Description

Die Erfindung betrifft ein Skifell für Skis, mit einer Tragschicht, die an einer Aussenseite eine Fellschicht und an einer Innenseite eine Klebeschicht aufweist, mit welcher das Skifell lösbar auf dem Ski befestigt werden kann. Die Erfindung betrifft zudem ein Verfahren zum Herstellen eines solchen Skifells.The invention relates to a skimmer for skis, having a base layer which has a skin layer on one outer side and an adhesive layer on an inner side, with which the ski skin can be detachably fastened on the ski. The invention also relates to a method for producing such a ski.

Skifelle sind insbesondere als Steigfelle für Skis seit langem bekannt. Diese Skifelle weisen eine Tragschicht aus einem Gewebe oder einer Folie auf. Auf einer Aussenseite der Tragschicht ist eine Fellschicht angeordnet, die eine Vielzahl von Haaren aufweist, die in Laufrichtung gesehen nach hinten gerichtet sind. Die Fellschicht verhindert ein Zurückrutschen des Skis bei ansteigendem Gelände. Solche Fellschichten bestehen üblicherweise aus künstlichen Materialien.Skins have long been known as skins for skis. These skins have a base layer of a fabric or a foil. On an outside of the base layer, a skin layer is arranged, which has a plurality of hairs, which are directed towards the rear in the running direction. The fur layer prevents the ski from slipping back when the terrain is rising. Such fur layers are usually made of artificial materials.

Auf einer Innenseite der Tragschicht ist üblicherweise eine Klebschicht aufgetragen, die es ermöglicht, das Skifell über die gesamte Länge des Skis lösbar zu befestigen. In der Regel ist am vorderen Ende des Skifells noch ein Beschlag angeordnet, mit dem das Skifell an der Skispitze mechanisch befestigt werden kann. Möglich ist auch ein Beschlag am hinteren Ende des Skifells.On an inner side of the base layer, an adhesive layer is usually applied, which makes it possible to releasably secure the ski skin over the entire length of the ski. As a rule, a fitting is arranged at the front end of the skinning, with which the ski skin can be mechanically attached to the ski tip. Also possible is a fitting at the rear end of the ski skin.

Bei der Verwendung von Haftklebern zum Befestigen des Skifells am Ski, bestehen seit langem die folgenden Schwierigkeiten:When using pressure-sensitive adhesives to attach the ski to the ski, the following difficulties have long existed:

Bei den bisher verwendeten Klebern lässt bei tiefen Temperaturen die Haftung des Skifells am Ski wesentlich nach. Dies führt häufig zum Abfallen der Skifelle auf Skitouren bei besonders kalten Bedingungen und insbesondere nach mehrmaligem Auffellen derselben Tour.In the case of the adhesives used hitherto, the adhesion of the ski skis to the ski is significantly reduced at low temperatures. This often leads to falling off of ski skis on ski tours in particularly cold conditions and especially after repeated Auffellen the same tour.

Um eine hinreichende Anfangsklebrigkeit zu erzeugen, müssen sehr hohe Klebstoffauflagen von beispielsweise mehr als 250 g/m2 erreicht werden.In order to produce a sufficient initial tack, very high adhesive requirements of, for example, more than 250 g / m 2 must be achieved.

Bei hohen Temperaturen, die durchaus auch 40°C und mehr erreichen können, können beim Abziehen der Skifelle auf der Unterseite der Skis Kleberückstände haften bleiben.At high temperatures, which can reach even 40 ° C and more, can remain sticking on the underside of the skis glue peel off the skins.

Werden Skifelle im feuchten Zustand gelagert, so können sie vergleichsweise schnell von Mikroorganismen befallen und beschädigt werden.If skins are stored in the moist state, they can be attacked by microorganisms and damaged comparatively quickly.

