Abstract

The board (10), in particular moulded fibre board, proposed is characterized in that it has at least one groove (40, 48) located at a fold line and making it possible to fold the board about the fold line. At least part of the groove (40, 48) is coated with adhesive (46) which bonds the two parts of the board together so that they can pivot. The method proposed for the manufacture of the foldable board is characterized in that the board is provided with a groove (40, 48) in the region of the fold line, the grooved board is provided with an additional groove lying opposite the first and having the same baseline. At least one of the grooves is coated with adhesive (46) which holds the two parts of the board together so that they can pivot. The installation for manufacturing the foldable board is characterized by at least one work station (22) which takes the board (10) to be machined and which has at least one device (33) designed to machine at least one groove (48) into the upper surface of the board, the work station holding, guiding and conveying the board at least in the vicinity of the machining device in such a way that it is free of vibration, plus at least one additional work station (6), following on from the first, which takes the board to be further processed and which has at least one device designed to machine in the board at least one groove (40) complementary to and facing each of the grooves made previously to permit the board to be folded, the work station holding, guiding and conveying the board at least in the vicinity of the machining device in such a way that it is free of vibration, plus at least one device designed to apply adhesive (46) in at least one of the grooves facing each other. The invention thus proposes a board, a method of manufacturing the board and an installation for carrying out the method in which it is possible to fold the visible surface (27, 35) of the board in on itself without the need to apply a strip of adhesive on the visible surfaceof the board, while at the same time ensuring high stability of the board in the opened state as well as low manufacturing costs.

Description

Die Erfindung betrifft eine Platte, insbesondere eine Hartfaserplatte, ein Verfahren zu deren Herstellung sowie eine Vorrichtung zur Herstellung von Platten, insbesondere von Hartfaserplatten, mit den Merkmalen des Oberbegriffs der Patentansprüche 1; 11 und 14.The invention relates to a plate, in particular one Hardboard, a process for making it as well a device for the production of plates, in particular of hardboard, with the features of the generic term of Claims 1; 11 and 14.

Bei der Herstellung von z. B. Schränken ist es üblich, als Rückwand eine sog. Hartfaserplatte zu benutzen, wobei bisher häufig die Sichtseite mit einer Kunststoffolie aus z. B. PVC veredelt war, so daß die dahinter befindliche aus Hartfasermaterial bestehende Rückseite entsprechend unterteilt werden konnte, um während der Weiterverarbeitung, der Lagerung oder des Transports z. B. zweiteilig gefaltet zu werden, so daß die Sichtseiten gegeneinander lagen, um bei Benutzung der Hartfaserplatte, d. h. dem Einbau z. B. in einen Schrank, auseinander gefaltet zu werden und dann im Schrank positioniert zu werden. In the manufacture of e.g. B. cupboards it is common as Back wall to use a so-called hardboard, so far often the visible side with a plastic film made of z. B. PVC was finished, so that the one behind it Hard fiber material existing back accordingly could be divided up during further processing, storage or transportation z. B. folded in two parts be so that the visible sides were against each other to Using the hardboard, d. H. the installation z. B. in a closet to be unfolded and then in the Cabinet to be positioned.

Durch die aufgebrachte Folie war eine derartige Faltung möglich, ohne daß nach einem Auseinanderfalten die Zweiteilung sichtbar war, vielmehr wurden die einzelnen Teile durch die Folie zusammengehalten.Such a fold was due to the applied film possible without having to unfold the Bifurcation was visible, rather the individual parts held together by the film.

Eine andere Möglichkeit der Platzersparnis bei Transport und Lagerung derartiger Hartfaserplatten war es, diese z. B. als zweiteilige Rückwand anzuliefern und über ein Kunststoffverbindungsstück miteinander vor Ort zu verbinden.Another way of saving space during transport and Storage of such hardboard was to z. B. as to deliver two-part back wall and one To connect plastic connector with each other on site.

