Abstract
Description
Die Erfindung betrifft ein Haftverschlußteil, insbesondere für den Einsatz bei Schäumherstellverfahren, mit einem Trägerband mit auf diesem angeordneten Verhakungselementen sowie mit einem das Trägerband auf der von den Verhakungselementen abgewandten Seite überdeckenden Abdeckband, das breiter ist als das Trägerband, so daß sich freie Seitenrandbereiche des Abdeckbandes beidseits über die zugeordneten Längsränder des Trägerbandes hinaus erstrecken.The invention relates to an adhesive closure part, in particular for use in Schäumherstellverfahren, with a carrier tape with arranged on this Verhakungselementen and with a carrier tape on the of the Verhakungselementen averted side covering masking tape, the wider than the carrier tape, so that free side edge areas of the cover on both sides over the associated longitudinal edges of the carrier tape extend beyond.
Haftverschlüßteile dieser Art, bei denen sich an der Verhakungs- oder Vorderseite des Trägerbandes eine Vielzahl von einstückig ausgebildeten Ver hakungselementen in Form von Verdickungen aufweisenden Stengeln befindet, sind handelsüblich. Ein Herstellverfahren zum Herstellen des Trägerbandes solcher Haftverschlußteile ist in DE 198 28 856 C1 beschrieben. Bei diesem Verfahren wird ein thermoplastischer Kunststoff, insbesondere Polyolefin oder Polyamid, in plastischem oder flüssigem Zustand einem Spalt zwischen einem Druckwerkzeug und einem Formwerkzeug zugeführt, wobei als formgebendes Element am Formwerkzeug ein durchgehende Hohlräume aufweisendes Sieb verwendet wird und die Verhakungselemente dadurch gebildet werden, daß der thermoplastische Kunststoff in den Hohlräumen des Siebes zumindest teilweise erhärtet. Auf diese Weise wird ein sogenannter Mikrohaftverschluß mit 200 bis 400 Verhakungselementen pro cm2 ausgebildet. Anstelle der hierbei geformten pilzartigen Verhakungselemente kann auch ein Trägerband in Form eines textilen Materiales vorgesehen sein, bei dem die Verhakungselemente durch ein beispielsweise mit dem textilen Trägerband einstückiges Schlaufenmaterial gebildet sind. Anstelle des Schlaufenmaterials kann aber auch ein Flausch oder eine Filzstruktur verwendet werden.Haftverschlüßteile this type, in which at the Verhakungs- or front side of the carrier tape a plurality of integrally formed Ver hakungselementen in the form of thickened stems is commercially available. A manufacturing method for producing the carrier tape such adhesive closure parts is described in DE 198 28 856 C1. In this method, a thermoplastic plastic, in particular polyolefin or polyamide, supplied in a plastic or liquid state a gap between a pressure tool and a mold, wherein as a forming element on the mold a continuous cavities exhibiting sieve is used and the Verhakungselemente be formed by the thermoplastic material in the cavities of the screen at least partially hardens. In this way, a so-called micro-adhesion closure with 200 to 400 interlocking elements per cm 2 is formed. Instead of the mushroom-like hooking elements formed in this case, it is also possible to provide a carrier strip in the form of a textile material, in which the hooking elements are formed by a loop material which is integral with the textile carrier strip, for example. Instead of the loop material but also a loop or a felt structure can be used.
Derart hergestellte Haftverschlüsse werden vielfältig eingesetzt, beispielsweise in der Kraftfahrzeugtechnik, der Bodenverlegetechnik, für Bekleidung jedweder Art und für spezielle Anwendungen im Maschinenbau. Die Haftverschlüsse haben sich auf diesen Gebieten als eine lösbare und funktionssichere Verbindungs- und Verschlußtechnik bewährt.Adhesive closures produced in this way are used in a variety of ways, for example in automotive engineering, the floor laying technique, for clothing of any kind and for special applications in mechanical engineering. The adhesive closures have proven to be a solvable and reliable in these areas Connection and locking technology proven.