Die Haftung der bekannten Kleber auf der Skifellrückseite ist auf vielen Substraten nicht hinreichend, so dass immer noch Baumwollsubstrate eingesetzt werden, die ebenfalls Nachteile, wie niedrige Weiterreisskraft, hohes Gewicht, hohe Feuchteaufnahme und geringe Dimensionsstabilität unter Feuchteeinfluss und geringe Beständigkeit gegen mikrobiellen Befall besitzen. Zudem können Baumwollsubstrate nicht thermisch randversiegelt werden. Dokument WO2008/122061 beschreibt ein Skifell gemäß dem Oberbegriff von Anspruch 1.The adhesion of the known adhesive on the back of skins is not sufficient on many substrates, so that cotton substrates are still used, which also have disadvantages such as low tear strength, high weight, high moisture absorption and low dimensional stability under the influence of moisture and low resistance to microbial attack. In addition, cotton substrates can not be thermally edge-sealed. document WO2008 / 122061 describes a skimmer according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, ein Skifell der genannten Gattung zu schaffen, das die oben genannten Nachteile vermeidet. Die Aufgabe ist gemäss Anspruch 1 gelöst. Beim erfindungsgemässen Skifell ist die Kleberschicht nicht wie bisher aus einem organischen, sondern aus einem Silikonkleber hergestellt. Versuche haben bei einem solchen Skifell die folgenden Vorteile ergeben.The invention has for its object to provide a skimmer of the type mentioned, which avoids the disadvantages mentioned above. The problem is solved according to claim 1. In the case of the ski skin according to the invention, the adhesive layer is not made of an organic adhesive but of a silicone adhesive, as hitherto. Experiments have shown the following advantages in such a ski.

Beim erfindungsgemässen Skifell konnte eine unveränderte und teilweise sogar höhere Klebrigkeit bei Temperaturen bis -50°C festgestellt werden. Die Kohäsion innerhalb des Klebers blieb auch bei hohen Temperaturen, wie sie beispielsweise bei Sonnenbestrahlung erreicht werden, erhalten. Auch beim Erreichen solcher Temperaturen konnte kein Hängenbleiben von Kleber auf der Skiunterseite festgestellt werden.In the case of the present invention, an unaltered and sometimes even higher tackiness at temperatures down to -50 ° C. could be ascertained. The cohesion within the adhesive remained even at high temperatures, such as those achieved by exposure to sunlight. Even when reaching such temperatures, no sticking of glue on the underside of the ski could be detected.

Der Kleber veränderte seine Eigenschaft auch dann nicht, wenn er mit Wasser in Kontakt gekommen ist, was insbesondere bei Skitouren an wärmeren Tagen der Fall sein kann.The adhesive did not change its properties even if it came in contact with water, which can be the case especially on ski tours on warmer days.

Ein mikrobieller Befall des erfindungsgemässen Skifells ist aufgrund des anorganischen Ursprungs nicht zu erwarten.A microbial infestation of the inventive Skells is not expected due to the inorganic origin.

Es hat sich zudem gezeigt, dass der anorganische Klebei teilvernetzt und die Haftung auch gegenüber anderen Grundmaterialien als Baumwolle optimiert werden kann. Die Vielfalt der möglichen Tragschichten ist damit wesentlich erhöht. Beispielsweise können auch Folien als Tragschichten verwendet werden.It has also been shown that the inorganic adhesive can be partially crosslinked and the adhesion can also be optimized compared to other base materials than cotton. The variety of possible supporting layers is thus substantially increased. For example, films can also be used as base layers.

Der anorganische Kleber ist gemäss einer Weiterbildung der Erfindung ein Silikonkleber. Dieser besitzt die oben genannten Vorteile in besonderem Masse. Solche Silikonkleber sind an sich bereits bekannt und handelsüblich.The inorganic adhesive is according to an embodiment of the invention, a silicone adhesive. This has the above advantages in particular. Such silicone adhesives are already known and commercially available.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Kleber lediglich bereichsweise mit einer wesentlichen Schichtdicke auf die Innenseite der Tragschicht aufgetragen ist. Dadurch wird auch bei vergleichsweise geringer Beschichtungsauflage über die gesamte Fläche von beispielsweise 200 g/m2 eine hinreichende Artfangsklebrigkeit erreicht. Ein weiterer Vorteil des lokalen Auftrags besteht darin, dass zwei Felle, die unbeabsichtigt aneinander kleben, mit vergleichsweise kleinem Kraftaufwand und ohne teilweises Ablösen des Klebers von der Tragschicht wieder voneinander gelöst werden können.According to a development of the invention, it is provided that the adhesive is only partially applied with a substantial layer thickness on the inside of the support layer. As a result, even with a comparatively low coating coverage over the entire area of, for example, 200 g / m 2, a sufficient level of tackiness is achieved. Another advantage of the local job is that two skins that accidentally stick together, with relatively little effort and without partial detachment of the adhesive from the support layer can be solved again from each other.