Eine derartige Methode hat jedoch den Nachteil, daß sowohl bei der Herstellung als auch bei der Auslieferung verschiedene Teile gefertigt werden müssen und bei Einbau keine stabile Rückwand entsteht, da die Rückwandteile gegeneinader verschoben werden können und zwingend eine entsprechende Nagelung bzw. Befestigung der Rückwand an z. B. einem schrank notwendig ist, ohne daß dies zu einer wesentlichen Erhöhung der Stabilität der Rückwand und damit des gesamten Schrankes beiträgt.However, such a method has the disadvantage that both in the manufacture as well as in the delivery different parts have to be manufactured and during installation no stable back wall is created because the back wall parts can be moved against each other and mandatory one appropriate nailing or fastening the back wall to z. B. a closet is necessary without this substantial increase in the stability of the rear wall and thus of the entire cabinet.

Da es sich bei den Kunststoffolien um sog. PVC-Folien handelt, diese jedoch aus Umweltgründen nicht mehr benutzt werden sollten oder können, besteht das Problem, daß z. B. gelackte Rückwände nicht mehr wie bisher bei PVC-beschichteten Wänden durch eine mögliche Faltung gegen Beschädigung geschützt werden können, sondern vielmehr dadurch geteilt werden, daß auf der Rückseite der Hartfaserplatten im Teilungsbereich eine Klebefolie aufgebracht wird, um dann die beiden Rückseiten gegeneinander falten zu können.Since the plastic films are so-called PVC films acts, but is no longer used for environmental reasons should or can be, there is the problem that z. B. lacquered back walls no longer as previously with PVC-coated Walls against possible folding Damage can be protected, but rather be shared by the fact that on the back of the Hardboard in the division area an adhesive film is applied, then the two backs against each other to be able to fold.

Dies hat zum einen zur Folge, daß die Sichtseiten gesondert verpackt werden müssen, um eine Beschädigung während des Transports oder der Lagerung zu verhindern, da diese freiliegen, und zum anderen, daß nach einer Entfaltung und Einbau der Rückwand in z. B. einem Schrank eine unschöne und nicht gewollte Fuge verbleibt und überdies die Rückwand nicht die gewünschte Stabilität aufweist, da eine Verschiebung der einzelnen Teile gegeneinander möglich ist und der Schrank insgesamt durch entsprechende konstruktive Maßnahmen daher eine Erhöhung der Stabilität erfahren muß.On the one hand, this has the consequence that the visible sides are separate must be packed to prevent damage during the Prevent transportation or storage as this exposed, and secondly, that after an unfolding and Installation of the rear wall in z. B. a closet an unsightly and unwanted joint remains and, moreover, the rear wall does not has the desired stability, since a shift of the individual parts against each other is possible and the cabinet overall by appropriate design measures must experience an increase in stability.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Platte, insbesondere Hartfaserplatte, bereitzustellen, bei der eine Faltung in Richtung der Sichtflächen ohne Verwendung eines auf die Sichtfläche aufzubringenden Klebestreifens möglich ist und dies bei gleichzeitig hoher Stabilität der Platten im auseinandergefalteten Zustand und gleichzeitig geringen Erstellungskosten.The invention is therefore based on the object of a plate, in particular hardboard, to provide one Folding in the direction of the visible surfaces without using a adhesive tape to be applied to the visible surface is and this with high stability of the plates in unfolded condition and low at the same time Creation costs.

Diese Aufgabe wird in Hinsicht auf die Platte, insbesondere Hartfaserplatte, der eingangs geannten Gattung mit den Merkmalen des kennzeichnenden Teiles des Patentanspruchs 1; in Hinsicht auf das erfindungsgemäßen Verfahren der eingangs genannten Gattung mit den Merkmalen des kennzeichnenden Teiles des Patentanspruchs 13 und/oder in Hinsicht auf die Anlage der eingangs genannaten Gattung mit den Merkmalen des kennzeichnenden Teiles des Patentanspruchs 16 gelöst.This task is done with respect to the plate, in particular Hardboard, the type mentioned at the beginning with the Features of the characterizing part of claim 1; with regard to the method of the beginning mentioned genus with the characteristics of the characteristic Part of claim 13 and / or in relation to the Creation of the initially mentioned genre with the characteristics of characterizing part of claim 16 solved.

