Abstract

Die Erfindung betrifft ein aus endlosen Fasern oder Stapelfasern, insbesondere Stahlfasern bestehendes band- oder mattenförmiges Faservlies, z.B. in Form von Stahlwolle, mit einem platten- oder bandförmigem Träger, wobei das Faservlies dadurch auf einfache Weise mit dem Träger verbunden werden kann, daß Teile (15) des Faservlieses (14) durch Ausstanzungen (13) des Trägers (11) gedrückt und von der Gegenseite des Trägers (11) her plattgedrückt sind.The invention relates to a ribbon or mat-shaped non-woven fabric consisting of endless fibers or staple fibers, in particular steel fibers, e.g. in the form of steel wool, with a plate or ribbon-shaped carrier, the nonwoven fabric being able to be connected to the carrier in a simple manner in that parts (15) of the nonwoven fabric (14) are pressed through punched-out portions (13) of the carrier (11) and by the opposite side of the carrier (11) are flattened forth.

Description

Die Erfindung betrifft ein Faservlies entsprechend dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zu seiner Herstellung.The invention relates to a nonwoven fabric according to the preamble of claim 1 and a method for its production.

Ein derartiges Faservlies ist z.B. als Stahlwolle bekannt. Der Einsatz üblicher Stahlwolle, d.h. von Stahlwolle, die aus vorzugsweise in einer Richtung verlaufenden Stahlfasern besteht, ist begrenzt. Der Einsatz bei Hand- und Schwingschleifern sowie Schleifmaschinen mit Schleifscheiben ist nicht möglich, da sich im Betrieb eine Relativbewegung zwischen dem die Stahlwolle tragenden Teil und der Stahlwolle selbst ergeben würde. Man kann die Stahlwolle auch auf einen Träger kleben und am Schleifer festspannen. Beim Kleben ergibt sich jedoch eine geringe Haftung, da die Haftfläche der Stahlwolle gering ist. Außerdem ist die Stahlwolle auch nach dem Kleben noch biegsam, so daß sich der Klebstoff leicht löst. Die Verwendung von Klebstoff hat bei Schleifmaschinen mit rotierenden Schleifscheiben außerdem den Nachteil, daß sich dieser bei hohen Temperaturem zersetzt. Allgemein hat die Verwendung von Klebstoff den Nachteil, daß dieser bei niedrigen Temperaturen an die Oberfläche dringt, da die gesamte Stahlwolle mit Klebstoff getränkt werden muß, um eine Verbindung zwischen der Stahlwolloberfläche und dem Schleifer zu erreichen. Es ist auch bekannt, die Stahlwolle mittels Klammern oder dergl. an einem Träger zu befestigen. Dies ist jedoch für Schleifzwecke ungünstig, da die Klammern zur Oberfläche der Stahlwolle durchdrinqen..Such a nonwoven is e.g. known as steel wool. The use of conventional steel wool, i.e. of steel wool, which preferably consists of steel fibers running in one direction, is limited. Use with hand and orbital sanders as well as sanding machines with sanding discs is not possible, since during operation there would be a relative movement between the part carrying the steel wool and the steel wool itself. The steel wool can also be glued to a support and clamped to the grinder. However, there is little adhesion when gluing, since the adhesive surface of the steel wool is small. In addition, the steel wool is flexible even after gluing, so that the glue is easily released. The use of adhesive in grinding machines with rotating grinding wheels also has the disadvantage that it decomposes at high Temperaturem. In general, the use of adhesive has the disadvantage that it penetrates to the surface at low temperatures, since the entire steel wool must be soaked with adhesive in order to achieve a connection between the steel wool surface and the grinder. It is also known to fasten the steel wool to a support by means of clips or the like. However, this is unfavorable for grinding purposes, since the staples penetrate to the surface of the steel wool.

