Description

Technisches GebietTechnical field

Die vorliegende Erfindung betrifft eine Schleifvorrichtung zur lösbaren Festlegung an einem Hakenteil eines Klettverschlusses des Hakenschlingentyps.The present invention relates to a grinding device for releasable attachment to a hook part of a hook and loop type hook and loop fastener.

Stand der TechnikState of the art

Schleifvorrichtungen mit entsprechenden Mitteln zur lösbaren Festlegung an einem Hakenteil sind aus dem Stand der Technik zahlreich bekannt. So offenbart beispielsweise die WO 2007/145435 A1 oder die EP 0 728 056 eine solche Vorrichtung.Grinding devices with corresponding means for releasable attachment to a hook part are known in large numbers from the prior art. For example, the WO 2007/145435 A1 or the EP 0 728 056 such a device.

Üblicherweise werden beispielsweise Schleifmaschinen oder Handgriffe mit entsprechenden Hakenteilen ausgestattet, an denen dann erfindungsgemäße bzw. vorbekannte Schleifvorrichtungen zur lösbaren Festlegung mit entsprechenden Schlingen festgelegt werden können. So kann bei Abnutzung der Schleifvorrichtung ein einfacher Austausch der Schleifvorrichtung erfolgen. Auch können bei verschiedenen Aufgaben verschiedene Schleifvorrichtung einfach gewechselt werden und später wieder verwendet werden. Dabei ist darauf zu achten, dass die Verbindung derart gestaltet ist, dass sie sich bei der Verwendung der Schleifvorrichtung nicht versehentlich ablöst, jedoch zum Auswechseln einfach ablösbar ist.Usually, for example, grinding machines or handles are equipped with corresponding hook parts, on which grinding devices according to the invention or previously known devices can then be fixed with suitable loops for releasable fixing. If the grinding device is worn, the grinding device can be replaced easily. Different grinding devices can also be easily changed for different tasks and used again later. It is important to ensure that the connection is designed in such a way that it does not accidentally detach when the grinding device is used, but is easily detachable for replacement.

Darüber hinaus besteht die Bestrebung, Rohstoffe einzusparen sowie die Produktion einfach und kostengünstig zu gestalten.In addition, efforts are being made to save raw materials and to make production simple and inexpensive.

Darstellung der ErfindungPresentation of the invention

Dementsprechend ist es Aufgabe der Erfindung vorbekannte Schleifvorrichtungen zur lösbaren Festlegung an einem Hakenteil eines Klettverschlusses des Hakenschlingentyps derart weiterzuentwickeln, dass Rohstoffe eingespart und die Herstellung vereinfacht werden kann.Accordingly, it is an object of the invention to further develop previously known grinding devices for releasable attachment to a hook part of a hook and loop fastener of the hook loop type in such a way that raw materials are saved and production can be simplified.

Gelöst wird die Aufgabe durch ein Schleifmittel nach Anspruch 1. Die abhängigen Ansprüche 2 bis 10 geben vorteilhafte Weiterbildungen an.The object is achieved by an abrasive according to claim 1. The dependent claims 2 to 10 indicate advantageous developments.

Die Anmelderin hat erkannt, dass im Stand der Technik entweder schwere Waren mit Flächengewichten von mehr als 75 g/m2 oder solche, die durch Aufrauen eines Textils Schlingen ausbilden, verwendet werden. D. h., bei Letztgenanntem sind die Schlingen nicht durch Weben, Stricken oder Wirken entstanden, sondern später durch eine entsprechende Aufrauhung hergestellt worden. Dies ist auch erforderlich, da ansonsten der Verbindungsvorgang mit weiteren Schichten, beispielsweise durch Klebemittel oder Kaschieren zu dem Problem führt, dass bei Verwendung anderer Waren z. B. Klebemittel durch die textile Lage derart hindurchtritt, dass die Schlingen nicht ihre Funktion auszuüben vermögen, zumindest nicht in dem vor der Verklebung möglichen Umfang oder der vor der Verklebung möglichen Stärke.The applicant has recognized that in the state of the art either heavy goods with a basis weight of more than 75 g / m 2 or goods which form loops by roughening a textile are used. In other words, in the latter case, the loops were not created by weaving, knitting or knitting, but were later made by roughening them accordingly. This is also necessary, since otherwise the connection process with further layers, for example by means of adhesive or lamination, leads to the problem that when using other goods, e.g. B. Adhesive passes through the textile layer in such a way that the loops are unable to perform their function, at least not to the extent possible before the gluing or the strength possible before the gluing.

