Abstract

The cleaning system for a surface exposed to weather has reaction surfaces arranged in layers (1.1-1.3). It has metallic surfaces and preferably with a copper content which, in combination with water, develop fungicidal and/or bactericidal compounds which dissolve in water, and which act in cleaning the exposed surfaces. At least two layers are held apart by spacers (2), at least in a part-area, to form zones (14) between them to build up moisture and where rain water can flow in and flush them out. The outer layer has a number of openings (6).

Description

Cleaning device for application on a surface exposed to the weather.

The invention concerns a device of cleaning for application on a surface exposed to the weathering, especially a roof, a roof surface, a solar installation surface or a facade, where the device has a plurality of reaction surfaces that They are arranged in layers and have a metal surface, preferably with copper content, and that, in combination with water, generate cleaning compounds, preferably fungicides and / or bactericides, which, dissolved in water, can moisturize the roof less in part.

Cleaning devices are generally known for roofs and, therefore, for surfaces exposed to the outdoor. In particular, patent DE 100 58 855 C1 is recorded. This patent describes a roof ridge element based on copper that presents parallel to the lateral surfaces a moisture conductive capillary plate that should generate interstices capillaries and that should thus suck up water - which accumulates in an upward fold of the sheet provided below - with help of a capillary action between the walls closely juxtaposed that form the capillary interstitium.

The problem with this device is that, to form a capillary interstitium of this class, you have to present a very precise manufacturing to maintain approximately equal the capillary action in a whole region relatively older, then certainly seeking action capillary that some water is aspirated between the interstices, but not being possible a flow of water through the interstices capillaries, since, as a result of surface tension, originates a resistance to the feeding of the circulating water, of so that there is only insufficient water exchange between the hair interstices and the environment, with what substances possibly formed within the capillary interstitium cannot leave abroad in sufficient quantity. For the rest, the essays practical with capillary interstices of this class arranged very together they have thrown the result that it only occurs insufficient efflorescence of material surfaces, with what ultimately prevents substance formation cleaners

Also, the utility model DE is reported 201 04 999 U1. This utility model also reveals an element roof ridge metal that is preferably made from base of copper plates, forming all along the element of roof ridge a chamber that is delimited on the side bottom by a continuous sheet and presenting on the outer side a grid that must achieve an increase action of surfaces. As a result of the symmetric configuration of the ridge element, a chamber is formed on both sides of the roof respective that, according to the idea of the invention there described, must also be filled with a veil or braided Store moisture The practical tests with an execution of this class of a ridge cover have yielded the result that in the chamber formed in this way there is no accumulation volume sufficient, and the duration of accumulation for natural water, since evaporation occurs noticeably too early of eventual humidity.

Therefore, the purpose of the invention consists in in finding a cleaning device for application on a surface exposed to the weather or on a roof, which presents an improved surface cleaning action compared to the devices described above.

The inventor has recognized that, to improve the Self-cleaning action of cleaning devices for your application on a surface exposed to the weather, a optimal combination between collected and stored humidity and the proportioned reaction surface of metal, especially of copper, taking into account, in addition, that it is also necessary a possibility of sufficient discharge of the accumulated liquid Meanwhile as soon as a new contribution from Water, that is, a new rain. Also, it seems to be essential in this case that the configuration of the cleaning device, especially from the chambers in which it receives moisture, it can be made so that the solar radiation that strikes outside do not heat the inner chambers too much to avoid a premature evaporation of moisture from the chambers.

Apart from the need for a water flow sufficient, it is also necessary to procure through a distance enough between the layers that the surfaces or the reaction surfaces come sufficiently in contact with air to generate sufficient surface efflorescence, since This is a precondition for the effectiveness of the device cleaning. Very small distances between layers are unfavorable in an area where capillary forces enter into action between the layers. You should choose distances that, after a while tolerable, may present a sufficient efflorescence of the surfaces.

Accordingly, the invention proposes to improve the cleaning device itself known for application on a surface exposed to the weather, especially a roof, a roof surface, a solar installation surface or a facade, the cleaning device presenting a plurality of reaction surfaces that are arranged in layers and have a metal surface, preferably with copper content, and which, in combination with water, generate cleaning compounds, preferably fungicides and / or bactericides, which, dissolved in water, they can wet the roof at least in part. According to the invention, the improvement lies in the fact that at least one top layer is provided, a lower layer and at least one intermediate layer, being separated at at least two layers of each other by means of spacers in at least a partial area of its surface so that they form between the layers are spaces where natural moisture can enter, especially rainwater, and it can be dragged again out.

