Abstract

Method involves introducing of carrier medium (5), with approximately 2 to 3 times of speed of sound and under a pressure of 1000 to 7000 bar preferably 3000 bar, into a mixing chamber (16) of a spray head (11) and the granules (6) are supplied to the carrier medium in the mixing chamber. The mixture is then advanced to the focusing unit (19) in the form of spraying jet (12) at a flow rate of 1 to 2 times of speed of sound. The spraying jet is formed from the carrier medium and the granules splash after its withdrawal from the focusing unit. The distance (a) between the spraying head, the covering and the supply pressure of the carrier medium are adjusted in such a manner that carrier medium before impinging on the covering by spraying jet, the granules are separated from the surrounding air and is partly evaporated. The granules effect on the covering and a number of microcraters visible by the human eye are treated in its surface with an observation distance of approximately 150 centimeter. An independent claim is also included for the device for treatment of coverings.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Bearbeitung von Belägen, insbesondere von Fußboden- und Treppenbelägen, aus mineralischen Werkstoffen mit polierten Oberflächen durch ein abrasives Material in Form eines Granulats, das dem Belag mit Hilfe eines Trägermediums unter hohem Druck zugeführt wird.The invention relates to a method and a device for processing coverings, in particular of floor and stair coverings, of mineral materials with polished surfaces by an abrasive material in the form of granules, which is supplied to the covering with the aid of a support medium under high pressure.

Die häufigsten Personenunfälle werden verursacht durch Ausrutschen auf glatten Fuß-, Boden- oder Treppenbelägen. Insbesondere durch gleitfördernde Mittel, die auf glatte Flächen aufgetragen werden, wird die Unfallgefahr noch erheblich erhöht. In den Bereichen des öffentlichen Lebens, aber auch im Privatbereich, werden zu repräsentativen Zwecken oftmals glänzend polierte Fußboden- oder Treppenbeläge verwendet. Diese werden auch in Trocken- und Nassbereichen sowie in den stark gefährdeten Übergangsbereichen eingesetzt.The most common personal accidents are caused by slipping on smooth foot, floor or stair coverings. In particular, by slip-promoting agents that are applied to smooth surfaces, the risk of accidents is significantly increased. In the areas of public life, but also in the private sector, glossy polished floor or stair coverings are often used for representative purposes. These are also used in dry and wet areas as well as in the high risk transition areas.

Zur Erhöhung der Rutschfestigkeit bzw. zur Erzielung von rutschhemmenden Eigenschaften sind bereits verschiedene Verfahren bekannt. Diese Verfahren werden oftmals in Abhängigkeit von den Einsatzbereichen der Fußboden- und Treppenbeläge angewandt.To increase the slip resistance or to achieve anti-slip properties, various methods are already known. These methods are often applied depending on the application areas of floor and stair coverings.

Aus der DE 31 39 427 A1 ist ein Verfahren zur Herstellung einer gewünschten Rauigkeit bekannt, bei dem ein Sandstrahlgut unter hohem Druck mittels Luft auf die Oberfläche des Belages geschleudert wird. Das Sandstrahlgut wird unkontrolliert auf die Oberfläche aufgebracht und erzeugt dadurch unregelmäßige Aufrauungen mit einer starken Mattierung in der Oberfläche.From the DE 31 39 427 A1 A method for producing a desired roughness is known, in which a sandblasting material is thrown under high pressure by means of air onto the surface of the covering. The sandblasting material is applied uncontrolled on the surface and thereby produces irregular roughening with a strong matting in the surface.

Aus der DE 35 45 064 A1 ist das Flammstrahlen von Oberflächen bekannt. Durch Erhitzen der Oberfläche mit einem Brenngas-Sauerstoffgemisch erfolgt in der obersten Gesteinszone ein Sprengen des Quarzes sowie ein Schmelzen von Gesteinsteilen, welche nach dem Erstarren auf der losen Oberfläche haften.From the DE 35 45 064 A1 is the flame blasting of surfaces known. By heating the surface with a fuel gas-oxygen mixture in the uppermost rock zone blasting of the quartz and melting of rock fragments, which adhere to the solid surface after solidification.