Nach einer Weiterbildung der Erfindung ist der Kleber streifenförmig auf die Tragschicht aufgetragen. Die Streifen des Klebers erstrecken sich vorzugsweise in Laufrichtung des Skifells. Die Breite der Streifen beträgt vorzugsweise 1 bis 3 mm und vorzugsweise 1,5 bis 2,5 mm. Alternativ ist auch ein punktförmiger oder ein anderer lokaler Auftrag denkbar. Die klebenden Bereiche können beispielsweise auch rechteckig, beispielsweise quadratisch sein.According to a development of the invention, the adhesive is applied in strips on the support layer. The strips of adhesive preferably extend in the direction of the ski skin. The width of the strips is preferably 1 to 3 mm and preferably 1.5 to 2.5 mm. Alternatively, a punctiform or other local order is conceivable. The adhesive areas may for example also be rectangular, for example square.

Vorzugsweise ist der anorganische Kleber mit einer Beschichtungsauflage von wenigstens 200 g/m2 und vorzugsweise wenigstens 250 g/m2 aufgetragen. Die Schichtdicke beträgt dann beispielsweise 0,1 bis 0,4 mm und vorzugsweise 0,3 mm.Preferably, the inorganic adhesive is applied with a coating coverage of at least 200 g / m 2 and preferably at least 250 g / m 2 . The layer thickness is then, for example, 0.1 to 0.4 mm and preferably 0.3 mm.

Beim erfindungsgemässen Verfahren zum Herstellen eines Skifells ist vorgesehen, dass der anorganische Kleber lediglich lokal auf die Innenseite der Tragschicht aufgetragen wird. Der lokale bzw. der bereichsweise Auftrag des Klebers erfolgt vorzugsweise mit einem gezahnten Rakel. Mit einem solchen Rakel kann der Kleber beispielsweise streifenförmig aufgetragen werden. Der streifenförmig aufgetragene Kleber besitzt dann vorzugsweise eine Dicke etwa 0,3 mm. Zwischen diesen Streifen kann ebenfalls eine minimale Schichtdicke bestehen, die aber für die Haftung unwesentlich ist.In the method according to the invention for producing a ski skin, it is provided that the inorganic adhesive is applied only locally to the inside of the base layer. The local or regional application of the adhesive is preferably carried out with a toothed doctor blade. With such a doctor blade, the adhesive can be applied, for example, strip-shaped. The strip-applied adhesive then preferably has a thickness of about 0.3 mm. There may also be a minimum layer thickness between these strips, but this is immaterial for the adhesion.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

Die Figur 1 zeigt einen Ski 1, der eine Oberseite 2 und eine Unterseite 3 aufweist. Auf die Unterseite 3 ist ein Skifell 4 aufgeklebt, das sich im Wesentlichen über die gesamte Unterseite 3 des Skis 1 erstreckt. An dem nicht gezeigten vorderen Ende des Skifells 4 kann ein Beschlag, beispielsweise ein Haken vorgesehen sein, mit dem das Skifell 4 mechanisch lösbar an der Spitze des Skis 1 befestigt ist. Ein entsprechender Beschlag zur Befestigung des hinteren Endes des Skifells 4 am hinteren Ende des Skis 1 kann ebenfalls vorgesehen sein.The FIG. 1 shows a ski 1, which has a top 2 and a bottom 3. On the underside 3 a ski skin 4 is glued, which extends substantially over the entire underside 3 of the ski 1. At the front end of the ski skin 4, not shown, a fitting, for example a hook, may be provided, with which the ski skin 4 is mechanically detachably fastened to the tip of the ski 1. A corresponding fitting for attachment of the rear end of the skinning 4 at the rear end of the ski 1 may also be provided.