Sofern solche Haftverschlußteile für Flug- oder Fahrgastsitze eingesetzt werden, dienen sie dazu, Sitzbezüge an Schaumkörperteilen zu befestigen, wobei die einen Haftverschlußteile in das Polsterschaummaterial beim Herstellen des jeweiligen Sitzes mit eingeschäumt werden und das Haftverschlußteil mit den korrespondierenden Verhakungselementen am Polsterbezugsmaterial festgelegt, insbesondere festgenäht wird. Für die Herstellung der Schaumkörperteile werden die Haftverschlußteile in sogenannte Aufnahmepfeifen einer Einschäumform eingelegt, und durch Einbringen von Schaummaterial in die freien Querschnitte der Einschäumform, vorzugsweise von PU-Schaum, werden die Haftverschlußteile beim Einschäumvorgang an den Schaumkörperteilen befestigt. Die eingesetzten Pfeifen stehen in der Regel über die sonstigen Wandungen der Einschäumform vor und bilden so später im Schaumkörperteil nutartige Vertiefungen, in die der Polsterbezugsstoff mit dem anderen korrespondierenden Haftverschlußteil dann eingreift. Auf diese Art und Weise lassen sich Naht- und Formgeometrien am jeweiligen Sitz nachvollziehen. If such fastener parts used for air or passenger seats they serve to attach seat covers to foam body parts, wherein the one adhesive fastener parts in the pad foam material during manufacture the respective seat are foamed with and the adhesive closure part with the corresponding hooking elements on the upholstery material fixed, in particular sewn. For the production The foam body parts are the adhesive closure parts in so-called receiving pipes a foamed mold inserted, and by introducing Foam material in the free cross sections of the foam, preferably of PU foam, the fastener parts during the Einschäumvorgang attached to the foam body parts. The inserted pipes are in the rule about the other walls of the foam mold before and form so later in the foam body part groove-like depressions in the upholstery fabric with the other corresponding adhesive closure part then intervenes. In this way, seam and shape geometries can be at the respective seat.
Damit beim Ausschäumen der Einschäumform verhindert wird, daß Schaummaterial in den Bereich der Verhakungselemente eindringt, wodurch deren Verhakungswirkung zunichte gemacht würde, sind die für derartige Anwendungen handelsüblichen Haftverschlußteile an der den Verhakungselementen abgewandten Rückseite des Trägerbandes mit einem Abdeckband versehen, das breiter ist als das Trägerband, so daß freie Seitenrandbereiche des Abdeckbandes beidseits seitlich über das Trägerband vorstehen (z.B. entsprechend der nachveröffentlichten deutschen Patentanmeldung 199 56 011.0). Die vorstehenden Seitenrandbereiche dienen zur Bildung einer Schaumbarriere, indem diese Seitenrandbereiche an Formwänden der Einschäumform anliegen, die eine Formmulde umgeben, in der das Trägerband mit den Verhakungselementen aufgenommen ist. Durch Sichern des Haftverschlußteiles an der Wand der Einschäumform, was beispielsweise durch magnetische Fixierungsmittel erfolgen kann, wird durch das Anliegen der Seitenrandbereiche des überstehenden Abdeckbandes der Zutritt von Schaum in die die Verhakungselemente aufnehmende Formmulde verhindert.This is prevented during foaming of the foam mold, that Foam material penetrates into the region of the interlocking elements, whereby whose entanglement effect would be nullified are those for such Applications commercial adhesive fastener parts at the Verhakungselementen remote from the back of the carrier tape with a masking tape provided, which is wider than the carrier tape, so that free side edge areas of the masking tape protrude laterally on both sides of the carrier tape (e.g., according to the post-published German patent application 199 56 011.0). The protruding margin areas are for formation a foam barrier by these side edge areas on mold walls lie against the foam mold, which surround a mold cavity in which the Carrier tape is added with the hooking elements. By backing up the adhesive closure part on the wall of the foam mold, which, for example can be done by magnetic fixative is by the concern the side edge areas of the protruding cover strip of access of foam in the Verhakungselemente receiving mold cavity prevented.