Des Weiteren ist aus der DE 39 33 843 A1 die Herstellung einer gestockten Oberfläche bekannt. Durch einen Stockhammer wird mit mehreren gleichmäßig angeordneten Meißelspitzen mit einer bestimmten Frequenz auf die Oberfläche geschlagen. Dadurch entsteht eine Oberfläche mit markanten Vertiefungen, die dadurch stumpf und matt ausgebildet ist.Furthermore, from the DE 39 33 843 A1 the production of a cammed surface known. A mallet hits the surface with several uniformly arranged bit tips with a certain frequency. This creates a surface with distinctive depressions, which is thus made dull and dull.

Diese Verfahren eignen sich nicht für hochglänzend polierte Oberflächen, da durch diese Verfahren der Glanz der Oberfläche entfernt und damit ein anderes ästhetisches Erscheinungsbild erzielt wird.These methods are not suitable for high-gloss polished surfaces, as these processes remove the gloss of the surface and thus achieve a different aesthetic appearance.

Ferner ist aus der DE 195 18 270 C1 ein Verfahren zur Herstellung rutschfester Fußbodenbeläge bekannt, bei dem durch eine Laserstrahlung Mikrokrater erzeugt werden, die für das menschliche Auge unsichtbar sein sollen. Zur Durchführung dieses Verfahrens ist eine kostenintensive Laservorrichtung notwendig, die einen hohen Energiebedarf für den Laserbeschuss erfordert und nur für bestimmte Größen von Fußboden- und Treppenbelägen zur Oberflächenbehandlung geeignet ist.Furthermore, from the DE 195 18 270 C1 a method for producing non-slip floor coverings is known in which by laser radiation micro craters are generated, which should be invisible to the human eye. To carry out this process, a cost-intensive laser device is required which requires a high energy requirement for laser bombardment and is only suitable for certain sizes of floor and stair coverings for surface treatment.

Aufgabe der Erfindung ist es daher, ein Verfahren sowie eine Vorrichtung zur schaffen, die in kostengünstiger Weise die Herstellung einer rutschfesten Oberfläche auf Fußboden- und Treppenbelägen, insbesondere aus mineralischen Werkstoffen, ermöglicht, ohne dass eine nachteilige Beeinträchtigung der repräsentativen, insbesondere hochglänzenden, Oberfläche gegeben ist und die zukünftigen höheren Ansprüche der DIN 51130 nach R9 bis R13 erfüllt. Des Weiteren soll erreicht werden, dass eine gleichbleibende Qualität des bearbeiteten Belages gegeben ist und dass eine Reproduzierbarkeit eines Bearbeitungsergebnisses ohne Schwierigkeiten ermöglicht wird.The object of the invention is therefore to provide a method and a device for the cost-effective manner of producing a non-slip surface on floor and stair coverings, in particular of mineral materials, allows, without any adverse effect on the representative, especially high-gloss, surface is given and meets the future higher requirements of DIN 51130 R9 to R13. Furthermore, it should be achieved that a consistent quality of the treated coating is given and that a reproducibility of a processing result is made possible without difficulty.