Vorteilhafte Ausgestaltungen der Erfindungen sind Gegenstand der Unteransprüche 2 bis 12; 14 und 15 bzw. 17 bis 37.Advantageous embodiments of the inventions are the subject of subclaims 2 to 12; 14 and 15 or 17 to 37.

Dadurch, daß wenigstens eine eine Faltung der Platte um eine Schwenkachse ermöglichende und im Bereich der Schwenkachse angeordnete Nut vorgesehen ist und daß die Nut mit einem die faltbaren Plattenteile verschwenkbar verbindenden Kleber versehen ist, wird die Möglichkeit geschaffen, eine Platte, insbesondere Hartfaserplatte, derart falten zu können, daß die zu schützenden Sichtseiten gegeneinanderliegend gelagert und/oder transportiert werden können, ohne daß ein Klebestreifen auf die Nut aufgebracht werden müßte, sondern es wird vielmehr eine Platte geschaffen, die nach Entfaltung eine hohe Seitenstabilität aufweist. The fact that at least one folds the plate by one Allowing swivel axis and in the area of the swivel axis arranged groove is provided and that the groove with a foldable plate parts pivotally connecting adhesive is provided, the possibility is created of a plate, in particular hardboard, to be able to fold such that the visible sides to be protected are stored opposite each other and / or can be transported without a Adhesive strips should be applied to the groove, but rather, a plate is created that, after unfolding has a high lateral stability.

Sind zwei eine Faltung der Platte um eine Schwenkachse ermöglichende und im Bereich der Schwenkachse angeordnete Nuten vorgesehen, sind darüber hinaus die Nuten einander gegenüberliegend angeordnet und ist wenigstens eine der Nuten mit einem die zu faltenden Plattenteile verschwenkbar verbindenen Kleber versehen, so ermöglicht dies eine optimale Verschwenkbarkeit der Platten, ohne daß es hierbei zu einem erhöhten Auftrag im Bereich der Schwenkachse kommt, d. h. die Platten können weitgehend plan gegeneinander gelegt und bei Bedarf auseinandergefaltet werden, ohne daß hierzu weitere technische Hilfsmittel vonnöten sind.Are two a folding of the plate around a pivot axis enabling and arranged in the region of the pivot axis Grooves provided, the grooves are also each other arranged opposite and is at least one of the grooves with one the plate parts to be folded can be pivoted connecting adhesive, so this enables an optimal Swiveling of the plates, without this becoming one increased order comes in the area of the swivel axis, d. H. the Panels can be placed flat against each other and largely Unfolded as needed without this technical aids are required.

Ist eine der Nuten mit einem die zu faltenden Plattenteile verschwenkbar verbindenen Kleber versehen und ist wenigstens eine der Nuten trapezförmig ausgestaltet, so erleichtert dies die Faltbarkeit der erfindungsgemäßen Platte.Is one of the grooves with one of the plate parts to be folded provided pivotally connecting adhesive and is at least one of the grooves is trapezoidal, so this facilitates the foldability of the plate according to the invention.

Ist die mit einem die zu faltenden Plattenteile verschwenkbar verbindenen Kleber versehene Nut trapezförmig ausgestaltet, so wird dadurch die Möglichkeit geschaffen, trotz eines relativ geringen Auftrags des Klebers eine haltbare Verbindung der Plattenteile untereinander zu schaffen.Is it pivotable with one of the plate parts to be folded connecting groove provided trapezoidal adhesive, this creates the possibility, despite one relatively low application of the adhesive a durable To create a connection between the plate parts.

Sind die einander gegenüberliegend angeordneten Nuten trapezförmig ausgestaltet und sind die Nuten eine gemeinsame Grundlinie aufweisend zueinander angeordnet, so ermöglicht dies eine Lage der Schwenkachse nahe der Sichtfläche der Platten und damit eine einfache und unkomplizierte Faltungsmöglichkeit der Plattenteile.Are the grooves arranged opposite each other designed trapezoidal and the grooves are a common one Baseline arranged to each other, so enables this is a position of the pivot axis near the visible surface of the Plates and thus a simple and uncomplicated Possibility of folding the plate parts.