\hbox{proporciona}

a la humedad acumulada tiempo suficiente para reaccionar con la superficie metálica, preferiblemente eflorescida, y para disolver las sustancias necesarias para la acción de limpieza y extraerlas de la superficie metálica que forma la superficie de reacción. Además, se garantiza con la ejecución según la invención que, al presentarse nuevamente agua, se efectúe un barrido lo más libre de trabas posible de estas cámaras, de modo que las sustancias allí formadas puedan ser llevadas por flotación sin impedimentos hacia fuera y puedan desplegar su acción sobre la superficie que ha de limpiarse.By means of this execution, the volume of water that is present is deliberately distributed over several humidity planes that are formed by means of spacers, the humidity accumulated in these chambers being relatively little heated, for example by solar radiation, as a result of the layers located on it , especially when the spacers establish only an almost punctual contact with the adjoining surface, so that

 \ hbox {provides} 

at the accumulated humidity sufficient time to react with the metal surface, preferably effloresced, and to dissolve the substances necessary for the cleaning action and extract them from the metal surface that forms the reaction surface. In addition, it is ensured with the execution according to the invention that, when water is presented again, a scan is made as free as possible of these chambers, so that the substances formed therein can be carried by flotation without impediments outwards and can deploy its action on the surface to be cleaned.

Although it is not absolutely necessary, it may be, however, it is very advantageous that at least the outer layer is provided with a plurality of perforations, so that also the rain that falls on the surface of the cleaning device can penetrate relatively unimpeded to the underside of the respective layer. Correspondingly, not just the layer outer, but also the intermediate layers arranged below she and eventually even the bottom layer may be provided of perforations to also generate permeability there, if well the perforations should be small enough to prevent a simple projection of liquid through it. So, a compromise between accumulation action and impediment of the flow of liquid.

To achieve this goal, the different layers they can be arranged parallel to each other or in shape conical, being especially advantageous that the distance between different layers increase upwards. In any case, it is advantageous that the surface of the sum of the input openings is greater than the surface of the sum of the openings of exit.

The spacers between the layers can be configured, for example, so that, if possible, they establish a punctual or at most linear contact with the surfaces that must be kept at a distance from each other, it should be noted that the spacers do not have to inevitably consist of separate individual elements, but the layers described can be manufactured with useful die cutters and spacers can then be integrated into the surface of the different layers by a corresponding conformation of the surface and possibly a cut of openings. Just put a limit at configurations of the spacers, but it is advantageous that produce an increase as strong as possible in the reactive surfaces by means of such spacers.

Another execution of the cleaning device provides according to the invention that at least one layer provided below is present for at least one layer arranged on it a flange and / or a hinge that linearly support the at least one disposed layer over at one end of it, preferably at least in certain sections. This execution makes it possible for them to be placed several layers one over another, protecting the ridges formed to the respective layer arranged above against slipping down or well, in case a hinge is provided between the layers, making possible also a deployment of the different layers. Since the cleaning device according to the invention is exposed to outdoor weather and, therefore, also to fouling by dust or deposition of nearby tree leaves, can be advantageous separate from each other or deploy the different layers and be able to perform thus a cleaning in the intermediate zones. In addition, it is the possibility of generating also by means of a conical display of the individual layers a snow slide insurance so soon as the snow on a roof sets in motion inclined, so that it is braked by the layers of the device cleaning when separated from each other.

The cleaning device according to the invention can be adapted to the most different forms of roofs and surfaces, a cleaning device of this kind may also be configured, for example, as a roof ridge or a roof ridge cover. In addition, the contour and / or surface of the cleaning device can be adapted to the contours and / or surfaces of known roof plates and tiles. Regarding the possible forms of roof plates, tiles and other roof covers or surfaces, reference is made by way of example to the Internet pages www.braas.de or www.creaton.de . In particular, it is also to be noted that the roof cleaning device of the aforementioned class can also be used on hurdle roofs or roofs that are covered with slate, roof cardboard, corrugated Eternit plates or the like, an application being especially possible for solar installations or other glass or plastic roofs.