Der Erfindung liegt die Aufgabe zugrunde, ein Faservlies, insbes. Stahlwolle mit einem Träger auf einfache Weise zu verbinden.The invention has for its object to connect a nonwoven fabric, in particular steel wool with a carrier in a simple manner.

Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Anspruch 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung sowie ein Herstellungsverfahren ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by the features specified in claim 1. Expedient embodiments of the invention and a manufacturing method result from the subclaims.

Bei einem Faservlies in Form von Stahlwolle besteht der Träger z.B. aus Pappe und hat kreuzförmige Ausstanzungen. Die Oberseite des Trägers ist mit der Stahlwolle belegt, die von der Trägeroberseite her durch die Ausstanzungen gedrückt ist, und zwar derart, daß sich auf der Trägerunterseite noppenförmige Erhebungen bilden und die die Ausstanzungen begrenzenden Lappen aufgebogen werden. Die noppenförmigen Erhebungen bestehen aus Schlaufen der Stahlwolle. Dabei ist es entscheidend, daß die Fasern der Stahlwolle nicht beschädigt werden. Werden zuerst die die Ausstanzungen begrenzenden Lappen niedergedrückt, dann greifen sie in die die Erhebungen bildenden Stahlwolleschlaufen. Werden nun auch die Schlaufen niedergedrückt, dann wird der Halt der Stahlwolle am Träger dadurch gewährleistet, daß die Lappen der Ausstanzungen in die Schlaufen greifen und ein Durchziehen der Schlaufen zur Trägerunterseite verhindern. Das Niederdrücken der Schlaufen ist einem Vernieten ,ähnlich, d.h., daß die Schlaufen nicht umgelegt, sondern durch einen vertikalen Druck plattgedrückt werden.In the case of a non-woven fabric in the form of steel wool, the carrier consists, for example, of cardboard and has cross-shaped punchings. The top of the carrier is covered with the steel wool, which is pressed from the top of the carrier through the punched out, in such a way that nub-shaped elevations form on the underside of the beam and the flaps delimiting the punched out are bent. The knob-shaped elevations consist of loops of steel wool. It is important that the steel wool fibers are not damaged. First the punched-out limiting the cloth depressed, then they engage in the projections forming S tahlwolleschlaufen. If the loops are now also pressed down, the hold of the steel wool on the carrier is ensured in that the lugs of the punched holes reach into the loops and prevent the loops from being pulled through to the underside of the carrier. Depressing the loops is similar to riveting, ie the loops are not flipped over, but are flattened by vertical pressure.

Durch diese Art der Verbindung von Stahlwolle und Träger ergibt sich ein sicherer Halt der Stahlwolle am Träger. Eine Relativbewegung zwischen dem Träger und der Stahlwolle, insbes. der Stahlwolleoberfläche ist nicht mehr möglich, da beim Durchstoßen der Stahlwolle durch den Träger auch an der Stahlwolleoberfläche liegende Fasern durch die Prägeausstanzungen gedrückt und mit deren Lappen verbunden werden.This type of connection of steel wool and carrier results in a secure hold of the steel wool on the carrier. A relative movement between the carrier and the steel wool, in particular the steel wool surface, is no longer possible, since when the steel wool is pierced by the carrier, fibers lying on the steel wool surface are also pressed through the embossed punchings and connected to their flaps.

Der Einsatzbereich derartiger Stahlwolle ist zunächst gleich dem üblicher Stahlwolle, jedoch kann die Stahlwolle vor allem bei Hand- oder Schwingschleifern verwendet werden. Gegenüber der Verwendung von Schleifpapier in Hand- oder Maschinenschleifern ergibt sich der Vorteil, daß sich Stahlwolle mechanisch wieder säubern läßt, während sich das Schleifpapier zusetzt, und daß sich keine z.B. kreisförmigen Schleifspuren wie bei Verwendung von Schleifpapier infolge der Schleifpartikel ergeben.The area of application of such steel wool is initially the same as the usual steel wool, but the steel wool can be used above all in hand or orbital sanders. Compared to the use of sandpaper in hand or machine sanders, there is the advantage that steel wool can be mechanically cleaned again while the sandpaper is clogged and that e.g. circular grinding marks as when using abrasive paper due to the abrasive particles.

