Description

Die Erfindung betrifft eine Anlage zum kontinuierlichen Herstellen und Oberflächenveredeln einer Plattenbahn aus einem Vlies, das mindestens mit einem Bindemittel versetzte lignozellulose- und/oder zellulosehaltige Späne, Fasern oder dergleichen Teilchen enthält, mit einer kontinuierlich arbeitenden und einen Preßspalt aufweisenden, beheizten Preßvorrichtung, insbesondere einer Doppelband-Fertigpresse, Kalanderpresse und dergleichen.The invention relates to a plant for the continuous production and surface finishing of a sheet of web made of a nonwoven fabric containing chips, fibers or similar particles containing lignocellulose and / or cellulose mixed with at least one binder, with a continuously operating and having a press nip, heated press device, in particular one Double belt finishing press, calender press and the like.

Aus der DE-AS 25 23 670 ist ein Verfahren zum kontinuierlichen Herstellen und gleichzeitigen Beschichten von Spanplatten, die mit mindestens einer Decklage aus mit Kunstharz getränktem Papier belegt sind, bekannt. Bei diesem bekannten Verfahren, das auch als Eingangsverfahren bezeichnet wird, müssen spezielle Papiere mit einer erhöhten Wasserdampfdurchlässigkeit verwendet werden, um die Bildung von Wasserdampfblasen zu vermeiden. Die Qualität der erzielbaren Spanplattenoberfläche ist dabei wesentlich durch das verwendete Beschichtungspapier vorgegeben.From DE-AS 25 23 670 a method for the continuous production and simultaneous coating of chipboard, which are covered with at least one top layer made of paper impregnated with synthetic resin, is known. In this known method, which is also referred to as the input method, special papers with an increased water vapor permeability have to be used in order to avoid the formation of water vapor bubbles. The quality of the chipboard surface that can be achieved is largely determined by the coating paper used.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage der eingangs genannten Art zu schaffen, die eine über das Übliche hinausgehende Vielfalt an Möglichkeiten der Gestaltung hochwertiger Plattenoberflächen gestattet und gleichzeitig besonders wirtschaftlich ist.The invention has for its object to provide a system of the type mentioned, which allows a variety of options for designing high-quality plate surfaces that goes beyond the usual and at the same time is particularly economical.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, das wenigstens einem der den Preßspalt bildenden, im Betrieb temperierten Organe eine Auftragsvorrichtung für Lack oder Farbe zugeordnet und/oder zumindest eine Präge- und/oder Profilierungseinrichtung für die mit oder ohne Farbstoff vorbehandelte Deckschichtteilchen aufweisende Plattenbahn vorgesehen ist.According to the invention this object is achieved in that at least one of the organs forming the press nip and tempered during operation is assigned an application device for lacquer or paint and / or at least one embossing and / or profiling device is provided for the plate web which has been pretreated with or without dye.

Die mit einer derartigen Anlage gefertige Plattenbahn besitzt einen sehr hohen Veredelungsgrad, wobei von ganz wesentlicher Bedeutung ist, daß dieser sehr hohe Veredelungsgrad mit vergleichsweise geringem Aufwand in einem Eingangverfahren erzielbar ist.The plate web manufactured with such a system has a very high degree of refinement, it being very important that this very high degree of refinement can be achieved with comparatively little effort in an entry procedure.

Außerordentlich kostengünstig ist auch, daß der bevorzugt von einer Doppelband-Fertigpresse gebildete Preßspalt gleichzeitig als Trocknungs- und/oder Aushärtungsstrecke dient. Damit entfallen ein Wärmeofen, eine Elektronenstrahlhärtung, eine IST-Trocknung oder wenigstens eine heiße, verchromte Walze zum Zwecke des Aushärtens des aufgetragenen Lackes.It is also extremely inexpensive that the press nip, which is preferably formed by a double-belt finishing press, also serves as a drying and / or curing section. This eliminates the need for a heating oven, electron beam curing, actual drying or at least a hot, chrome-plated roller for the purpose of curing the applied paint.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Expedient refinements and developments of the invention are specified in the subclaims.

Ein Ausführungsbeispiel einer Anlage zur Durchführung des Verfahrens nach der Erfindung wird unter Bezugnahme auf die Zeichnung nachfolgend näher erläutert.An embodiment of a system for performing the method according to the invention is explained in more detail below with reference to the drawing.

