Description

Die Erfindung betrifft ein Haftverschlussteil mit den Merkmalen im Oberbegriff von Anspruch 1.The invention relates to an adhesive closure part having the features in the preamble of claim 1.

In WO 03/099951 A2 werden Verfahren zur Oberflächenmodifizierung eines Objekts angegeben, um die Adhäsionsfähigkeit des Objekts zu erhöhen, wobei die Oberfläche einer Strukturierung unterzogen wird, so dass eine Vielzahl von Vorsprüngen gebildet wird, die jeweils mit einem Fußteil und einem Kopfteil gebildet werden, wobei der Fußteil eine von der Oberfläche wegweisende Stirnfläche aufweist. Dabei wird jeder Vorsprung mit einer derartigen Größe gebildet, dass alle Stirnflächen die gleiche senkrechte Höhe über der Oberfläche besitzen und eine gemeinsame, durch gegenseitige Abstände zwischen den Stirnflächen unterbrochene Kontaktfläche bilden. Die Vorsprünge sind elastisch und relativ zur Oberfläche geneigt und aus einem Material gefertigt, dessen Elastizitätsmodul sich in wenigstens einer der Bezugsrichtungen verringert, die eine Längsrichtung jedes Vorsprungs vom Fußteil zum Kopfteil und eine Querrichtung jedes Vorsprungs axial von der Mitte des Fußteils nach außen umfassen. Teile der Kontaktfläche können mit einer geringeren Ablösekraft ausgestaltet sein, um ein erstes Aufbrechen der Haftverbindung zu erleichtern, während andere Teile eine stärkere Ablösekraft erfordern.In WO 03/099951 A2 For example, methods are disclosed for surface modification of an object in order to increase the adhesiveness of the object, wherein the surface is patterned to form a plurality of protrusions each formed with a foot portion and a head portion, the foot portion being one of Surface has pioneering face. In this case, each projection is formed with such a size that all end faces have the same vertical height above the surface and form a common, interrupted by mutual distances between the end faces contact surface. The protrusions are elastic and inclined relative to the surface and made of a material whose modulus of elasticity decreases in at least one of the reference directions comprising a longitudinal direction of each protrusion from the foot portion to the head portion and a transverse direction of each protrusion axially outward from the center of the foot portion. Portions of the contact surface may be configured with a lower peel force to facilitate initial breakage of the bond, while other portions require greater release force.

Kontaktflächen in der Größenordnung von 0,2 bis 0,5µm2 ermöglichen eine Wechselwirkung mit einem korrespondierenden weiteren Bauteil (Zweit-oder Drittbauteil), an dem das Haftverschlussteil festgelegt werden soll, über die sogenannten Van-der-Waals-Wechselwirkung, welche in klassischer Weise als Untergruppe der Adhäsion angesehen wird. Das bekannte Haftverschlussteil weist gute Verbindungseigenschaften auf, ist jedoch an ein aufwendiges und entsprechend kostenintensives Herstellverfahren gebunden. Aufgrund der relativ starren Anordnung zwischen dem typischerweise pilzförmigen Kopfteil und dem Trägerteil über ausschließlich geneigt angeordnete Stielteile ist noch Raum freigelassen für verbesserte Lösungen im Hinblick auf die Anhaft- und Ablöseeigenschaften des Haftverschlussteils bzw. der einzelnen Verschlussteile.Contact surfaces in the order of 0.2 to 0.5μm 2 allow interaction with a corresponding further component (second or third component) on which the adhesive closure part is to be determined, via the so-called Van der Waals interaction, which in classical Is regarded as a subgroup of adhesion. The known adhesive closure part has good connection properties, but is bound to a complicated and correspondingly cost-intensive production process. Due to the relatively rigid arrangement between the typically mushroom-shaped head part and the support part via exclusively inclined arranged stem parts is still room left for improved solutions in terms of adhesion and AblöSigenschaften the adhesive closure part or the individual closure parts.