Durch die US 4,784,890 ist ein gattungsgemäßes Haftverschlußteil bekannt, wobei bei der bekannten Lösung die freien Seitenrandbereiche des Abdeckbandes jeweils von einer Abdichtleiste überklebt sind. An den stirnseitigen Enden des bekannten Haftverschlußteils wird als Abdichthilfe ein klammerartiger Abdichtbogen zumindest mit der Unterseite des Trägerbandes klebend verbunden, die auf der abgekehrten Seite des Haftverschlußteils mit seinen Verhakungselementen verläuft. Die Herstellung dieses Haftverschlußteils ist zeit- und kostenintensiv, da erst separat bereitgestellte und zu fertigende Abdichtleisten mit dem Trägerband als Grundmaterial in klebender Weise zu verbinden sind. In Abhängigkeit des Herstellverfahrens kann auch nicht immer sichergestellt werden, daß die Klebstoffverbindung fest ist und eine sichere Abdichtung gewährleistet, so daß dem Schaummaterial gegebenenfalls eine hinreichende Angriffsfläche zur Verfügung steht, um die Abdichtung zu lösen, was zum Unbrauchbarwerden der Verhakungselemente führen kann.By the US 4,784,890 a generic fastener part is known wherein in the known solution, the free side edge regions of the cover strip each pasted over by a sealing strip. At the frontal Ends of the known adhesive closure part is used as a sealing aid clamp-like sealing arc at least with the underside of the carrier tape adhesively bonded, on the opposite side of the fastener part with its hooking elements runs. The production of this adhesive closure part is time consuming and expensive, since only separately provided and to be manufactured sealing strips with the carrier tape as base material in adhesive Way to connect. Depending on the manufacturing process can not always be ensured that the adhesive connection is firm and ensures a secure seal, so that the foam material if necessary, a sufficient attack surface is available, in order to release the seal, causing the Verhakungselemente become unusable can lead.
Durch die DE-U-90 13 133 ist es darüber hinaus bekannt, Haftverschtußteile zum Einschäumen in einen Schaumstoff-Formling auszubilden, wobei das Haftverschlußteil ein Abschnitt eines Haftbandes ist, das nur in einem über die ganze Länge des Haftbandes durchlaufenden Mittelstreifen zur Bildung eines von Längsrändern eingefaßten Haftverschlußstreifens mit Verhakungselementen besetzt ist. Bei der bekannten Lösung wird die ganze Vorderseite des Haftverschlußteils von einer Deckfolie bedeckt, die mindestens mit ihren Kanten mit den Kanten des Haftverschlußteils verbunden ist, wobei über den Längsrändern des Haftbandes zur Bildung von Halterändem magnetische Kunststoffstreifen befestigt sind. Aufgrund der mangelnden Abdichtwirkung der genannten magnetischen Kunststoffstreifen wird als Schutz für die Verhakungselemente von dem Schäummaterial die Abdeckfolie eingesetzt, deren Bereitstellung und Anbringen jedoch wiederum mit entsprechenden Herstellkosten verbunden ist. Auch muß in einem weiteren Arbeitsgang vor Wirksamwerden der Verhakungselemente die Deckfolie von dem Haftverschlußteil entfernt und entsorgt werden.By DE-U-90 13 133 it is also known Haftverschtußteile form for foaming in a foam molding, wherein the fastener part is a portion of an adhesive tape which is only in one over the entire length of the adhesive tape passing median stripe for Forming a bordered by longitudinal edges adhesive strip with Interlocking elements is occupied. In the known solution, the whole Front side of the fastener part covered by a cover sheet, the at least with its edges connected to the edges of the adhesive closure part, wherein over the longitudinal edges of the adhesive tape to form Halterändem magnetic plastic strips are attached. Due to the lack of Sealing effect of said magnetic plastic strip is called Protection for the entanglement of the foaming material the cover used, but their provision and attaching again with corresponding manufacturing costs is connected. Also, in another Operation before the Verhakungselemente effect the cover sheet be removed from the fastener part and disposed of.