Gemäß der Erfindung ist das Verfahren zur Bearbeitung von Belägen dadurch gekennzeichnet, dass das Trägermedium mit etwa 2- bis 3-facher Schallgeschwindigkeit und unter einem Druck von 1000 bis 7000 bar, vorzugsweise von ca. 3000 bar, in eine Mischkammer eines Sprühkopfes eingebracht wird, dass in der Mischkammer das Granulat dem Trägermedium zugeführt wird und das aus diesen gebildete Gemisch nachfolgend in einer Fokussiereinheit in Form eines Sprühstrahls etwa auf eine Strömungsgeschwindigkeit von 1- bis 2-facher Schallgeschwindigkeit beschleunigt wird, dass der aus dem Trägermedium und dem Granulat gebildete Sprühstrahl nach dem Austritt aus der Fokussiereinheit aufgefächert wird und dass der Abstand zwischen dem Sprühkopf und dem zu bearbeitenden Belag und/oder der Förderdruck des Trägermediums derart eingestellt werden, dass das Trägermedium vor dem Auftreffen auf den Belag durch die in dem Strahl befindliche und diesen umgebende Luft von dem Granulat getrennt und zumindest teilweise verflüchtigt wird, so dass das Granulat diffus auf den Belag einwirkt und in dessen Oberfläche eine Vielzahl von für das menschliche Auge bei einem Betrachtungsabstand von ca. 150 cm unsichtbare Mikrokrater eingearbeitet werden.According to the invention, the method for processing coverings is characterized in that the carrier medium is introduced at about 2 to 3 times the speed of sound and under a pressure of 1000 to 7000 bar, preferably of about 3000 bar, into a mixing chamber of a spray head, that in the mixing chamber, the granules are supplied to the carrier medium and the mixture formed from these is subsequently accelerated in a focusing unit in the form of a spray about to a flow rate of 1 to 2 times the speed of sound, that the spray formed from the carrier medium and the granules after fanned out from the focussing unit and that the distance between the spray head and the coating to be processed and / or the delivery pressure of the carrier medium are adjusted such that the carrier medium before impinging on the coating by the present in the jet and surrounding air of the granules separated and is at least partially volatilized, so that the granules diffuse acts on the surface and in the surface of a variety of invisible to the human eye at a viewing distance of about 150 cm micro crater are incorporated.

Zweckmäßig ist es hierbei, den Abstand zwischen dem Sprühkopf und dem zu bearbeitenden Belag mit etwa 70 bis 130 cm zu wählen, die Diffusionsstrecke, in der das Trägermedium durch die in dem Sprühstrahl eingeschlossene und die diesen umgebende Luft verflüchtigt wird, mit etwa 70 bis 80% und die Strecke, in der das Granulat von dem Trägermedium getrennt ist, mit etwa 20 bis 30% des Abstandes zwischen dem Sprühkopf und dem zu bearbeitenden Belag zu bemessen.It is expedient in this case to choose the distance between the spray head and the covering to be processed at approximately 70 to 130 cm, the diffusion distance in which the carrier medium is volatilized by the air enclosed in the spray jet and the air surrounding it, with approximately 70 to 80 % and the distance in which the granules are separated from the carrier medium with about 20 to 30% of the distance between the spray head and the coating to be processed.

Angebracht ist es auch, das Granulat in dem Mischkopf von dem Trägermedium über eine oder mehrere vorzugsweise in Strömungsrichtung des Trägermediums geneigt in den Mischkopf einmündende Kanäle anzusaugen.It is also appropriate to suck the granules in the mixing head of the carrier medium via one or more preferably in the flow direction of the carrier medium inclined into the mixing head opening channels.

Nach einer Weiterbildung sollten auf einer oder beiden Seiten in Verstellrichtung des Sprühstrahls umlaufende Luftwirbel gebildet werden.According to a development circulating air vortex should be formed on one or both sides in the adjustment direction of the spray.

Der aus dem Sprühkopf austretende aus dem Trägermedium und dem Granulat gebildete Sprühstrahl sollte derart aufgefächert werden, dass das Granulat auf dem zu bearbeitenden Belag in einer Breite von etwa 10 bis 20 cm, vorzugsweise mit einem Sprühstrahldurchmesser von 16 cm, diffus aufschlägt.The spray jet emerging from the spray head and formed from the carrier medium and the granules should be fanned out in such a way that the granules diffuse diffusely on the coating to be processed in a width of about 10 to 20 cm, preferably with a spray jet diameter of 16 cm.

Bei einem kontinuierlich in einer Transportrichtung bewegten zu bearbeitenden Belag und einem quer zu dieser verstellbaren Sprühkopf sollten die Verstellgeschwindigkeiten des Belages und des Sprühkopfes derart aufeinander abgestimmt sein, dass der Sprühstrahl achssenkrecht zur Transportrichtung des Belages auf diesen einwirkt.In a continuously moving in a transport direction to be processed coating and a transverse to this adjustable spray head, the adjustment speeds of the pad and the spray head should be coordinated so that the spray acts axially perpendicular to the transport direction of the pad on this.

