Die Erfindung betrifft ein Verfahren zur Oberflächenfunktionalisierung eines Haftverschlußteiles, der mit einem korrespondierend ausgebildeten Haftverschlußteil einen wiederholt öffenbaren- und schließbaren Haftverschluß ausbildet, wobei zumindest eines der Haftverschlußteile zumindest teilweise auf einem Trägerteil angeordnete, vorstehende Stielteile aufweist, die jeweils an ihrer dem Trägerteil abgewandten Seite ein Kopfteil aufweisen und mit diesem ein Verschlußelement ausbilden.The invention relates to a method for surface functionalization of an adhesive closure part, which forms a repeatedly openable and closable adhesive closure with a correspondingly formed adhesive closure part, wherein at least one of the adhesive closure parts at least partially disposed on a support member, projecting stem parts, each on its side facing away from the carrier part Have head and form a closure element with this.

Durch die DE 10 2006 028 581 A1 ist ein gattungsgemäßes Verfahren nebst Vorrichtung zur Oberflächenfunktionalisierung von Haftverschlußteilen bekannt. Bei dem bekannten Verfahren wird mittels eines Protonen- und/oder Elektronenaustauschmediums, insbesondere in Form von Donatoren oder Kollektoren die Oberflächenenergie des Haftverschlußteils unter Einsatz von Hochenergie derart modifiziert, dass beschichtungsfrei und alterungsbeständig die chemisch-physikalischen Eigenschaften des Haftverschlußteil-Materiales einstellbar sind, indem sich Funktionsgruppen des Austauschmediums an das Haftverschlußteil-Material angliedern. Insbesondere durch den Einsatz basischer Elektronen-Donatoren wie Amino-, Amido- und/oder Imidogruppen und -Verbindungen läßt sich als Funktionsgruppe an der Oberseite des Haftverschlußteiles eine NH3-Gruppe einbringen, die mit weiteren Funktionsbaugruppen den Aufbau einer sogenannten asymmetrischen Harnstoffbindung erlaubt, die über eine weitere reaktive Gruppe verfügt, an die sich das Polyurethan von Schaummaterialien im Polsterschaumbereich ansiedeln läßt, was dergestalt zu einer ausgesprochen guten Anbindung des Haftverschlußteils im Formschaum führt und insbesondere in Bereichen der Fahrzeugtechnik eine große Rolle spielt. Mit dem bekannten Verfahren nebst zugehöriger Vorrichtung wird die gesamte Oberfläche des jeweiligen Haftverschlußteiles insoweit modifiziert.By the DE 10 2006 028 581 A1 is a generic method and device for surface functionalization of fastener parts known. In the known method, by means of a proton and / or electron exchange medium, in particular in the form of donors or collectors, the surface energy of the fastener part using high energy modified such that coating-free and aging resistant, the chemical-physical properties of the fastener part material can be adjusted by Attach functional groups of the exchange medium to the adhesive closure material. In particular, by the use of basic electron donors such as amino, amido and / or imido groups and compounds can be as a functional group at the top of the fastener part introduce a NH 3 group, with other functional assemblies the construction of a so-called asymmetric urea bond allowed, which has a further reactive group to which the polyurethane of foam materials can settle in the upholstery foam area, which in such a way leads to a very good connection of the adhesive closure part in the molded foam and plays a major role in particular in areas of automotive engineering. With the known method together with the associated device, the entire surface of the respective adhesive closure part is modified in this respect.

Durch die EP 1 082 032 B1 ist ein vergleichbares Haftverschlußteil bekannt, insbesondere zum Einschäumen bei Polsterteilen von Fahrzeugsitzen bei deren Herstellung, mit Haftelementen auf der einen Seite zum Verbinden mit korrespondierenden Haftelementen eines anderen Haftverschlußteils unter Bildung eines Haftverschlusses und mit einem Verbindungsmittel in der Art eines Haftmediums als Funktionsmedium auf der anderen Seite des Haftverschlußteils zum Herstellen einer Verbindung mit dem jeweiligen Schaummaterial, wobei das Haftmedium in das Haftverschlußmaterial selbst eingebracht ist und wobei das Haftmedium aus Fluor besteht. Insbesondere wird das Fluor gasförmig in einer Stickstoffatmosphäre auf die gesamte Oberseite des Haftverschlußteiles mit seinen Bestandteilen Stiel-, Kopf- und Trägerteil nach deren vollständiger Herstellung aufgebracht. Dergestalt läßt sich eine bessere Anbindung des Haftverschlußteiles an das korrespondierende Schaummaterial erreichen als mittels den sonst auf diesem Gebiet üblicher Weise eingesetzten Klebstoffen.By the EP 1 082 032 B1 a comparable adhesive closure part is known, in particular for foaming upholstery parts of vehicle seats in their manufacture, with adhesive elements on one side for connection to corresponding adhesive elements of another adhesive closure part to form an adhesive closure and with a connecting means in the form of an adhesive medium as a functional medium on the other side the adhesive closure member for bonding to the respective foam material, wherein the adhesive medium is incorporated in the adhesive closure material itself, and wherein the adhesive medium is fluorine. In particular, the fluorine is applied in gaseous form in a nitrogen atmosphere on the entire top of the fastener part with its components stem, head and support part after their complete production. In this way, a better connection of the adhesive closure part to the corresponding foam material can be achieved than by means of the adhesives otherwise commonly used in this field.

