Abstract

An engraved (3) printing roller (2) has a series of raised plateaus (7) that rotate against a matching tool (3). The engraved surface has an anti-stick coating (11) on the non-raised surfaces. The anti-stick surface is Teflon (R) and incorporates chromium, boron or nickel.

Description

Beim sog. „Thermobonding" eines Vlieses werden die Filamente des Vlieses abschnittsweise in einem regelmäßigen Muster miteinander verschweißt. Der Anteil der verschweißten Fläche an der Gesamtfläche beträgt hierbei üblicherweise unter 20 %.At the so-called "thermobonding" of a nonwoven the filaments of the fleece sections in a regular pattern welded together. The proportion of welded area on the total area is usually below 20%.

Es ist bekannt, das Thermobonding des Vlieses mittels einer Vorrichtung zu bewerkstelligen, die einen Walzenspalt umfasst, der von einer beheizten glatten und einer beheizten Gravurwalze gebildet wird. Letztere weist an ihrem Arbeitsumfang eine Gravur auf, deren Plateauflächen zu der glatten Walze in dem Walzenspalt einen Abstand aufweisen, dass die Plateauflächen das Vlies verdichten und an den verdichteten Stellen einen Temperatureintrag bewirken, der zum Verschweißen der Filamente in dem verdichteten Bereich führt.It is known, the thermobonding of the web by means of a device to accomplish that includes a nip of a heated smooth and a heated gravure roll is formed. The latter has an engraving on its scope of work, the plateau areas to the smooth roller in the nip at a distance that the plateau areas compress the fleece and at the compacted places a temperature entry cause the welding the filaments in the densified area leads.

Mit zunehmender Produktionsgeschwindigkeit muss zumindest die Gravurwalze auf immer höhere Temperaturen aufgeheizt werden, da die Zeit, die für den zum Verschweißen benötigten Temperatureintrag zur Verfügung steht, abnimmt. Es hat sich gezeigt, dass ab einer bestimmten Geschwindigkeit das Vlies insbesondere am Produktrand dazu neigt, einzureißen und einen Walzenwickel zu bilden.With increasing production speed must at least the gravure roll to ever higher Temperatures are heated up as the time spent for the weld together required Temperature entry available stands, decreases. It has been shown that at a certain speed the Fleece in particular at the product edge tends to tear down and to form a roll winding.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Gravurwalze derart weiterzubilden, dass mit ihr höhere Produktionsgeschwindigkeiten möglich sind.Of the The invention is therefore based on the object, a gravure roll such to educate that with her higher Production speeds possible are.

Diese Aufgabe wird durch die in Anspruch 1 wiedergegebene Gravurwalze gelöst.These The object is achieved by the recited in claim 1 gravure roll solved.

Dadurch, dass die Gravur zumindest teilweise eine Anti-Haft-Schicht aufweist, wird verhindert, dass Filamente des zwischen den verschweißten Bereichen zum Auffasern neigenden Vlieses an den Gravurflanken haften bleiben und aufschmelzen. Es wird aufgrund der erfindungsgemäßen Weiterbildung der Gravurwalze also verhindert, dass sich in den Vertiefungen der Gravur Schmelze ansammelt, an der Filamente der unverschmolzenen und damit unverfestigten Bereiche des Vlieses anhaften.Thereby, that the engraving has at least partially an anti-adhesion layer, Prevents filaments of between the welded areas to adhere to the fibers tending to fusing adhering to the engraving flanks and melt. It is due to the development of the invention Engraving roller thus prevents the engraving in the recesses Melt accumulates, on the filaments of unfused and thus cling to unconsolidated areas of the web.

Es ist möglich, die gesamte Oberfläche der Gravurwalze mit einer Anti-Haft-Schicht zu versehen. Versuche haben jedoch gezeigt, dass die erzielbaren Bearbeitungsgeschwindigkeiten gegenüber einer Vollbeschichtung nicht reduziert werden, wenn die Plateauflächen keine Anti-Haft-Schicht aufweisen. Dies ist insbesondere deshalb von Bedeutung, da somit der Außenumfang der Gravurwalze mechanisch nachbearbeitet werden kann, ohne dass es einer Erneuerung der Beschichtung bedarf.It is possible, the entire surface the gravure roller with an anti-adhesive layer to provide. Experiments have shown, however, that the achievable processing speeds across from a full coating can not be reduced if the plateau surfaces no Have anti-adhesive layer. This is especially important because thus the outer circumference the gravure roller can be mechanically reworked without it requires a renewal of the coating.