Die Vorrichtung zur Bearbeitung von Belägen, mittels der dieses Verfahren vorteilhaft anwendbar ist, ist dadurch gekennzeichnet, dass mit einem Abstand von ca. 70 bis 130 cm über dem zu bearbeitenden Belag ein mit einer Mischkammer versehener Sprühkopf angeordnet ist, mittels dem das Granulat in das Trägermedium einbringbar und zu einem Sprühstrahl fokussierbar ist, und dass der Abstand zwischen dem Sprühkopf und dem zu bearbeitenden Belag derart eingestellt ist, dass das Trägermedium vor dem Auftreffen auf den Belag durch die in dem Sprühstrahl befindliche und diesen umgebende Luft von dem Granulat getrennt und zumindest teilweise verflüchtigt wird, so dass das Granulat diffus auf den Belag einwirkt und in dessen Oberfläche eine Vielzahl von für das menschliche Auge bei einem Betrachtungsabstand von ca. 150 cm unsichtbare Mikrokratern eingearbeitet werden.The device for processing coverings, by means of which this method is advantageously applicable, is characterized in that at a distance of about 70 to 130 cm above the surface to be treated, a spray head provided with a mixing chamber is arranged, by means of which the granules in the Carrier medium can be introduced and focused into a spray, and that the distance between the spray head and the coating to be processed is set such that the carrier medium separated from the granules and at least before the impact with the pad by the air in the spray and surrounding it is partially volatilized, so that the granules diffuse acts on the surface and in the surface of a variety of invisible to the human eye at a viewing distance of about 150 cm microcraters are incorporated.

Zweckmäßig ist es hierbei, ein- oder beidseits des Sprühstrahls in dessen Verstellrichtung verlaufend jeweils einen Luftkanal vorzusehen, die durch Leitwände, vorzugsweise in Form eines den Sprühstrahl umgebenden Mantels, gebildet sind, die in der Höhe mit Abstand zu dem Belag und zu dem Sprühkopf aufgehängt sind, wobei die Leitwände etwa parallel zu dem sich auffächernden Sprühstrahl des Gemisches angeordnet sein sollten.It is expedient in this case, in each case on one or both sides of the spray jet in the adjustment direction, to provide an air channel which is guided by guide walls, preferably in the form of a spray surrounding the jacket, which are suspended in height at a distance from the lining and to the spray head, wherein the guide walls should be arranged approximately parallel to the fanning spray of the mixture.

Angezeigt ist es ferner, den Sprühkopf und/oder den Belag derart gegeneinander zu verstellen, dass bei dessen Bearbeitung eine zweifache Überdeckung der bearbeitenden Oberfläche des Belages durch den Sprühstrahl gegeben ist.It is also shown, the spray head and / or the lining to be adjusted against each other in such a way that during its processing a double overlap of the processing surface of the lining is given by the spray.

Das Granulat sollte mit einer Körnung von 0,02 bis 2,00 mm Korngröße dem Trägermedium beigemischt werden, auch sollte das Granulat eine Dichte von mindestens 1 bis 4 Gramm pro cm3 aufweisen.The granules should be mixed with a grain size of 0.02 to 2.00 mm grain size of the support medium, and the granules should have a density of at least 1 to 4 grams per cm 3 .

Als dem Trägermedium beizumischendes Granulat können Quarzsand, Olivin, Granat, Sick, Glaskugeln, Glassplitter oder vergleichbare harte Bauteile, als Trägermedium kann Wasser, Glykol, Öl oder flüssige Gase, wie z.B. Kohlensäure, vorgesehen werden.As granules to be admixed with the carrier medium, quartz sand, olivine, garnet, sickle, glass beads, glass splinters or comparable hard components may be used, as the carrier medium may be water, glycol, oil or liquid gases, such as. Carbonic acid, be provided.

