Abstract

A method for producing cylindrical sleeves (12) for paint rollers (10) is described, in which a covering (30) is fixed with its base (28) on a tubular support (24), after which the base (28) of the covering and the support (24) are perforated. In order to guarantee a mechanically firm connection between the base (28) of the covering and the support (24), even in the immediate vicinity of each perforation hole (32), the perforation holes (32) are produced by an ultrasonic tool. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Walzenhülsen für Farbroller, bei dem ein Bezug mit seinem Boden auf der Außenmantelfläche eines rohrförmigen Trä­ gers befestigt wird, und bei dem anschließend der Bezugs­ boden und der Träger mittels eines Werkzeugs gemeinsam durchlocht werden.The invention relates to a method for producing Roller sleeves for paint rollers, in which a cover with his Soil on the outer surface of a tubular Trä gers is attached, and then the reference floor and the support together using a tool to be perforated.

Insbesondere bei Farbrollern mit einer sog. Innenspeisung, bei welchen das Auftragsmedium beispielsweise durch den mit Walzenhülse verbundenen Handgriff in den zentralen Hohlraum der Walzenhülse eingeleitet und durch die den Träger und den Bezugsboden durchdringenden Löcher ausge­ tragen wird, ergibt sich der Mangel, daß sich der Bezugs­ boden in der unmittelbaren Nachbarschaft der Durchgangs­ löcher vom Träger löst, wenn zur Herstellung der Durch­ gangslöcher bekannte Werkzeuge verwendet werden. Bei die­ sen Werkzeugen handelt es sich üblicherweise um Stanzwerk­ zeuge. Der Bezug besteht bei derartigen Farbrollern bei­ spielsweise aus Lammfell, Plüsch, o. dgl. Der rohrförmige Träger kann aus Hartpapier oder aus Kunststoff sein. Durch die Verwendung an sich bekannter Stanzwerkzeuge wird außer­ dem der Bezugsboden für die gewebten bzw. gewirkten Fasern des Bezugs in der Nachbarschaft jedes Durchgangsloches zerstört. Diese Zerstörung bzw. Unterbrechung des Bezugs­ bodens bringt es mit sich, daß eine Ablösung der geweb­ ten bzw. gewirkten Fasern im Bereich bis zur nächsten mechanisch festen Verbindungs- d. h. Verklebungsstelle ent­ stehen kann. Diese Ablösung von Bestandteilen des Bezugs bringt den Nachteil eines unerwünschten starken Flusses des mit dem Farbroller auf eine Unterlage aufzubringenden Auftragsmediums mit sich.Especially for paint rollers with a so-called internal feed, where the order medium, for example, by the handle connected with roller sleeve in the central Cavity of the roller sleeve initiated and through the Carrier and holes penetrating the reference floor there is a lack that the reference floor in the immediate vicinity of the passage loosens holes from the carrier when making the through well-known tools are used. At the  These tools are usually stamping machines witness. The reference exists for such paint rollers for example made of lambskin, plush or the like. The tubular The carrier can be made of hard paper or plastic. By the use of stamping tools known per se is excluded which is the reference floor for the woven or knitted fibers of the reference in the vicinity of each through hole destroyed. This destruction or interruption of the cover Soil entails detachment of the tissue ten or knitted fibers in the area to the next mechanically firm connection d. H. Ent can stand. This detachment from components of the cover brings the disadvantage of an undesirable strong flow of the paint roller to be applied to a surface Order medium with itself.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Ver­ fahren der eingangs genannten Art zur Herstellung von Wal­ zenhülsen für Farbroller zu schaffen, bei dem während der Herstellung der Durchgangslöcher durch den Bezugsboden und den Träger hindurch eine Ablösung von Bestandteilen des Bezugs verhindert wird, und bei dem außerdem eine Ablö­ sung des Bezugsbodens vom Träger in der Nachbarschaft je­ des Durchgangsloches vermieden wird.The invention is therefore based on the object, a Ver drive of the type mentioned for the manufacture of whale to create zen sleeves for paint rollers, during which Making the through holes through the reference floor and a detachment of components of the Reference is prevented, and also a detachment solution of the reference floor from the carrier in the neighborhood of the through hole is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Bezugsboden und der Träger mittels eines Ultraschall­ werkzeugs durchlocht werden, wobei gleichzeitig der Bezugs­ boden mit dem Träger am Rand jedes Durchgangsloches ver­ schweißt wird.This object is achieved in that the reference floor and the support by means of an ultrasound perforated tool, while the reference floor with the support at the edge of each through hole is welded.

Durch die Anwendung eines Ultraschallwerk­ zeugs an Stelle eines an sich bekannten Stanzwerkzeuges ergibt sich während der Herstellung jedes Durchgangsloches eine Verschweißung des Bezugsbodens mit dem Träger, wo­ durch der Bezugsboden mit dem Träger der Walzenhülse fest verbunden wird. Ein derartige Verschweißung des Bezugs­ bodens mit dem Träger wurde beispielsweise bei Anwendung eines Bezugsbodens in Gestalt eines Trägernetzes (Gaze) festgestellt. Damit wird ein Ablösen von Bestandteilen des Bezugs sicher verhindert. Mit dem erfindungsgemäßen Verfahren sind somit Walzenhülsen für Farbroller herstell­ bar, mit welchen ein flüssiges bis zähflüssiges Auftrags­ medium sehr gleichmäßig auf eine Auftragsfläche aufge­ tragen werden kann.By using an ultrasound machine stuff instead of a stamping tool known per se arises during the manufacture of each through hole a welding of the reference floor to the support, where through the reference floor with the support of the roller sleeve is connected. Such welding of the cover  Soil with the carrier was used, for example a reference floor in the form of a gauze detected. This is a detachment of components of the cover safely prevented. With the invention Processes are thus roller sleeves for paint rollers bar with which a liquid to viscous application medium applied very evenly to an application area can be worn.