Das Skifell 4 ist insbesondere ein so genanntes Steigfell und besitzt eine Tragschicht 6 aus einem Gewebe oder aus einer Folie. Das Gewebe kann aus Baumwolle, Polyester oder einem anderen Textil hergestellt sein. Auf einer Unterseite der Tragschicht 6 ist eine Fellschicht 7 angeordnet, die sich über die gesamte Fläche der Tragschicht 6 erstreckt und die an sich wie üblich aus einer Vielzahl von schräg gestellte Härchen bestehen kann. Auf einer Innenseite 6a der Tragschicht 6 ist eine Klebeschicht 5 aufgetragen, mit welcher das Skifell 4 lösbar mit dem Ski 1 verbunden ist. Das Skifell 4 kann von Hand in an sich bekannter Weise am Ski 1 fixiert und auch wieder nach Gebrauch von Hand abgezogen werden. Dies ist mehrfach möglich.The ski skin 4 is in particular a so-called climbing skin and has a base layer 6 of a fabric or of a film. The fabric may be made of cotton, polyester or other textile. On an underside of the support layer 6, a fur layer 7 is arranged, which extends over the entire surface of the support layer 6 and which may consist of a plurality of obliquely Asked hairs as usual. On an inner side 6 a of the base layer 6, an adhesive layer 5 is applied, with which the ski skin 4 is detachably connected to the ski 1. The ski skin 4 can be fixed by hand in a manner known per se on the ski 1 and can also be pulled off again by hand after use. This is possible several times.

Die Klebeschicht 5 ist aus einem anorganischen Kleber hergestellt. Dieser ist insbesondere und vorzugsweise ein Silikonkleber. Dieser ist vorzugsweise nicht über die gesamte Innenseite 6a der Tragschicht 6 aufgetragen, sondern lediglich lokal. Die Klebeschicht 5 besteht somit lediglich bereichsweise. In den Bereichen, in denen die Klebeschicht 5 aufgetragen ist, beträgt die Dicke des Klebers vorzugsweise mindestens 0,1 mm und vorzugsweise höchstens 0,4 mm. Die optimale Schichtdicke beträgt etwa 0,3 mm. Die Beschichtungsauflage ist vorzugsweise höher als 200 g/m2, vorzugsweise höher als 250 g/m2. Durch den genannten lokalen Auftrag des Klebers und die genannte Schichtdicke wird die erforderliche Anfangsklebrigkeit erreicht. Wesentlich ist hierzu auch die Herstellung der Klebeschicht 5 aus einem anorganischen Kleber und insbesondere einem Silikonkleber. Durch den lokalen Auftrag wird ein höheren Anpressdruck erreicht.The adhesive layer 5 is made of an inorganic adhesive. This is especially and preferably a silicone adhesive. This is preferably not applied over the entire inner side 6a of the support layer 6, but only locally. The adhesive layer 5 is thus only partially. In the areas in which the adhesive layer 5 is applied, the thickness of the adhesive is preferably at least 0.1 mm and preferably at most 0.4 mm. The optimum layer thickness is about 0.3 mm. The coating coating is preferably higher than 200 g / m 2 , preferably higher than 250 g / m 2 . By the said local application of the adhesive and the said layer thickness, the required initial tack is achieved. Essential to this is also the production of the adhesive layer 5 of an inorganic adhesive and in particular a silicone adhesive. Due to the local order, a higher contact pressure is achieved.