Bei Anwendung des erfindungsgemäßen Verfahrens ist die Gewähr gegeben, dass das Granulat mit hoher Geschwindigkeit auf den Belag aufschlägt, ohne dass dieses dabei z. Bsp. durch eine Wasserschicht gebremst wird, so dass eine intensive Bearbeitung des Belages erfolgt. Durch die Wahl der einzelnen aufeinander abgestimmten Parameter und Verfahrensschritte wird nämlich das Trägermedium zwischen dem Sprühkopf und dem Belag nahezu vollständig verflüchtigt, das Granulat kann somit intensiv auf den Belag einwirken und Mikrokrater, durch die eine Rutschhemmung hervorgerufen wird, erzeugen.When using the method according to the invention, the guarantee is given that the granules strike the pavement at high speed, without this z. For example, is braked by a layer of water, so that an intensive processing of the coating takes place. By choosing the individual coordinated parameters and process steps, namely, the carrier medium between the spray head and the coating is almost completely volatilized, the granules can thus act intensively on the coating and micro crater, which is caused by an anti-slip generate.

Der Einsatz von insbesondere flüssigen Träger-Medien weist ferner den Vorteil auf, dass ein flexibles, anwendungsspezifisches und umweltfreundliches Verfahren zur Herstellung von bedarfsgerechter rutschfester Ausrüstung von glatten, vor allem polierten Oberflächen, gegeben ist. Dadurch lässt sich dieses Verfahren auch an unterschiedlichen Einsatzorten anwenden. Somit ist nicht nur eine stationäre Bearbeitung von Belägen an einem Herstellungsort möglich, sondern dieses Verfahren kann auch mobil eingesetzt werden.The use of in particular liquid carrier media also has the advantage that a flexible, application-specific and environmentally friendly process for the production of non-slip equipment of smooth, especially polished surfaces, is given. As a result, this method can also be used at different locations. So not just a stationary one Processing of coverings at a place of manufacture possible, but this method can also be used on the move.

Bei der Durchführung des Verfahrens ist des Weiteren in vorteilhafter Weise vorgesehen, dass ein gemischter Strahl aus dem Sprühkopf diffus ausgestossen wird. Der gemischte Strahl wird kegelförmig ausgegeben, so dass bei einem nichtbewegten Sprühkopf eine Oberfläche mit einem Durchmesser behandelt oder bearbeitet wird, der um ein Vielfaches größer als der Austrittsdurchmesser des Sprühkopfes der Fokussiereinrichtung ist. Dies wird durch einen kurzen Strömungskanal als Fokussiereinheit ermöglicht, der sich an die Mischkammer anschließt, in der das Gemisch des Strahles erzeugt wird. Turbulenzen in dem in der Mischkammer gebildeten Gemisch bleiben weitgehend in dem Sprühstrahl erhalten, so dass ein diffuser Strahlaustritt gegeben wird.In carrying out the method, it is further advantageously provided that a mixed jet is diffusely ejected from the spray head. The mixed jet is outputted conically, so that when a non-moving spray head, a surface is treated or processed with a diameter which is many times greater than the exit diameter of the spray head of the focusing. This is made possible by a short flow channel as focussing unit which adjoins the mixing chamber in which the mixture of the jet is generated. Turbulence in the mixture formed in the mixing chamber is largely retained in the spray, giving a diffused jet exit.

Mit Hilfe des erfindungsgemäßen Verfahrens bzw. der vorschlagsgemäßen Vorrichtung können somit auf einfache und wirtschaftliche Weise polierte Flächen bearbeitet und rutschhemmend gestaltet werden, ohne dass die Mikrokrater, die dieses bewirken, sichtbar sind. Der dazu erforderliche Bauaufwand ist gering, dennoch ist ein überdurchschnittliches Arbeitsergebnis zu erzielen.With the aid of the method according to the invention or the proposed device, polished surfaces can thus be processed in a simple and economical manner and designed to be non-slip, without the microcraters which cause this being visible. The construction effort required for this is low, yet an above-average work result can be achieved.