Durch die EP 1 082 031 B1 ist hingegen ein sogenanntes Sol-Gel-Verfahren bekannt, um die Oberfläche von Haftverschlußteilen nano-kompositär zu beschichten, wobei die dahingehend aufgebrachte Beschichtung schaumabweisend wirkt und dem möglichen Eindringen des Schaummaterials in die Zwischenräume der Verschlußelemente beim Ausschäumen wirksam entgegensteht, obwohl der Schaum Viskositäten aufweisen kann, die geringer sind als die von Wasser, um dergestalt das Verschlußmaterial für den späteren Eingriff von korrespondierenden Verschlußelementen eines weiteren Haftverschlußteils in der Funktion zu erhalten.By the EP 1 082 031 B1 However, a so-called sol-gel method is known to coat the surface of fastener parts nano-composite, wherein the effect applied coating foam repellant and effectively precludes the possible penetration of the foam material in the interstices of the closure elements during foaming, although the foam have viscosities can be lower than that of water, thus the closure material for the to obtain later engagement of corresponding closure elements of another adhesive closure member in the function.

Des weiteren ist durch die WO 2007/036252 ein Verfahren zum Herstellen eines Festlegegegenstandes, vorzugsweise in Form eines Haftverschlußteiles bekannt, umfassend das Ausbilden einer Trägerstruktur als Trägerteil, die mit stielartigen Festlegeelementen versehen wird, die zumindest paarweise über ein Zwischenelement unter Bildung eines krampen-, insbesondere U-förmigen Festlegeteiles miteinander verbunden werden, wobei die stielartigen Festlegeelemente die Trägerstruktur durchgreifen und über diese vorstehen und sich das zwischen diesen Festlegeelementen erstreckende Zwischenelement an der Trägerstruktur angeordnet wird. Durch das Einbringen des jeweiligen Festlegeteiles als Ganzes in die Trägerstruktur, das hierfür als Formteil vordem Einbringen krampen-, insbesondere U-förmig ausgebildet wird, läßt sich unter Einsatz einer Art Schußeinrichtung für die Festlegeteile diese in hoher Geschwindigkeit mit der Trägerstruktur in Verbindung bringen, wobei sich überraschend gute Produktqualitäten erreichen lassen. Die dahingehend padförmigen Haftverschlußteile sind der Fachwelt auch unter der Markenbezeichnung Duotec® bekannt geworden, wobei dahingehende Haftverschlußteile auch gewebt, gewirkt oder gestrickt sein können. Die aus einem thermisch gut verarbeitenden Kunststoff bestehenden Festlegeelemente, beispielsweise bestehend aus Polypropylen oder Polyamid, die sich auch in metallförmigen Trägern definiert festlegen lassen, weisen keinerlei Oberflächenmodifizierung auf.Furthermore, by the WO 2007/036252 a method for producing a fixing object, preferably in the form of an adhesive closure part, comprising forming a support structure as a support part which is provided with handle-like fixing elements, which are connected together at least in pairs via an intermediate element to form a cramped, in particular U-shaped fixing part, wherein the handle-like fixing elements pass through the support structure and protrude beyond it and the intermediate element extending between these fixing elements is arranged on the support structure. By introducing the respective fixing part as a whole into the support structure, which is cramped for this purpose as a molding before introducing, in particular U-shaped, can be using a kind of firing device for the fixing these bring in high speed with the support structure in conjunction can achieve surprisingly good product qualities. The thus pad-shaped fastener fastener parts have become known in the art under the brand name Duotec®, said pertinent parts can also be woven, knitted or knitted. The existing of a thermally well-processing plastic fixing elements, for example consisting of polypropylene or polyamide, which can be defined defined in metal supports, have no surface modification.

Im Rahmen der gängigen Verwendungspraxis hat sich bei dahingehenden Verschlüssen gezeigt, dass, wenn ein Haftverschlußteil mit einem korrespondierend ausgebildeten, insbesondere gleich ausgebildeten Haftverschlußteil einen wiederholt öffenbaren- und schließbaren Verschlußmechanismus ausbilden, beim Ineingriffbringen der benachbarten Verschlußelemente zwecks Schließen des Verschlusses sehr hohe Schließkräfte entstehen, so dass von Hand sehr hohe Montagekräfte aufzubringen sind, wohingegen die in der Gegenrichtung zu realisierenden Haltekräfte um ein ungewolltes Auseinanderbringen oder Lösen der Verschlußelemente zu vermeiden, die zu erreichenden Haftkraftwerte der Höhe nach noch Wünsche offen lassen. Insbesondere beim Auftreten von Vibrationen und sonstigen Erschütterungen ist es zumindest bei einem Teil der auf dem Markt erhältlichen Verschlußsysteme möglich, dass es ungewollt zu einem Lösen der Haftverschlußteile kommen kann, beispielsweise mit der Folge, dass auch schwere Wandpaneelen (Dachhimmel) sich von zugehörigen Fahrzeug-Rahmenteilen ungewollt lösen können, was mit einem gewissen Gefährdungspotential einhergeht.Within the scope of current practice, it has been found in the case of such closures that, when an adhesive closure part with a correspondingly designed, in particular identically formed adhesive fastener part forms a repeatedly openable and closable closure mechanism, very high closing forces occur when the adjacent closure elements are engaged in order to close the closure. so that by hand very high assembly forces are applied, whereas to be realized in the opposite direction holding forces to prevent unintentional disassembly or loosening of the closure elements, the achievable adhesive force levels of height still leave something to be desired. In particular, when vibrations and other shocks occur, it is possible, at least for some of the closure systems available on the market, that it may unintentionally come to a release of the fastener parts, for example, with the result that even heavy wall panels (headliner) of associated vehicle Frame parts can solve unintentionally, which is associated with a certain hazard potential.

Ausgehend von diesem Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, ein Verfahren nebst einem Haftverschlußteil zur Verfügung zu stellen, das die beschriebenen Nachteile nicht aufweist, insbesondere geringe Schließkräfte beim Schließen des Haftverschlusses ermöglicht, bei dennoch hohen Haltekräften für den insoweit geschlossenen Haftverschluß. Eine dahingehende Aufgabe löst ein Verfahren mit den Merkmalen des Patentanspruches 1 sowie ein Haftverschlußteil mit den Merkmalen des Patentanspruches 10.Based on this prior art, the invention has for its object to provide a method together with a fastener part available, which does not have the disadvantages described, in particular low closing forces when closing the fastener allows yet high holding forces for the extent closed adhesive fastener. This object is achieved by a method having the features of patent claim 1 and an adhesive closure part having the features of patent claim 10.