Aus der DE 10 2008 027 860 A1 geht ein Haftverschlussteil hervor, umfassend ein Trägerteil und darauf aufstehend angeordnete Verschlussteile mindestens einer Art, die jeweils ein Kopfteil aufweisen, das an seiner freien Stirnseite zumindest eine Kontaktfläche zur wieder lösbaren Anhaftung an ein weiteres Bauteil aufgrund von Verhakung aufweist, wobei randseitig an zumindest eines der Kopfteile anschließend mindestens ein Anschlussabschnitt vorhanden ist, der über den Rand des genannten Kopfteils in mindestens einer Richtung derart vorsteht, dass es zu einer Veränderung der Größe für das entsprechende Kopfteil kommt.
In der DE 10 2006 024 014 A1 und der WO 2005/087033 A1 werden weitere Haftverschlussteile offenbart, deren Köpfe rund ausgebildet sind und die sich in der Dicke radial nach außen hin verjüngen können.From the DE 10 2008 027 860 A1 is an adhesive closure part, comprising a support member and arranged thereon closure parts of at least one type, each having a head portion having at its free end face at least one contact surface for releasable adhesion to another component due to entanglement, wherein edge on at least one of Headboards then at least one connection portion is present, which projects beyond the edge of said head portion in at least one direction such that there is a change in size for the corresponding head part.
In the DE 10 2006 024 014 A1 and the WO 2005/087033 A1 further Haftverschlussteile be revealed, the heads are round and can taper in thickness radially outward.

Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Aufgabe, die Anhaft- und Ablöseeigenschaften des Haftverschlussteils an einem Zweit- oder Drittbauteil zu verbessern, wobei allzu große Belastungen und Beschädigungen der Verschlussteile vermieden werden sollen.Based on this prior art, the invention has the object to improve the adhesion and detachment properties of the adhesive closure part on a second or third component, with excessive loads and damage to the closure parts to be avoided.

Diese Aufgabe wird gelöst durch ein Haftverschlussteil mit den Merkmalen des Patentanspruchs 1 in seiner Gesamtheit.This object is achieved by an adhesive closure part having the features of patent claim 1 in its entirety.

Es ist erfindungsgemäß vorgesehen, dass mehrere, mindestens zwei, Anschlussabschnitte regelmäßig am jeweiligen Kopfteil ausgebildet sind.It is inventively provided that a plurality, at least two, terminal portions are formed regularly on the respective head part.

Dadurch, dass randseitig an mindestens eines der Kopfteile anschließend mindestens ein Anschlussabschnitt vorhanden ist, der über den Rand des genannten Kopfteils in mindestens einer Richtung derart vorsteht, dass es zu einer Veränderung der wirksamen Größe der Kontaktfläche für das entsprechende Kopfteil kommt, wird die Kontaktfläche des zumindest einen Kopfteils derart modifiziert, dass sie vergrößert oder verkleinert ist und an dem mindestens einen Anschlussabschnitt zumindest eine Abrisskante definiert wird, welche ein Ablösen der Kontaktfläche von einem Zweit- oder Drittbauteil erleichtert. Zweckmäßigerweise führt der mindestens eine Anschlussabschnitt zu einer Vergrößerung der entsprechenden Kontaktfläche, besonders bevorzugt steht die komplette Fläche des mindestens einen Anschlussabschnitts als zusätzliche Kontaktfläche zur Verfügung.Due to the fact that at least one connecting section is present on the edge side of at least one of the head parts and protrudes beyond the edge of said head part in at least one direction in such a way that the effective size of the contact surface for the corresponding head part is changed at least one head part modified in such a way that it is enlarged or reduced and at the at least one connecting portion at least one tear-off edge is defined, which facilitates detachment of the contact surface of a second or third component. Expediently, the at least one connection section leads to an enlargement of the corresponding contact surface, particularly preferably the complete surface of the at least one connection section is available as an additional contact surface.

