Abstract
Description
Die Erfindung betrifft ein Schleifmittel mit einer Kontaktfläche zur Adaption mit einem Werkzeug.The invention relates to an abrasive with a contact surface for adaptation with a tool.
Schleifmittel der eingangs genannten Gattung bestehen in der Regel aus zumindest drei kombinatorisch miteinander verzahnten Elementen, nämlich einer Haftschicht, beispielsweise einer Klebeschicht oder einer Klettschicht, ferner einer Trägerschicht und der Schleifpartikelschicht.Abrasives of the type mentioned at the outset generally consist of at least three combinatorially interlocking elements, namely an adhesive layer, for example an adhesive layer or a Velcro layer, furthermore a backing layer and the abrasive particle layer.
So beschreibt beispielsweise das deutsche Gebrauchsmuster 94 07 622 einen Schleifkörper mit einer Kontaktfläche für die Adaption mit einem Werkzeug, beispielsweise mit einem Schleifklotz oder einer Schleifmaschine, wobei der Schleifkörper aus den Schleifpartikeln, also dem eigentlichen Schleifmittel, ferner einem schaum- oder schwammartigen Schleifmittelträger und einer Klettadaptionsfläche besteht und der schaum- oder schwammartige Schleifmittelträger als Reißhemmung des Schleifkörpers ausgebildet ist, die Schleifpartikel (d. h. das eigentliche Schleifmittel im schaum- oder schwammartigen Schleifmittelträger) eingebettet sind und aus diesem Haftbett herausragen, wobei ferner der schaum- oder schwammartige Schleifmittelträger zusammen mit der Schleifschicht und der Klettadaptionsfläche als biegsamer und windungsfähiger, flächiger Schleifkörper ausgebildet sind.For example, German utility model 94 07 622 describes an abrasive body with a contact surface for adaptation with a tool, for example with a sanding block or a grinding machine, the abrasive body consisting of the abrasive particles, i.e. the actual abrasive, also a foam or sponge-like abrasive carrier and one Velcro adaptation surface exists and the foam or sponge-like abrasive carrier is designed as an anti-tearing agent for the grinding body, the abrasive particles (ie the actual abrasive are embedded in the foam or sponge-like abrasive carrier) and protrude from this adhesive bed, the foam or sponge-like abrasive carrier together with the abrasive layer and the Velcro adaptation surface are designed as a flexible and windable, flat grinding body.
Der vorliegenden Erfindung liegt nun die überraschende Erkenntnis zugrunde, daß die Klettschicht gleichzeitig als Trägerschicht für die Schleifpartikel ausgebildet ist und als solche fungiert.The present invention is based on the surprising finding that the Velcro layer is simultaneously designed as a backing layer for the abrasive particles and functions as such.
Hierdurch wird ein extrem biegsames und windungsfähiges, flächiges Schleifmittel zur Adaption mit einem Werkzeug geschaffen, das ferner den sprunghaften Fortschritt mit sich bringt, ohne das Anbringen von Lochungen extrem durchsaugbar zu sein.This creates an extremely flexible and windable, flat abrasive for adaptation with a tool, which also brings about the rapid progress without being extremely suction-absorbent.
Diese Durchsaugbarkeit spielt in der praktischen Anwendung der gattungsmäßigen Schleifmittel bzw. Schleifkörper eine sehr wichtige Rolle.This suction capability plays a very important role in the practical application of the generic abrasives or abrasive media.
Bekanntlich hat sich in der Industrie, dem Handwerk und dem do-it-yourself-Bereich in den letzten Jahren das sogenannte Kletthaftsystem immer mehr durchgesetzt.As is well known, the so-called Velcro system has become more and more popular in industry, craft and do-it-yourself.
Unter dem Kletthaftsystem versteht man die Befestigung der Schleifkörper, beispielsweise der Schleifteller, der Schleifplatte und der Schleifmittelhalter, mittels einer Kletthaftverbindung am Werkzeugträger.The Velcro system means the attachment of the grinding media, for example the grinding plate, the grinding plate and the abrasive holder, by means of a Velcro connection to the tool carrier.