Durch die US-A-4,710,414 ist ein weiteres gattungsgemäßes Haftverschlußteil bekannt, bei dem die auf einer Seite des Trägerbandes angeordneten Verhakungselemente als Schaumbarriere von einer folienartigen Abdeckhaube abgeschlossen sind. Auf der gegenüberliegenden Unterseite des Trägerbandes weist das Haftverschlußteil ein Abdeckband auf, das seitlich über die Folienabdeckung in der Einschäumform vorragt und dergestalt zusätzlich eine Abdichtung gegenüber dem Formschaum vornimmt. Trotz des plan verlaufenden Abdeckbandes und der zusätzlichen Abdeckhaube für die Verhakungselemente kann es aber nach wie vor ungewollt zu einem Schaummitteleintrag kommen und des weiteren ist der Herstellaufwand für die bekannte Lösung relativ hoch. Sollen die Verhakungselemente nach dem Formvorgang aus der Einschäumform entnommen einem Verhakungszweck zugeführt werden, ist die haubenartige Abdeckfolie zu entfernen und fällt somit zusätzlich als Abfallprodukt an.By US-A-4,710,414 is another generic adhesive closure member known in which arranged on one side of the carrier tape Verhakungselemente as a foam barrier of a film-like cover Are completed. On the opposite underside of the carrier tape the fastener part on a masking tape, the side over the film cover protrudes in the foam mold and in addition a seal against the foam forms. Despite the Plan extending cover band and the additional cover for but the hooking elements can still unintentionally become one Schaummitteleintrag come and further is the manufacturing effort for the known solution is relatively high. Should the Verhakungselemente after taken from the molding process from the Einschäumform a Verhakungszweck be supplied, the hood-like cover is to remove and thus falls in addition as a waste product.
Durch die US-A-5,766,385 ist es gemäß einem Teil der kennzeichnenden Merkmale des Patentanspruches 1 bekannt, ein folienartiges Abdeckband zum Abdecken der Verhakungselemente entlang ihrer Oberseite in Richtung auf das Trägerband hin längs einer in Längsrichtung verlaufenden Falzlinie über sich selbst umzufalten; die Faltung erfolgt jedoch an einer den Verhakungselementen zugewandten Seite, so daß die hiermit erzielte Dichtwirkung den praktischen Anforderungen nicht genügt. Zwar ist in der gezeigten bekannten Lösung nach der US - Entgegenhaltung das Verschlußelement selbst ferromagnetisch, um dergestalt die Verhaftung des Haftverschlußteils in der Einschäumform mit entsprechender Magnetkraft sicherzustellen; allein durch die aufgefaltete Dichtlippe des folienartigen Abdeckbandes und an der Oberseite der Verhakungselemente angeordnet, ist ein Eindringen des Schaummaterials eher begünstigt, denn abgehalten. Auch diese bekannte Lösung ist aufwendig und somit teuer in der Herstellung. Des weiteren ist nach dem Einschäumen wiederum die folienartige Abdeckung zu entfemen, um die Verhakungselemente zugänglich zu machen, was mit einer entsprechenden Abfallmenge bezogen auf das Abdeckband einhergeht. By US-A-5,766,385 it is according to a part of the characterizing Features of claim 1 known, a film-like masking tape for covering the hooking elements along their upper side in the direction on the carrier tape along a longitudinally extending fold line to fold over itself; However, the folding takes place at a Verhakungselementen facing side, so that the hereby achieved Sealing effect does not meet the practical requirements. Although in the the known solution according to the US - cited the closure element itself ferromagnetic, so as to arrest the Adhesive closure part in the foam mold with corresponding magnetic force ensure; solely by the unfolded sealing lip of the film-like Masking tape and arranged at the top of Verhakungselemente, is a penetration of the foam material rather favored, because held off. This known solution is complicated and therefore expensive to manufacture. Furthermore, after foaming, again, the foil-like Remove the cover to access the interlocking elements, what with a corresponding amount of waste based on the masking tape accompanied.
Ausgehend von diesem Stand der Technik stellt sich die Erfindung die Aufgabe, die bekannten Haftverschlußteile der oben erwähnten Art dahingehend zu optimieren; daß die durch die Seitenrandbereiche des Abdeckbandes gebildete Schaumbarriere eine absolut sichere Abdichtwirkung gewährleistet bei gleichzeitiger Reduzierung des Herstellaufwandes und möglicher Umweltbeeinträchtigung. Diese Aufgabe löst ein Haftverschlußteil mit den Merkmalen des Patentanspruches 1 in seiner Gesamtheit.Starting from this prior art, the invention has the task the known fastener parts of the type mentioned above to the effect to optimize; that through the side edge portions of the cover strip formed foam barrier ensures an absolutely secure sealing effect while reducing the manufacturing effort and possible Environmental impairment. This object solves a fastener part with the Features of claim 1 in its entirety.