Eine Anlage zur kontinuierlichen Herstellung und Oberflächenveredelung einer Plattenbahn 1 aus mit mindestens einem Bindemittel versetzten lignozellulose- und/oder zellulosehaltigen Spänen, Fasern oder dergleichen Teilchen umfaßt einen um Umlenkrollen bzw. Umlenkwalzen 2 und um eine verstellbare Spannwalze 3 geführten Endlos-Träger 4 für das jeweilige Vlies 5, welches in Richtung des Pfeiles 6 über ein vorzugsweise vorgesehenes Leitflächenorgan 7 zum Spalt 8 einer mit 9 bezeichneten Doppelband-Fertigpresse bewegt wird.A system for the continuous production and surface finishing of a plate web 1 from lignocellulosic and / or cellulosic chips, fibers or similar particles mixed with at least one binder comprises a continuous carrier 4 for the respective one, guided around deflecting rollers or deflecting rollers 2 and around an adjustable tensioning roller 3 Fleece 5, which is moved in the direction of arrow 6 via a preferably provided guide surface element 7 to the gap 8 of a double-belt finishing press designated by 9.

Beispielsweise ist eine derartige, kontinuierlich arbeitende und beheizte Doppelband-Fertigpresse in der europäischen Patentanmeldung 81 109 682.5 beschrieben.For example, such a continuously working and heated double-belt finishing press is described in European patent application 81 109 682.5.

Demgemäß sind ein oberes endlos umlaufendes Band 10 sowie ein unteres endlos umlaufendes Band 11 vorgesehen, zwischen denen das Vlies 5 gemäß Richtunsgpfeil 6 transportiert und während des Durchlaufvorganges des Vorgängen des Vor- und Hauptpressens sowie des Kalibrierens unterzogen wird.Accordingly, an upper endless belt 10 and a lower endless belt 11 are provided between to which the fleece 5 is transported according to the direction arrow 6 and is subjected to the pre-pressing and main pressing as well as the calibration processes during the through process.

Auf der dem Vlies 5 abgewandten Rückseite 12 der Bänder 10, 11 liegt im gesamten Preßbereich 13, der aus einem Vorpreßbereich 14 und einem Hauptpreß- sowie Kalibrierbereich 15 besteht, ein Gleitbelag 16 an, der beispielsweise ein auf ein Widerlager 17 im Preßbereich 13 aufvulkanisierter Gummi sein kann.On the back 12 of the belts 10, 11 facing away from the fleece 5, there is a sliding coating 16 in the entire pressing area 13, which consists of a pre-pressing area 14 and a main pressing and calibration area 15, for example a rubber vulcanized onto an abutment 17 in the pressing area 13 can be.

Im Vorpreßbereich 14 verlaufen die Gleitbeläge 16 unter Bildung eines sich verengenden Preßspaltes winklig zueinander. Die jeweiligen Gleitbeläge 16 können bevorzugt aus Gleitbelagsmodulen bestehen, die winkelmäßig gegeneinander versetzt in Transportrichtung 81 der Bänder 10, 11 aufeinanderfolgen und schließlich im Hauptpreßbereich parallel zueinander verlaufend angeordnet sind.In the pre-pressing area 14, the sliding linings 16 run at an angle to one another, forming a narrowing press gap. The respective sliding linings 16 can preferably consist of sliding lining modules which follow one another angularly offset in the transport direction 81 of the belts 10, 11 and are finally arranged parallel to one another in the main pressing area.

Es ist auch möglich, daß der Gleitbelag 16 im Vorpreßbereich bis zu dem Beginn des Hauptpreßbereichs 15 stetig bzw. kontinuierlich gekrümmt ausgebildet ist.It is also possible for the sliding coating 16 to be designed to be continuously or continuously curved in the pre-pressing area up to the beginning of the main pressing area 15.

Presseneingangsseitig ist über dem Vlies 5 eine Vorrichtung 19 mit Rollen 20, 21 vorgesehen, von denen ein profiliertes Band 22 abgezogen und auf die Oberfläche des Vlieses geleitet werden kann. Die beiden Rollen 20, 21 sind insbesondere deshalb vorgesehen, um zwischen den Rollen einen fliegenden Wechsel und damit einen kontinuierlichen Betrieb der Gesamtanlage vornehmen zu können.On the press input side, a device 19 with rollers 20, 21 is provided above the fleece 5, from which a profiled strip 22 can be pulled off and guided onto the surface of the fleece. The two rollers 20, 21 are provided in particular in order to be able to make a flying change between the rollers and thus continuous operation of the overall system.

Das Vlies 5 und das auf der Vliesoberfläche liegende Band 22 durchwandern zusammen und synchron den Preßspalt, wobei durch das profiliert ausgebildete Band 22 und/oder durch die Bänder 10, 11 der Doppelband-Fertigpresse der Plattenbahn 1 dekorative Vorsprünge und Ausnehmungen, z.B. in Gestalt einer Sandsteinstruktur oder einer Schieferung, verliehen werden. Pressenausgangsseitig wird das profilierte Band 22 in eine Vorrichtung 23 überführt, bzw. mittels dieser Vorrichtung 23 von der Plattenbahn 1 abgenommen. Diese Vorrichtung 23 besteht wiederum aus zwei Rollen 24, 25, zwischen denen ein fliegender Wechsel durchführbar ist.The fleece 5 and the belt 22 lying on the fleece surface migrate together and synchronously through the press nip, with the profiled belt 22 and / or the belts 10, 11 of the double-belt finishing press of the plate web 1 decorative protrusions and recesses, for example in the form of a sandstone structure or slate, are awarded. On the press exit side, the profiled strip 22 is transferred to a device 23 or removed from the plate web 1 by means of this device 23. This device 23 in turn consists of two rollers 24, 25, between which a flying change can be carried out.

