages noted above.

The falling part can be provided with a coating such as a film or paint, which has the advantage of protecting the panels from dirt, water and the like. For aesthetic reasons, it can be applied, for example, a design under a country floor.

In a preferred method, a surface finish is applied to the top surface of the panel before the coating is applied to the falling portion, and a release agent is applied to the finished top surface prior to coating the falling portion, and any coating applied to the release agent is removed with anti-adhesive, for example, by removing with a brush. The advantage of these operations is that they simplify the method of manufacturing the panel according to the invention. Since the cross-section of the drop portion along the edge portion varies, the width of the drop portion as viewed in the direction along the edge portion of the panel may vary. As a result, the width of the film or the amount of paint can vary along the edge of the panel. Due to the use of a release agent, the width of the film or paint spray can be locally larger than the width of the falling part mentioned above, because the excess film or paint can be removed easily from the upper surface adjacent to the falling part, for example with a brush . Of course, if there are no problems with adhesion between the coating and the falling part, other methods of providing a coating to the falling part than the use of a release agent can be used.

Preferably, the edge section is machined with a milling tool that is either moved toward and away from the edge section while milling the edge section, or the milling is performed with a rotary milling tool that has teeth along its periphery that are at a variable distance (4) from the center of rotation tool

The advantage of using such technologies is that it provides convenience in using an accelerated production process to obtain the desired structure of the falling part, as described above, and, as a result, minimizes the cost of production.

Next, the invention will be explained with reference to schematic drawings.

In fig. 1 shows two adjacent panels 1 of one of the embodiments of the panel according to the invention. Panels 1 (Fig.1) are attached to each other and can be part of the cover when many panels are attached to each other in this way. In general, panels should be rectangular, or square, or elongated, or in between. But other forms are also possible.

Fig. 2 shows a cross-section of the assembly of panels 1 on an enlarged scale and in more detail. Each panel 1 has an upper surface 2 and a lower surface 3. These surfaces 2 and C each extend in a different principal plane. The main parts (Fig. 2) of the upper surface 2 and the lower surface C are parallel to each other and are placed at a distance in the direction of U. The upper and lower surfaces 2, C are essentially flat surfaces. The panel has an edge section 4 between both surfaces. The edge section 4 has a connecting means for connecting the panel 1 with the connecting means of the adjacent panel 1 (Fig.2). The connecting means is well known in the art, for example, formed by a spike 5 and a groove 6, and is not part of the invention. Of course, it is possible to provide the panel 1 with connecting means of various types and locking means for fastening the panels 1 to each other.

The upper surface 2 includes at least one part 7 that descends, and preferably on all edge areas of the panel. The upper surface 2 (Fig. 2) has an essentially flat surface part 8 and a part 7 that falls. The descending portion 7 is located below the flat portion 8 of the upper surface when viewed in the Y direction.

The upper surface 2 of panel 1 has a surface decoration that imitates natural materials, for example, wood. This surface finish may include a multilayer material of paper layers saturated with resin. The rest of the panel 1 below the upper surface 2 may include a core having one or more layers of material such as MOE, NOE, NT5R, RMS, composites or similar materials and possibly another layer.

According to the invention, the cross-section of the descending part 7, perpendicular to the edge section of the panel, changes along the edge section 4. In Fig. 2, the edge section 4 is extended in the direction 7. It can be seen that the descending part 7 has a non-planar structure when viewed along the edge precinct 4.

This ensures a natural appearance of the panels 1. The embodiment of the panel 1, shown in Fig. 2, has a falling part 7, the cross-section of which varies arbitrarily. Preferably, these changes are random in nature to provide a more natural look to panel 1.

In the embodiment shown in figure 2, the falling part 7 has a remote edge 9 which is placed next to the remote edge 9 of the adjacent panel 1. This edge section 9 is straight and therefore has the same position within the cross-section so as to obtain a corresponding sealing between adjacent panels 1. The remote edge 9 (Fig. 2) has a fixed position relative to the lower surface 3, since the remote edge 9 extends parallel to the lower surface C and the upper surface 2, while the rest of the falling part 7 varies randomly.

The descending portion 7 (Fig. 2) is inclined when viewed from the distal edge 9 to the upper surface 2. This results in the formation of an M-shaped groove between the panels 1 when they are fastened together. In addition, the lower section 10 of the M-shaped groove, which is adjacent to the remote edge 9, has a flat shape and a constant cross-section along the edge section 4. The upper section 11 of the part 7, which is located between the lower section 10 and the flat surface part 8 of the upper surface 2 , has a variable cross-section along the edge section 4. The angle of inclination of the lower section 10 relative to the upper surface 2 is greater than the angle of inclination of the upper section 11 relative to the upper surface 2, for example 35-85" and 15-40", respectively, but it is clear that other angles are also possible. The width of the descending part 7 in the X, Y plane along the edge section 4 can vary, for example, by approximately 2 mm, but of course other sizes are also possible.