Bei dieser Art der Verbindung weist die Rückseite des Schleifwerkzeugs bzw. des Schleifmittels beispielsweise eine Kletthaftvelour-Schicht oder ein Polgewirke auf, während der Werkzeugträger einen Belag mit einer Vielzahl von pilz- oder auch hakenförmig ausgebildeten Klettelementen aufweist.With this type of connection, the back of the grinding tool or the abrasive has, for example, a Velcro-velor layer or a pile knit, while the tool carrier has a covering with a large number of mushroom-shaped or hook-shaped Velcro elements.
Das Kletthaftsystem wird heute bereits von nahezu allen Elektroschleifmaschinenherstellern propagiert und findet seine Anwendung beispielsweise beim Winkelschleifer, Exzenterschleifer, Schwingschleifer, bei Bandschleifsystemen und natürlich auch beim manuellen Schleifen.The Velcro system is already being propagated by almost all electric grinding machine manufacturers and is used, for example, in angle grinders, random orbital sanders, orbital sanders, in belt sanding systems and of course also in manual sanding.
Dieses Kletthaftsystem funktioniert naturgemäß nur dann, wenn die zum Einsatz kommenden Schleifwerkzeuge bzw. Schleifmittel, wie z. B. Schleifpapierscheiben oder Gewebeschleifscheiben bzw. deren Zuschnitte, einseitig mit einem Kletthaftvelour, einem Polgewirke oder einem analogen Gewebe, Gewirke, Gestricke oder Vlies beschichtet sind.This Velcro system naturally works only when the grinding tools or abrasives used, such as. B. abrasive paper discs or fabric grinding discs or their blanks, coated on one side with Velcro, a pile knitted fabric or an analog fabric, knitted fabric, knitted fabric or fleece.
Diese zusätzlich Ausrüstung ist für das Kletthaftsystem des Standes der Technik unbedingt erforderlich und verteuert in erheblichem Maß die entsprechenden Schleifwerkzeuge und Schleifmittel.This additional equipment is absolutely necessary for the Velcro adhesive system of the prior art and makes the corresponding grinding tools and abrasives considerably more expensive.
Der Erfindung liegt nun die Aufgabe zugrunde, Schleifmittel für das Kletthaftsystem zu schaffen, die nicht zusätzlich beispielsweise mit einem Kletthaftvelour oder einem Polgewirke beschichtet werden müssen.The invention is based on the object of creating abrasives for the Velcro adhesive system which do not have to be additionally coated, for example with a Velcro adhesive velor or a pile knit.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Unterlage für die Herstellung der Schleifmittel bzw. Schleifwerkzeuge kein Papier oder Gewebe verwendet wird, sondern ein klettfähiges Gewebe, Gewirke, Gestricke oder ein klettfähiges Vlies.The object is achieved in that no paper or fabric is used as a base for the manufacture of the abrasives or grinding tools, but rather a Velcro-capable fabric, knitted fabric, knitted fabric or a Velcro-capable fleece.
Dabei erfüllt also diese klettfähige Schicht, vorzugsweise Textilschicht, gleichzeitig die Funktion der Trägerschicht für die Schleifpartikelchen.This hook-and-loop layer, preferably a textile layer, simultaneously fulfills the function of the carrier layer for the abrasive particles.
Als Schleifpartikelchen kommen insbesondere Aluminiumoxid, vorzugsweise Korund, Siliciumcarbid, Flint, Quarzsand und Polierkreide infrage.Particularly suitable grinding particles are aluminum oxide, preferably corundum, silicon carbide, flint, quartz sand and polishing chalk.
Die Gewebeschicht besteht beispielsweise aus einer Kletthaftvelourschicht, die aus Polyamid gebildet sein kann.The fabric layer consists, for example, of a Velcro Velcro layer, which can be formed from polyamide.