Regarding the number of intermediate layers existing, it has been proven in the region of Bavaria that it is especially favorable the number of two intermediate layers, is say, a total of four layers, although it can be equally enough that the cleaning device has only one intermediate layer, that is, a total of three layers. To optimize the distance between the different layers may be advantageous here that not distances between individual layers remain the same, but that intermediate spaces of different height are generated, of so that water retention as optimal as possible is possible in accordance with the existing weather conditions in certain regions

It has also been found that it is advantageous that at least between two layers, preferably between all layers, the water inlet gap, that is, the gap in the layers that are directed in the opposite direction to the flow direction of water, is greater than the water outlet gap, that is, the gap from which the rainwater comes out in the assembled state of the cleaning device; this is almost always the bottom edge of The different layers.

Another improvement in the effectiveness of the device cleaning can be achieved by doing that in the spaces formed by the layers are arranged copper material with a surface strongly enlarged, preferably a granulate and / or a flocculate and / or a braided and / or conglomerate of pellets and / or fibers of copper and / or sintered parts With the use of such means of increasing the surface strongly expands the reaction surface proportionate, so that greater effectiveness of the cleaning device

The different layers can be arranged with lateral offset and / or height relative to each other. In addition, the layers may have at two opposite ends folds directed upwards and / or downwards. The layers can be individually arranged loosely one on top of the other or at least the outer layer and the bottom layer, preferably all the layers, can be joined together, being able to apply known joining techniques, such as screws, nails, rivets, welding joints or bonding joints. At least the bottom layer, preferably all layers, can be adapted to the three-dimensional shape of the surface of roof sections and / or roof tiles and / or solar installations or other surfaces exposed to the weather. In order to achieve a secure fixing of the cleaning device, at least the lower layer may have fixing elements and / or fixing clamps. Such fasteners may at least partially consist of plastic and may be equipped so that they are snagged in at least one of the layers, preferably the infectious layer.
rior.

A special equipment of the spacers it may consist of these being configured as a braid and / or tissue, so that the layers remain elastically at distance between them and at the same time however they occur heat flows as small as possible between the different layers.

According to the invention, these layers can be manufactured in one piece, generating the intermediate spaces here corresponding preferably by bending down and creased.

The different layers of the cleaning device they can be manufactured, on the one hand, from thin sheet, preferably copper plate, but, on the other hand, there is also the possibility of forming at least one layer of the device cleaning by means of a sheet, preferably a sheet of copper. If all layers of the cleaning device are formed to sheet base, this then has the advantage that the layers are adapt very easily to the outer contour of the respective tiles covered. In this context, it is stated that the so-called sheets do not They differ basically from thin plates. However, in The meaning of this application is understood as a surface sheet Widely flexible metal that, due to its own weight, adjusts at least to the large area contour of a configuration of a tile under the sheet. Also, within the framework of the invention can also include a sheet or layer that is constituted by several strata, not having to be inescapably metallic all strata, but only the stratum accessible to moisture must present a metallic property to generate the cleaning action.

An advantageous embodiment of the invention resides also in equipping the cleaning device with at least one layer preferably with all layers, on whose surface they are stamped cavities and prints; preferably this can be carried out by die-cutting, especially by lamination with rollers In this context, it should also be mentioned that it can be especially advantageous the manufacturing of the cleaning device according to the invention by means of at least one process of die cut

As an alternative to a sheet of this class, you can also use as a layer a braid or a fabric without leaving of the framework of the invention. In this execution it is advantageous that, Due to the hollowed structure of a fabric or braided, they occur relatively very large surfaces relative to the surface projection, which react with moisture, and can be improved well even more the effectiveness of the device.

Additional features and advantages of the invention follows from the following description of examples of preferred execution with reference to the drawings and by means of the claims.

Figure 1 shows a cleaning device according to the invention for application on a roof ridge tile 3. The cleaning device is made up of four layers 1.1-1.4 that hug the roof ridge tile 3 to a large extent on the upper side, each layer extending on both sides of the roof ridge tile. Different
layers present here punched bumps 2 that act as spacers between the different layers. On the lower side of the respective layers, flanges 8 are bent upwards against which the respective layer located above with its longitudinal side can be supported. Due to the configuration of the different layers with the spacers shown, sufficient spaces 14 are generated between the layers in which rain or dew water can penetrate from above through openings 6 of the layers and this water can accumulate in the intermediate spaces The layers are configured here so that, as a result of the spacers, there is only a very small thermal contact between them, so that the solar radiation does not lead to a rapid evaporation of the water located in the intermediate spaces 14, so that sufficient time and surfaces are available to form the chemicals that lead to roof cleaning. In the left side of the figure, inserts 7 are also shown in intermediate spaces 14 which consist of material containing copper or copper and which, apart from the surfaces of the different layers, produce an increase in the surface of reaction and also generate some water retention action. On the other hand, perforations have been shown on the left side in a reinforced manner so that the incident rain can easily penetrate the different layers.