Ist die der den Kleber aufweisende Nut gegenüberliegend angeordnete Nut der Plattensichtfläche zugeordnet und ist sie mit einer an die Farbe der Sichtfläche angepaßten elastischen Masse wenigstens teilweise gefüllt, so wird dadurch zum einen eine erhöhte Haltbarkeit der zu faltenden Plattenteile gewährleistet, d. h. auch eine mehrfache Faltung und Entfaltung der Plattenteile führt nicht zu einem Verlust der Haltbarkeit der Plattenteilverbindung und zum anderen führt diese Ausgestaltung dazu, daß im Sichtbereich der z. B. Schrankrückwand keine ungewollte Unterbrechung der Sichtfläche entsteht, sondern vielmehr der Eindruck einer geschlossenen Fläche geschaffen wird.Is the groove opposite the adhesive arranged groove of the panel face and is assigned with an elastic that matches the color of the visible surface Mass is at least partially filled, so on the one hand increased durability of the panel parts to be folded guaranteed d. H. also a multiple folding and Unfolding the plate parts does not lead to a loss of Durability of the plate part connection and leads to the other this configuration to the fact that in the field of view of z. B. Cabinet rear wall no unwanted interruption of the Visible area is created, but rather the impression of a closed area is created.

Weist die der Sichtfläche zugeordnete Nut eine Tiefe von 0,1 bis 0,3 Milimeter, vorzugsweise 0,1 Milimeter, auf, so wird dadurch eine Klappbarkeit bzw. Faltbarkeit der Plattenteile erreicht, ohne daß von einem Auftrag der zueinander zu faltenden Plattenteile im Bereich der Faltung gesprochen werden kann.If the groove assigned to the visible surface has a depth of 0.1 to 0.3 millimeters, preferably 0.1 millimeters, so thereby a foldability or foldability of the plate parts achieved without having to give each other an order folding plate parts spoken in the area of folding can be.

Ist der Kleber ein Polyuretankleber, so wird dadurch ein äußerst haltbarer und für die hier vorliegende Verwendung geeigneter Kleber gewählt.If the adhesive is a polyurethane adhesive, it becomes a extremely durable and for the present use suitable glue selected.

Anzumerken ist, daß der Kleber nur zum Zwecke der Faltbarkeit der Platten dient; ein Verkleben sich anläßlich des Positionierens beim Zusammenbau in Berührung tretender kleberbeschichteter Flächen ist weder beabsichtigt noch zu erwarten, weil der Kleber eine Scharnierfunktion hat, die auch nach Zerlegen eines mit den erfindungsgemäßen Platten montierten Möbels weiterhin nutzbar ist.It should be noted that the adhesive is only for the purpose of foldability the plates serve; a sticking on the occasion of the Positioning in contact when assembling adhesive-coated surfaces are neither intended nor closed expect because the adhesive has a hinge function that even after disassembling one with the plates according to the invention assembled furniture is still usable.

Die Faltbarkeit der Platten ist beim Transport von großem Nutzen, wenn sich die Breite dieser Platten auf die Hälfte oder auf ein Viertel falten läßt.The foldability of the panels is great during transport Benefit if the width of these panels is half or folds to a quarter.