Dadurch, dass gemäß dem kennzeichnenden Teil des Patentanspruches 1 mindestens ein Teil der Stielteile eines Haftverschlußteiles mit einem Funktionsmedium versehen und die zuordenbaren Kopfteile hiervon weitgehend oder vollständig freigehalten werden, sind die Schließkräfte zum Ineingriffbringen der korrespondierenden Verschlußelemente unter Bildung des geschlossenen Haftverschlusses reduziert und die Haltekräfte bis zum Auseinanderbringen der korrespondierenden Verschlußelemente zum Öffnen des geschlossenen Haftverschlusses erhöht. Die vom Funktionsmedium nicht berührten Kopfteile weisen insoweit ein günstiges Gleitverhalten auf, dass diese beim Ineingriffbringen im wesentlichen widerstandsfrei aneinander in die durch die Stielteile des anderen Verschlußteils gebildeten Zwischenräume vorbeigleiten können, so dass insoweit die Schließkräfte reduziert sind. Ist der Verschluß geschlossen, kommen die randseitigen Bereiche der jeweiligen Kopfteile, die zwischen die den Zwischenraum bildenden Abstände von benachbarten Stielteilen des anderen Verschlußteiles eingreifen, in Anlage mit dem Funktionsmedium des jeweils benachbart angeordneten Stielteils, das insoweit die Friktion erhöht, um dergestalt das Auseinanderbringen der korrespondierenden Verschlußelemente zu erschweren, was zu einer Erhöhung der Haltekräfte im gewünschten Rahmen bis zum Öffnungsvorgang des Verschlusses führt. Je nach geeignetem Funktionsmedium und eingesetztem Kunststoffmaterial für die Verschlußelemente lassen sich die angesprochenen Schließkräfte halbieren, wohingegen die Haltekräfte um das Doppelte und mehr erhöht sein können. Auf diese Art und Weise läßt sich sicherstellen, dass mit dem jeweiligen Haftverschluß zusammenwirkende Komponenten, wie Dach- oder Wandpaneelen, sich nicht ungewollt von der Grundstruktur lösen können, selbst wenn diese Schwingungen oder starken Vibrationen ausgesetzt sind. Auch ist für das Montagepersonal das Schließen des Verschlusses mit seinen beiden korrespondierenden Haftverschlußteilen deutlich erleichtert, so dass sich effizient Einbauteile an Grundkonstruktionen festlegen lassen.Characterized in that according to the characterizing part of claim 1 at least a part of the handle parts of a fastener part provided with a functional medium and the attributable head parts thereof are largely or completely kept free, the closing forces for engaging the corresponding closure elements to form the closed adhesive closure are reduced and the holding forces to increased to bring apart the corresponding closure elements for opening the closed adhesive closure. The head parts, which are not touched by the functional medium, have a favorable sliding behavior insofar as they engage one another substantially without resistance when they are engaged can pass past the intermediate spaces formed by the stem parts of the other closure part, so that in this respect the closing forces are reduced. If the closure is closed, the marginal areas of the respective head parts, which engage between the spacings forming spacings of adjacent stem parts of the other closure part, come into contact with the functional medium of the respectively adjacent stem part, which increases the extent to the extent to the disassembly of the To complicate corresponding closure elements, which leads to an increase in the holding forces in the desired frame until the opening operation of the closure. Depending on the suitable functional medium and plastic material used for the closure elements, the aforementioned closing forces can be halved, whereas the holding forces can be increased by twice and more. In this way, it can be ensured that with the respective adhesive closure cooperating components, such as roof or wall panels, can not unintentionally detach from the basic structure, even if they are exposed to vibration or strong vibration. It is also much easier for the assembly staff to close the closure with its two corresponding adhesive closure parts, so that it is possible to efficiently fix built-in components to basic structures.

Als besonders bevorzugt hat es sich gezeigt, als Funktionsmedium Halogene in der Gasphase in der Art einer Beschichtung zumindest auf einen Teil der Stielteile eines Haftverschlußteiles aufzubringen. Vorzugsweise sind jedoch alle Stielteile eines jeden Haftverschlußteiles, die paarweise einander zugehörig den Haftverschluß ausbilden, dergestalt mit dem Funktionsmedium versehen. Als Halogen dient vorzugsweise Fluor oder eines seiner Verbindungen wie Chlorfluorid (CIF) oder Chlortrifluorid (CIF3).It has proven to be particularly preferable to apply halogens in the gas phase in the manner of a coating to at least part of the stem parts of an adhesive closure part as the functional medium. Preferably, however, all the stem parts of each adhesive closure part, which form the adhesive closure in pairs belonging to one another, are provided with the functional medium in this way. The halogen used is preferably fluorine or one of its compounds, such as chlorofluoride (CIF) or chlorotrifluoride (CIF 3 ).

Mit dem Verfahren lassen sich sowohl gegossene Verschlüsse mit dem Funktionsmedium versehen, als auch gewebte oder gestrickte Verschlüsse. Bei den gegossenen Verschlüssen werden zunächst zusammen mit dem Trägerteil die Stielteile erstellt und dann das Fluor-Funktionsmedium in der Gasphase über eine geeignete Vorrichtung aufgebracht. Anschließend werden die erwärmten Stielenden in Kopfform gebracht, so dass auf jeden Fall die Oberseite der Verschlußköpfe funktionsmedienfrei ist, wohingegen die Stielteile das Funktionsmedium außenumfangsseitig aufweisen. Ist als thermoplastisches Kunststoffmaterial Polypropylen eingesetzt, ergeben sich besonders günstige Abgleiteigenschaften für die insoweit nicht behandelte Kopfoberseite des Verschlußkopfes.With the method, both cast closures can be provided with the functional medium, as well as woven or knitted closures. In the cast closures, the stem parts are first created together with the carrier part and then the fluorine functional medium is applied in the gas phase via a suitable device. Subsequently, the heated stem ends are brought into head shape, so that in any case the top of the closure heads is free of functional media, whereas the stem parts have the functional medium on the outer peripheral side. If polypropylene is used as the thermoplastic material, the result is particularly favorable Abgleiteigenschaften for the extent not treated head top of the closure head.