Randseitiger Anschluss im Sinne der Erfindung meint, dass der mindestens eine Anschlussabschnitt in einem Randbereich an das jeweilige Kopfteil angebunden wird. Dies kann beispielsweise ein stirnseitiger Randabschnitt der Kontaktfläche sein, jedoch auch ein unmittelbar oder mittelbar an die Kontaktfläche anschließender Seitenabschnitt des jeweiligen Kopfteils sein. Zweckmäßigerweise ist der mindestens eine Anschlussabschnitt in einem stirnseitigen Randbereich an das jeweilige Kopfteil angebunden. Typischerweise ist das entsprechende Kopfteil pilzförmig ausgebildet und verjüngt sich vom stirnseitigen Randbereich in Richtung des Trägerteils, genauer in Richtung eines das jeweilige Kopfteil mit dem Trägerteil verbindenden Stielteils.Edge-side connection according to the invention means that the at least one connection section is connected in an edge region to the respective head part. This may, for example, be an end-side edge section of the contact surface, but also a side section of the respective head section which adjoins the contact surface directly or indirectly. Conveniently, the at least one connection section is connected in a front-side edge region to the respective head part. Typically, the corresponding head part is mushroom-shaped and tapers from the front-side edge region in the direction of the support part, more precisely in the direction of a connecting the respective head part with the support member stem part.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Haftverschlussteils erstreckt sich der mindestens eine Anschlussabschnitt in Richtung der Erstreckung der jeweiligen Kontaktfläche. Bei dieser Anordnung führt der mindestens eine Anschlussabschnitt zu einer Verbreiterung der jeweiligen Kontaktfläche in Richtung der jeweiligen Erstreckung, besonders bevorzugt schließt sich der jeweilige Anschlussabschnitt in Erstreckungsrichtung unmittelbar an die jeweilige Kontaktfläche an. Es ist jedoch auch denkbar, dass der jeweilige Anschlussabschnitt von der Kontaktfläche beabstandet und/oder nicht an einen unmittelbar an die jeweilige Kontaktfläche angrenzenden stirnseitigen Randbereich des jeweiligen Kopfteils angebunden ist. Bei derartigen Ausgestaltungen entsteht eine höhere Flexibilität der gesamten Kontaktfläche, da die stirnseitige Kontaktfläche und der jeweilige Anschlussabschnitt in unterschiedlichen Winkellagen an ein Drittbauteil angebunden und mit diesem eine Adhäsionsverbindung eingehen können. Zweckmäßigerweise weist mindestens ein Anschlussabschnitt entlang seiner Erstreckung Bereiche unterschiedlicher Breite und/oder Dicke auf, insbesondere eine zum freien Rand abnehmende Dicke. Auf diese Weise entstehen am Rand des mindestens einen Anschlussabschnitts bzw. der jeweiligen Kontaktfläche gute anleg- und ablösbare Randabschnitte vergleichbar einer dünnen Lippe. Weiter ist es vorteilhaft, den mindestens einen Anschlussabschnitt aus dem gleichen Material wie das jeweilige Kopfteil auszubilden, insbesondere an dieses anzuformen. Zudem können der mindestens eine Anschlussabschnitt und/oder das entsprechende Kopfteil ein eigenständiges, mit dem entsprechenden Kopfteil bzw. Verschlussteil verbindbares Bauteil sein. Hieraus ergibt sich der Vorteil, dass die jeweiligen Anschlussabschnitte und/oder Kopfteile unabhängig vom weiteren Haftverschlussteil gefertigt werden können und entsprechend einem jeweiligen Einsatzzweck mit dem Verschlussteil verbunden bzw. auf dieses aufgesetzt werden können. Zur Ausgestaltung bestimmter Eigenschaften der Anschlussabschnitte kann ein anderes Material im Gegensatz zu den für die übrigen Verschlussteile verwendeten Materialien gewählt werden, insbesondere ein Material mit guten Elastizitäts- und Adhäsionseigenschaften.In a preferred embodiment of the adhesive closure part according to the invention, the at least one connection section extends in the direction of the extent of the respective contact surface. In this arrangement, the at least one connection section leads to a broadening of the respective contact surface in the direction of the respective extent, particularly preferably, the respective connection section connects in the extension direction directly to the respective contact surface. However, it is also conceivable that the respective connection portion is spaced from the contact surface and / or is not connected to an immediately adjacent to the respective contact surface frontal edge region of the respective head part. In such embodiments, a higher flexibility of the entire contact surface, since the frontal contact surface and the respective connection portion connected in different angular positions to a third component and can enter into this with an adhesion connection. Expediently, at least one connecting section has areas of different width and / or thickness along its extent, in particular a thickness decreasing towards the free edge. In this way, on the edge of the at least one connecting section or the respective contact surface, good edge segments that can be applied and removed are formed, comparable to a thin lip. Further, it is advantageous to form the at least one connecting portion made of the same material as the respective head part, in particular to mold this. In addition, the at least one connection section and / or the corresponding head part can be an independent component that can be connected to the corresponding head part or closure part. This results in the advantage that the respective connection sections and / or head parts can be manufactured independently of the further adhesive closure part and can be connected to the closure part or placed thereon in accordance with a respective intended use. For the design of certain properties of the connection sections, another material, in contrast to those for the other materials used are used, in particular a material with good elasticity and adhesion properties.

