Definitions
- the present invention relates to round disc brushes with braided steel wires.
- Rotary or ring steels are used as cutting tools, depending on whether the process is used for elastomers up to or above about 90 Shore A.
- Polyurethanes, hot-melt adhesives, in particular from the group of polyolefins and polyamides, and thermoplastic block copolymers are particularly suitable for the bond, in particular if they also have a certain elastomeric property.
- the wires can be glued into the braids after they have been produced by immersing them in the liquid components of the plastics and then ensuring that they harden.
- the braids When using polyurethane, for example, the braids are immersed in a freshly prepared solution of diisocyanates and polyols and these components are allowed to harden.
- the braids When using hot-melt adhesives, the braids must be heated above the melting temperature of the respective hot-melt adhesive. Then they can be dipped in melted hot melt adhesive. Excess material drips off or can be spun off by rotating briefly.
- thermoplastic block copolymers with certain elastomeric properties such as those offered by Shell under the name “Kraton R ". These substances can be applied like hot melt glue, but give the braids good elasticity after cooling. When the braided steel wires wear out, the plastics used for bonding are either gradually melted again and thereby removed with the grinding dust, or are worn away together with the ends of the steel wires as wear.
- the new disc round brushes with braided steel wires can in principle also be used for other purposes in which good effectiveness and long service life of the round disc brushes are important.
Abstract
Description
Gegenstand der vorliegenden Erfindung sind Scheibenrundbürsten mit gezopften Stahldrähten.The present invention relates to round disc brushes with braided steel wires.
Derartige Rundbürsten werden zu den verschiedensten Zwecken verwendet. Eine neue Verwendung hat sich ergeben aus der Entwicklung eines Verfahrens zum Entfernen von gebrauchten elastomeren Bezügen von Walzen, wobei diese nicht mehr abgebrannt oder abgedreht werden, sondern dadurch entfernt werden, daß an ein Ende des Bezuges der rotierenden Walze bis dicht an den Walzenkern ein rotierender Messerkopf herangeführt wird, der mehrere an einem Wendeplattenhalter montierte Schneidwerkzeuge aufweist und dieser Messerkopf an der rotierenden Walze entlanggeführt wird bis zum anderen Ende des Bezuges.Such round brushes are used for a wide variety of purposes. A new use has arisen from the development of a method for removing used elastomeric covers from rolls, which are no longer burned off or twisted off, but are instead removed by rotating a cover at one end of the cover of the rotating roll close to the roll core Knife head is brought up, which has several cutting tools mounted on an indexable insert holder and this knife head is guided along the rotating roller to the other end of the cover.
Als Schneidwerkzeuge werden dabei Drehstähle oder Ringstähle verwendet, nämlich je nachdem ob das Verfahren angewendet wird für Elastomere bis oder über ca. 90 Shore A.Rotary or ring steels are used as cutting tools, depending on whether the process is used for elastomers up to or above about 90 Shore A.
Bei diesem Verfahren, welches Gegenstand der DE 196 18 613.7 sowie entsprechender Auslandsanmeldungen ist, werden die auch dem Walzenkern verbliebenen Reste der elastomeren Bezüge mit einer oder mehreren nebeneinanderliegenden rotierenden Scheibenrundbürsten mit gezopften Stahldrähten entfernt. Vorzugsweise werden diese Scheibenrundbürsten nach hinten versetzt aber gleichzeitig mit dem rotierenden Messerkopf an der rotierenden Walze entlanggeführt werden.In this process, which is the subject of DE 196 18 613.7 and corresponding international applications, the remnants of the elastomeric coverings which have also remained in the roller core are removed with one or more rotating disc round brushes with braided steel wires lying next to one another. These round disk brushes are preferably offset to the rear, but are simultaneously guided along the rotating roller with the rotating cutter head.