Wird ein Web- oder ein Strickverfahren für den Erhalt eines Haftverschlußteils aus Einzel- und/oder Multifilamenten eingesetzt, sind zumindest die eingewebten oder eingestrickten vorstehenden Schlaufen entsprechend zu fluorieren und nach Auftrennen der jeweiligen Schlaufe können die freien Schlaufenenden, die insoweit die Stielteilenden ausbilden, angeflämmt oder mit einem sonstigen Wärmeeintrag versehen das Kopfteil ausbilden, in dem sich das thermoplastische Kunststoffmaterial aufgrund seiner Oberflächenspannung in eine Art kalottenförmigen oder halbkugelförmigen Kopfteil umwandelt, was auch mittels einer zusätzlichen Kopfformeinrichtung unterstützt werden kann. Sofern man nicht alle Schlaufen derart modifiziert, können insoweit Haftverschlußteile ausgebildet werden, die neben Verhakungsschlaufen auf der einen Oberseite des Trägerteils auch die Verschlußköpfe nebst zugehörigen Stielteilen als Verschlußelemente aufweisen. Auch lassen sich die aufgeschnittenen Schlaufen partiell zu hakenförmigen Verschlußelementen umgestalten, so dass neben pilzkopfförmigen Verschlußelementen auch hakenförmige Verschlußteile auf der Oberseite eines Haftverschlußteils vorstehen können.If a weaving or a knitting method is used to obtain a single and / or multifilament fastener part, at least the woven-in or knitted protruding loops must be fluorinated accordingly, and after the respective loop has been severed, the free loop ends which form the end-pieces can be flamed or provided with a different heat input form the head part, in which the thermoplastic material converts due to its surface tension in a kind dome-shaped or hemispherical head part, which can also be supported by means of an additional head molding device. Unless all loops are modified in this way, adhesive closure parts can be formed in this respect, which in addition to hook loops on the one upper side of the carrier part also have the closure heads together with associated handle parts as closure elements. Also, the cut loops can be partially reshaped to hook-shaped closure elements, so that in addition to mushroom-shaped closure elements and hook-shaped closure members can protrude on top of a fastener part.

Sofern auch das Trägerteil des jeweiligen Haftverschlußteils im skizzierten Sinne oberflächenfunktionalisiert wird, erlaubt dies aufgrund der reaktiven Funktionsgruppen des Fluormediums eine verbesserte Anhaftung eines Appreturmittels, wobei je nach gewähltem Appreturmittel der Verschluß flammbeständig und hitzresistent ausgelegt werden kann und gleichzeitig wird bei gewebten Verschlüssen über die Appretur die Anhaftung des eingewebten Verschlußelementes gegenüber dem Trägerteil verbessert, so dass insoweit ein ungewolltes Herausziehen des Verschlußelementes im Betrieb des Verschlusses mit Sicherheit vermieden ist.If the carrier part of the respective adhesive closure part is also surface-functionalized in the sense outlined, this allows an improved adhesion of a finishing agent due to the reactive functional groups of the fluorine medium. wherein depending on the selected finishing agent, the closure flame-resistant and heat-resistant can be interpreted and at the same time the adhesion of the woven fastener to the support member is improved in woven closures on the finish, so far as an accidental pulling out of the closure element during operation of the closure is avoided with certainty.

In the following the method according to the invention will be explained in more detail with reference to a product example for a fastener part according to the drawing. This show in principle and not to scale representation of the
Fig.1
a functional representation of an adhesive closure;
Fig.2
in the manner of a time schedule, the production of a surface-functional adhesive closure part from a precursor to a final stage.

Der als Ganzes mit 10 bezeichnete, in der Fig.1 teilweise dargestellte Haftverschluß weist ein Haftverschlußteil 12 auf, das mit einem korrespondierend ausgebildeten Haftverschlußteil 14 den wiederholt öffenbaren und schließbaren Haftverschluß 10 ausbildet. Dahingehend aufgebaute Haftverschlüsse sind von ihrer Funktion her bei den Fach- und Endabnehmerkreisen auch unter dem Markennamen Kletten®-Haftverschluß einschlägig bekannt. Die in der Fig.1 propagierte Verschlußlösung ist darüber hinaus unter der Marke Microduotec® auf dem Markt. Wie die Fig.1 weiter zeigt, weist jedes Haftverschlußteil 12,14 ein Trägerteil 16 auf, das sich band- oder flächenartig als dreidimensionaler Gegenstand auch in die Zeichenebene hinein und aus dieser heraus erstreckt und zumindest auf der einen Seite des jeweiligen Trägerteils 16 sind Stielteile 18 angeordnet, die an ihrem freien stirnseitigen Ende und mithin dem jeweiligen Trägerteil 16 abgewandt mit einem Kopfteil 20 einstückig versehen sind. Jedes Stielteil 18 bildet insoweit mit seinem Kopfteil 20 ein gegossenes Verschlußelement 22 aus, das im vorliegenden Fall auf der Oberseite des Trägerteils 16 in Reihen in Quer- und Längsrichtung vorsteht.The designated as a whole with 10, in the Fig.1 partially shown adhesive closure has an adhesive closure member 12 which forms the repeatedly openable and closable adhesive closure 10 with a correspondingly formed adhesive closure part 14. To this end constructed fasteners are known in their function in the professional and Endabnehmerkreisen also under the brand name Kletten®-adhesive closure pertinent. The in the Fig.1 propagated closure solution is also under the brand Microduotec ® on the market. As the Fig.1 further shows, each fastener part 12,14 on a support member 16 which extends band-like or planar like a three-dimensional object in and out of the drawing and at least on one side of the respective support member 16 are arranged stem parts 18, the their free end face and therefore facing away from the respective support member 16 are provided with a head part 20 in one piece. Each handle part 18 forms so far with its head part 20 from a cast closure element 22, which projects in the present case on the upper side of the support member 16 in rows in the transverse and longitudinal directions.