Mindestens ein Anschlussabschnitt ist bevorzugt als Zahn, Zacke und/oder Lasche ausgebildet. Die Zähne, Zacken und/oder Laschen können durch Anformung des mindestens einen Anschlussabschnittes an das Kopfteil ausgebildet werden oder durch Einbringen von Einschnitten bzw. Ausnehmungen am jeweiligen Kopfteil. Bei einer derartigen Ausbildung des mindestens einen Anschlussabschnitts werden randseitig angeordnete Abrisskanten in definierter Weise festgelegt. Zweckmäßigerweise weisen die Zähne, Zacken und/oder Laschen jeweils eine dreieckförmige Form auf. Weiter kann mindestens ein Anschlussabschnitt kammartig und/oder wellenförmig ausgebildet sein. Auch ein sinusförmiger Verlauf des freien Anschlussabschnittrandes ist denkbar. Es können jeweils gleichartige oder unterschiedliche Anschlussabschnitte an einem Kopfteil vorgesehen sein.At least one connection section is preferably designed as a tooth, a prong and / or a tab. The teeth, teeth and / or tabs can be formed by molding the at least one connection section to the head part or by introducing incisions or recesses on the respective head part. In such a design of the at least one connecting portion edge edges arranged demolition edges are defined in a defined manner. Conveniently, the teeth, teeth and / or tabs each have a triangular shape. Furthermore, at least one connection section can be comb-like and / or wave-shaped. A sinusoidal profile of the free terminal section edge is also conceivable. It can be provided on a headboard respectively similar or different connection sections.

an apparatus for carrying out a method for producing a Haftverschlussteils invention.