The descending part 7 (Fig. 2) crosses the upper surface 2 along the first line 12. The remote edge 9 forms the second line. It can be seen that the length of the first line 12 deviates from the remote edge 9, so as to form the desired non-planar structure of the falling part 7.

According to the invention, the panel 1 described above can be manufactured using the following operations: machining of the edge section 4 to form connecting means 5, 6; providing the upper surface 2 with a part 7 falling on the marginal area 4; and machining the edge section 4 so as to form a falling part 7 with a variable cross-section perpendicular to the edge section 4 of panel 1. The structure of the falling part 7 (Fig. 2) can be obtained by performing the following operations: first machining flat lower section 10 by passing the panel 1 along a milling tool which has a fixed position relative to the passing panel 1 and then passing the panel 1 along a milling tool which moves towards and away from the panel 1 so as to form the upper section 11.

One of the ways to move the milling tool is to move it in a straight line in the X and/or Y directions. This can be done by moving the tool using a motor (induction, linear, etc.), pneumatically, hydraulically, mechanically in a controlled (random) way .

But, it is clear that it is possible to move with the help of piezoelectric elements, or actuators, or linear motors in combination with a magnet, which can be supported by an elastic element. For example, one or more piezo elements can be mounted between the machine caliper and the motor to move the tool(s) in one or more directions. If more than one piezo element is used, these elements can be applied in parallel or in series. In fig. 2a shows the equipment, which includes a milling tool 21 connected to a motor 24, which is mounted on calipers 25 and 26, each of which is movable in directions perpendicular to each other. Each of the calipers is connected to a piezoelectric element 27, 28, respectively, which are mounted on a fixed base. A fixed base for the element 27 may also be formed by a caliper 26 to allow independent movement of the calipers 25 and 26 in the X and M directions to create the desired shape of the falling part 7, panel edges (in this case its upper section 11) when the milling tool 21 and the descending part 7 move along each other.

The falling part 7 can also be produced in one machining operation (Fig. 3a).

Part 7 can be performed with a milling tool 21, which has a fixed position relative to the position of the remote edge 9 of panel 1. The milling tool 21 can rotate around the remote edge 9, as shown by the double arrow in Fig.3. This alternative machining method results in panels having a part 7 that has a non-planar structure between the first line 12 and the remote edge 9 that retains its original shape, in this case a straight line. This method of mechanical processing leads to obtaining panel 1, which is shown in Fig.3b.

It is also possible (Fig. 3a) to rotate the milling tool 21 around a line that is parallel to the remote edge 9 between the remote edge 9 and the upper surface 2. This leads to obtaining a panel 1, which is shown in Fig. 3. In this case, the inclined lower section 10 is processed during the previous mechanical processing operation.

Piezoelectric elements can also be used to create rotary motion of a milling tool by positioning the piezoelectric element(s) appropriately relative to the milling tool or motor to activate them.

Of course, the upper surface 2 of the large plate, which will later be sawn on the panel 1, is first provided with a surface finish 13 before being sawn on the panel 1. After the edge section 4 has been machined to produce the falling part 7, the part 7 is preferably provided a surface treated cleanly, for example, a coating 14 that has a film 14a or paint. This protects the material of the panel 1 from dirt or liquids or the like that may penetrate the panel 1. It also provides the falling part 7 with a color or finish adapted to the finish of the upper surface of the panel.

Since the cross-section of the falling part 7 of the panel 1 along the edge section 4 changes, the required amount of coating 14 or paint per unit length along the edge section 4, which will be provided by the part 7, also changes along the edge section 4. According to the invention, the surface treatment clean, which can be performed on the upper surface 2 before coating 14, is performed on part 7 as well, and the treated clean upper surface 2 is covered with an anti-adhesive before covering the falling part 7. After covering the falling part 7, the coating part 14 can be on top of the part 2, which has already been coated with anti-adhesive, in places near the part 7 (flat surface part 8). The remaining coating 14 on the upper surface 2 can be easily removed from the upper surface 2 together with the release agent, for example by brushing.

Preferably, the anti-adhesive is applied to the upper surface 2 before the machining of the edge area to form the falling part 7, since in this case the part 7 automatically becomes free of the anti-adhesive during machining, and the flat surface part 8 remains covered with the anti-adhesive. These operations are shown in Fig.4. The upper surfaces 2 of the two panels 1 (Fig. 4a) are covered with anti-adhesive on the edges before the mechanical processing of the edge areas 4 and the formation of the falling part 7 (note that the panels in Fig. 4 are shown upside down).

The anti-adhesive can be applied to the upper surface 2 using sprayers 15. Then, on the panels 1 (Fig. 46), the connecting means 5, 6 and part 7 are made. Fig. 4c shows the process of applying the film 14a as a coating 14 to the part 7, that falls

Figures 5a and 56 show the process of applying the film 14a to the descending part 7 in more detail.