Wie die Darstellung nach der Fig.1 weiter zeigt, greifen die Kopfteile 20 mit ihrem zuordenbaren Stielteil 18 des einen Haftverschlußteils 12 in Zwischenräume 24 des anderen Haftverschlußteils 14 ein, wobei die dahingehenden Zwischenräume 24 im wesentlichen durch die Abstände der benachbarten Stielteile eines Haftverschlußteils 12,14 gebildet sind, wobei entsprechend auch in dem anderen Haftverschlußteil 12 entsprechende Zwischenräume 24 vorhanden sind. Für einen sicheren Eingriff der Haftverschlußteile 12,14 ineinander und für den Erhalt hoher Haltekräfte bei geschlossenem Haftverschluß, wie er in Blickrichtung auf die Fig.1 in der linken Bildhälfte dargestellt ist, ist es vorteilhaft, wenn die Kopfteile 20 außenumfangsseitig einen entsprechend scharf ausgebildeten Umfassungsrand 26 aufweisen, der sich jedoch in gewisser Weise als Hindernis darstellen kann, sofern in Blickrichtung auf die Fig.1 gesehen auf der rechten Bildhälfte die Verschlüsse schließend in Eingriff miteinander zu bringen sind, was durch den insoweit scharfkantigen Kopfteilverlauf gehemmt ist. Die gegenläufig orientierten Schließ- und Haltekräfte sind in der Fig.1 mit SK und HK als Kraftpfeile wiedergegeben. Des besseren Verständnisses wegen sei noch klargestellt, dass die Verschlußelemente 22 regelmäßig aus einem thermoplastischen Kunststoffmaterial gebildet sind, das insoweit elastisch nachgiebig das Ineinandereingreifen der Kopfteile 20 von benachbarten Haftverschlußteilen ermöglicht und insoweit auch den Lösevorgang unterstützt, um den Verschluß zu öffnen.As the presentation after the Fig.1 further shows, engage the head parts 20 with their assignable handle portion 18 of the one fastener part 12 in the interstices 24 of the other fastener part 14, wherein the pertinent gaps 24 are formed substantially by the distances of the adjacent handle parts of a fastener part 12,14, wherein also in the other adhesive closure member 12 corresponding gaps 24 are present. For a secure engagement of the fastener parts 12,14 into each other and for obtaining high holding forces with the fastener closure closed, as he looking in the direction of Fig.1 is shown in the left half of the picture, it is advantageous if the head parts 20 on the outer peripheral side have a correspondingly sharply formed Umfassungsrand 26, which may, however, be in some way as an obstacle, provided in view of the Fig.1 seen on the right half of the picture closing the closures are to bring into engagement with each other, which is inhibited by the so far sharp-edged head part course. The oppositely oriented closing and holding forces are in the Fig.1 reproduced with SK and HK as force arrows. For better understanding, it should be further clarified that the closure elements 22 are regularly formed from a thermoplastic material, which so far elastically yielding allows the interengaging of the head parts 20 of adjacent fastener parts and also supports the release process to open the closure.

Dadurch, dass man nun zumindest im Sinne des erfindungsgemäßen Verfahrens die Stielteile 18 eines Haftverschlußteils 12 oder 14 derart mit einem Funktionsmedium versieht und die zuordenbaren Kopfteile 20 hiervon weitgehend oder vollständig freihält, lassen sich die Schließkräfte SK zum Ineingriffbringen der korrespondierenden Verschlußelemente 22 unter Bildung des geschlossenen Haftverschlusses 10 reduzieren und die Haltekräfte HK bis zum Auseinanderbringen der korrespondierenden Verschlußelemente 22 unter Bildung des geöffneten Haftverschlusses 10 deutlich erhöhen. Ursächlich hierfür ist, dass die vom Funktionsmedium nicht berührten Kopfteile 20 auf ihrer Oberseite insoweit ein günstiges Gleitverhalten aufweisen, dass diese beim Ineingriffbringen im wesentlichen widerstandsfrei aneinander in die durch die Stielteile 18 des anderen Verschlußteils 12 oder 14 gebildeten Zwischenräume 24 vorbeigleiten können, so dass insoweit die Schließkräfte SK reduziert sind. Die Funktionsmedien freigehaltenen Kopfteile 20 weisen vom Kunststoffverhalten her die günstigen Gleiteigenschaften auf, wohingegen die Stielteile, an denen das Funktionsmedium verbleibt, zu einer Erhöhung der Friktion führen und mithin zu einem verbesserten bleibenden Aneinanderhalt, bevor ein Grenzwert der Haltekräfte HK überschritten wird, was zwangsläufig zum Lösen des geschlossenen Haftverschlusses 10 führt, was zur Realisierung eines wiederholt öffen- und schließbaren Kletten®-Haftverschlusses ja auch erwünscht ist.Characterized in that now at least in the sense of the method according to the invention, the stem parts 18 of a fastener part 12 or 14 so provided with a functional medium and the assignable head parts 20 thereof largely or completely free, the closing forces SK can reduce the engagement of the corresponding closure elements 22 to form the closed adhesive closure 10 and increase the holding forces HK until the removal of the corresponding closure elements 22 to form the open adhesive closure 10 significantly. The reason for this is that the head parts 20, which are not touched by the functional medium, have a favorable sliding behavior on their upper side, so that they can slip past each other substantially without resistance into the intermediate spaces 24 formed by the handle parts 18 of the other closure part 12, so that in this respect the closing forces SK are reduced. The functional media freed head parts 20 have the plastic behavior of the favorable sliding properties, whereas the stem parts, where the functional medium remains, lead to an increase in friction and thus to an improved lasting abutment before a limit of the holding forces HK is exceeded, which inevitably Loosening of the closed adhesive closure 10 leads, which is also desirable for the realization of a repeatedly openable and closable Velcro ® -Zeilverschlusses.

