Abstract

The adhesive closing part has a functional layer, which defines a carrier surface (8) and is formed of a fiber system with two line elements (12a-12c,14a,14b) that are connected with each other and form a mesh. Another functional layer has individually formed connecting elements (30,30'). The fiber systems are connected with each other by forming passage points (24a-24d), whose open cross section area is more than 20 percent of the corresponding carrier surface. An independent claim is also included for a method for manufacturing an adhesive closing part.

Description

Die Erfindung betrifft ein Haftverschlussteil umfassend eine eine Trägerfläche festlegende Funktionslage, gebildet aus einem Fadensystem mit mindestens zwei miteinander verbundenen und Maschen bildenden Linienelementen, mindestens eine einzelne gebildete und/oder bildbare Verbindungselemente aufweisende weitere Funktionslage, gebildet aus einem zumindest bereichsweise in das Fadensystem eingebundenen Fadensystem.The invention relates to an adhesive closure part comprising a functional layer defining a carrier surface, formed from a thread system with at least two interconnected and mesh forming line elements, at least one individual formed and / or formable connecting elements having further functional position, formed from an at least partially integrated into the thread system thread system.

Derartige Haftverschlussteile werden in unterschiedlichsten Bereichen insbesondere in Befestigungssystemen, beispielsweise an Kleidungsstücken, Gepäckstücken, Möbelstücken, Verkleidungen im Fahrzeuginnenraum usw. eingesetzt und sind dementsprechend in unterschiedlichsten Ausführungen bekannt. Typischerweise ist das Haftverschlussteil ein textiler Flächenhaftverschluss mit pilzförmigen Verhakungselementen und in der Regel aus einem Kunststoffmaterial gefertigt. An einer den Verbindungselementen abgewandten Rückseite kann das Haftverschlussteil eine Beschichtung, beispielsweise eine Klebeschicht, aufweisen.Such adhesive closure parts are used in a wide variety of areas, in particular in fastening systems, for example on garments, pieces of luggage, pieces of furniture, panels in the vehicle interior, etc., and are therefore known in a wide variety of designs. Typically, the adhesive closure part is a textile surface fastener with mushroom-shaped interlocking elements and usually made of a plastic material. On a rear side facing away from the connecting elements, the adhesive closure part may have a coating, for example an adhesive layer.

Eine weitere Anwendung eines Haftverschlussteils ist die Verbindung bzw. Befestigung eines Schleifkörpers an einem Schleifmittelhalter. Aus EP 0 781 629 B1 ist ein Schleifkörper, bestehend aus einer ein Schleifmittel aufweisenden, partikelstromundurchlässigen Schicht bekannt, welcher direkt oder über einen Adapter indirekt auf einem Schleifmittelhalter arbeitsgerecht befestigbar ist, mit Durchbrechungen, die zumindest die das Schleifmittel aufweisende Schicht durchdringen, und einer Klettadaptionsschicht, die gas- und partikelstromdurchlässig ausgebildet ist. Die Durchbrechungen sind als gas- und partikeldurchströmbare Perforation ausgebildet, die annähernd gleichmäßig über die gesamte Fläche des Schleifkörpers oder eines Teils davon verteilt ist, wobei die einzelnen, die Perforation bildenden Durchbrechungen miteinander in Verbindung stehen und deren Abstand zueinander so gewählt ist, dass ein nahezu stauloser kontinuierlicher Abtransport des Schleifstaubes ermöglicht ist.Another application of an adhesive closure member is the attachment of an abrasive article to an abrasive article holder. Out EP 0 781 629 B1 is an abrasive body consisting of an abrasive having, particle-current impermeable layer known which directly or indirectly via an adapter on an abrasive holder work can be fastened, with openings, which penetrate at least the layer having the abrasive, and a Velcro adaptation layer, which is formed gas and particle flow permeable. The apertures are formed as a gas and particle-perforated perforation which is distributed approximately uniformly over the entire surface of the grinding wheel or a part thereof, wherein the individual, the perforations forming apertures communicate with each other and whose distance from each other is chosen so that a nearly stauloser continuous removal of the grinding dust is possible.

Ein hierbei eingesetzter Adapter besteht aus einer Klettadaptionsschicht, einer Schaumpartikelschicht und einer Veloursschicht, wobei die zum Schleifkörper hin weisende Klettadaptionsschicht von der Perforation durchdrungen ist. Eine typischerweise kreisrunde Schleifscheibe weist auf ihrer Rückseite ein Velours zum Ankletten an die Schleifplatte auf. Durch die entsprechende Anordnung der Durchbrechung der Perforation zueinander sowie gegenüber den Absaugeinrichtungen des Schleiftellers ist ein nahezu stauloser Transport des Schleifstaubes zu den Absaugeinrichtungen bewirkt.An adapter used in this case consists of a Velcro adaptation layer, a foam particle layer and a velor layer, wherein the Velcro adaptation layer facing the abrasive body is penetrated by the perforation. A typical circular grinding wheel has on its back a velor for Ankletten to the grinding plate. By the appropriate arrangement of the perforation of the perforation to each other and with respect to the suction of the sanding plate a nearly stauzy transport of the grinding dust is effected to the suction devices.

Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Aufgabe, ein Haftverschlussteil bereitzustellen, welches einen einfachen Aufbau aufweist, insbesondere in einfacher Weise herstellbar ist, und zur Befestigung eines Schleifkörpers an einem Schleifmittelhalter eingesetzt werden kann, ohne den Schleifvorgang zu behindern.Starting from this prior art, the invention has the object to provide an adhesive closure part, which has a simple construction, in particular can be produced in a simple manner, and can be used to attach an abrasive article to an abrasive holder, without hindering the grinding process.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Haftverschlussteil mit den Merkmalen des Patenanspruchs 1 in seiner Gesamtheit. Dadurch, dass die Fadensysteme unter Bildung von Durchlassstellen miteinander verbunden sind, deren freie Querschnittsfläche mehr als 20% der entsprechenden Trägerfläche einnimmt, kann an der Anlage- bzw. Befestigungsfläche der vom Schleifkörper abgesaugte Schleifstaub durch das Haftverschlussteil weitestgehend ungehindert hindurchtreten. Das erfindungsgemäße Haftverschlussteil bietet insbesondere den Vorteil, dass bei Befestigung eines Schleifkörpers am Schleifmittelhalter keine besondere Ausrichtung des Haftverschlussteils in Bezug auf den Schleifkörper bzw. den Schleifmittelhalter gewählt werden muss, da das Haftverschlussteil über seine gesamte Fläche, genauer im Bereich der weiteren Funktionslage, staubdurchlässig ausgebildet ist.This object is achieved by an adhesive fastener with the features of claim 1 in its entirety. The fact that the thread systems are connected to form passage points whose free cross-sectional area occupies more than 20% of the corresponding support surface, can at the investment or mounting surface the abrasive dust extracted by the abrasive body passes through the adhesive closure part largely unhindered. In particular, the adhesive closure part according to the invention offers the advantage that when attaching an abrasive article to the abrasive article holder, no special alignment of the adhesive closure element with respect to the abrasive article or abrasive article holder has to be selected since the adhesive closure element is dust-permeable over its entire surface, more precisely in the region of the further functional layer is.