Fig. 1 zeigt einen Abschnitt eines Haftverschlussteils 10 mit einem Trägerteil 12, auf welchem Verschlussteile 20a-20i angeordnet sind, von welchen jeweils ein Kopfteil 14a-14i sichtbar ist. Die Kopfteile 14a-14i weisen jeweils randseitig angeordnete Anschlussabschnitte 16a-16i auf und erhalten durch deren regelmäßige Anordnung einen rosettenartigen Außenrand. Des weiteren ist jedes Kopfteil 14a-14i und das entsprechende Verschlussteil 20a-20i rotationssymmetrisch zum jeweiligen Mittelpunkt 18a-18i ausgebildet. Hieraus ergibt sich der Vorteil von in sämtliche radiale Richtungen gleichen Eigenschaften des jeweiligen Kopfteils 14a-14i bzw. Verschlussteils 20a-20i. Die maximale radiale Erstreckung da-di der jeweiligen Kopfteile 14a-14i beträgt jeweils ca. 40µm. Im gezeigten Ausführungsbeispiel sind in einem Flächenabschnitt von 200µm x 200µm ca. zwölf Verschlussteile 20a-20i angeordnet. Aus der gleichförmigen Ausbildung und Anordnung der einzelnen Verschlussteile 20a-20i ergeben sich homogene Eigenschaften des Haftverschlussteils 10. Fig. 1 shows a portion of a fastener closure part 10 with a support part 12, on which closure parts 20a-20i are arranged, from each of which a head part 14a-14i is visible. The head portions 14a-14i each have edge portions arranged on connecting portions 16a-16i and obtained by their regular arrangement a rosette-like outer edge. Furthermore, each head part 14a-14i and the corresponding closure part 20a-20i are rotationally symmetrical to the respective center 18a-18i. This results in the advantage of the same properties of the respective head part 14a-14i or closure part 20a-20i in all radial directions. The maximum radial extent d a -d i of the respective head portions 14a-14i is approximately 40 μm each. In the exemplary embodiment shown, approximately twelve closure parts 20a-20i are arranged in a surface section of 200 μm x 200 μm. Homogeneous properties of the adhesive closure part 10 result from the uniform design and arrangement of the individual closure parts 20a-20i.

In Fig. 2a ist das Verschlussteil 20a bzw. das Kopfteil 14a vergrößert dargestellt. An der gezeigten Stirnfläche legt das Kopfteil 14a eine Kontaktfläche 22a fest, welche im Wesentlichen kreisförmig mit Durchmesser DK ausgebildet ist, wie mit Kreislinie 26a angedeutet. Eine innere Kreislinie 26i deutet die radiale Erstreckung Ds des Stielteils 24 an. Die Kontaktfläche 22a wird durch die Anschlussabschnitte 16a vergrößert, welche als regelmäßig entlang der äußeren Kreislinie 26a angeordnete Zähne 28 ausgebildet sind.In Fig. 2a the closure part 20a or the head part 14a is shown enlarged. At the end face shown, the head part 14a defines a contact surface 22a, which is formed substantially circularly with diameter D K , as indicated by circle line 26a. An inner circle 26i indicates the radial extent Ds of the stem part 24. The contact surface 22a is enlarged by the connecting portions 16a, which are formed as regularly arranged along the outer circular line 26a teeth 28.

Eine alternative Ausgestaltung von an einem Kopfteil 14' angeordneten Anschlussabschnitten 16' ist in Fig. 2b gezeigt. Die Anschlussabschnitte 16' sind als sich abwechselnde Zähne 28' und Laschen 32 ausgebildet. Die Zähne 28' sind jeweils dreieckförmig und in radialer Richtung 30 spitz zulaufend ausgebildet und weisen gegenüber den rechteckförmigen Laschen 32 eine größere Erstreckung in radialer Richtung 30 auf, hingegen entlang der äußeren Kreislinie 26a eine geringere Erstreckung. Auch in der in Fig.2b gezeigten Ausgestaltung führen die sich in radialer Richtung 30 unmittelbar an die Kontaktfläche 22' anschließenden Anschlussabschnitte 16' in Form der Zähne 18' und Laschen 32 zu einer Kontaktflächenvergrößerung.An alternative embodiment of connecting portions 16 'arranged on a head part 14' is shown in FIG Fig. 2b shown. The terminal portions 16 'are formed as alternating teeth 28' and tabs 32. The teeth 28 'are each triangular and tapered in the radial direction 30 and have over the rectangular tabs 32 a greater extent in the radial direction 30, however, along the outer circular line 26 a smaller extension. Also in the in 2b The embodiment shown in the radial direction 30 directly to the contact surface 22 'subsequent connecting portions 16' in the form of teeth 18 'and tabs 32 lead to a contact surface enlargement.