Dadurch, daß bei dem erfindungsgemäßen Verfahren die Platte im Faltungsbereich mit einer Nut versehen wird, die mit einer Nut versehenen Platte mit einer weiteren gegenüberliegend angeordneten und mit der ersten Nut eine gemeinsame Grundlinie aufweisenden Nut versehen wird und daß wenigstens eine der Nuten mit einem die Plattenteile verschwenkbar zueinander haltenden Kleber versehen wird, wird auf einfachste Art und Weise, d. h. ohne großen konstruktiven technischen Aufwand, ein Verfahren bereitgestellt, das eine Faltbarkeit von Platten, insbesondere Hartfaserplatten, ermöglicht, ohne daß optische oder technische Nachteile wie Instabilität oder Unterbrechung der Sichtflächen entstehen.The fact that in the method according to the invention the plate in the folding area is provided with a groove that with a Grooved plate with another opposite arranged and a common with the first groove Groove having baseline is provided and that at least one of the grooves with the plate parts pivotable Adhesive holding each other is provided on easiest way, d. H. without great constructive technical effort, a procedure provided that a Foldability of boards, especially hardboard, enables without optical or technical disadvantages like There is instability or interruption of the visible surfaces.

Wird die Platte im Faltungsbereich an ihrer Sichtseite mit einer trapezförmig ausgestalteten Nut versehen und wird in die Nut ein elastisches Material eingebracht und die mit einer Nut versehene Platte mit einer weiteren gegenüberliegend angeordneten und trapezförmig ausgestalteten und mit der gegenüberliegend angeordneten Nut eine gemeinsame Grundlinie aufweisenden weiteren Nut versehen und darüber hinaus in diese Nut ein PUR-Kleber eingebracht, so wird dadurch eine faltbare Platte, wie z. B. Hartfaserplatte, geschaffen, die sich zum einen durch hohe Stabilität, zum anderen durch eine einfache Lagerungs- und Transportmöglichkeit und zum dritten durch eine optisch ansprechende, da nicht unterteilte Sichtfläche auszeichnet.If the plate is in the folding area on its visible side a trapezoidal groove and is in the groove introduced an elastic material and the with a grooved plate with another oppositely arranged and designed trapezoidal and a common one with the groove arranged opposite Provide another groove with the baseline and above A PUR adhesive is introduced into this groove thereby a foldable plate, such as. B. hardboard, created, on the one hand by high stability, on the other others through a simple storage and Transport option and thirdly by an optical appealing, as it is not divided into visible areas.

Wird die Platte zunächst im Bereich in der auf der Sichtseite einzubringenden Nut vor Einbringen dieser Nut erwärmt und wird in die Nut ein elastisches Material in einem weiteren Arbeitsschritt eingebracht und darüber hinaus der in die gegenüberliegend angeordnete Nut eingebrachte Kleber in einem weiteren sich an die Einbringung des Klebers anschließenden Arbeitsschritt durch Kühlen mit Flüssigkeit ausgehärtet, so wird dadurch insgesamt sichergestellt, daß zum einen bei der Bearbeitung von z. B. mit einer Farbschicht bespritzten Hartfaserplatten diese Farbschicht nicht reißt und zum anderen die Möglichkeit geschaffen, entsprechende Platten in einem Arbeitsverfahren herstellen zu können, ohne daß es zu Zwischenlagerungen oder ähnlichen den Arbeitsprozeß unterbrechenden Arbeitsschritten kommt.First the panel is in the area on the visible side groove to be introduced and heated before inserting this groove becomes an elastic material in another in the groove Work step introduced and beyond that in the opposing groove inserted glue in one others following the introduction of the adhesive Work step hardened by cooling with liquid, see above is thereby ensured overall that, on the one hand, at the Editing of e.g. B. sprayed with a layer of paint Hardboard does not tear this layer of paint and to others created the opportunity to put in appropriate plates to be able to produce a working process without it Temporary storage or similar the work process interrupting work steps.