Der Einsatz des erfindungsgemäßen Haftverschlussteils beschränkt sich nicht auf den Bereich von Schleifkörpern, sondern erstreckt sich auf jeden Bereich, in welchem ein Fluiddurchtritt an einer Befestigungsfläche erwünscht und/oder zwingend ist. Vorstellbar ist beispielsweise die Befestigung eines zur Abwasser- oder Abluftreinigung eingesetzten Siebes in einem fluiddurchströmten Bereich oder eines in einer hydraulischen Anlage eingesetzten Filterelements. Auch ein Einsatz im Bereich atmungsaktiver Textilien, welche unter anderem im medizinischen oder pflegerischen Bereich eingesetzt werden, ist denkbar.The use of the adhesive closure part according to the invention is not restricted to the area of abrasive bodies, but extends to any area in which a fluid passage on a fastening surface is desired and / or compulsory. It is conceivable, for example, the attachment of a sieve used for sewage or exhaust air purification in a fluid-flow area or a filter element used in a hydraulic system. A use in the field of breathable textiles, which are used, inter alia, in the medical or nursing area, is conceivable.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlussteils umfasst zumindest ein eine Funktionslage bildendes Fadensystem eine Reihenanordnung von mindestens zwei in eine Längsrichtung verlaufenden, zueinander benachbarten Linienelementen, wobei die Linienelemente jeweils eine Folge von im Wesentlichen gleichartigen, in eine Querrichtung gerichteten Maschen bilden und in Längsrichtung versatzfrei zueinander angeordnet sind, und wobei eine oder mehrere Maschen zumindest eines Linienelements die entsprechenden Maschen des jeweils benachbarten Linienelements durch- bzw. umgreifen und somit miteinander verbinden. Hieraus ergibt sich der Vorteil eines formstabilen, in einfacher Weise herzustellenden Haftverschlussteils und insbesondere eine stabile, belastbare Trägerfläche. Die Maschen der einzelnen Linienelemente können mäanderförmig ausgebildet sein und jeweils eine rechteckförmige Kontur aufweisen. Alternativ können die Maschen schlaufen- bzw. schlingenartig ausgebildet sein und eine ellipsen- bzw. kreisförmige Kontur aufweisen.In a preferred embodiment of the adhesive closure part according to the invention, at least one thread system forming a functional layer comprises a series arrangement of at least two line elements extending in a longitudinal direction, wherein the line elements each form a sequence of substantially similar meshes oriented in a transverse direction and mutually offset in the longitudinal direction are arranged, and wherein one or more stitches at least one line element, the respective meshes of the respective adjacent line element by or surround and thus connect to each other. This results in the advantage of a dimensionally stable, easy to produce adhesive closure part and in particular a stable, load-bearing surface. The meshes of the individual line elements may be formed meander-shaped and each having a rectangular contour. Alternatively, the stitches may be loop-shaped or loop-shaped and have an elliptical or circular contour.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlussteils umfasst das die weitere Funktionslage bildende Fadensystem mindestens ein in Längsrichtung verlaufendes Linienelement mit einer Folge von im Wesentlichen gleichartigen, in Querrichtung gerichteten Maschen, welche zumindest teilweise zur Bildung von Verbindungselementen auftrennbar und/oder aufgetrennt sind. Besonders bevorzugt verläuft das mindestens eine Linienelement der weiteren Funktionslage entlang eines entsprechenden Linienelements in der Trägerfläche und ist in entsprechender Weise mit (einem) benachbarten Linienelementen verbunden. Auf diese Weise kann das die weitere Funktionslage, typischerweise eine Verbindungslage, ausbildende weitere Fadensystem in einfacher Weise in das die Trägerlage bildende Fadensystem eingebunden werden. Ein dementsprechend gestaltetes Herstellungsverfahren lässt sich in einfacher Weise durchführen, insbesondere mit einer zur Bildung des Fadensystems geeigneten Webe- oder Wirkvorrichtung.In a further preferred embodiment of the adhesive closure part according to the invention, the thread system forming the further functional layer comprises at least one line element extending in the longitudinal direction with a series of substantially similar, transversely oriented stitches which are at least partially separable and / or split to form connecting elements. Particularly preferably, the at least one line element of the further functional layer runs along a corresponding line element in the carrier surface and is connected in a corresponding manner to (an) adjacent line elements. In this way, the further functional position, typically a connecting layer, forming further thread system can be integrated in a simple manner into the thread system forming the carrier layer. A correspondingly designed production method can be carried out in a simple manner, in particular with a weaving or knitting device suitable for the formation of the thread system.

Zweckmäßigerweise weisen die Maschen benachbarter Linienelemente in Längsrichtung die gleiche Erstreckung und/oder Reihenfolge auf. Auf diese Weise wird ein besonders sicherer und lagefester Verbund zwischen den Linienelementen geschaffen. Bevorzugterweise weist das die Trägerfläche bildende Fadensystem eine Reihenanordnung von sich abwechselnden ersten und zweiten Linienelementen auf, wobei die ersten Maschen der ersten Linienelemente in Querrichtung eine größere Erstreckung als die zweiten Maschen der zweiten Linienelemente aufweisen. In dieser Ausgestaltung des Haftverschlussteils entstehen vergleichsweise feste Verbindungsstellen an den Kreuzungsstellen zwischen Maschen benachbarter Linienelemente, wodurch die Maschenanordnung weitestgehend lagefixiert wird.Conveniently, the meshes of adjacent line elements in the longitudinal direction of the same extent and / or order. In this way, a particularly secure and stable connection between the line elements is created. Preferably, the thread system forming the carrier surface has a series arrangement of alternating first and second line elements, wherein the first stitches of the first line elements in the transverse direction have a greater extent than the second stitches of the second line elements. In this embodiment of the adhesive closure part, comparatively firm connection points arise at the intersections between meshes of adjacent line elements, whereby the mesh arrangement is largely fixed in position.

In einer bevorzugten Ausgestaltung weist das erfindungsgemäße Haftverschlussteil ein sich in Quer- und/oder Längsrichtung in regelmäßigen Abständen wiederholendes Muster mit im Wesentlichen gleichartig ausgebildeten und/oder angeordneten Linienelementen der Fadensysteme auf. Hieraus ergibt sich der Vorteil eines über die Funktionslagen bzw. die Trägerfläche homogenen Aufbaus und folglich homogener Eigenschaften des Haftverschlussteils, wie Formstabilität, Elastizität, Fluiddurchlässigkeit.In a preferred embodiment, the adhesive closure part according to the invention has a pattern which repeats in the transverse and / or longitudinal direction at regular intervals and has substantially identically constructed and / or arranged line elements of the thread systems. This results in the advantage of a homogeneous structure over the functional layers or the support surface and consequently homogeneous properties of the adhesive closure part, such as dimensional stability, elasticity, fluid permeability.