Dadurch, daß erfindungsgemäß beide freien Seitenrandbereiche des Abdeckbandes in Richtung auf das Trägerband hin längs einer in Längsrichtung verlaufenden Falzlinie über sich selbst umgefaltet sind, so daß die Endränder der freien Seitenrandbereiche des Abdeckbandes den Längsrändern des Trägerbandes zugekehrt sind, und daß die Falzlinie eine Art Dichtlippe ausbildet, die zumindest eine nach außen in Richtung des jeweiligen Schaumes wirkende, in sich geschlossene Dichtfläche aufweist, erstreckt sich die Dichtlippe jeweils längs des die Verhakungselemente aufweisenden Bereiches, wobei die jeweilige Dichtlippe an den Wandteilen der Einschäumform anliegt, die die Formmulde umgeben, in der die Verhakungselemente während des Schäumvorganges aufgenommen sind. Durch das in die Einschäumform eingebrachte Schaummaterial wird diese Dichtlippe gegen die zugekehrten Wandteile der Form angedrückt, wobei die Dichtlippe sich aufgrund der gewissen Nachgiebigkeit im Bereich der Falzlinie an die die Dichtfläche bildenden Wandbereiche anschmiegt, so daß die Abdichtwirkung der Schaumbarriere gegenüber den bekannten Lösungen deutlich verbessert ist. Da darüber hinaus die Dichtlippe nach außen hin eine geschlossene Dichtfläche ausbildet, ist es nicht möglich, daß der Schaum in etwaige Kavitäten im bereich der Falzlinie zwischen die übereinanderliegenden Wandbereiche des Abdeckbandes eintritt, so daß mit der erfindungsgemäßen Lösung ein Versagensfall nahezu ausgeschlossen ist. Characterized in that according to the invention both free side edge regions of the cover strip in the direction of the carrier tape along a longitudinal direction extending fold line are folded over itself, so that the end edges the free side edge areas of the cover strip the longitudinal edges the carrier tape are facing, and that the fold line a kind of sealing lip that trains at least one outward towards the respective one Foam-acting, self-contained sealing surface extends the sealing lip in each case along the Verhakungselemente having Area, wherein the respective sealing lip on the wall parts of the foam mold is present, which surround the mold cavity in which the Verhakungselemente recorded during the foaming process. Through the in the foaming mold introduced foam material is this sealing lip pressed against the facing wall parts of the mold, wherein the sealing lip due to the certain flexibility in the fold line adheres to the sealing surface forming wall portions, so that the Sealing effect of the foam barrier over the known solutions is significantly improved. In addition, because the sealing lip to the outside forms a closed sealing surface, it is not possible that the Foam in possible cavities in the region of the fold line between the superimposed Wall portions of the cover strip occurs, so that with the solution according to the invention a failure case is almost impossible.
Dadurch, daß des weiteren erfindungsgemäß das Abdeckband ferromagnetische Eigenschaften aufweist, kann das Haftverschlußteil mit Hilfe einer magnetischen Halteeinrichtung an der Einschäumform in Stellung gehalten werden, beispielsweise durch Permanentmagnetleisten, die in der Einschäumform oder der Aufnahmepfeife der Einschäumform in Ausrichtung auf die Seitenrandbereiche des Deckbandes eingebettet sind.Characterized in that further according to the invention the cover band ferromagnetic Has properties, the adhesive closure part by means of a magnetic holding device held on the foam mold in position be, for example by permanent magnet strips that in the foam or the receiving whistle of the foam mold in alignment are embedded on the side edge portions of the shroud.