In Fig. 2c ist eine dem Verlauf eines N-Ecks, hier eines Sechsecks, folgende Randkontur einer Kontaktfläche 22" gezeigt. An ein pilzförmiges Kopfteil 14" sind sechs gleichförmige Anschlussabschnitte 16" in Form von dreieckförmigen Zähnen 28" angeformt, wodurch die genannte sechseckförmige Randkontur der Kontaktfläche 22" ausgebildet wird.In Fig. 2c a contour of an N-shaped corner, here a hexagon, is shown following a contour surface of a contact surface 22 ", a six-shaped connecting portion 16" in the form of triangular teeth 28 "are formed on a mushroom-shaped head portion 14", whereby said hexagonal edge contour of the contact surface 22 "is trained.

Fig. 2d zeigt eine Kontaktfläche 22"', deren Größe durch sich an den Rand der dreieckförmigen Kontaktfläche 22"' bzw. des Kopfteils 14" anschließende Laschen 32'" und Kammabschnitte 34 vergrößert wird. Die drei Kammabschnitte 34 sind entlang der Seiten des gleichseitigen Dreiecks, die Laschen 32'" an den drei Ecken des gleichseitigen Dreiecks angeordnet. Aus Fig. 2d gut erkennbar ist, dass die Form des Kopfteiles 14'" nicht auf einen Pilz, d.h., eine runde Form beschränkt ist, sondern ebenfalls eine eckige Form aufweisen kann. Fig. 2d shows a contact surface 22 "', whose size is increased by itself to the edge of the triangular contact surface 22"' and the head part 14 "subsequent tabs 32 '" and comb portions 34. The three comb portions 34 are arranged along the sides of the equilateral triangle, the tabs 32 '"at the three corners of the equilateral triangle Fig. 2d It will be appreciated that the shape of the head portion 14 '"is not limited to a mushroom, ie, a round shape, but may also have a polygonal shape.

Fig. 3 zeigt einen Längsschnitt durch die in Fig. 1 gezeigten Verschlussteile 20a, 20b des Haftverschlussteils 10. Die Verschlussteile 20a, 20b stehen im Wesentlichen senkrecht auf dem Trägerteil 12 auf und die an den Kopfteilen 14a, 14b ausgebildeten Kontaktflächen 22a, 22b erstrecken sich jeweils im Wesentlichen parallel zum Trägerteil 12 und darüber hinaus in einer vom Trägerteil 12 mit dem gleichen Abstand x3 beabstandeten Ebene. Die beiden Verschlussteile 20a, 20b unterscheiden sich dadurch, dass das Stielteil 24a vom Kopfteil 14a zum Trägerteil 12 verlaufend im Wesentlichen die gleiche Dicke Ds aufweist, wohingegen das Stielteil 24b eine Verjüngung y2 und eine Verbreiterung y3 aufweist. Die am Kopfteil 14a randseitig sich anschließenden Anschlussabschnitte 16a erstrecken sich entsprechend der Kontaktfläche 22a in radialer Richtung 30 und vergrößern in unmittelbarem Anschluss die Kontaktfläche 22a. Fig. 3 shows a longitudinal section through the in Fig. 1 The closure parts 20a, 20b are substantially perpendicular to the carrier part 12 and the contact surfaces 22a, 22b formed on the head parts 14a, 14b extend in each case substantially parallel to the carrier part 12 and furthermore in one from the support member 12 at the same distance x 3 spaced plane. The two closure parts 20a, 20b differ in that the stem part 24a has essentially the same thickness Ds running from the head part 14a to the carrier part 12, whereas the stem part 24b has a taper y 2 and a broadening y 3 . The edge portions 14a adjoining the edge portions 16a extend correspondingly the contact surface 22a in the radial direction 30 and enlarge the contact surface 22a in immediate connection.