Zweckmäßigerweise ist die Funktionslage über die gesamte Trägerfläche mit dem weiteren Fadensystem verbunden, mit anderen Worten das Haftverschlussteil vollflächig in der erfindungsgemäßen Weise ausgebildet. Eine elastische bzw. flexible Ausgestaltung des Haftverschlussteils erlaubt dessen Anbringung als Dekorflächengebilde auf mitunter komplizierten 3D-Konturen zu deren Abdeckung. Das erfindungsgemäße Haftverschlussteil ist ein besonders weiches, dehnfähiges, offenporiges Flächengebilde. Die von dem Haftverschlussteil freigegebenen Durchlassöffnungen können parallelogrammartig, insbesondere rautenförmig oder rechteckförmig, und/oder polygonförmig, insbesondere hexagonförmig, ausgebildet sein. Auf diese Weise kann ein stabiler Funktionslagenverbund bei einer ausreichenden Formstabilität und Fluiddurchlässigkeit des Haftverschlussteils gewährleistet werden.Expediently, the functional layer is connected over the entire carrier surface with the further thread system, in other words the adhesive closure part is formed over its entire surface in the manner according to the invention. An elastic or flexible embodiment of the adhesive closure part allows its attachment as a decorative surface on sometimes complicated 3D contours to the cover. The adhesive closure part according to the invention is a particularly soft, extensible, open-pored fabric. The passage openings released by the adhesive closure part may be parallelogram-like, in particular diamond-shaped or rectangular, and / or polygonal-shaped, in particular hexagonal-shaped. In this way, a stable functional layer composite can be ensured with sufficient dimensional stability and fluid permeability of the adhesive closure part.

Vorteilhafterweise besteht das erfindungsgemäße Haftverschlussteil aus einem bevorzugt thermoplastischen Kunststoffmaterial, insbesondere Polyamid und bevorzugt isotaktischem Polypropylen. Besonders bevorzugt ist das Kunststoffmaterial recycelbar. Isotaktisches Polypropylen ist zur Ausbildung von Verhakungselementen mit Pilzköpfen besonders gut geeignet. Die Linienelemente der Fadensysteme sind typischerweise als Monofilamente, Multifilamente und/oder Garne ausgebildet. Diese können entsprechend einer gewünschten Anwendung eingefärbt sein.Advantageously, the adhesive closure part according to the invention consists of a preferably thermoplastic plastic material, in particular polyamide and preferably isotactic polypropylene. Particularly preferably, the plastic material is recyclable. Isotactic polypropylene is particularly well-suited for the formation of hooking elements with mushroom heads. The line elements of the thread systems are typically monofilaments, Multifilaments and / or yarns formed. These can be colored according to a desired application.

Die Verbindungselemente des erfindungsgemäßen Haftverschlussteils sind typischerweise pilzartig ausgebildet und weisen Verhakungsköpfe auf. Weiter ist es vorteilhaft, die Verbindungselemente auf einer Seite des Haftverschlussteils auszubilden. Somit steht eine von Verbindungselementen freie Rückseite des Haftverschlussteils als Verbindungsfläche mit einem Bauteil, wie einem Schleifmittelhalter, zur Verfügung. Bevorzugterweise wird dort eine Klebefläche aufgebracht. Es ist jedoch auch denkbar, an beiden Seiten, d.h., an Ober- und Unterseite des Haftverschlussteils jeweils eine weitere Funktionslage mit Verbindungselementen vorzusehen.The connecting elements of the adhesive closure part according to the invention are typically mushroom-shaped and have hooking heads. Further, it is advantageous to form the connecting elements on one side of the adhesive closure part. Thus, a connector-free rear side of the adhesive closure part is available as a connection surface with a component, such as an abrasive holder. Preferably, an adhesive surface is applied there. However, it is also conceivable to provide a further functional layer with connecting elements on both sides, that is to say on the upper and lower sides of the adhesive closure part.