Durch gezielten Einsatz des Funktionsmediums lassen sich insoweit die Schließkräfte deutlich reduzieren, was für einen Monteur die Montagearbeiten erleichtern hilft und im Gegenzug sind die Haltekräfte HK deutlich erhöht, d.h. der einmal geschlossene Haftverschluß 10 trägt hohe Lasten oder Gewichte, was beispielsweise eine Rolle spielt, wenn im Automobilbau im Fahrzeuginneren der Dachhimmel an der sonstigen Fahrzeugkarosserie-Grundkonstruktion gegen die Schwerkraft festgelegt wird. Es hat sich gezeigt, dass auch bei Umgebungsbedingungen mit hohen Temperaturen und im Fahrbetrieb bei entsprechend auftretenden Vibrationen und Schwingungen jedenfalls der mittels von dahingehend modifizierten Haftverschlüssen 10 festgelegte Dachhimmel in seiner Montagestellung verbleibt.By targeted use of the functional medium, the closing forces can be significantly reduced, which helps the assembly work easier for a fitter and in return, the holding forces HK are significantly increased, ie once closed adhesive fastener 10 carries high loads or weights, which plays a role, for example in the automotive industry in the vehicle interior of the headliner is fixed to the other vehicle body basic construction against gravity. It has been found that even under ambient conditions with high temperatures and when driving in accordance with vibrations and vibrations occurring in any case remains fixed by means of modified adhesive fasteners 10 headliner in its mounting position.

Der in Fig.1 gezeigte Verschluß 10 läßt sich als Band- oder Flächenware mittels eines Gießformgebungsverfahrens erhalten, das man fachsprachlich auch mit Chill-Roll-Verfahren benennt. Ein dahingehendes Formgebungsverfahren ist beispielhaft in der DE 10 2006 028 581 A1 aufgezeigt, wobei die einzige Figur dieser Anmeldung Teile einer Herstellvorrichtung zeigt mit einem Extruderkopf als Zuführeinrichtung für in plastischem oder flüssigem Zustand befindlichen, insbesondere thermoplastischem Kunststoffmaterial, wie Polypropylen (PP), das als ein Band, dessen Breite derjenigen des herzustellenden Haftverschlußteils 12 oder 14 entspricht, einem Spalt zwischen einem Druckwerkzeug und einem Formwerkzeug zugeführt wird, die als Walzen ausgebildet in der Art eines Walzengestühls miteinander zusammenwirken. Für die eigentliche Formgebung weist die Formwalze am Umfang ein Formgebungssieb auf mit einzelnen Formhohlräumen, die die einzelnen Verschlußelemente 22, also jeweils Stielteil 18 mit Kopfteil 20, auf einem Trägerteil 16 generieren.The in Fig.1 Shutter 10 shown can be obtained as a strip or flat goods by means of a Gießformgebungsverfahrens, which is called technical language with chill-roll process. A pertinent shaping method is exemplary in the DE 10 2006 028 581 A1 the sole figure of this application shows parts of a manufacturing apparatus with an extruder head as a feeder for in plastic or liquid state, in particular thermoplastic material such as polypropylene (PP), which corresponds to a band whose width of that of the adhesive closure member 12 or 14 to be produced , is supplied to a gap between a pressure tool and a mold, which are formed as rollers formed in the manner of a roller stalls cooperate with each other. For the actual shaping, the forming roller has on the circumference a shaping screen with individual mold cavities which generate the individual closure elements 22, ie in each case handle part 18 with head part 20, on a carrier part 16.

In Abkehr zu dieser bekannten Lösung wird im Rahmen des hier vorliegenden erfindungsgemäßen Verfahrens als Vorprodukt nur das Trägerteil 16 mit den einstückig angegossenen Stielteilen 18 erhalten, ohne den jeweiligen Kopfteil 20 anzuformen. Unabängig von der Geometrie der Stielteile als Stielteilzylinder oder als Stielteilhyperboloid kommen diese dann zusammen mit dem Trägerteil 16 in eine übliche Fluorierungseinrichtung, wie sie beispielhaft in der einzigen Figur der EP 1 082 032 B1 dargestellt ist, wobei bevorzugt ein Eintrag des Funktionsmediums in Form von Fluorgas zu 3 bis 10 % bei Raumtemperatur und einem Unterdruck von ca. 650 millibar in einer geschlossenen Auftragskammer durchgeführt wird. Die Fluorierung kann insoweit kontinuierlich betrieben werden, vorzugsweise in einem ausgewählten Temperaturbereich von 40°C bis 50°C unter Stickstoffatmosphäre und entsprechend anstehendem Unterdruck in der genannten Behandlungskammer.In contrast to this known solution, in the context of the present inventive method as a precursor only the support member 16 is obtained with the integrally cast handle parts 18, without forming the respective head part 20. Irrespective of the geometry of the stem parts as a stem part cylinder or as Stielteilhyperboloid these then come together with the support member 16 in a conventional fluorination, as exemplified in the single FIG EP 1 082 032 B1 is shown, wherein preferably an entry of the functional medium in the form of fluorine gas to 3 to 10% at room temperature and a reduced pressure of about 650 millibar is carried out in a closed application chamber. The fluorination can be operated continuously so far, preferably in a selected temperature range of 40 ° C to 50 ° C under a nitrogen atmosphere and correspondingly pending negative pressure in said treatment chamber.

