In konventionellen Behandlungsanlagen dieser Art werden Lackdrähte auf Basis lösemittelhaltiger Beschichtungsstoffe im Mehrschichtaufbau mit verschiedenen Lackschichten versehen, beispielsweise einer Grundierung zur Erhöhung der Alterungsbeständigkeit und besseren Haftung der Folgebeschichtung, einer Hauptschicht zur Isolierung und einer äußeren Schicht als Bondcoat bzw. Backlack. Die Vorteile der Wärmetrocknung liegen in der hohen Temperaturbeständigkeit des Isolierlacks, der Beschichtungsgüte und insbesondere Porenfreiheit und in der kostengünstigen Fertigung. Problematisch ist allerdings die Entsorgung des ab dampfenden Lösemittels und dessen Beeinträchtigung der Arbeitsumgebung.In Conventional treatment plants of this type become enameled wires Base solvent-based Coating materials in multi-layer construction with different paint layers provided, for example, a primer to increase the aging resistance and better adhesion of the subsequent coating, a main layer to the Insulation and an outer layer as a bondcoat or baked enamel. The advantages of heat drying are in the high temperature resistance the insulating varnish, the coating quality and in particular freedom from pores and in the cost-effective Production. However, the problem is the disposal of the steaming from solvent and its impairment the working environment.
Aus diesem Grunde wurde bereits die UV-Strahlungsvernetzung von lösemittelfreien Lacksystemen, bei denen die aufgetragene Beschichtungsmenge auch der vernetzten Masse entspricht, vorgeschlagen. Die UV-Bestrahlung konnte jedoch in Konkurrenz zur herkömmlichen Wärmetrocknung bislang nicht zum industriellen Einsatz gebracht werden.Out For this reason, the UV radiation crosslinking of solvent-free Paint systems in which the applied coating amount also the crosslinked mass corresponds, proposed. The UV irradiation could but in competition with the conventional ones Heat drying so far not be put to industrial use.

Dementsprechend wird erfindungsgemäß eine der Wärmehärtungsstation entlang der Transportstrecke vor- und/oder nachgeordnete, mit mindestens einer UV-Strahlungsquelle bestückte UV- Härtungsstation zur UV-Strahlungshärtung einer auf das Fadenmaterial aufgebrachten lösemittelfreien Lackschicht vorgeschlagen. Dadurch lassen sich in einem kontinuierlichen Produktionsprozess mit einfach beizustellenden UV-Einrichtungen wahlweise zusätzliche Beschichtungen schaffen, welche optimal auf die erforderlichen Eigenschaften abgestimmt sind. Insbesondere lassen sich bestehende Anlagen kostengünstig mit geringem Platzbedarf nachrüsten bzw. ergänzen, so dass verschiedenartige Lackschichten aufgebracht werden können, wobei mindestens eine wärmetrocknende Schicht mit einer UV-vernetzten Schicht kombiniert wird.The Invention is based on the idea of classic heat drying to combine with the UV light-induced cross-linking to thereby special property profiles of the paint coating of filamentous material to achieve. Accordingly, according to the invention, one of the heat curing station along the transport path forward and / or downstream, with at least a UV radiation source equipped UV curing station for UV radiation a solvent-free lacquer layer applied to the thread material proposed. This can be done in a continuous production process optionally with additional UV devices optionally additional Create coatings that optimally to the required properties are coordinated.

Um eine gleichmäßige Härtung im Durchlauf zu erreichen, ist es von Vorteil, wenn mehrere UV-Strahlungsquellen konzentrisch um das hindurchlaufende Fadenmaterial herum vorzugsweise in gleichem Winkelabstand voneinander verteilt angeordnet sind. Eine weitere Verbesserung wird dadurch erreicht, dass mehrere UV-Strahlungsquellen entlang der Transportstrecke im Abstand voneinander angeordnet sind. Besonders günstig ist es, wenn drei im Abstand voneinander längs der Transportstrecke angeordnete UV-Strahlungsquellen um das hindurchlaufende Fadenmaterial herum im Winkelabstand von 120° zueinander verteilt sind. Dabei sollten die vorzugsweise als Quecksilberdampflampen stabförmig ausgebildeten UV-Strahlungsquellen parallel zu dem Fadenmaterial ausgerichtet sein.Around a uniform hardening in the To achieve throughput, it is beneficial if multiple UV radiation sources concentric around the passing yarn material around preferably are arranged distributed at the same angular distance from each other. A further improvement is achieved by having multiple UV radiation sources along the transport path are arranged at a distance from each other. Very cheap it is when three spaced apart along the transport path UV radiation sources around the passing thread material around at an angular distance of 120 ° to each other are distributed. In doing so, they should preferably be used as mercury vapor lamps rod-shaped formed UV radiation sources parallel to the thread material be aligned.

Eine weitere Verbesserung sieht vor, dass der Durchlaufkanal entlang mehrerer in Durchlaufrichtung hintereinander angeordneter UV-Strahlungsquellen durchgängig verläuft.to Influencing the process and discharging fission products it is advantageous if the thread material in a permeable to UV radiation passage channel, especially quartz tube out is. Another improvement provides that the flow channel along several in the direction of passage successively arranged UV radiation sources throughout runs.
Für Servicearbeiten während des Betriebs ist es vorteilhaft, wenn der Durchlaufkanal aus zwei voneinander trennbaren Rohrhalbschalen besteht. Die Instandhaltung wird auch dadurch erleichtert, dass der Durchlaufkanal durch mehrere jeweils einer UV-Strahlungsquelle zugeordnete, über Zwischenstücke durchgängig miteinander verbundene Einzelrohre gebildet ist.For service work while of the operation, it is advantageous if the flow channel of two consists of separable pipe shells. The maintenance is also facilitated by the passage channel through several each associated with a source of UV radiation, intermeshing with each other throughout connected individual tubes is formed.
Eine weitere vorteilhafte Ausgestaltung sieht vor, dass der Durchlaufkanal an seinem einlaufseitigen Endabschnitt für das Fadenmaterial einen Einlass zur Zufuhr von Prozessgas (insbesondere auch Luft) und an seinem auslaufseitigen Endabschnitt einen Auslass zur Ableitung des in Durchlaufrichtung des Fadenmaterials strömenden Prozessgases aufweist.A Further advantageous embodiment provides that the flow channel at its inlet end portion for the thread material an inlet for the supply of process gas (especially air) and at his outlet side end portion an outlet for discharging the in Having flow direction of the yarn material flowing process gas.