Fig. 1 zeigt eine Funktionslage 2, welche eine sich in eine Längsrichtung 4 und in eine Querrichtung 6 erstreckende Trägerfläche 8 festlegt. In der Ebene der Trägerfläche 8 ist ein Fadensystem 10 angeordnet, welches erste Linienelemente 12a, 12b, 12c, 12d und zweite Linienelemente 14a, 14b, 14c umfasst. Die ersten und zweiten Linienelemente 12a bis 12d, 14a bis 14c sind im Wesentlichen parallel zueinander in Längsrichtung 4 verlaufend angeordnet (Folge 12a, 14a, 12b, 14b, 12c, 14c, 12d). Die ersten Linienelemente 12a bis 12d sind derart im Fadensystem 10 angeordnet, dass sie jeweils eine Folge bzw. Aneinanderreihung von ersten Maschen 16a, 16a', 16a" des ersten Linienelements 12a, erste Maschen 16b, 16b', 16b" des ersten Linienelements 12b, usw. ausbilden. Die ersten Maschen 16a, 16a', 16a" sind im Wesentlichen gleichartig ausgebildet und erstrecken sich jeweils in Querrichtung 6. Wie durch eine Linie 18 für das erste Linienelement 12a angedeutet, verlaufen die ersten Maschen 16a bis 16a" von der Line 18 in Querrichtung 6 und wieder zurück zur Linie 18, wobei eine rechteckförmige Kontur festgelegt bzw. ein rechteckförmiger Verlauf durch die jeweilige erste Masche 16a bis 16a" teilweise durchlaufen wird. Die ersten Linienelemente 12a bis 12d sind in Längsrichtung 4 ohne Versatz angeordnet, so dass sich in Querrichtung 6 an die erste Masche 16a des ersten Linienelements 12a die erste Masche 16b des benachbarten ersten Linienelements 12b anschließt. Fig. 1 shows a functional layer 2, which defines a in a longitudinal direction 4 and in a transverse direction 6 extending support surface 8. In the plane of the support surface 8, a thread system 10 is arranged, which comprises first line elements 12a, 12b, 12c, 12d and second line elements 14a, 14b, 14c. The first and second line elements 12a to 12d, 14a to 14c are arranged substantially parallel to one another in the longitudinal direction 4 (sequence 12a, 14a, 12b, 14b, 12c, 14c, 12d). The first line elements 12a to 12d are arranged in the thread system 10 such that they each have a sequence of first stitches 16a, 16a ', 16a "of the first line element 12a, first stitches 16b, 16b', 16b" of the first line element 12b, etc. train. The first stitches 16a, 16a ', 16a "are of substantially similar construction and each extend in the transverse direction 6. As indicated by a line 18 for the first line element 12a, the first stitches 16a to 16a" extend from the line 18 in the transverse direction 6 and again back to the line 18, whereby a rectangular contour is defined or a rectangular course through the respective first stitch 16a to 16a "is partially passed through. The first line elements 12a to 12d are arranged without offset in the longitudinal direction 4, so that in the transverse direction 6 the first loop 16a of the first line element 12a is followed by the first loop 16b of the adjacent first line element 12b.

Die zweiten Linienelemente 14a bis 14c weisen jeweils eine Aufeinanderfolge von zweiten Maschen 20a, 20a', 20a" des zweiten Linienelements 14a, zweite Maschen 20b, 20b', 20b" des zweiten Linienelements 14b, usw. auf. Die zweiten Maschen 20a bis 20b" sind jeweils gleichartig ausgebildet und, da die zweiten Linienelemente 14a bis 14c ohne Versatz in Längsrichtung 4 zueinander angeordnet sind, in Querrichtung 6 zueinander unmittelbar aufeinander folgend angeordnet. Die Verbindung bzw. Verwebung der ersten und zweiten Linienelemente 12a bis 12d, 14a bis 14c wird am Beispiel der zweiten Masche 20a näher erläutert: Die zweite Masche 20a durchgreift die erste Masche 16a des ersten Linienelements 12a und ist um die erste Masche 16b des benachbarten Linienelements 12b geführt, anders ausgedrückt ist die erste Masche 16b durch die zweite Masche 20a des zweiten Linienelements 14a durchgeführt. Durch die erste Masche 20a werden an zwei Verbindungsstellen 22a, 22b die benachbarten ersten Linienelemente 12a, 12b aneinander gebunden und in ihrer jeweiligen Lage stabilisiert. Zur Ausbildung entsprechend fester Verbindungsstellen 22a, 22b ist die Erstreckung der zweiten Masche 20a in Querrichtung 6 geringer als die entsprechende Erstreckung der ersten Maschen 16a und 16b.The second line elements 14a to 14c each have a succession of second stitches 20a, 20a ', 20a "of the second line element 14a, second stitches 20b, 20b', 20b" of the second line element 14b, and so on. The second meshes 20a to 20b "are each of identical design and, since the second line elements 14a to 14c are arranged without offset in the longitudinal direction 4 relative to one another, are arranged directly following one another in the transverse direction 6. The connection or interweaving of the first and second line elements 12a to The second loop 20a extends through the first loop 16a of the first line element 12a and is guided around the first loop 16b of the adjacent line element 12b; in other words, the first loop 16b passes through the first loop 16b The first loop 20a at two connecting points 22a, 22b binds and stabilizes the adjacent first line elements 12a, 12b in their respective positions Mesh 20a in the transverse direction 6 lower a ls the corresponding extension of the first stitches 16a and 16b.