Der Anmelderin war es jedoch möglich, textile Lagen zu entwickeln, die ein Flächengewicht von 75 g/m2 oder weniger aufweisen und dennoch ausreichend dicht sind, ein übermäßiges Durchtreten, beispielsweise vom Klebemittel, zu verhindern. Dies ist beispielsweise durch eine textile Lage möglich, die Garne beinhaltet, die in Fadenschlingen ausgebildet sind, die in sich longitudinal erstreckenden Rippen und sich transversal erstreckenden Reihen angeordnet sind und die wenigstens einen Satz von Grundgarnen beinhaltet, die in einem Maschenmuster von Fadenschlingen in beabstandeten Reihen und beabstandeten Rippen und in florartigen Schlingen kettengewirkt sind, die sich von der der Oberschicht der Schleifvorrichtung zugewandten Seite der textilen Lage nach der der Oberschicht der Schleifvorrichtung abgewandten Seite der textilen Lage erstrecken. Auch ist dies möglich durch textile Lagen, die Schlingen aufweisen, die aus Garnfäden Masche und Schlinge als Einheit dadurch ausbilden, dass in jeder fortlaufenden Masche in Längsrichtung sowie in Querrichtung gleichzeitig Schlingen vorliegen und eine Maschendichte im Bereich von 2.500 bis 7.500 Maschen/dm2 bei einer Maschenlänge im Bereich von 0,5 bis 2 mm aufweisen.However, the applicant was able to develop textile layers which have a weight per unit area of 75 g / m 2 or less and yet are sufficiently dense to prevent excessive penetration, for example of the adhesive. This is possible, for example, by means of a textile layer which includes yarns which are formed in thread loops, which are arranged in longitudinally extending ribs and transversely extending rows and which contains at least one set of base yarns which are in a stitch pattern of thread loops in spaced rows and spaced-apart ribs and warp knitted in pile-like loops which extend from the side of the textile layer facing the upper layer of the grinding device to the side of the textile layer facing away from the upper layer of the grinding device. This is also possible thanks to textile layers that have loops that form loops and loops as a unit from yarn threads in that there are loops in each continuous stitch in the longitudinal and transverse directions and a stitch density in the range from 2,500 to 7,500 stitches / dm 2 have a mesh length in the range of 0.5 to 2 mm.

Die Erfindung wird durch die Merkmalskombination des Anspruchs 1 definiert. Gemäß den abhängigen Ansprüchen werden weitere Ausführungsformen definiert.The invention is defined by the combination of features of claim 1. Further embodiments are defined according to the dependent claims.

Durch eine solche Schleifvorrichtung lassen sich die Rohstoffeinsätze insbesondere in Bezug auf die textile Lage reduzieren und kann dabei eine einfache Herstellung realisiert werden. Insbesondere ist ein Arbeitsgang der Aufrauhung nicht erforderlich.The use of raw materials, in particular with regard to the textile layer, can be reduced by such a grinding device and simple production can be realized in the process. In particular, a roughening operation is not necessary.

Darüber hinaus weisen die erfindungsgemäßen textilen Lagen, aufgrund der Ausbildung der Schlingen durch Wirken, Weben oder Stricken besonders zuverlässige Schlingen auf, die insbesondere in einem definierten Muster angeordnet sein können.In addition, due to the formation of the loops by knitting, weaving or knitting, the textile layers according to the invention have particularly reliable loops, which in particular can be arranged in a defined pattern.

Auch das Verbinden mit der Oberschicht kann auf einfache Weise durchgeführt werden. Dies kann beispielsweise mit Klebemitteln oder Kaschierung erfolgen. Die Oberschicht weist dabei selbst ein Trägermaterial auf, auf dem die Schleifmittel aufgebracht sind. Dann wird die Oberschicht in einer solchen Orientierung mit der textilen Lage, beispielsweise durch Verkleben verbunden, das Schleifmittel auf der von der textilen Lage abgewandten Seite des Trägermaterials vorhanden ist.The connection to the top layer can also be carried out in a simple manner. This can be done, for example, with adhesives or lamination. The top layer itself has a carrier material on which the abrasives are applied. Then the top layer is connected in such an orientation to the textile layer, for example by gluing, the abrasive is present on the side of the backing material facing away from the textile layer.