In fig. 5a shows the process of pressing a film 14a onto a panel with two separate pressing tools 15 one behind the other as viewed in the direction along the edge section 4. Each of the tools 15 has substantially flat pressing surfaces 16 which can be inclined relative to one another to create a surface 16 pressing that conforms to the shape of part 7, which descends. In fig. 56 shows the process of pressing the film 14a onto the panel 1 by a single pressing tool 15 which has a deformable pressing surface 16 and which can be adapted to different shapes of the collapsible part 7E.

Fig.ba schematically shows a side view of the device for applying film to part 7 of panel 1. Film tape 14a is fed from the left side by drum 17, which has tape 14a. The tape 14a of the film has a width of, for example, 8-10 mm, but other sizes are also possible. The panels 1 are also fed from the left side (not shown) and moved from left to right at the same speed as the speed of the tape 14a of the film.

The device (fig. ba) has press belts 18 and press rollers 19 which press the belt 18 against the film 14a on the descending part 7 of the panel 1. The device also has heating elements 20 to support the process of gluing the film tape 14a to the panel 1. elements 20 can maintain the temperature of the film at a constant level during the gluing process. In addition, fig.ba shows two belts for the case where the part 7 has a lower section 10 and an upper section 11, each of which has different angles of inclination relative to the upper surface 2 (fig.ba). One belt 18 can be used to press the film on the lower section 10, and the second belt 18 can be used to press the film on the upper section 11. This is shown in Fig.6b. Alternatively, the device may have only one endless belt 18, which can be deformed, and press rollers 19, in which the axes of rotation of the rollers 19 may be inclined relative to each other so that the belt 18 presses on the part 7, in which the lower section 10 and the upper section 11 have different angles relative to the upper surface 2 (Fig. 6b). Such a device is shown in Fig. bv. In this device, the orientation of the part of the belt 18 that presses on the film 14A changes along the direction of its movement between the left set of wheels and the right set of wheels (fig.bv).

Another alternative embodiment of the device has a press belt 18, which can press the film synchronously on the lower section 10 and the upper section 11, which have different angles relative to the upper surface 2 (fig.bg). In this case, the belt 18 is made of a more flexible material.

According to the invention, the non-planar structure of the descending part 7 is created by machining the edge section 4 with a milling tool 21, which can be moved in the direction to and from the edge section 4 and at the same time along the edge section 4. This method leads to the creation of the structure of the part 7 , shown in Fig.2. An alternative method was explained above with reference to Fig.Za. It is also possible to use the rotary milling tool 21 shown in fig. 7. This milling tool has teeth 22 on the periphery, which have a variable distance and relative to the center of rotation 23 of the milling tool 21. This provides the possibility of changing the amount of material that is cut by the milling tool by changing the position of rotation of the milling tool 21 during the passage of the panel 1 along the milling tool 21 while the center of rotation remains in the same place.

Another alternative embodiment of the milling tool 29 is schematically shown in fig. 8. This embodiment has a linear electric motor 30, a magnet 31, a flat spring 32, a first support 33 for holding the magnet 31 through the flat springs 32 and a second support 34. The magnet 31 is fixed on the second support 34. The linear motor 30 has a fixed position, e.g. attached to a frame (not shown). The embodiment 29 also has a tool 35, for example, a milling tool, which is fixed on the shaft 36. The shaft is driven by a drive motor 37, in this case through a connecting element 38. The shaft 36 is mounted on a caliper 34 with the possibility of rotation in bearings 39.

When the linear motor 30 is activated, the magnet 31 moves relative to the motor 30. This leads to the appearance of a strong vibration in the direction along the drive shaft 36 of the tool 35. The vibration is supported by flat springs 32. Through the second support 34, the vibration is transmitted to the tool 35. Thanks to the connecting element, the shaft 10 can vibrate, while the drive motor 37 has a fixed position.

The embodiment is not limited to the use of flat springs 32 and equivalent spring elements may be used. It may also be that the magnet 31 is fixed to the frame of the device and the motor is fixed to the second caliper 34. The embodiment 29 is a relatively simple device for the production of the part 7 falling on the edge section of the panel 1, and the cross-section of which changes along this edge section accordingly by.

Preferably, the descending part 7 is milled in two or more operations, for example at 40 and 22.5 degrees relative to the top surface, to ensure that any openings between the two panels are minimized. This reduces the risk of water or similar substances penetrating between the panels.

It is clear from the previous description that the invention provides a panel that is a good imitation of a panel made from natural materials. In addition, the invention provides a suitable method of manufacturing such a panel.

The invention is not limited to the embodiments described above, which may be different within the limits defined by the claims. For example, the first line of the panel may be parallel to the trailing edge, and the portion of the falling portion between the first line and the trailing edge has a non-planar structure. Of course, all milling operations on the edge of the panel are performed in one pass with several milling tools, but other technology is also possible. It is also possible to obtain an irregular shape of the drop part by moving the panel to and from the milling tool instead of the reverse path. pt with and U.