Die ersten Linienelemente 12a bis 12d sind jeweils aus einem Monofilament, die zweiten Linienelemente 14a bis 14d jeweils aus einem Multifilament gebildet. Die Fadendicke und die Maschenweite der ersten und zweiten Linienelemente 12a bis 12d, 14a bis 14c ist derart gewählt, dass freie Durchlassstellen 24a, 24b, 24c zwischen den ersten und zweiten Linienelementen 12a bis 12d, 14a bis 14c entstehen, wodurch das Fadensystem 10 bzw. die Funktionslage 2 fluiddurchlässig ist. Die freien Durchlass- bzw. Querschnittsflächen der Durchlassstellen 24a bis 24c stellen weit über 20% der Trägerfläche 8 dar bzw. nehmen diese ein.The first line elements 12a to 12d are each formed from a monofilament, the second line elements 14a to 14d each formed from a multifilament. The thread thickness and the mesh width of the first and second line elements 12a to 12d, 14a to 14c is selected such that free passage points 24a, 24b, 24c arise between the first and second line elements 12a to 12d, 14a to 14c, whereby the thread system 10 or the functional layer 2 is fluid-permeable. The free passage or cross-sectional areas of the passages 24a to 24c represent well over 20% of the support surface 8 or occupy this.

In Fig. 2 ist dargestellt, wie in das Fadensystem 10 aus Fig. 1 ein weiteres Fadensystem aus dritten Linienelementen 26a, 26b, 26c eingebunden bzw. eingewoben ist. Die dritten Linienelemente 26a bis 26c folgen jeweils dem Verlauf eines ersten Linienelements 12a, 12b, 12c und sind über zweite Linienelemente 14a, 14b miteinander verbunden. Entsprechend den ersten Linienelementen 12a bis 12c weisen die dritten Linienelemente 26a bis 26c, dritte Maschen 28a, 28a' auf, welche jeweils dem Verlauf einer ersten Maschen 16a, 16a' folgen und im regelmäßigen Abstand von zwei Maschen 28a bzw. 16a zur Bildung von jeweils zwei sich zur (nicht gezeigten) Oberseite erstreckenden Verbindungselementen 30, 30' aufgetrennt sind.In Fig. 2 is shown as in the thread system 10 from Fig. 1 another thread system of third line elements 26a, 26b, 26c integrated or is woven. The third line elements 26a to 26c each follow the course of a first line element 12a, 12b, 12c and are connected to each other via second line elements 14a, 14b. Corresponding to the first line elements 12a to 12c, the third line elements 26a to 26c have third stitches 28a, 28a 'which respectively follow the course of a first stitch 16a, 16a' and at regular intervals of two stitches 28a and 16a, respectively two connecting elements 30, 30 'extending to the upper side (not shown) are separated.

In den Fig. 3 und 4 ist die regelmäßige Anordnung der Linienelemente 12a bis 12d, 14a bis 14d, 26a bis 26c und die sich daraus ergebende Ausbildung eines Musters dargestellt. Die ersten Linienelemente 12a, 12b, 12c und die zweiten Linienelemente 14a, 14b bilden erste Maschen 16a, 16a', 16a" bzw. zweite Maschen (nicht bezeichnet), welche sowohl in Längsrichtung 4 als auch in Querrichtung 6 regelmäßig nach- und zueinander angeordnet sind. Die dem Verlauf der ersten Linienelemente 12a bis 12c folgenden dritten Linienelemente 26a bis 26c sind sowohl in Längsrichtung 4 als auch in Querrichtung 6 an jeder zweiten der dritten Maschen (nicht bezeichnet) zur Bildung von Verbindungselementen 30, 30' aufgetrennt.In the Fig. 3 and 4 the regular arrangement of the line elements 12a to 12d, 14a to 14d, 26a to 26c and the consequent formation of a pattern is shown. The first line elements 12a, 12b, 12c and the second line elements 14a, 14b form first stitches 16a, 16a ', 16a "and second stitches (not labeled), which are arranged in the longitudinal direction 4 as well as in the transverse direction 6 regularly The third line elements 26a to 26c following the course of the first line elements 12a to 12c are separated both longitudinally 4 and transversely 6 at every other of the third stitches (not labeled) to form connecting elements 30, 30 '.