Figure 2 shows a cleaning device similar 1 on a roof ridge tile 3, although here only the bottom layer 1.4 is configured so that it hugs to the entire roof ridge tile 3, while the other layers 1.1-1.3 arranged on it are arranged exclusively in lateral position and are prevented from slipping down by connecting elements 5 in the form of screws, nails, Rivets or similar. The configuration of the different layers corresponds here substantially to the representation of figure 1, can also be introduced here additionally between the layers, in the spaces 14 between these layers, constituted inserts, for example, by copper grains, agglomerated lumps, elements sintered, braided or similar.

Figures 3 and 4 show two devices of cleaning 1 that are arranged on flat tiles 9, being these are also configured with four layers. The equipment of the layers correspond to figures 1 or 2, also being generated here again intermediate spaces 14 between the different layers 1.1-1.4 in which moisture can accumulate.

Furthermore, in figure 3 it has been shown that between the lowermost layer 1.4 and the intermediate layer 1.3 located above it is incorporated a fabric that also presents a water retention function and an increase function of the surface, this insert should consist 7 conveniently in a copper material so that they can form in an increased manner the desired reaction products. Fits record in this regard that it is more favorable to accommodate such inserts in the lower strata, since these inserts provide a increased heat flow between the upper and lower layers, if Well this one, deep down, is undesirable. However, when several well separated layers are arranged on the upper side thermally, the preferred effect of water accumulation and surface increase predominates then against conduction thermal

Figure 4 shows a variation of the layers with respect to its spacers in the sense that the first layer 1.1 located below is of flat construction and has 2 spacers that have been manufactured based on a good plastic insulator, so that between the lower layer 1.4 and the layer 1.3 located above there is only a small thermal contact. Of this mode, through the roof tile below, the least possible amount of heat in the layers above. Similarly, the outer layer 1.1 is also separated from the layer intermediate 1.2 located below by hooked spacers consisting of plastic

Together, a combination is thus obtained optimal between water retention and simultaneous isolation against solar radiation acting from outside. If water is fed from up in increased quantity to the cleaning device, the water accumulated so far can exit through the slits or openings of Exit 12 existing in the deepest area of the different layers or between the extreme support points of the layers and can thus produce a roof cleaning located in the direction of the flow or other surfaces.

The cleaning devices shown in this document represent only selected examples, having also chosen simple geometric shapes for the sake of a simplest representation. This concerns, on the one hand, the surface on which the cleaning devices rest and also to the structure and shape of the spacers, the which, of course, can be constructed in different ways by means of a correspondingly configured die cutting tool, being able to use very different ways. It is generally advantageous to in this respect that at least the lower layer adapts to the respective shape of the covered surface, especially of the tiles located below, although it can also be advantageous in part that work with spacers in front of the surface to be cleaned located below. The configuration of the spacers themselves, in if they conform themselves from the different layers, can be especially favorable when driving to large additional areas and at the same time generate possible a small heat transmission to the next layer that has to hold off.

It should be noted that in particular, but not exclusively, the embodiments of figures 1 to 4 are suitable for fabrication also with relatively sheets flexible, especially copper sheets, since the sheets are especially suitable for, despite its flexibility, maintain a distance between the layers by structure formation shallow with highlights or nipples, without requiring a own rigidity Regarding the use of such sheets, it is possible then also perform individual clipped preforms at the foot of work and adapt them effortlessly to the particularities of the respective roof.

Figures 5a to 5d show sections transverse through possible contours of the device cleaning. Thus, the contour of Figure 5a corresponds, for example, to a pan in Frankfurt and the contour of figure 5b can take advantage, for example, for use on an Eternit roof curly. Figures 5c and 5d represent simple contours slightly curved or flat of a cleaning device such as that can be used on relatively flat surfaces.

Of course, all of them can also be used known tile contours and all contours of all known roof shapes.

Figures 6a and 6b show two profiles a example title of a roof cleaning device, seen from above, showing figures 7a to 7c sections longitudinally transversely to the direction of the ridge a through the contour of cleaning devices such as those they use, for example, in the area of the ridge.