Alternativ ist es aber auch möglich, Schleifmittel, beispielsweise zusammen mit Klebemittel, auf die textile Lage aufzubringen. In beiden Alternativen ist die textile Lage zur Oberschicht so orientiert, dass sich die Schlingen von der Oberschicht weg erstrecken.Alternatively, however, it is also possible to apply abrasives, for example together with adhesives, to the textile layer. In both alternatives, the textile layer is oriented towards the upper layer so that the loops extend away from the upper layer.

Als Schleifmittel kommen verschiedene Schleifmittel infrage. Beispielsweise kann hier Korund, Siliciumcarbid, Bornitrid und/oder Diamant eingesetzt werden. In der Regel wird man hier entsprechende Körner aus dem zur Bildung des Schleifmittels eingesetzten Material verwenden und entsprechend einbetten oder auf einem Träger oder der textilen Lage fixieren. Als Mittel zur Befestigung des Schleifmittels, beispielsweise auf einer Trägerschicht oder direkt auf der textilen Lage können verschiedene Mittel, im Folgenden als Klebemittel bezeichnet, eingesetzt werden. Denkbar sind hier beispielsweise Harze, Gummi, Schelllack, Epoxidharze und/oder verschiedene Kunststoffe, beispielsweise Thermoplaste. Zwar ist es denkbar, auf die textile Lage auf der der Oberschicht zugewandten Seite zunächst eine Lage aus Harz oder anderem Klebemittel aufzutragen und sodann Schleifmittel aufzutragen und ggf. erneut eine Schicht Harz oder anderes Klebematerials aufzutragen. Dies kann ebenso auf einer Trägerschicht, beispielsweise aus Papier, erfolgen. Dann wird anschließend oder vorher die Trägerschicht auf die textile Lage aufgeklebt, aufkaschiert oder mit ihr verschweißt.Various abrasives can be used as abrasives. For example, corundum, silicon carbide, boron nitride and / or diamond can be used here. As a rule, appropriate grains of the material used to form the abrasive will be used and appropriately embedded or fixed on a carrier or the textile layer. Various means, hereinafter referred to as adhesives, can be used as means for fastening the abrasive, for example on a carrier layer or directly on the textile layer. be used. Resins, rubber, shellac, epoxy resins and / or various plastics, for example thermoplastics, are conceivable here. It is conceivable to first apply a layer of resin or other adhesive to the textile layer on the side facing the upper layer and then to apply abrasive and, if necessary, to apply a layer of resin or other adhesive material again. This can also be done on a carrier layer, for example made of paper. Then, or subsequently, the carrier layer is glued, laminated or welded to the textile layer.

Als Trägerschicht kommen hier Papiere, Gewebe oder Folien infrage.Papers, fabrics or foils can be used as carrier layers.

Erfindungsgemäß erfolgt eine flächige Verbindung zwischen Oberschicht und textiler Lage. Dies ist abzugrenzen von möglichen punktförmigen oder linienförmigen Verbindungen, die nicht flächendeckend sind. Als flächig ist dabei aber auch eine Verbindung zu verstehen, die beispielsweise aufgrund zahlreicher punktförmiger oder linienförmiger Verbindungen eine so große Fläche der Kontaktfläche zwischen Oberschicht und textiler Lage einnimmt, dass von einer flächigen Verbindung zu sprechen ist. Insbesondere ist dann von einer flächigen Verbindung zu sprechen, wenn 75 % oder mehr der Kontaktfläche eine Verklebung, Verschweißung und/oder Kaschierung aufweisen.According to the invention, there is a flat connection between the top layer and the textile layer. This must be differentiated from possible point-like or line-shaped connections that are not nationwide. However, a connection is also to be understood as being flat, which, for example due to numerous point-like or line-like connections, takes up such a large area of the contact area between the upper layer and the textile layer that one speaks of a flat connection. In particular, one speaks of a two-dimensional connection when 75% or more of the contact surface has an adhesive bond, weld and / or lamination.