Es hat sich gezeigt, daß die Lebensdauer und die Wirksamkeit handelsüblicher rotierender Scheibenrundbürsten nicht optimal ist. Es wurde jetzt gefunden, daß Wirksamkeit und Lebensdauer der rotierenden Scheibenrundbürsten mit gezopften Stahldrähten dadurch wesentlich verbessert werden könnten, daß die Drähte in den Zöpfen zumindest in dem Außenbereich mit einem elastischen Kunststoff miteinander verklebt sind.It has been shown that the service life and the effectiveness of commercially available rotary disc brushes are not optimal. It has now been found to be effective and long lasting of the rotating disc brushes with braided steel wires could be significantly improved in that the wires in the braids are glued together with an elastic plastic at least in the outer region.
Für die Verklebung kommen vorzugsweise in Frage Polyurethane, Heißschmelzkleber, insbesondere aus der Gruppe der Polyolefine und Polyamide sowie thermoplastische Blockcopolymere, insbesondere wenn diese auch noch eine gewisse elastomere Eigenschaft aufweisen.Polyurethanes, hot-melt adhesives, in particular from the group of polyolefins and polyamides, and thermoplastic block copolymers are particularly suitable for the bond, in particular if they also have a certain elastomeric property.
Die Verklebung der Drähte in den Zöpfen kann nach ihrer Herstellung erfolgen, in dem man diese in die flüssigen Komponenten der Kunststoffe eintaucht und danach dafür sorgt, daß diese aushärten. Bei Verwendung von Polyurethan taucht man beispielsweise die Zöpfe in eine frisch angesetzte Lösung von Diisocyanaten und Polyolen und läßt diese Komponenten aushärten. Bei Verwendung von Heißschmelzklebern müssen die Zöpfe über die Schmelztemperatur des jeweiligen Heißschmelzklebers erhitzt werden. Dann können sie in aufgeschmolzene Heißschmelzkleber eingetaucht werden. Überschüssiges Material tropft ab oder kann durch kurzes Rotieren abgeschleudert werden.The wires can be glued into the braids after they have been produced by immersing them in the liquid components of the plastics and then ensuring that they harden. When using polyurethane, for example, the braids are immersed in a freshly prepared solution of diisocyanates and polyols and these components are allowed to harden. When using hot-melt adhesives, the braids must be heated above the melting temperature of the respective hot-melt adhesive. Then they can be dipped in melted hot melt adhesive. Excess material drips off or can be spun off by rotating briefly.
Gut geeignet sind auch thermoplastische Blockcopolymere mit gewissen elastomeren Eigenschaften, wie sie beispielsweise von der Firma Shell unter der Bezeichnung "KratonR" angeboten werden. Diese Substanzen können wie Heißschmelzkleber aufgetragen werden, verleihen jedoch nach dem Abkühlen den Zöpfen eine gute Elastizität. Die zum Verkleben verwendeten Kunststoffe werden beim Verschleiß der gezopften Stahldrähte nach und nach entweder wieder aufgeschmolzen und dadurch mit dem Schleifstaub entfernt oder aber zusammen mit den Enden der Stahldrähte als Verschleiß abgetragen.Also suitable are thermoplastic block copolymers with certain elastomeric properties, such as those offered by Shell under the name "Kraton R ". These substances can be applied like hot melt glue, but give the braids good elasticity after cooling. When the braided steel wires wear out, the plastics used for bonding are either gradually melted again and thereby removed with the grinding dust, or are worn away together with the ends of the steel wires as wear.
Die neuen Scheibenrundbürsten mit gezopften Stahldrähten sind prinzipiell auch bei anderen Verwendungszwecken einsetzbar, bei denen es auf gute Wirksamkeit und lange Lebensdauer der Scheibenrundbürsten ankommt.The new disc round brushes with braided steel wires can in principle also be used for other purposes in which good effectiveness and long service life of the round disc brushes are important.
Das Verfahren zum Entfernen von gebrauchten elastomeren Bezügen von Walzen ist Gegenstand der oben bereits erwähnten deutschen Patentanmeldung 196 18 613.7.The process for removing used elastomeric covers from rollers is the subject of the above-mentioned German patent application 196 18 613.7.