Das Polgewirke besteht vorzugsweise aus reißfesten und temperaturbeständigen Schlingen. Erfindungsgemäß können die Material- und Herstellkosten im Vergleich zu den Schleifkörpern, Schleifwerkzeugen bzw. Schleifmitteln des Standes der Technik erheblich reduziert werden, wobei auch zusätzlich die Kosten für das Aufbringen, beispielsweise des Kletthaftvelours auf das Schleifmittel, entfallen.The pile knit preferably consists of tear-resistant and temperature-resistant loops. According to the invention, the material and manufacturing costs can be considerably reduced in comparison to the grinding bodies, grinding tools or abrasives of the prior art, the costs for the application, for example of the velcro velor, to the abrasive also being eliminated.
Die Kletthaftgewebeschichten und die genannten analogen Ausführungsformen, beispielsweise das Kletthaftvelourgewebe, die erfindungsgemäß Schleifpartikelträger (= Schleifkornträger) sind, sind derart beschaffen, daß durch das Gewebe hindurch der Schleifstaub abgesaugt werden kann. Dies hat den weiteren Vorteil, daß das bisher notwendige, zusätzliche Lochen der Schleifmittel für die mit einer Absaugevorrichtung versehenen Elektromaschinen entfällt, was eine weitere Kosteneinsparung mit sich bringt und auch die Lagerhaltung vereinfacht, da das erfindungsgemäße Schleifmittel über die gesamte Schleiffläche den feinen Schleifstaub hindurchläßt und somit für alle gängigen Elektromaschinen mit Absaugung geeignet ist.The velcro adhesive layers and the mentioned analog embodiments, for example the velcro velor fabric, which according to the invention are abrasive particle carriers (= abrasive grain carriers), are designed in such a way that the grinding dust can be extracted through the tissue. This has the further advantage that the additional punching of the abrasive for the electric machines provided with a suction device, which was previously necessary, is no longer required, which brings further cost savings and also simplifies storage, since the abrasive according to the invention allows the fine grinding dust to pass through and over the entire grinding surface is therefore suitable for all common electrical machines with suction.
Bis jetzt war es notwendig, daß nahezu jeder Elektromaschinenhersteller seine eigene Lochung hatte bzw. vorgeschrieben hat, was nachteiligerweise dazu führte, daß z. B. der Schleifmittelhandel einen Schleifmittelzuschnitt in einer Körnung z. B. in drei bis vier verschiedenen Lochungen bevorraten mußte, um die gängigsten Maschinentypen abdecken zu können.Until now, it was necessary for almost every electrical machine manufacturer to have or have prescribed its own perforation, which disadvantageously led to the fact that e.g. B. the abrasives trade an abrasive blank in a grain z. B. had to stock up in three to four different perforations to cover the most common types of machines.
Dies bedeutet erhebliche Lagerhaltungskosten und Kapitalbindung.This means considerable storage costs and capital commitment.
Die erfindungsgemäßen Schleifmittel, also beispielsweise die auf einem Kletthaftvelourgewebe oder Polgewirke aufgebauten Schleifmittel, sind sowohl für den Naß- als auch für den Trockenschliff geeignet. Auch diese doppelte Nutzung bringt gegenüber den bisherigen Schleifpapieren Kostenvorteile.The abrasives according to the invention, that is to say, for example, the abrasives built up on a velcro or pile fabric, are suitable for both wet and dry sanding. This double use also brings cost advantages over the previous abrasive papers.
Ein weiterer Vorteil, der bereits weiter oben genannt wurde, nämlich die fortschrittliche Eigenschaft der erfindungsgemäßen Schleifmittel, beispielsweise der erfindungsgemäß vorhandenen Kletthaftvelourgewebe oder Polgewirke besteht darin, daß sie als Schleifpartikelträger (= Schleifkornträger) auch im gröberen Kornbereich flexibler und anpassungsfähiger sind als die Schleifkörper bzw. Schleifmittel des Standes der Technik.Another advantage, which has already been mentioned above, namely the progressive property of the abrasives according to the invention, for example the Velcro velor fabrics or pile fabrics present according to the invention, is that, as abrasive particle carriers (= abrasive grain carriers), they are more flexible and adaptable even in the coarser grain area than the abrasive bodies or State of the art abrasives.