Figure 8 is intended to represent another variant of a cleaning device according to the invention which rest here on a roof surface with flat smooth tiles or roof bricks 9. The cleaning device has four layers of copper sheet fixing layers 1.1 to 1.4 in substantially parallel positions by means of spacers 2 laterally mounted.

The spacers can consist, for example, in plastic, so there is only a small transmission of heat between layers. Above, rainwater can penetrate when draining into the openings formed 6 and accumulates between the layers 1.1 to 1.4 in intermediate spaces 14, where there is time enough for the reaction with the copper surface effloresced to so that the necessary chemical reactions can take place. In the extreme area of the cleaning device are formed by the Consecutive splicing not completely watertight layers exit slits through which the accumulated water can flow out towards the surface to be cleaned. Also, in this area slits, small openings may also be made or perforations in the extreme area of the respective layer, preferably in the area of the flange 8, to make the exit of water is produced evenly uniformly Distributed

Section A-A of Figure 8 It is represented in figure 9. Here you can see especially well the outline of the spacers 2 presented to Sample title These can be provided on one side or two sides, for fixing the layers, of slits in which the layers are introduced and thus fixed at their distance required As an alternative to the slits shown in conical configuration, these can also be configured in parallel and rectangular shape.

In the form of execution shown here the spacers are built so that they rest directly on the surface of tile 9 and also maintain the layer less than a certain distance from the roof surface to generate sufficient efflorescence and the passage of water correctly dosed The spacers are fixed here laterally with lugs 10 on or between tiles 9. For fixing between the spacer 2 and lug 10 is used here - represented to the right - for example, a fixing element 13 in the form of a nail, screw or rivet. As shown on the left, the lug 10 fits into a slot in the spacer 2. It fits even mention that the length of the different layers is the same and, therefore, a offset equal to the width of the flange 8.

Figure 10 shows a cleaning device on a flat roof surface 9 with also four layers equipped with lateral spacers, in longitudinal section. Do not However, the top three layers are framed here laterally completely by spacers 2, running the layers down and coming together in Conical shape. Due to lateral framing it is especially retained Well the water in the spaces formed by the layers. The layer lower 1.1 is here of construction significantly longer than the of the remaining layers and can be so, for example, imprisoned or hooked with a tile arranged above.

In addition, the illustration shown may also considered only as a part of one side of a ridge element of symmetrical configuration, in which the layer lower 1.1 covers the roof ridge or even the way she same.

In addition, it should be noted that this kind of execution, when installed in the lower part of a roof, is especially suitable as a snow brake or assume additionally at least this function. They are possible too combinations of layers arranged in parallel and conical.

Figure 11 shows, for a better illustration, a three-dimensional representation with wire model of roof cleaning device of figure 8, while the Figure 12 shows a three-dimensional representation of the device roof cleaning of figure 10.

A section is shown in figure 13 transverse through a roof cleaning device similar to that of figures 8 or 10, but with construction layers different. On the left the lower layer is shown without perforations with a sintered insert located above. About this a finely perforated layer 1.2 is found and on it a layer 1.3 of coarser perforations, followed by the top layer 1.4 perforated with large holes or slits 6. Also, between two layers an elastic bonding element 11 is arranged - here with spring elements - which prevents the spacers from sliding 2 separating one from the other and thus helping to hold the layers with security. It should be noted that the position and the number of joining elements.

The right side of Figure 13 shows another Layer arrangement 1.1 to 1.4. The top layer 1.4 is here from closed construction, and beneath it is a surface Sintered 1.3 strongly structured and uniformly thick, followed by a sintered layer 1.2 that is more construction thick in the center than on the edge, followed by a layer heavily perforated bottom 1.1.

It should be noted that, as a result of conditions different climatic conditions, the optimal arrangement of different layers, generally being the objective of the arrangement achieve a water accumulation as long as possible, paired with good efflorescence conditions and good drag by flotation of the generated reaction products.

According to the invention, the cleaning device can be obtained by die-cutting a flat copper material, it should be noted that by die cutting all the manufacturing procedures that fall under this term - see a in this respect, for example, DIN 9870 or "Der Werkzeugbau "(The Construction of Tools), 1997, ISBN 3-8085-1202-4, especially chapter 1 "Stanztechnik" (Technique of Die cut). Figure 14 shows by way of example a device of cleaning of this class in longitudinal section, which has generated four layers perforated by a multiple folded towards down and folded. One side of a ridge element is represented and the opposite side is not shown symmetrically ready. For example, this kind of configuration and manufacturing can also be used for other types of cleaning device, for example for executions similar to those of the figures precedents

A special variant is shown in Figure 15, which represents a cleaning device 1 consisting of three layers folded in a V-shape and plugged into each other, of which Two layers are perforated construction. As spacers the folds arranged below work here, the which support each of them on the bottom layer and thus determine the distance and alignment of the layers.