In einer ersten bevorzugten Ausführungsart umfasst die Oberschicht eine Trägerschicht, die mit ihrer Unterseite mit der zur Oberschicht zugewandten Seite der textilen Lage durch Verklebung, Kaschierung oder Verschweißung flächig verbunden ist und auf ihrer Oberseite Schleifmittel aufweist. Als Trägerschicht kommt hier beispielsweise Papier infrage. Aber auch Gewebe oder Folie sind denkbar. Insbesondere weist die Trägerschicht eine geringere Flexibilität als die textile Lage auf. Dabei weisen insbesondere die neben Klebemittel und Schleifmittel in der Oberschicht als Trägerschicht umfassten Materialien, beispielsweise das verwendete Papier oder das Gewebe eine geringere Flexibilität als die textile Lage auf. Beispielsweise kann in einem ersten Arbeitsgang ein Schleifmittel auf die Oberseite der Trägerschicht aufgebracht werden und später die Trägerschicht mit ihrer Unterseite mit der textilen Lage verbunden werden. Aber auch ein umgekehrtes Vorgehen ist denkbar.In a first preferred embodiment, the top layer comprises a backing layer, the underside of which is connected flatly to the side of the textile layer facing the top layer by gluing, lamination or welding and has abrasives on its top. For example, paper can be used as the carrier layer. But fabric or foil are also conceivable. In particular, the backing layer has less flexibility than the textile layer. In particular, the materials included in the top layer in addition to adhesives and abrasives as the carrier layer, for example the paper or fabric used, are less flexible than the textile layer. For example, in a first step Abrasives are applied to the top of the backing layer and later the backing of the backing layer is connected to the textile layer. A reverse approach is also conceivable.

In einer zweiten besonders bevorzugten Ausgestaltung, bei der weiter Rohstoffe und Arbeitsgänge gespart werden können, wird die Oberschicht aus auf der zur Oberschicht gewandten Seite der textilen Lage angeordnetes Klebemittel und Schleifmittel gebildet. Dabei ist das Schleifmittel durch das Klebemittel mit der textilen Lage verbunden. Es kann sich hier um eine Verbindung dergestalt handeln, dass das Schleifmittel von Klebemittel unbedeckte Flächen aufweist, insbesondere nur teilweise in das Klebemittel hineinragt und insbesondere aus einer durch das Klebemittel gebildeten Ebene hervorsteht oder es kann sich um eine Einbettung handeln, bei der das Schleifmittel weitgehend oder vollständig von Klebemittel umgeben ist.In a second particularly preferred embodiment, in which further raw materials and operations can be saved, the top layer is formed from adhesive and abrasive arranged on the side of the textile layer facing the top layer. The abrasive is connected to the textile layer by the adhesive. This can be a connection in such a way that the abrasive has surfaces uncovered by the adhesive, in particular only partially protrudes into the adhesive and in particular protrudes from a plane formed by the adhesive, or it can be an embedding in which the abrasive largely or completely surrounded by adhesive.

In einer derartigen Ausgestaltung kann in einem Arbeitsgang beispielsweise eine erste Klebemittelschicht, insbesondere aus Harz, auf die textile Lage aufgebracht werden und sodann Schleifmittel auf dieses Harz aufgebracht werden und anschließend eine weitere Klebemittelschicht auf das Schleifmittel bzw. die erste Klebemittelschicht aufgebracht werden. Auf die zweite Klebemittelschicht kann ggf. auch verzichtet werden, wenn beispielsweise das Schleifmittel ausreichend tief in das Klebemittel eingebracht wird und das Klebemittel so gewählt ist, dass es sich über das eingebrachte Schleifmittel wieder schließt oder wenn auf eine Einbettung verzichtet werden soll.In such an embodiment, for example, a first adhesive layer, in particular made of resin, can be applied to the textile layer in one operation and then abrasive can be applied to this resin and then another adhesive layer can be applied to the abrasive or the first adhesive layer. The second layer of adhesive can optionally also be dispensed with if, for example, the abrasive is introduced sufficiently deep into the adhesive and the adhesive is selected such that it closes again via the introduced abrasive or if embedding is to be avoided.

Durch eine solche Ausgestaltung lassen sich zuverlässige Schlingen bei geringem Materialeinsatz und guter Verklebbarkeit bzw. Verschweißbarkeit oder Kaschierbarkeit der textilen Lage erreichen.With such a configuration, reliable loops can be achieved with little use of material and good adhesiveness or weldability or laminatability of the textile layer.

Besonders bevorzugt wird es bei dieser zweiten Art der Ausgestaltung der textilen Lage, Maschendichte im Bereich von 4.000 bis 6.000 Maschen/dm 2, optimalerweise im Bereich von 4.600 bis 5.000 Maschen/dm2 vorzusehen.In this second type of configuration of the textile layer, it is particularly preferred to provide mesh densities in the range from 4,000 to 6,000 meshes / dm 2 , optimally in the range from 4,600 to 5,000 meshes / dm 2 .