Im übrigen ist das Einsatzgebiet derartiger Stahlwolle sehr umfangreich:

  • Bei Walzen von Bügelmangeln ist es bekannt, bandförmige Stahlwolle zu verwenden, die spiralförmig auf die Walzen gewickelt wird. Dabei ergibt sich der Nachteil, daß sich die Dicke der Stahlwolle durch die Bewegung der Fasern in Längsrichtung, d.h. zu den Enden hin, verringert, und dadurch kein ausreichender Anpreßdruck mehr erzielt wird. Dieser Nachteil kann bei der neuen Stahlwolle nicht auftreten, da keine Wanderbewegung möglich ist.
The area of use of such steel wool is also very extensive:
  • In the case of rolls of ironing ironers, it is known to use band-shaped steel wool which is wound spirally on the rolls. This has the disadvantage that the thickness of the steel wool is reduced by the movement of the fibers in the longitudinal direction, ie towards the ends, and as a result a sufficient contact pressure is no longer achieved. This disadvantage cannot occur with the new steel wool, since no moving movement is possible.

Die Stahlwolle kann jedoch auch z.B. in Form von Platten als Dämmplatten, zur elektrischen Isolierung (Faraday-Käfig), zur Herstellung von Stoffen für Schutzanzüge usw. verwendet werden.However, the steel wool can also e.g. in the form of panels as insulation panels, for electrical insulation (Faraday cage), for the production of fabrics for protective suits, etc.

Auch ist die vorgeschlagene.Art der Befestigung eines Faservlieses an einem Träger nicht auf Stahlfasern beschränkt, sondern ist z.B. auch bei Glasfasern möglich.Also, the proposed type of fastening a nonwoven fabric to a carrier is not limited to steel fibers, but is e.g. also possible with glass fibers.

Die Erfindung wird nachstehend anhand der Fig. 1 bis 6 beispielsweise erläutert. Es zeigt:

  • Fig. 1 eine Aufsicht des kreuzförmige Ausstanzungen aufweisenden Trägers,
  • Fig. 2 eine Seitenansicht des Trägers nach dem Durchdrücken der Stahlwolleschlaufen,
  • Fig. 3 eine Fig. 2 entsprechende Ansicht des Trägers von unten,
  • Fig. 4 einen Schnitt des Trägers im Bereich der durchgedrückten Stahlwolleschlaufen,
  • Fig. 5 eine Seitenansicht des Trägers nach dem Niederdrücken der Lappen, und
  • Fig. 6 eine Seitenansicht des Trägers nach dem Niederdrücken der Schlaufen.
The invention is explained below with reference to FIGS. 1 to 6, for example. It shows:
  • 1 is a plan view of the cross-shaped punched carrier,
  • 2 is a side view of the carrier after pressing the steel wool loops,
  • 3 a view corresponding to FIG. 2 of the carrier from below,
  • 4 shows a section of the carrier in the area of the pressed-through steel wool loops,
  • Fig. 5 is a side view of the carrier after pressing the tabs, and
  • Fig. 6 is a side view of the carrier after depressing the loops.

Fig. 1 zeigt die Aufsicht eines rechteckigen Trägers 11 z.B. aus Pappe, der mehrere Reihen kreuzförmiger Ausstanzungen 13 aufweist. An den Seitenrändern hat der Träger 11 je zwei Kerbrillen 12, so daß er durch Umbiegen der seitlichen Randteile an einem Hand- oder Schwingschleifer festgespannt werden kann.Fig. 1 shows the top view of a rectangular beam 11 e.g. made of cardboard, which has several rows of cross-shaped punchings 13. At the side edges, the carrier 11 has two notches 12, so that it can be clamped to a hand or orbital sander by bending the lateral edge parts.