Die in Figur 1 dargestellte und mit 1 bezeichnete Vorrichtung dient zur Bearbeitung eines Belages 2, insbesondere eines Fußboden- oder Treppenbelages aus mineralischen Werkstoffen, dessen Oberfläche 3 poliert ist, um in diese, wie dies in Figur 2 gezeigt ist, nahezu unsichtbare Mikrokrater 4 einzuarbeiten, damit der Belag 2 trotz der polierten Oberfläche 3 rutschhemmend ist. Dies wird im Wesentlichen durch Beschuss des Belages 2 durch ein Granulat 6 bewerkstelligt, das mit Hilfe eines Transportmediums 5, beispielsweise Wasser, das zusammen mit dem Granulat 6 mit hoher Geschwindigkeit aus einem Sprühkopf 11 ausgestoßen wird, dem Belag 2 zugeführt wird.The device shown in Figure 1 and designated 1 is used to process a coating 2, in particular a floor or staircase made of mineral materials, the surface 3 is polished to incorporate into this, as shown in Figure 2, almost invisible microcrater 4 so that the pad 2 is non-slip despite the polished surface 3. This is accomplished essentially by bombardment of the lining 2 by a granulate 6, which is supplied to the lining 2 by means of a transport medium 5, for example water, which is ejected together with the granules 6 at high speed from a spray head 11.

Der Sprühkopf 11 ist hierbei in einem definierten Abstand a von ca. 70 bis 130 cm vertikal über dem Belag 2 angeordnet und besteht aus einem auf das Ende eines zur Zuführung des Transportmediums 5 vorgesehenen Rohres 13 aufgeschraubten Halter 14, in den ein mit einer Düse 17 ausgerüstetes Einsatzstück 15 eingesetzt ist. Das Einsatzstück 15 weist eine Mischkammer 16 auf, in die in Strömungsrichtung des Transportmediums geneigt Kanäle 18 zur Zuführung des Granulates 6 in die Mischkammer 16 münden. Des Weiteren ist der Mischkammer 16 eine durch ein Rohrstück gebildete Fokussiereinheit 19 nachgeschaltet, die durch eine auf den Halter 14 aufgeschraubte Überwurfmutter 20 gehalten ist. Aus dem Sprühkopf 11 tritt somit ein zunächst gebündelter Sprühstrahl 12 aus, der sich nach dem Austritt aus der Fokussiereinheit 19 auffächert.The spray head 11 is arranged here at a defined distance a of about 70 to 130 cm vertically above the lining 2 and consists of a screwed onto the end of a designated for feeding the transport medium 5 tube 13 holder 14, in the one with a nozzle 17th equipped insert 15 is inserted. The insert 15 has a mixing chamber 16, in the direction of flow of the transport medium inclined channels 18 for supplying the granules 6 into the mixing chamber 16 open. Furthermore, the mixing chamber 16 is followed by a focussing unit 19 formed by a tube piece, which is held by a screwed onto the holder 14 union nut 20. From the spray head 11 thus exits an initially focused spray jet 12, which fanned out after exiting the focusing unit 19.

Dem Sprühkopf 12 ist eine Ummantelung 21 zugeordnet, die durch ein geschlossenes, mit Abstand zu dem Belag 2 sowie dem Sprühstrahl 12 und parallel zu diesem angeordnetes Luftleitblech 22 gebildet ist. Auf diese Weise ist zwischen der Ummantelung 21 und dem Sprühstrahl 12 ein diesen umgebender Luftkanal 23 geschaffen, in dem Luftwirbel 24 entstehen.The spray head 12 is associated with a casing 21, which is formed by a closed, at a distance from the lining 2 and the spray jet 12 and parallel to this arranged air guide plate 22. In this way, a surrounding air duct 23 is created between the casing 21 and the spray jet 12, 24 arise in the air vortex.