Für Vliese aus thermoplastischem Material mit niedrigem Schmelzpunkt, so dass Thermobonding-Temperaturen von < 250° Celsius ausreichend sind, hat sich eine Teflon-Beschichtung als besonders gut geeignet erwiesen.For nonwovens thermoplastic material with low melting point, so that Thermobonding temperatures of <250 ° Celsius are sufficient, has a Teflon coating as special well proven.

Sind aufgrund anderer Materialien oder höherer Bearbeitungsgeschwindigkeiten auch höhere Temperaturen erforderlich, so kann die Anti-Haft-Schicht beispielsweise Chrom, Bohr und/oder Nickel umfassen.are due to other materials or higher processing speeds also higher temperatures required, the anti-adhesion layer may, for example, chromium, Include drilling and / or nickel.

Die Erfindung soll nun anhand der Zeichnung, die ausschnittsweise und schematisch eine erfindungsgemäße Gravurwalze in Anlage mit einer glatten Walze zeigt, erläutert werden.The Invention will now be based on the drawing, the partial and schematically an engraved roller according to the invention to be explained in Appendix with a smooth roller.

Die Gravurwalze 1 weist einen Arbeitsumfang 2 auf, an dem eine Gravur 3 vorgesehen ist.The gravure roll 1 indicates a scope of work 2 on, on which an engraving 3 is provided.

Die Gravurwalze 1 bildet zusammen mit einer in der Zeichnung darüber angeordneten glatten Walze 4 einen Walzenspalt 5, durch den zwecks Thermobonding eine Bahn 6 aus Vlies kontinuierlich zugeführt wird. Bei dem in der Zeichnung dargestellten Ausführungsbeispiel rotieren die Gravurwalze 1 und die glatte Walze 4 um die Drehachsen F1, F2 in dem durch die Pfeile P1, P2 symbolisierten Drehsinn, so dass die Bahn in der von dem Betrachter fortweisenden Richtung verläuft.The gravure roll 1 forms together with a arranged in the drawing smooth roller 4 a nip 5 , by the purpose of thermobonding a train 6 is fed continuously from non-woven. In the embodiment shown in the drawing, the gravure roll rotate 1 and the smooth roller 4 about the axes of rotation F1, F2 in the direction of rotation symbolized by the arrows P1, P2, so that the path runs in the direction away from the viewer.

Sowohl die Gravurwalze 1 als auch die glatte Walze 4 werden auf herkömmliche Weise, beispielsweise durch im Inneren angeordnete Heizelemente oder auch durch äußere Heizstrahler beheizt.Both the gravure roll 1 as well as the smooth roller 4 are heated in a conventional manner, for example by heating elements arranged inside or also by external radiant heaters.

Wie aus der Zeichnung sinnfällig wird, erfährt die Bahn 6 beim Durchtritt auf den Walzspalt 5 im Bereich der Plateauflächen 7 eine Verdichtung und Aufheizung. Die über den Plateauflächen 7 befindlichen Bereiche 8 der Bahn 6 werden hierbei erwärmt, so dass die Filamente in diesen Bereichen 8 miteinander verschweißen. As is apparent from the drawing, learns the web 6 when passing on the nip 5 in the area of plateau areas 7 a compression and heating. The over the plateau areas 7 located areas 8th the train 6 are heated in this case, so that the filaments in these areas 8th weld together.

Mit Ausnahme der Plateauflächen 7, d.h. an den Gravurflanken 9 und an den Gravurböden 10 ist eine Antihaftbeschichtung 11 aufgebracht. Sie verhindert, dass aufgeschmolzene Filamente in diesen Bereichen haften bleiben und zu einer Anreicherung von Schmelze führen, an der nicht verdichtete Bereiche 12 haften bleiben.With the exception of the plateau areas 7 , ie at the engraving edges 9 and at the gravure floors 10 is a non-stick coating 11 applied. It prevents molten filaments from sticking in these areas and leading to an accumulation of melt at the non-compacted areas 12 stick to it.