Sind die Oberseite des jeweiligen Trägerteils sowie die Stielteile 18 außenumfangsseitig mit dem Funktionsmedium vorzugsweise in Form des gasförmig aufgebrachten Fluors beschichtet, wird in einem sich anschließenden bekannten Kalander-Walzverfahren das Stielende zum Kopfteil 20 umgeformt, was Kopfgeometrien ergibt gemäß der Darstellung nach der Fig.1 mit entsprechend eben ausgebildeter Stirnfläche, die mittels eines separaten Kopfformwerkzeugs nachgeformt werden können, beispielsweise zu im Querschnitt gesehen mehreckigen Kopfformen.If the upper side of the respective carrier part and the stem parts 18 are coated on the outer peripheral side with the functional medium, preferably in the form of the gaseous fluorine, the stem end is reshaped into the head part 20 in a subsequent known calender rolling process, which results in head geometries according to FIG Fig.1 with correspondingly flat end face, which can be reshaped by means of a separate head molding tool, for example, to polygonal in cross-section head shapes.

Eine andere Möglichkeit, dahingehende Haftverschlüsse 10 herzustellen, ist beispielsweise durch die EP 1 534 096 B1 bekannt, die ein flächenförmiges Haftverschlußteil 12 für einen Haftverschluß 10 betrifft, bei dem lösbar miteinander korrespondierende Verschlußelemente 22 in Eingriff miteinander bringbar sind. Die dahingehende Lösung besteht aus einem Grundgewebe als Trägerteil 16 aus Kettfäden und Schußfäden und verfügt ferner über mindestens einen Funktionsfaden 28 (vgl. Fig.2), der vorzugsweise als Monofilament-Faden ausgebildet das Grundgewebe teilweise durchgreift und die Verschlußelemente 22 ausbildet. Ein dahingehend gewebter Verschluß ist auf dem Markt auch unter der Markenbezeichnung Duotec® frei käuflich zu erhalten.Another way to produce pertinent adhesive fasteners 10, for example, by the EP 1 534 096 B1 known, which relates to a sheet-like adhesive closure member 12 for an adhesive closure 10, in which releasably mutually corresponding closure elements 22 are engageable with each other. The pertinent solution consists of a base fabric as a carrier part 16 of warp threads and weft threads and also has at least one functional thread 28 (see. Fig.2 ), which preferably formed as a monofilament thread partially penetrates the ground fabric and forms the closure elements 22. A woven closure is available on the market under the brand name Duotec ® freely available.

In Blickrichtung auf die Fig.2 gesehen ist ganz oben dargestellt das vorstehend beschriebene Ausgangsprodukt wiedergegeben. Benötigt man kein Verschlußteil mit Schlaufen, sondern mit pilz- oder hakenförmigem Charakter, wird entlang der Trennlinie 30 die Verschlußschlaufe über eine geeignete Schnittvorrichtung (nicht dargestellt), was im Stand der Technik üblich ist, aufgeschnitten.In the direction of the Fig.2 is seen at the top represented the above-described starting material. If you do not need a closure part with loops, but with mushroom or hook-shaped character, along the parting line 30, the closure loop via a suitable cutting device (not shown), which is common in the art, cut open.

In Abkehr zu dieser bekannten Lösung wird bei dem vorliegenden erfindungsgemäßen Verfahren die Verschlußschlaufe 32, gebildet aus dem Funktionsfaden 28, jedoch zunächst beibehalten, und das insoweit modifizierte Haftverschlußteil 12 vorab einer Fluorierung zugeführt, wie vorstehend bereits beschrieben. Die mit F bezeichneten Fluorfunktionsgruppen umschließen insoweit regelmäßig die gesamte äußere Oberfläche der Verschlußschlaufe 32 und regelmäßig wird auch noch das Trägerteil 16, im vorliegenden Fall bestehend aus Kett- und Schußfäden, mitfluoriert. Im nachfolgenden weiteren Schritt wird dann die Verschlußschlaufe 32, wie bereits aufgezeigt, entlang der Trennlinie 30 aufgeschnitten und die freien Schlaufenenden, die aufgrund der Eigenelastizität des eingewebten Materials etwas voneinander wegspringen, werden endseitig angeflämmt, so dass aufgrund der Oberflächenspannung des eingesetzten Kunststoffmaterials Kopfteile 20 entstehen, die halbkugelförmig oder kalottenartig ausgestaltet sind gemäß der in Blickrichtung auf die Fig.2 gesehen untersten Darstellung.In contrast to this known solution in the present inventive method, the closure loop 32 formed from the functional thread 28, but initially maintained, and the extent modified Adhesive closure part 12 is previously supplied to a fluorination, as already described above. The fluorine function groups denoted by F so far regularly surround the entire outer surface of the closure loop 32 and regularly also the support member 16, in the present case consisting of warp and weft threads, fluorinated. In the following further step, the closure loop 32, as already shown, then cut along the dividing line 30 and the free loop ends, which jump away from each other due to the intrinsic elasticity of the woven material something, flaring end, so that due to the surface tension of the plastic material used head parts 20 arise , which are hemispherical or dome-shaped according to the direction of the Fig.2 seen lowest representation.