Im Gegensatz dazu sind die am Kopfteil 14b vorgesehenen Anschlussabschnitte 16b quer zur radialen Richtung 30 und zur axialen Richtung 36 gerichtet. Die durch die Anschlussabschnitte 16b vergrößerte Kontaktfläche 22b weist stirnseitig in radialer Richtung 30 ausgerichtete Flächenbereiche und quer zur Radialrichtung 30 ausgerichtete Flächenbereiche auf. Aus Fig. 3 gut erkennbar ist, dass die jeweiligen Anschlussabschnitte 16a-16b dünnlippig ausgebildet sind und eine zum freien Rand abnehmende Dicke aufweisen. Es sind aber auch Lösungsvarianten denkbar, bei denen der jeweilige Anschlußabschnitt sich mit gleichbleibender Dicke bzw. Materialstärke an den freien Außenrand des zuordenbaren Kopfteils anschließt, ohne sich nach außen hin lippenartig zu verjüngen, was insoweit zu einer vorteilhaften Abstützung der insoweit bereits erläuterten Abrißkante oder Abrißlinie führt. Die gezeigte Rotationssymmetrie der Verschlussteile 20a und 20b ist zweckmäßig hinsichtlich rotationsinvarianter Eigenschaften.In contrast, the terminal portions 16b provided on the head portion 14b are directed transversely to the radial direction 30 and the axial direction 36. The enlarged by the terminal portions 16b contact surface 22b has frontally in the radial direction 30 aligned surface areas and transverse to the radial direction 30 aligned surface areas. Out Fig. 3 It can be clearly seen that the respective connection sections 16a-16b have a thin-lipped design and have a thickness that decreases toward the free edge. But there are also possible solution variants in which the respective terminal portion adjoins the free outer edge of the assignable head part with constant thickness or material thickness, without tapering lip-like to the outside, which in this respect to an advantageous support of the extent already explained tear-off or tear leads. The shown rotational symmetry of the closure parts 20a and 20b is expedient with regard to rotationally invariant properties.

In Fig. 4 ist das Verfahren zur Herstellung des Haftverschlussteil 10 veranschaulicht. Aus einem Extruderkopf 40 extrudiertes Kunststoffmaterial wird zwischen eine Druckwalze 42 und eine Formwalze 44 geführt. Die Druckwalze 42 bewegt sich in eine erste Bewegungsrichtung 46, die Formwalze 44 in eine der ersten Bewegungsrichtung 46 entgegensetzten zweiten Bewegungsrichtung 48. Die Formwalze 44 ist mantelseitig mit einem Formsieb 50 versehen, in welchem entsprechend der auszubildenden Verschlussteile 20 Formhohlräume 52 ausgebildet sind. An einer Innenseite 54 sind die Formhohlräume 52 entsprechend den Kopfteilen 14a-14c und den an diesen vorgesehenen Anschlussabschnitten ausgebildet. Durch die Rotationsbewegung der beiden Walzen 42, 44 wird das in einen von diesen ausgebildeten Spalt eingeführte Kunststoffmaterial in die Formhohlräume 52 des Formsiebs 50 gedrückt und auf der der Formwalze 44 zugeordneten Seite des Trägerteils 12 aus Kunststoffmaterial Verschlussteile 20 ausgebildet. Nach Aushärten und Entformen bzw. Ausführen der Verschlussteile 20 aus den entsprechenden Formhohlräumen 52 steht ein unmittelbar einsatzbereites Haftverschlussteil 10 umfassend ein Trägerteil 12 und darauf aufstehend angeordnete Verschlussteile 20, 20' mit Kopfteilen 14,14' bereit. Das Formsieb 50 hat dann von der freien Stirnseite her betrachtet Formausnehmungen, wie sie beispielhaft in der Fig.1 für eine ausgeführte Kopfform des Endproduktes dargestellt sind. Anstelle eines Extrusionsverfahrens unter bevorzugter Verwendung von thermoplastischen Kunststoffen können auch Zwei- oder Mehrkomponentenmischungen unter Verwendung von Formkavitäten verarbeitet werden, wie beispielsweise Polyvinylsiloxan.In Fig. 4 the method of making the adhesive fastener 10 is illustrated. Plastic material extruded from an extruder head 40 is passed between a pressure roll 42 and a forming roll 44. The pressure roller 42 moves in a first direction of movement 46, the forming roller 44 in a first direction of movement 46 opposite second direction of movement 48. The forming roller 44 is provided on the shell side with a forming wire 50, in which corresponding to the trainees shutter 20 form cavities 52 are formed. On an inner side 54, the mold cavities 52 are formed corresponding to the head portions 14a-14c and the terminal portions provided thereon. As a result of the rotational movement of the two rollers 42, 44, the plastic material introduced into a gap formed by them is pressed into the mold cavities 52 of the forming wire 50 and assigned to the mold roller 44 Side of the carrier part 12 made of plastic material closure parts 20 is formed. After curing and removal or execution of the closure parts 20 from the corresponding mold cavities 52 is an immediately ready adhesive fastener part 10 comprising a support member 12 and thereon arranged upright closure parts 20, 20 'with headboards 14,14' ready. The forming wire 50 has then seen from the free end side mold cavities, as exemplified in the Fig.1 are shown for an executed head shape of the final product. Instead of an extrusion process with the preferred use of thermoplastics, two- or multi-component mixtures can also be processed using mold cavities, such as polyvinylsiloxane.