Der lokale Auftrag des Klebers kann beispielsweise ein streifenförmiger Auftrag gemäss Figur 2 sein. Die Klebeschicht 5 besteht in diesem Fall aus einer Mehrzahl von Streifen 4a, die parallel und in Längsrichtung des Skifells 4 verlaufen und zwischen denen streifenförmige Bereich 4b bestehen, in denen kein oder sehr wenig Kleber vorhanden ist. Die Breite der Streifen 4a beträgt etwa 1 bis 3 mm und vorzugsweise 1,5 bis 2,5 mm. Die Breite der Bereiche 4b kann gleich oder ähnlich sein.The local application of the adhesive, for example, a strip-like order according FIG. 2 be. The adhesive layer 5 consists in this case of a plurality of strips 4a which extend parallel and in the longitudinal direction of the ski skin 4 and between which strip-shaped area 4b exist in which no or very little adhesive is present. The width of the strips 4a is about 1 to 3 mm and preferably 1.5 to 2.5 mm. The width of the regions 4b may be the same or similar.

Nach einer Variante der Erfindung ist der Kleber punktförmig aufgetragen, wie dies in Figur 3 gezeigt ist. Das Skifell 4' besitzt damit Bereiche 4a', in denen die Dicke der Klebeschicht wie oben erwähnt 0,1 bis 0,4 mm und vorzugsweise 0,3 mm beträgt. Der dazwischen liegende Bereich 4b' besitzt einen kleinen oder keinen Auftrag des Klebers. Anstelle der punktförmigen Bereiche sind auch andere Bereiche, beispielsweise ovale, rechteckige und insbesondere quadratische Bereiche möglich. Denkbar ist auch ein Auftrag, der sowohl streifenförmige als auch punktförmige oder sonst unterschiedliche Bereiche besitzt. Beispielsweise könnten gemäss Figur 3 an den Rändern streifenförmige Bereiche und zwischen diesen punktförmige Bereiche vorhanden sein. Durch den lokalen Auftrag kann die Menge des erforderlichen Klebers minimal gehalten werden.According to a variant of the invention, the adhesive is applied in spots, as in FIG. 3 is shown. The ski skin 4 'thus has areas 4a' in which the thickness of the adhesive layer as mentioned above is 0.1 to 0.4 mm and preferably 0.3 mm. Of the intermediate region 4b 'has little or no application of the adhesive. Instead of punctiform regions, other regions, for example oval, rectangular and in particular square regions, are also possible. It is also conceivable an order that has both strip-shaped and punctiform or otherwise different areas. For example, according to FIG. 3 at the edges strip-shaped areas and be present between these point-shaped areas. The local application can minimize the amount of glue required.

Für den Auftrag des Klebers wird bei einem bevorzugten Verfahren ein gezahnter Rakel verwendet. Mit diesem Rakel wird eine vorbestimmte Menge des Klebers auf die Innenseite 6a der Tragschicht 6 aufgetragen. Der Rakel ist hierbei über einem Tisch fest montiert, während das Skifell zwischen dem Rakel und dem Tisch hindurch gezogen wird. Ein punktförmiger Auftrag ist beispielsweise mit einer Düse möglich. Der Kleber enthält wie üblich ein Lösungsmittel, das nach dem Auftrag verdampft. Anstelle eines lösungsmittelhaltigen anorganischen Klebers ist auch ein anorganischer Kleber denkbar, der ohne Lösungsmittel bei der Applikationstemperatur bereits eine Viskosität besitzt, die eine Verarbeitung zulässt. Die Applikationstemperatur kann auch wesentlich höher sein als die Raumtemperatur. Solche anorganischen Kleber sind ebenfalls an sich bekannt.For the application of the adhesive, a toothed doctor blade is used in a preferred method. With this doctor a predetermined amount of the adhesive is applied to the inside 6 a of the support layer 6. The squeegee is firmly mounted above a table while the skimmer is drawn between the squeegee and the table. A punctiform application is possible, for example, with a nozzle. As usual, the glue contains a solvent which evaporates after application. Instead of a solvent-containing inorganic adhesive, an inorganic adhesive is also conceivable, which already has a viscosity without solvent at the application temperature, which allows processing. The application temperature can also be significantly higher than the room temperature. Such inorganic adhesives are also known per se.