Da für die Umformung der Stielteile 18 zum jeweiligen Kopfteil 20 mehr oder minder die jeweilige Hälfte der Verschlußschlaufe 32 eingesetzt ist, wird insoweit bei der Kopfteilbildung auch das Fluor als Funktionsmedium mit angeschmolzen, was dazu führt, dass im Bereich der Kopfteilbildung sich unter Wärmeeinfluß das Fluor entweder verflüchtigt oder fein dispergiert im Inneren des Kopfteils 20 sich statistisch verteilt. Letztendlich ist aber dadurch sichergestellt, dass vom statistischen Fluorverteilungsmuster her jedenfalls auf der Oberseite des jeweiligen Kopfteils 20 sich kaum noch das Funktionsmedium in Form von Fluor befindet oder nur in sehr geringer Konzentration, wohingegen der Außenumfang der Stielteile 18 nach wie vor in hohem Maße die Fluorfunktionsgruppen aufweist. Summarisch betrachtet ist also die Außenumfangsseite des jeweiligen Kopfteils 20 aus dem gleitfähigen Kunststoffmaterial, vorzugsweise in Form von Polypropylen, gebildet, wohingegen der Außenumfang der Stielteile 18 das Fluor-Funktionsmedium aufweist, das insoweit die Friktion an den Stielteilen 18 erhöht, um dergestalt das Außereingriffbringen der korrespondierenden Haftverschlußteile 12,14 im Sinne einer Haftkrafterhöhung HK zu bewerkstelligen. Ebenso erlaubt die gleitende Kunststoffoberfläche für die Kopfteile, wie beschrieben, eine Erniedrigung der Schließkräfte SK, was besonders montagefreundlich ist.Since more or less the respective half of the closure loop 32 is used for the deformation of the stem parts 18 to the respective head part 20, the fluorine is also melted as functional medium with the extent, which leads to the fact that under fluorine influence the fluorine in the headers either volatilized or finely dispersed in the interior of the head part 20 is distributed statistically. Ultimately, however, this ensures that the statistical fluorine distribution pattern at least on the top of each head 20 hardly the functional medium is in the form of fluorine or only in very low concentration, whereas the outer periphery of the stem parts 18 still to a large extent the fluorine functional groups having. Summarily, therefore, the outer peripheral side of the respective head portion 20 of the lubricious plastic material, preferably in the form of polypropylene, formed, whereas the outer periphery of the stem parts 18, the fluorine functional medium, which increases the extent of the friction on the stem parts 18 so as to disengage the Corresponding adhesive closure parts 12,14 in the sense of a Haftkrafterhöhung HK to accomplish. Likewise, the sliding plastic surface allows for the headboards, as described, a lowering of the closing forces SK, which is particularly easy to install.

Da im vorliegenden Ausführungsbeispiel nach der Fig.2 das Trägerteil 16 aus einem Grundgewebe aus Kett- und Schußfäden bestehen soll, ist durch das Aufschneiden des Schlaufenmaterials grundsätzlich auch die Möglichkeit gegeben, dass das insoweit in das Trägerteil 16 eingewebte Schlaufenmaterial unter Krafteinwirkung an den Kopfteilen 20 herausgezogen wird. Durch das Aufbringen des Fluorfunktionsmediums auch in das Grundgewebe des Trägerteils 16 stehen reaktive Fluorgruppen im Trägerteil 16 zur Verfügung, die das Anhaften eines sog. Appreturmittels besonders erleichtern, das regelmäßig das Herausziehen der Verschlußelemente 22 deutlich erschwert und darüber hinaus kann das Appreturmittel (nicht dargestellt) von seinem Eigenschaften auch noch so modifiziert werden, beispielsweise flammhemmend ausgebildet werden, dass das so erzeugte Haftverschlußteil sich als besonders hitzeresistent erweist.As in the present embodiment according to the Fig.2 the support member 16 is to consist of a base fabric of warp and weft threads, by cutting the loop material in principle also given the possibility that the so far woven into the support member 16 loop material is pulled out under the action of force on the head parts 20. By applying the fluorine-functional medium into the base fabric of the carrier part 16, reactive fluorine groups are also available in the carrier part 16, which facilitate the adhesion of a so-called finishing agent, which regularly makes it considerably more difficult to pull out the closure elements 22 and, moreover, the finishing agent (not shown). be modified by its properties even as modified, for example flame retardant that the adhesive closure part thus produced proves to be particularly resistant to heat.

Anstelle von Fluor können auch andere Funktionsmedien, die sich als geeignet erweisen und die sich vorzugsweise gasförmig auftragen lassen, verwendet werden, wobei sich grundsätzlich Halogene als besonders geeignet erwiesen haben. Insbesondere gute Werte lassen sich erzielen, bei Einsatz von Chlorfluorid oder Chlortrifluorid als Funktionsmedium, die sich jedoch geringfügig teurer erweisen können als das vorliegend eingesetzte gasförmige Fluormaterial.Instead of fluorine, it is also possible to use other functional media which prove to be suitable and which can preferably be applied in gaseous form, with halogens in principle having proven to be particularly suitable. In particular, good values can be achieved when using chlorofluoride or chlorotrifluoride as the functional medium, which, however, may be slightly more expensive than the gaseous fluorine material used in the present case.

Eine weitere Möglichkeit der Verschlußherstellung ist in der WO 2007/036252 aufgezeigt, bei der sich auch in einen metallenen Grundkörper als Trägerteil 16 U-förmige Verschlußelemente krampenförmig einschießen lassen. Die für den Einschießvorgang modifizierten Festlegeteile können wiederum vorab mit dem Funktionsmedium versehen werden und anschließend erfolgt wiederum die Kopfteilbildung über ein thermisches Formgebungsverfahren, wie Flämmen oder mittels eines im Stand der Technik bekannten Walzen-Kalandrierverfahrens.Another possibility of closure production is in the WO 2007/036252 shown, in which 16 can also shoot in a metal base body as a support member U-shaped closure elements cramp-shaped. The fixing parts which have been modified for the insertion process can in turn be provided in advance with the functional medium and subsequently the formation of the head part takes place again via a thermal medium Shaping processes, such as scarfing or by means of a roll calendering process known in the art.

Es ist für einen Durchschnittsfachmann auf dem Gebiet der Haftverschlußtechnik überraschend, dass er durch gezieltes Anbringen von Funktionsgruppen, wie Fluorbestandteilen, an geometrisch oder räumlich verteilte Stellen am Haftverschlußteil in derart weit gezogenem Rahmen die Funktionsfähigkeit optimieren und einstellen kann.It is surprising for a person of ordinary skill in the field of adhesive fastener technology that he can optimize and adjust the functionality by selectively attaching functional groups, such as fluorine components, to geometrically or spatially distributed locations on the adhesive closure part in such a far drawn frame.