Figure 16 shows a longitudinal section a through a roof cleaning device 1 folded only one once it forms a kind of bag in which a layer is plugged in intermediate 1.3 with integrated spacers 2. The intermediate layer it is plugged in the lower area into a slot that serves here also of spacer 2. In addition, they are located down in the bag folded forming layers 1.1 and 1.3 small openings of outlet 6 that let the stored liquid out after a corresponding reaction time and when pushed by new water of rain.

Figure 17 shows once again a variant of a cleaning device on a flat roof surface with four layers 1.1 to 1.4 equipped with side spacers 2, in longitudinal section. To better fix layers 1.2 to 1.4 have mounted on each side two spacers that are snagged them themselves in the lower layer 1.1. The lower layer 1.1 is maintained by the ends of the spacers 2 at a distance from the surface underneath and hooked against slipping down with the tile arranged above.

A roof ridge element, which is configured as a roof cleaning device and that by its construction corresponds basically to the cleaning device of Figure 16 is shown in Figure 18 in representation Three-dimensional as a wire model. These curved surfaces they can be obtained here also very easily and cheaply by die cutting procedures

Figures 19 and 21 show other executions to example title of the cleaning device according to the invention, especially for the multiplicity of forms and executions of spacers 2. Thus, figure 19 shows a device of cleaning similar to that of figure 17, but here the different layers 1.x are not the same length, but are shortened from the layer lower 1.1 to upper layer 1.4. In this way, it is achieved that, when there is a rain between moderate and reduced, all intermediate spaces 14 between the layers are filled with moisture, even without openings in the surface of the layers. This rules so much for stable layers of sheet metal as for flexible sheet layers. In addition, a variation of the spacers 2 is shown. These they are constituted here by a combination of elements 2.2 spacers and a 2.1 connecting element introduced through of the spacer rings. For example, they can be taken as simple spacer elements intermediate discs, rings or either wedges of very different materials, such as plastic, rubber or metal.

If, as shown in Figure 19, they are used distance elements of the same height on one side, you get then a distance of parallel layers. In figure 20 it represents the way in which a conical path of 1.x layers by means of different spacer elements height.

Simplifying, in figure 21 it has been represented that with a correspondingly wide support surface of the 2.2 spacer elements is also sufficient to install in each side just a spacer 2 to get a fix Enough of the layers. A corresponding measure is shown also in figure 22 for a non-parallel path of the layers 1.x. Also, it is shown here at the bottom end of the layer lower 1.1 a beaded or downward fold 15 - represented with dashed line - in which layers can be entered superior to achieve additional fixation.

The last figure 23 finally shows another device according to the invention in which with the aid of a process of die cut have been embedded in the surface of the layers 1.2-1.4 integrated spacer elements 2.2 and these do not have to be installed individually. At free space produced from the spacers is installed a centering element 2.3 which also serves as a kind of washer for fixing element 2.1. This one can be manufactured, for example, based on plastic or it can be Built as a metal sleeve with washer located above. In principle, there are a large number of different possibilities of distance junction of the different layers that remain within the scope of the invention.

Overall, it should be noted that all cleaning devices shown and all devices cleaning according to the invention can be of both flat configuration as well as wavy or curved, both in the longitudinal direction as in the transverse direction, without leaving the scope of the invention. As a complement, it is also stated that all layers shown in the execution examples may be provided of highlights and cavities and / or openings, without leaving the scope of the invention.

Regarding the die cutting process mentioned in the request, it is stated that this must be understood as all manufacturing procedures cited in DIN 9870, sheet 1, October 1974 edition, including DIN sheets additional ones cited there in the alphabetical index with eventually other references.

Therefore, it is jointly disclosed by the invention. exposed a cleaning device that is suitable, due to the especially favorable moisture accumulation and, at the same time, to the sharp increase in the reaction surface, in conditions very different climatic conditions, to produce surface cleaning exposed to the weather. In this regard, it should be noted especially that such cleaning devices may not serve as Exclusive way to clean roofs, but clean also additionally other exposed surfaces, being possible here, for example, of solar installations, glass fronts, glass roofs or facades of buildings