Da zum Herstellen der dahingehenden Dichtlippenfunktion keine weiteren Zusatz- oder Einsatzmaterialien notwendig sind, ist darüber hinaus die Herstellung vereinfacht, was sich wiederum günstig auf die Herstellkosten auswirkt. Da auf Zusatzmaterialien, insbesondere für die Abdeckung des eigentlichen Verschlußmaterials, verzichtet wird, ergibt sich auch kein Entsorgungsproblem für eine Abdeckfolie und die erfindungsgemäße Haftverschlußlösung ist somit als umweltfreundlich einzustufen.As for the production of the pertinent lip function no further Additional or feed materials are necessary, beyond the production simplified, which in turn has a favorable effect on the production costs. As on additional materials, especially for the cover of the actual Closure material, is omitted, there is no disposal problem for a cover film and the adhesive closure solution according to the invention is therefore classified as environmentally friendly.
Eine vorzugsweise Ausgestaltung des Haftverschlußteils ist dadurch charakterisiert, daß die Falzlinien die freien Seitenrandbereiche des Abdeckbandes in Teilbereiche unterteilen und daß die übereinanderliegenden Teilbereiche mit ihren einander zugewandten Seiten klebstofffrei in Anlage miteinander bringbar sind. Das erfindungsgemäße Haftverschlußteil kommt mithin für die Realisierung der jeweiligen Dichtlippenbereiche ohne Klebstoffeintrag aus, was zum einen die Herstellkosten reduziert und zum anderen der Umwelt zugute kommt, da auf einen lösemittelhaltigen Klebstoffzusatz verzichtet werden kann.A preferred embodiment of the adhesive closure part is characterized by that the fold lines the free side edge regions of the cover strip subdivide into subareas and that the superimposed subareas with their sides facing each other adhesive-free in contact with each other can be brought. The adhesive closure part according to the invention thus comes for the realization of the respective sealing lip areas without adhesive entry which reduces the manufacturing costs and the other Benefits the environment, since it dispenses with a solvent-based adhesive additive can be.
Bei einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen
Haftverschlußteils, das dadurch gekennzeichnet ist, daß die Teilbereiche
eines jeden Seitenrandbereiches gleich breit, insbesondere in Form gleicher
Hälften ausgebildet sind und daß die Endränder des jeweiligen Seitenrandbereiches
mit den Längsrändern des Trägerbandes im wesentlichen bündig
sind, ist erreicht, daß sich die Endränder des Abdeckbandes an den Längsrändern
des Trägerbandes abstützen können, so daß unter der anstehenden
Eindringwirkung des Schaumes sich die Dichtlippe nicht nach innen in
Richtung des Trägerbandes unbeabsichtigt zurückversetzen kann.
Vorzugsweise weist das Abdeckband ein Vlies mit eingebetteten ferromagnetischen
Partikeln auf, das über ein Verbindungsmittel mit der Seite
des Trägerbandes verbunden ist, die der die Verhakungselemente aufweisenden
Seite abgekehrt ist.
Das Verbindungsmittel kann aus einer Klebstoffschicht gebildet sein.In a further preferred embodiment of the adhesive closure part according to the invention, which is characterized in that the subregions of each side edge region are the same width, in particular in the form of identical halves and that the end edges of the respective side edge region are substantially flush with the longitudinal edges of the carrier tape is achieved, that the end edges of the cover strip can be supported on the longitudinal edges of the carrier tape, so that under the upcoming penetration effect of the foam, the sealing lip can not move back inwardly in the direction of the carrier tape unintentionally.
Preferably, the cover tape has a nonwoven with embedded ferromagnetic particles, which is connected via a connecting means with the side of the carrier tape, which has turned away from the hooking elements having the side.
The connecting means may be formed of an adhesive layer.
Um dem Haftverschlußteil eine gewisse Biegesteifigkeit zu verleihen, was
die Handhabung des Haftverschlußteiles beim Einlegen in die Einschäumform
erleichtert, und zwar insbesondere dann, wenn vorgegebene Längen
des Haftverschlußteiles in komplizierten dreidimensionalen Strukturen in
die betreffende Einschäumform eingelegt werden müssen, kann in die zwischen
Abdeckband und Trägerband befindliche Klebstoffschicht ein Versteifungsprofil
eingebettet sein. Hierbei kann es sich um einen Eisendraht handeln,
der gegen Korrosion mit einer Beschichtung versehen, insbesondere
verzinkt ist. Bei Verwendung eines ferromagnetischen Versteifungsdrahtes
kann dieser auch zur magnetischen Lagesicherung des Haftverschlußteiles
an der Einschäumform beitragen.