Fig. 2 zeigt den auf der Oberseite mit Stahlwolle 14 belegten Träger. An den Ausstanzungen 13 sind Teile der Stahlwolle 14 von deren Oberfläche her durch die Ausstanzungen 13 gedrückt, so daß auf der obenliegenden Unterseite des Trägers 11 Schlaufen 15 in Form noppenförmiger Erhebungen gebildet sind. Wichtig ist dabei, daß die Fasern der Stahlwolle beim Durchdrücken durch den Träger 11 nicht beschädigt werden, so sonst kein einwandfreier Halt erreicht wird und bei der Benutzung die Fasern durch den Träger zurückgezogen werden könnten. Die durch die Ausstanzungen gebildeten Lappen 16 werden, wie Fig. 2 zeigt, beim Durchstoßen der Stahlwolle aufgebogen.Fig. 2 shows the carrier covered with steel wool 14 on the top. At the cutouts 13, parts of the steel wool 14 are pressed from the surface thereof through the cutouts 13, so that loops 15 in the form of knob-shaped elevations are formed on the upper underside of the carrier 11. It is important that the fibers of the steel wool are not damaged when pressed through the carrier 11, otherwise a perfect hold is not achieved and the fibers are withdrawn by the carrier during use could become. The flaps 16 formed by the punched-out portions, as shown in FIG. 2, are bent open when the steel wool is pierced.

Fig. 3 zeigt eine Aufsicht der Unterseite des Trägers 11 nach dem Durchdrücken der Stahlwolle.3 shows a top view of the underside of the carrier 11 after the steel wool has been pressed through.

Fig. 4 zeigt einen Schnitt durch eine Reihe Schlaufen in Fig. 3. Aus dieser Darstellung geht hervor, daß vor allem auch Oberflächenteile der Stahlwolle durch die Aussparungen 13 gedrückt sind. Gerade diese Oberflächenteile der Stahlwolle sind es, die dafür sorgen, daß bei der Bearbeitung mittels solch einer Stahlwolle keine Relativbewegung zwischen der Stahlwolle und dem Träger auftritt.FIG. 4 shows a section through a series of loops in FIG. 3. This representation shows that above all surface parts of the steel wool are pressed through the cutouts 13. It is precisely these surface parts of the steel wool that ensure that there is no relative movement between the steel wool and the carrier during processing by means of such steel wool.

Fig. 5 zeigt eine Seitenansicht des Trägers nach dem Niederdrücken der Lappen 16. Beim Zurückdrücken dieser Lappen 16 werden auch die Schlaufen 15 etwa zylindrisch geformt.5 shows a side view of the carrier after the tabs 16 have been pressed down. When these tabs 16 are pressed back, the loops 15 are also shaped approximately cylindrically.

Fig. 6 zeigt die plattgedrückten bzw. vernieteten Schlaufen 18. Die Schlaufen überdecken nun die wieder in die Trägerebene gebogenen Lappen 17, die zwischen die einzelnen Fasern der Schlaufen greifen und dadurch den Halt der Stahlwolle am Träger bewirken.6 shows the flattened or riveted loops 18. The loops now cover the tabs 17 which are bent back into the carrier plane and which engage between the individual fibers of the loops and thereby cause the steel wool to hold on to the carrier.

In bestimmten Fällen kann es zweckmäßig sein, nicht nur eine Lage Stahlwolle, sondern zwei oder mehrere Lagen zu verwenden, deren Fasern jeweils vorzugsweise in einer Richtung verlaufen und deren Richtungen sich vorzugsweise rechtwinklig kreuzen.In certain cases, it may be appropriate to use not just one layer of steel wool, but two or more layers, the fibers of which preferably each run in one direction and the directions of which preferably cross at right angles.