Ist wenigstens eine die zu bearbeitende Platte aufnehmende und wenigstens eine wenigstens eine Nut in die Plattenoberseite einfräsende Fräsvorrichtung aufweisende und die Platten wenigstens im Bereich der Fräsvorrichtung schwingungsarm haltende, führende und transportierende Arbeitsstation vorgesehen ist, darüber hinaus wenigstens eine weitere sich daran anschließende, eine die weiter zu bearbeitende Platte aufnehmende und wenigstens eine einer jeden der Faltbarkeit der Platte dienende, vorher eingebrachten Nut gegenüberliegende, komplementär dazu ausgebildete Nut in die Platte einfräsende Fräsvorrichtung aufweisende und die Platte wenigstens im Bereich der Fräsvorrichtung schwingungsarm haltende, führende und transportierende weitere Arbeitsstation vorgesehen und ist wenigstens eine einen Kleber in wenigstens jeweils eine der gegenüberliegend angeordneten Nuten einbringende Vorrichtung vorgesehen, so wird dadurch eine Anlage zur Herstellung von faltbaren Platten, insbesondere Hartfaserplatten, bereitgestellt, mit der diese faltbaren Platten geschaffen werden können, ohne daß hierzu jeweils Umrüst-, Nachrüst- oder separate firmeninterne Transporte notwendig sind.Is at least one plate to be machined and at least one at least one groove in the Milling device with milling device on the top and the plates at least in the area of the milling device low-vibration, leading and transporting Workstation is provided, in addition at least one more subsequent, one that continues to processing plate receiving and at least one one each before serving the foldability of the plate inserted groove opposite, complementary to it trained groove in the plate milling device having and the plate at least in the area of Milling device holding, leading and low vibration transporting further work station is provided and is at least one an adhesive in at least one of each oppositely arranged grooves introducing device provided, a plant for the production of foldable sheets, especially hardboard, provided with which these foldable panels are created can be without retrofitting, retrofitting or separate company-internal transports are necessary.

Darüber hinaus wird durch die erfindungsgemäße Anlage, insbesondere durch die Schwingungsarmut der Platte im Bereich der entspechenden Stationen, erreicht, daß die zu fräsenden und veredelnden Nuten auch bei dünnen z. B. Hartfaserplatten mit einer äußerst hohen Präzisität geschaffen werden können.In addition, the system according to the invention, especially due to the low vibration of the plate in the area of the corresponding stations, achieved that the to be milled and finishing grooves even with thin z. B. hardboard can be created with extremely high precision.

Sind die den Kleber in die Nut einbringende und die komplementär zur ersten ausgestalteten gegenüberliegend angeordnete Nut fräsende Vorrichtung in einer Arbeitsstation angeordnet, so wird dadurch eine kompakte Arbeitsstation bereitgestellt, die sich durch eine hohe Effektivität und geringen Platzbedarf auszeichnet.Are they the glue in the groove and the complementary to the first configured opposite arranged groove milling device in a work station arranged, so it becomes a compact workstation provided, which is characterized by a high effectiveness and low space requirements.

Schließt sich an die die Vorrichtung zur Einbringung des Klebers aufweisende Arbeitsstation eine Kleberaushärtestation an, so trägt auch dies zur Kompaktheit und damit zur Effektivität der gesamten Anlage bei. Connects to the device for introducing the Glue-containing work station an adhesive curing station , this also contributes to compactness and thus to Effectiveness of the entire system.

Weist die Klebeaushärtestation eine Kühl- und/oder Aushärteflüssigkeit an den Kleber gebende Vorrichtung auf, so wird dadurch der Kleber in optimaler Weise in kürzester Zeit voll ausgehärtet, so daß zum einen diese Station äußerst kurz gehalten werden kann und zum anderen die die Station verlassenden Platten nicht erst zwischengelagert werden müssen, sondern direkt einer eventuellen Weiterverarbeitung oder Verschickung zugeführt werden können.The adhesive curing station has a cooling and / or Hardening liquid to the adhesive-giving device, see above the glue becomes optimal in the shortest possible time fully hardened, so that this station is extremely short and the station leaving plates are not first stored must, but directly a possible further processing or dispatch can be supplied.

Ist in Transportrichtung der Platten vor der die Plattenoberseite mit wenigstens einer Nut versehenden Arbeitsstation eine Plattenaufwärmstation angeordnet und ist die Plattenaufwärmstation die Platten im Bereich der zukünftigen Nut aufwärmend ausgestaltet, so wird dadurch eine optimale Vorbereitung der Platten erreicht, d. h. es wird sichergestellt, daß es beim Einfräsen der Nut nicht zu Rissen oder anderen Beschädigungen der Oberfläche, insbesondere des Lackes, kommt.Is in the direction of transport of the plates in front of the Provide the top of the plate with at least one groove Workstation a plate warm-up station is arranged the plate heating station the plates in the area of designed future groove warming, so it is a optimal preparation of the plates achieved, d. H. it will ensures that there are no cracks when milling the groove or other damage to the surface, especially the Lackes, comes.