Die Verhakungselemente des erfindungsgemäßen Haftverschlußteiles können
aus Kunststoffmaterial, vorzugsweise aus Polyester, gebildet sein.
Die Verhakungselemente können aus haken- und/oder pilzartigen Verschlußkörpem
und/oder aus einem schlaufen- und/oder flauschartigen Verhakungsmaterial
gebildet sein. In order to give the fastener part a certain flexural rigidity, which facilitates the handling of the fastener part when inserting into the mold, in particular when predetermined lengths of the fastener part in complicated three-dimensional structures in the respective foam must be inserted, can in the between masking tape and carrier tape be located adhesive layer embedded a stiffening profile. This may be an iron wire, which is provided with a coating against corrosion, in particular galvanized. When using a ferromagnetic stiffening wire, this can also contribute to the magnetic position assurance of the adhesive closure part of the foaming mold.
The hooking elements of the adhesive closure part according to the invention can be made of plastic material, preferably of polyester.
The hooking elements can be formed from hook-shaped and / or mushroom-like closure bodies and / or from a loop-type and / or fleece-like hooking material.
Im folgenden wird eine Ausführungsform des erfindungsgemäßen Haftverschlußteiles anhand der Zeichnungen näher erläutert. Es zeigen in prinzipieller und nicht maßstäblicher Darstellung die

Das erfindungsgemäße Haftverschlußteil weist ein Trägerband 10 auf. Auf
der einen Seite des Trägerbandes 10 sind in Reihen nebeneinander und
hintereinander angeordnete Verhakungselemente 12 vorhanden. Beispielsweise
kann es sich bei dem Haftverschlußteil um einen sogenannten Mikrohaftverschluß
handeln, bei dem 200 bis 400 Verhakungselemente pro
cm2 an einem Trägerband 10 mit einer Dicke von 0,1 bis 0,3 mm vorgesehen
sind. Ein Verfahren zum Herstellen des Trägerbandes eines derartigen
Mikrohaftverschlusses ist in DE 198 28 856 C1 offenbart. Bei diesem bekannten
Verfahren wird ein thermoplastischer Kunststoff dem Spalt zwischen
einem Druckwerkzeug und einem Formwerkzeug zugeführt, bei dem
als formgebendes Element ein durchgehende Hohlräume aufweisendes Sieb
verwendet wird und bei dem die Verhakungselemente durch den in den
Hohlräumen des Siebes zumindest teilweise erhärtenden Kunststoff gebildet
werden. The adhesive closure part according to the invention has a
Das Trägerband 10 weist ein biegesteifes Versteifungsprofil auf, das sich
längs der gesamten Länge des Trägerbandes 10 erstreckt. Dieses Versteifungsprofil
besteht beim gezeigten Ausführungsbeispiel aus einem Draht
16, insbesondere in Form eines Metalldrahtes. Dieser Draht 16 ist über ein
als Ganzes mit 18 bezeichnetes Verbindungsmittel mit dem Trägerband 10
auf dessen den Verhakungselementen 12 abgewandten Rückseite verbunden.The
Als Verbindungsmittel 18 dient insbesondere eine Klebstoffschicht, in die
der Draht 16 eingebettet ist. Diese Klebstoffschicht kann beispielsweise aus
einem feuchtigkeitsvernetzenden PU bestehen. Das Verbindungsmittel 18
deckt vollständig die eine Seite des Trägerbandes 10 ab und ist mit diesem
fest verbunden. Die Durchmesserverhältnisse sind dabei derart gewählt,
daß die Dicke des Verbindungsmittels 18 in Form der Klebstoffschicht der
Dicke des Drahtes 16 entspricht Es wäre aber auch denkbar, daß das Verbindungsmittel
18 von seiner Dicke her den Draht 16 mit seinem vorgegebenen