In vorteilhafter Weise ist das Trägerteil 12 einstückig mit den Verschlussteilen 20, 20' ausgebildet. Des Weiteren kann das jeweilige Kunststoffmaterial mittels eines Mikro-Replikationsverfahrens verarbeitet werden. Weitere Verfahren zur Herstellung des Haftverschlussteils bzw. der Verschlussteile 20 sind neben dem Chill-, Roll-Verfahren, Mikro- oder Nanolithographieverfahren, einschließlich des sogenannten Mikro-Printing. Jedenfalls läßt sich die aufgezeigte Mikrostruktur auch mittels einer Art Kristallwachstum erreichen. Im übrigen läßt sich das Verschlussmaterial auch aus dem Vollen generieren, beispielsweise unter Einsatz von Mikro-Funkenerosion oder entsprechender Laserstrahlbearbeitung.Advantageously, the support member 12 is formed integrally with the closure parts 20, 20 '. Furthermore, the respective plastic material can be processed by means of a micro-replication method. Further methods for producing the adhesive closure part or the closure parts 20 are, in addition to the chill, roll method, micro or nanolithography method, including the so-called micro-printing. In any case, the indicated microstructure can also be achieved by means of a kind of crystal growth. Moreover, the closure material can also be generated from the solid, for example by using micro-spark erosion or appropriate laser beam processing.

Erfindungsgemäß können zudem die Verschlussteile 20, 20a-20i gesondert gefertigt, bevorratet und/oder transportiert werden und anforderungsgemäß mit einem entsprechenden Trägerteil 12 verbunden bzw. auf diesem angeordnet werden. Insbesondere können Verschlussteile unterschiedlicher Art, beispielsweise erfindungsgemäß modifizierte Adhäsionsverschlussteile, Verhakungsteile und/oder Schlaufenteile, auf einem Trägerteil 12 angeordnet werden. Je nach Anwendungsfall können weitere Funktionselemente am Trägerteil 12 vorgesehen werden, insbesondere können die Verschlussteile auf einem oder auf beiden Seiten des Trägerteils 12 angeordnet werden. According to the invention, moreover, the closure parts 20, 20a-20i can be manufactured separately, stored and / or transported and, as required, connected to a corresponding carrier part 12 or arranged on it. In particular, closure parts of different types, for example, according to the invention, modified adhesion closure parts, hooking parts and / or loop parts, can be arranged on a carrier part 12. Depending on the application, further functional elements can be provided on the carrier part 12, in particular the closure parts be arranged on one or both sides of the support member 12.