Das Trägermedium strömt etwa mit 2- bis 3-facher Schallgeschwindigkeit und unter einem Druck von 1000 bis 7000 bar, vorzugsweise unter 3000 bar, in die Mischkammer 16 des Sprühkopfes 11 ein. Aufgrund der Injektorwirkung wird in der Mischkammer 16 das Granulat 6 in diese eingesaugt und das aus diesem und dem Trägermedium 5 gebildete Gemisch wird in der Fokussiereinheit 19 zu einem Sprühstrahl 12 gebündelt, der mit etwa 1- bis 2-facher Schallgeschwindigkeit aus der Fokussiereinheit 19 austritt. Bei Austritt aus dem Sprühkopf 11 wird der Sprühstrahl 12 aufgefächert. Durch die in dem Sprühstrahl 12 eingeschlossene und die diesen umgebende Luft wird sodann auf einer Diffusionsstrecke, die etwa 70 bis 80 % des Abstandes a entspricht, das Trägermedium verflüchtigt, so dass auf einer Wegstrecke von etwa 20 bis 30 % des Abstandes a das Granulat 6 von dem Trägermedium 5 getrennt ist. Das Aufschlagen des Granulates 6 auf den Belag 2 wird somit nicht durch das Trägermedium 5 beeinträchtigt, das Granulat 6 kann vielmehr, wie dies in Figur 2 gezeigt ist, in der Oberfläche 3 des Belages 2 eine Unzahl von Mikrokratern 4 ausbilden.The carrier medium flows approximately at 2 to 3 times the speed of sound and under a pressure of 1000 to 7000 bar, preferably below 3000 bar, in the mixing chamber 16 of the spray head 11 a. Due to the injector effect, the granulate 6 is sucked into the mixing chamber 16 and the mixture formed from this and the carrier medium 5 is concentrated in the focusing unit 19 to form a spray jet 12 which emerges from the focusing unit 19 at about 1 to 2 times the speed of sound , Upon exiting the spray head 11, the spray jet 12 is fanned out. By trapped in the spray 12 and the surrounding air is then volatilized on a diffusion path which corresponds to about 70 to 80% of the distance a, the carrier medium, so that over a distance of about 20 to 30% of the distance a, the granules. 6 is separated from the carrier medium 5. The impact of the granules 6 on the pad 2 is thus not affected by the support medium 5, the granules 6 may rather, as shown in Figure 2, in the surface 3 of the pad 2 form a myriad of microcraters 4.

Der Sprühkopf 11 bzw. der Sprühstrahl 12 kann gemäß Figur 3 bei ruhendem Belag 2 linear über diesem verfahren werden. Die Umkehrung der Bewegungsrichtung des Sprühkopfes 11 sollte hierbei seitlich neben dem Belag 2 erfolgen, auch sollte bei der Bearbeitung des Belages eine Überdeckung des Sprühstrahls 12 gegeben sein.The spray head 11 and the spray jet 12 can be moved in accordance with Figure 3 with resting pad 2 linearly over this. The reversal of the direction of movement of the spray head 11 should in this case take place laterally next to the lining 2, and should be given during the processing of the covering an overlap of the spray jet 12.

Bei einem in einer Transportrichtung T kontinuierlich bewegton, z.B. auf einer Palette 10 gelagerten Belag 2 z. Bsp. in Form von einzelnen Fliesen ist es angezeigt, den Sprühkopf 11 quer zu der Transportrichtung T zu verstellen oder pendeln zu lassen. Die Verstellbewegung des Sprühkopfes 11 sollte hierbei in Abhängigkeit von der Transportgeschwindigkeit der Palette 10 derart verlaufen und auf diese abgestellt sein, dass sich auf dem Belag 2 eine linienförmige achssenkrecht zu der Transportbewegung T verlaufende Bearbeitungsfläche ergibt. Die Bearbeitungsfläche ist in Figur 4 durch die mit F gekennzeichneten Pfeile, die Verstellbewegungen des Sprühkopfes 11 sind durch die mit St gekennzeichneten Pfeile schematisch dargestellt.In a continuously moving in a transport direction T, for example, mounted on a pallet 10 covering 2 z. Ex. In the form of individual tiles, it is appropriate to adjust the spray head 11 transversely to the transport direction T or to let oscillate. The adjustment movement of the spray head 11 should in this case be such in dependence on the transport speed of the pallet 10 and turned off on this, that results on the coating 2 a line-shaped achssenkrecht to the transport movement T extending processing surface. The processing surface is shown in Figure 4 by the Arrows marked F, the adjusting movements of the spray head 11 are shown schematically by the arrows marked with St.