Durchmesser nur teilweise aufnimmt.As a connecting
Das Verbindungsmittel 18 weist auf seiner dem Trägerband 10 abgewandten
Seite ein Abdeckband 20 in Form eines Textil- oder Kunststoffvlieses
auf. Das Abdeckband 20 steht seitlich entlang den Längsrändern 33 des
Trägerbandes 10 um einen vorgebbaren Abstand über, d.h. es wird beidseits
des Trägerbandes 10 jeweils ein freier Seitenrandbereich 21 des Abdeckbandes
20 gebildet, wobei dieser freie Seitenrandbereich 21 dazu vorgesehen
ist, an den Wandteilen 22 an der Oberseite einer Aufnahmepfeife
24 anzuliegen, die Bestandteil einer Einschäumform ist, die in der Fig. 1
nicht dargestellt ist. Die Aufnahmepfeife 24 weist eine Formmulde in Form
einer Ausnehmung 28 auf, wobei deren freier Querschnitt dem in dieser
Formmulde aufzunehmenden Trägerband 10 des Haftverschlußteiles mit
dessen Verhakungselementen 12 angepaßt ist. Die Verhakungselemente 12
kommen dabei in der Regel stirnseitig zur Anlage mit dem Grund der Ausnehmung
28.The connecting means 18 has on its the
Die freien Seitenrandbereiche 21 des Abdeckbandes 20 sind, wie dies aus
Fig. 1 ersichtlich ist, über sich selbst in Richtung auf die die Verhakungselemente
12 aufweisende Vorderseite, d.h. zu der der Aufnahmepfeife 24
zugekehrten Seite hin, umgefaltet, wobei sich die Falzlinien 29 jeweils in
Längsrichtung des Abdeckbandes 10 erstrecken und bei dem gezeigten Ausführungsbeispiel
mit den Seitenwänden 35 der Aufnahmepfeife 24 fluchten.
Bei an die Aufnahmepfeife 24 angelegtem Haftverschlußteil, wie es in Fig.1
dargestellt ist, liegt daher das Abdeckband 20 auf den Wandteilen 22, die
die Formmulde oder Ausnehmer 28 seitlich begrenzen, mit einer doppelten
Materiallage auf. Diese Doppellage des umgefalteten Abdeckbandes 20
ist durch zwei Teilbereiche 29a,b realisiert, die übereinanderliegend mit
ihren einander zugewandten Seiten vorzugsweise klebstofffrei in Anlage
miteinander bringbar sind. Die dahingehende Anlage wird unter der Wirkung
des Schaumes begünstigt, was der Abdichtung zugute kommt. Insbesondere
wirkt diese angesprochene Doppellage des umgefalteten Abdeckbandes
20 beim Schäumvorgang, d.h. beim Einfüllen des Schaummaterials
in die Einschäumform, wie eine Lippendichtung, die das Eindringen von
Schaummaterial in die Ausnehmung 28 verhindert, so daß die Verhakungselemente
12 des Trägerbandes 10, die in der Ausnehmung 28 aufgenommen
sind, gegen die Gefahr geschützt sind, von eindringendem Schaumaterial
verklebt zu werden.The free
Längs der Wandteile 22 der Aufnahmepfeife 24 sind Permanentmagnetleisten
30 oder eine Reihe von einzelnen Permanentmagneten angeordnet, die
zusammen mit der ferromagnetischen Eigenschaft des Abdeckbandes 20
eine magnetische Halteeinrichtung bilden, durch die die umgefalteten Seitenrandbereiche
21 des Abdeckbandes 20 und damit das Haftverschlußteil
an der Aufnahmepfeife 24 gesichert werden. Das Abdeckband 20, das vorzugsweise
aus einem Vlies, insbesondere aus Kunststoffmaterial, vorzugsweise
aus Polyester, gebildet ist, erhält seine ferromagnetische Eigenschaft
durch Einbetten von ferromagnetischen Partikeln in das Material des Abdeckbandes.
Die Verwendung eines Vlieses als Abdeckband ermöglicht
eine.gute Vernetzung mit dem Polyurethan-Formschaum, der für die Herstellung
von Polsterteilen für Fahrzeugsitze in die Einschäumform eingebracht
wird, so daß gewährleistet ist, daß die Haftverschlußteile durch das
Einschäumen sicher am Polsterteil verankert werden.Along the