Anstelle der Verwendung eines profilierten Bandes 22 kann die Ausbildung dekorativer Vorsprünge und Ausnehmungen auch allein mittels des endlos umlaufenden Bandes 10 erfolgen, das in diesem Falle in der gewünschten Weise oberflächenprofiliert ist.Instead of using a profiled band 22, the formation of decorative projections and recesses can also be carried out solely by means of the endless band 10, which in this case is surface-profiled in the desired manner.

Nach einer Ausgestaltung der Erfindung kann der Doppelband-Fertigpresse zumindest ein Walzenpaar 26, 27 nachgeordnet sein, das zur Durchführung ergänzender Präge- und Profilierungsvorgängen dient.According to one embodiment of the invention, at least one pair of rollers 26, 27 can be arranged after the double-belt finishing press, which serves to carry out additional embossing and profiling processes.

Die Zeichnung zeigt ferner presseneingangsseitig Auftragsvorrichtungen 28, 29 für Lack oder Farbe. In dem dargestellten Ausführungsbeispiel sind diese Auftragsvorrichtungen 28, 29 unmittelbar dem Presseneingangsspalt vorgeordnet und für die Ober- und die Unterseite des Vlieses 5 vorgesehen. Es kann auch von Vorteil sein, die Auftragsvorrichtungen 28, 29 in größerem Abstand vom Eingangsspalt im Bereich der horizontal verlaufenden Bänder 10, 11 anzuordnen. Die Auftragswalzen 30, 31 übertragen die Lack- bzw. Farbmasse gleichmäßig auf die Außenflächen..des oberen und unteren endlos umlaufenden Bandes 10, 11. Selbstverständlich kann es in manchen Anwendungsfällen auch genügen, die Farb- bzw. Lackmasse auf eine Seite des Vlieses 5 aufzubringen.The drawing also shows application devices 28, 29 for lacquer or paint on the press input side. In the exemplary embodiment shown, these application devices 28, 29 are arranged directly upstream of the press inlet nip and are provided for the top and bottom of the fleece 5. It can also be advantageous to arrange the application devices 28, 29 at a greater distance from the entrance gap in the region of the horizontally running belts 10, 11. The application rollers 30, 31 transfer the lacquer or ink mass evenly to the outer surfaces .. of the upper and lower endless belt 10, 11. Of course, in some applications it may also be sufficient to apply the ink or lacquer mass to one side of the fleece 5 to apply.

Innerhalb des Preßspaltes verbindet sich die Farb- bzw. Lackmasse innig mit dem Vlies und wird während des Durchlaufs durch die Presse getrocknet und zumindest im wesentlichen gehärtet, wodurch im Auslaufbereich der Doppelband-Fertigpresse sich die umlaufenden Bänder 10, 11 im wesentlichen frei von irgendwelchen Farbresten von der fertigen Plattenbahn 1 trennen und demgemäß eine Plattenbahn von hochwertigem Aussehen erhalten wird.Within the press nip, the paint or lacquer mass connects intimately with the fleece and becomes during the run dried by the press and at least substantially hardened, as a result of which the peripheral belts 10, 11 in the outlet area of the double belt finishing press separate from the finished plate web 1 essentially free of any color residues and accordingly a plate web of high quality appearance is obtained.

Der Doppelband-Fertigpresse nach der Zeichnung können gegebenenfalls Vorpreß- zbw. Verdichtungswalzenpaare vorgeschaltet sein und/oder die presseneingangsseitig vorgesehenen Umlenkwalzen für die Bänder 10, 11 der Doppelband-Fertigpresse können gleichzeitig Preßwalzen zur Ausübung vorzugsweise eines Fertigpreßdruckes bilden, und es ist ferner in Abhängigkeit von den jeweils verwendeten Materialien von Vorteil, den Temperaturgradienten längs des Preßspaltes zu variieren, um optimale Verformungs- und Stabilisierungsbedingungen für das Vlies einstellen zu können.The double belt pre-press according to the drawing can optionally pre-press. Compaction roller pairs can be connected upstream and / or the deflection rollers for the belts 10, 11 of the double-belt finishing press provided on the press input side can simultaneously form press rollers for exerting preferably a finishing pressing pressure, and it is also advantageous, depending on the materials used in each case, to increase the temperature gradients along the pressing nip vary in order to be able to set optimal deformation and stabilization conditions for the fleece.