Im gezeigten und beschriebenen Ausführungsbeispiel sind die dritten Linienelemente 26a bis 26c in Längs- und Querrichtung 4, 6 betrachtet an jeder zweiten dritten Masche zu Verbindungselementen aufgetrennt, so dass sich an diesen Stellen größere Durchlassstellen 24a im Vergleich zu Durchlassstellen 24b bei nicht durchgetrennten dritten Maschen einstellen. Weitere Durchlassstellen 24c und 24d sind durch die Anordnung der Linienelemente 12a bis 12d, 14a bis 14c, 26a bis 26c ausgebildet und bilden ein entsprechendes Muster aus. Somit ergibt sich ein in Querrichtung 6 nach einer Folge von zwei ersten Linienelementen 12a, 12b und zwei zweiten Linienelementen 14a, 14b wiederholende Folge und in Längsrichtung 4 nach zwei Maschen 16a, 16a' bzw. 20a, 20a' bzw. 28a, 28a' wiederholende Folge. Diese Mustereinheit wiederholt sich entlang der Trägerfläche 8 in Längs- und Querrichtung 4, 6 und ist sowohl auf der in den Fig. 3 und 4 gezeigten Unterseite als auch auf der in Fig. 5 gezeigten Oberseite sichtbar. Folglich weist die Trägerfläche 8 eine homogene Formstabilität und Durchlässigkeit für Fluide, wie für eine Schleifstaubabsaugung, auf.In the exemplary embodiment shown and described, the third line elements 26a to 26c, viewed in the longitudinal and transverse directions 4, 6, are separated into connecting elements on every second third loop, so that larger passage locations 24a are established at these points in comparison to passage locations 24b for third thirds not severed , Further passages 24c and 24d are formed by the arrangement of the line elements 12a to 12d, 14a to 14c, 26a to 26c and form a corresponding pattern. Thus, a sequence repeated in the transverse direction 6 following a sequence of two first line elements 12a, 12b and two second line elements 14a, 14b and in the longitudinal direction 4 after two stitches 16a, 16a 'or 20a, 20a' or 28a, 28a 'is repeated Episode. This pattern unit repeats along the support surface 8 in the longitudinal and transverse directions 4, 6 and is on both in the Fig. 3 and 4 shown underside as well as on the in Fig. 5 visible top visible. Consequently, the support surface 8 has a homogeneous dimensional stability and permeability to fluids, such as a Schleifstaubabsaugung on.

Fig. 5 zeigt eine Oberseite eines in den vorangegangenen Figuren gezeigten Haftverschlussteils 32. Aus der in Längs- und Querrichtung 4, 6 aufgespannten Trägerfläche 8 ragen Verbindungselemente 30a, 30a', 30a" des dritten Linienelements 26a und Verbindungselemente 30b, 30b', 30b" des dritten Linienelements 26b hervor. Die dritten Linienelemente 26a, 26b sind entsprechend den ersten Linienelementen (nicht bezeichnet) durch zweite Linienelemente 14a miteinander verbunden. Die Verbindungselemente 30a bis 30b" weisen jeweils eine pilzkopfförmige Verdickung am freien Ende auf und bilden einen hakenden Klettverschluss aus. Als Gegenstück für das Haftverschlussteil 32 kann beispielsweise ein Velours oder Flausch eingesetzt werden. Aus Fig. 5 ist die Regelmäßigkeit der Verbindungselemente 30a bis 30b" gut erkennbar, wobei in Längsrichtung 4 jede zweite dritte Masche 28a, 28a" und in Querrichtung 6 ebenfalls jede zweite, d.h., niemals unmittelbar benachbarte dritte Maschen 28a und 28b, aufgetrennt und zu Verbindungselementen 30a, 30a' ausgeformt ist. Fig. 5 shows an upper side of an adhesive closure part 32 shown in the preceding figures. From the carrier surface 8 spanned in the longitudinal and transverse directions 4, 6, connecting elements 30a, 30a ', 30a "of the third line element 26a and connecting elements 30b, 30b', 30b" of the third line element protrude 26b. The third line elements 26a, 26b are connected to each other according to the first line elements (not designated) by second line elements 14a. The connecting elements 30a to 30b "each have a mushroom-shaped thickening at the free end and form a hooked hook-and-loop fastener A counterpart for the adhesive closure part 32 may be, for example, a velor or fleece Fig. 5 is the regularity of the connecting elements 30a to 30b "clearly visible, wherein in the longitudinal direction 4 every second third loop 28a, 28a" and in the transverse direction 6 also every second, ie, never immediately adjacent third stitches 28a and 28b, separated and connecting elements 30a, 30a 'is formed.