Die Erfindung wird anhand der nachfolgenden Be­ schreibung eines in der Zeichnung schematisch dargestell­ ten Farbrollers erläutert. Es zeigtThe invention is based on the following Be Description of a schematically shown in the drawing ten paint rollers explained. It shows

Fig. 1 einen teilweise aufgeschnittenen Farbroller mit einer abschnittsweise dargestellten rohr­ förmigen Achse, und Fig. 1 is a partially cut paint roller with a tubular axis shown in sections, and

Fig. 2 einen vergrößert dargestellten Abschnitt der Walzenhülse des Farbrollers gemäß Fig. 1. FIG. 2 shows an enlarged section of the roller sleeve of the paint roller according to FIG. 1.

Fig. 1 zeigt einen Farbroller 10 mit einer Walzenhülse 12, die durch Scheibenelemente 14 beidseitig dicht verschlossen ist. Das in Fig. 1 auf der linken Seite befindliche Scheibenelement 14 ist mit einer Durchgangsbohrung 16 aus­ gebildet, durch die eine rohrförmige Achse 18 durchgesteckt ist. Die rohrförmige Achse 18 weist entlang des in den zen­ tralen Hohlraum 20 der Walzenhülse 12 angeordneten Abschnit­ tes eine Anzahl Löcher 22 auf. Fig. 1 shows a paint roller 10 with a roller sleeve 12 which is sealed on both sides by disc elements 14 . The disc element 14 located on the left in FIG. 1 is formed with a through bore 16 through which a tubular axis 18 is inserted. The tubular axis 18 has a number of holes 22 along the sections arranged in the central cavity 20 of the roller sleeve 12 .

Die Walzenhülse 12 weist einen rohrförmigen Träger 24 auf, der beispielsweise aus Hartpapier oder aus Kunststoffma­ terial ist. Auf der Außenmantelfläche 26 des rohrförmigen Trägers 24 ist mit seinem Boden 28 ein Bezug 30 befestigt. Die Befestigung des Bezugsbodens 28 auf dem rohrförmigen Träger 24 erfolgt beispielsweise durch eine großflächige Verklebung. The roller sleeve 12 has a tubular support 24 which is made of hard paper or plastic material, for example. On the outer lateral surface 26 of the tubular support 24 , a cover 30 is fastened with its base 28 . The reference base 28 is attached to the tubular support 24 , for example, by a large-area gluing.

Nach der Herstellung der Walzenhülse 12, d. h. nach der Befestigung des Bezugs 30 mit seinem Bezugsboden 28 auf dem rohrförmigen Träger 24 wird die so hergestellte Wal­ zenhülse 12 zur Ausbildung von Durchgangslöchern 32 mit einem Werkzeug durchlöchert. Erfindungsgemäß wird zur Herstellung der Durchgangslöcher 32 ein Ultraschallwerk­ zeug verwendet, mit welchem in einfacher Weise nicht nur die Durchgangslöcher 32 hergestellt werden, sondern gleichzeitig in vorteilhafter Weise der Bezugsboden 28 in unmittelbarer Nachbarschaft jedes Durchgangsloches 32 mit dem rohrförmigen Träger 24 verschweißt wird. Diese Verschweißung des Bezugsbodens 28 mit dem Träger 24 ist in Fig. 2 durch den gewellten Abschnitt 34 an­ gedeutet. Mit der Bezugsziffer 30 ist auch in Fig. 2 der Bezug des Farbrollers bezeichnet. Durch die Schweiß­ verbindung 34 ergibt sich eine mechanisch feste Verbin­ dung des Bezugsbodens 28 auch in der unmittelbaren Nach­ barschaft jedes Durchgangsloches 32 mit dem rohrförmigen Träger 24 der Walzenhülse 12. Da in einem größeren Ab­ stand von jedem Durchgangsloch 32 der Bezugsboden 28 mit dem Träger 24 beispielsweise mittels einer Kleber­ schicht mechanisch fest verbunden ist, ergibt sich mit dem erfindungsgemäßen Verfahren eine Walzenhülse für einen Farbroller, bei der der Bezug 30 an keiner Stelle mit dem rohrförmigen Träger 24 mangelhaft verbunden wäre.After the manufacture of the roller sleeve 12 , ie after the attachment of the cover 30 with its reference base 28 on the tubular support 24 , the roller sleeve 12 thus produced is perforated with a tool to form through holes 32 . According to the invention, an ultrasonic tool is used to produce the through holes 32 , with which not only the through holes 32 are produced in a simple manner, but at the same time the reference base 28 is advantageously welded to the tubular support 24 in the immediate vicinity of each through hole 32 . This welding of the reference floor 28 to the carrier 24 is indicated in Fig. 2 by the corrugated section 34 . The reference number 30 also denotes the reference of the paint roller in FIG. 2. The welded connection 34 results in a mechanically fixed connection of the reference base 28 even in the immediate vicinity of each through hole 32 with the tubular support 24 of the roller sleeve 12 . Since in a larger Ab stood from each through hole 32 of the reference base 28 with the carrier 24, for example by means of an adhesive layer mechanically firmly connected, the method according to the invention results in a roller sleeve for a paint roller, in which the reference 30 at no point with the tubular Carrier 24 would be poorly connected.

Zur Durchführung des erfindungsgemäßen Verfahrens ist es selbstverständlich erforderlich, daß der Träger 24 und der Bezugsboden 28 durch geeignete Auswahl der Ma­ terialien miteinander verschweißbar sind.To carry out the method according to the invention it is of course necessary that the carrier 24 and the reference base 28 are welded together by suitable selection of Ma materials.