Im gezeigten Beispiel ist für die dritten Linienelemente 26a bis 26c jeweils ein Monofilament, insbesondere aus isotaktischem Polypropylen, eingesetzt worden, es ist jedoch auch denkbar, einen eine Schleiffunktion sicherstellenden Werkstoff zur Ausbildung der dritten Linienelemente 26a bis 26c und insbesondere der Verbindungselemente 30a bis 30b" zu wählen. Die Verbindungselemente 30a bis 30b", wie in Fig. 6 im Detail gezeigt, können selbst als Schleifmittel ausgebildet sein, jedoch auch zusätzlich zu eine Schleiffunktion aufweisenden Funktionselementen auf die Trägerfläche 8 aufgebracht worden sein. Fig. 6 gut entnehmbar sind die pilzförmigen Verdickungen am freien Ende der Verbindungselemente 30a bis 30a" und die reihenförmige Anordnung der im Wesentlichen senkrecht aus der Trägerfläche 8 ragenden Verbindungselemente 30a bis 30a".In the example shown, a monofilament, in particular of isotactic polypropylene, has been used for the third line elements 26a to 26c, but it is also conceivable to provide a material that ensures a grinding function for forming the third line elements 26a to 26c and in particular the connecting elements 30a to 30b. The connecting elements 30a to 30b "as in Fig. 6 shown in detail, may themselves be designed as abrasive, but also in addition to a function of abrasive function elements have been applied to the support surface 8. Fig. 6 The mushroom-shaped thickenings are easily removable at the free end of the connecting elements 30a to 30a "and the row-shaped arrangement of the substantially vertically protruding from the support surface 8 connecting elements 30a to 30a".

Fig. 7 und 8 zeigen ein Halbzeug 34, mittels dessen ein weiteres Haftverschlussteil ausgebildet werden kann. Das Zwischenprodukt bzw. Halbzeug 34 zeichnet sich durch schlaufenartig an einer in Fig. 7 gezeigten Oberseite vorstehenden dritten Linienelementen 26', 26" bzw. dritten Maschen 28', 28" aus. Aus der in Fig. 8 gezeigten Unterseite des Halbzeugs 34 ist gut erkennbar, dass das die Funktionslage 2' ausbildende Fadensystem 10' vollständig aus Multifilamenten gebildet ist. Die Durchlassstellen 24', 24" ermöglichen einen guten Fluiddurchtritt durch die Funktionslage 2' und das Halbzeug 34 bzw. ein daraus gebildetes Haftverschlussteil. Fig. 7 and 8th show a semifinished product 34, by means of which a further adhesive closure part can be formed. The intermediate product or semifinished product 34 is characterized by a loop-like manner on an in Fig. 7 shown upper side projecting third line elements 26 ', 26 "and third stitches 28', 28" from. From the in Fig. 8 shown underside of the semifinished product 34 is clearly visible that the functional layer 2 'forming thread system 10' is formed entirely of multifilaments. The passage points 24 ', 24 "allow a good fluid passage through the functional layer 2' and the semi-finished product 34 or an adhesive closure part formed therefrom.

Das vorstehend beschriebene, sehr luftdurchlässige Haftverschlussteil 32 lässt sich auch insbesondere im Kraftfahrzeugbereich einsetzen und bevorzugt im Bereich der Sitzteilpolsterung von Kraftfahrzeugen. Insbesondere ist das Haftverschlussteil 32 geeignet, Polstermaterialien des Fahrzeugsitzes nach außen hin abzudecken; dennoch besteht nach wie vor die Möglichkeit der Luftführung durch die insoweit offenen Maschen des Haftverschlussteils, was neben einer Sitzkomforterhöhung auch die Möglichkeit eröffnet, den Sitz entsprechend wirksam zu klimatisieren, d.h., eine Heiz- und/oder Kühlluftführung optimal zu verwirklichen. Das sich das Haftverschlussteil aufgrund seiner Verschlusselemente ohne weiteres von dem sonstigen Polsterbezug oder den Polstermaterialien lösen lässt, besteht auch insoweit eine Austauschmöglichkeit gegen ein entsprechend konzipiertes Neu-Haftverschlussteil.The above-described, very air-permeable adhesive closure part 32 can also be used in particular in the motor vehicle sector and preferably in the area of the seat part upholstery of motor vehicles. In particular, the adhesive closure member 32 is adapted to cover cushioning materials of the vehicle seat to the outside; Nevertheless, there is still the possibility of air flow through the so far open stitches of the adhesive closure part, which in addition to a seat comfort increase also opens up the possibility to effectively air-condition the seat, that is, to optimally realize a heating and / or cooling air duct. The fact that the adhesive closure part can be easily detached from the other upholstery cover or upholstery materials due to its closure elements, there is also a possibility of exchange for a correspondingly designed new-adhesive closure part.