Durch die Ausgestaltung der Aufwärmstation mit IR-Strahlern wird eine Technik gewählt, die sich durch eine hohe Zuverlässigkeit bei geringen Kosten auszeichnet.By designing the warm-up station with IR radiators a technology is chosen that is characterized by a high Reliability at low cost.

Schließt sich an die eine Vorrichtung zur Abgabe eines elastischen Materials aufweisende Arbeitsstation eine das elastische Material trocknende weitere Arbeitsstation an, so wird auch hier erreicht, daß keine Zwischenlagerung der Platten zur Trocknung des eingebrachten elastischen Materials notwendig ist, sondern die Platten vielmehr in einem Arbeitsgang weiter bearbeitet werden können.Connects to a device for dispensing a work station having elastic materials elastic material drying further work station, so is also achieved here that no intermediate storage of the Sheets for drying the inserted elastic material is necessary, but rather the plates in one Operation can be processed further.

Sind die Arbeitsstationen die einzelnen zu bearbeitenden Platten unter Vorschub transportierend ausgestaltet und weist die Aufwärm-, Trocken- und Kühlstation jeweils mit der Plattenoberseite über das jeweilige Untertrum in Wirkungseingriff stehende und diese mit einem Vorschub versehende Riementriebe und darüber hinaus zwei die Platten auf ihrer Unterseite abstützenden koaxial zum jeweiligen Untertrum der Riementriebe angeordnete Gleitschienen auf, so wird dadurch ein Vorschub der Platten sichergestellt, der sich durch hohe Betriebssicherheit bei gleichzeitig geringer Störanfälligkeit und lohnenden Transport der zu bearbeitenden Platten auszeichnet.Are the workstations the individual to be machined Plates designed and transported under feed the warming up, drying and cooling station with the Top of the board over the respective lower run in Intervention and this with a feed provided belt drives and in addition two the plates supporting on its underside coaxial to the respective Sliding rails arranged below the belt drives, see above This ensures that the plates are fed thanks to high operational safety and at the same time less Susceptibility to failure and worthwhile transport of the processed Plates.

Sind die Gleitschienen unter Vorspannung gegen die Unterseite der Platte drückend angeordnet, so wird auch bei entsprechenden Toleranzen oder verschieden starken Platten sichergestellt, daß es zu keinen Stillständen der Anlage oder aufwendigen Nachrüstarbeiten kommen muß.Are the slide rails pre-stressed against the underside the plate is arranged in a pushing manner, so is also at corresponding tolerances or different thickness plates ensures that there are no plant downtimes or elaborate retrofitting must come.

Sind die wenigstens eine Fräsvorrichtung und/oder elastisches Material abgebende Vorrichtung aufweisende Arbeitsstation und die wenigstens eine die Fräsvorrichtung und/oder eine Klebeabgabevorrichtung aufweisende Arbeitsstation die einzelnen Platten unter Vorschub transportierend ausgestaltet, und weist jede dieser Arbeitsstationen zwei mit der Unterseite der jeweiligen Platten über das jeweilige Obertrum in Wirkungseingriff gelangende Riementriebe auf, sind mit der Plattenoberseite in Kontakt gelangende und als Gegenlager wirkende Rollenkörper vorgesehen und sind darüber hinaus auf der der Platte abgewandten Seite des jeweiligen Obertrums unter Vorspannung gegen das Obertrum drückende Gleitschienen angeordnet, so wird dadurch auf ebenso einfache aber um so wirkungsvollere Weise eine weitgehend vibrationsfreie Bearbeitung der Platten ermöglicht, da diese unter Vorspannung gegen die darüber befindlichen Rollenkörper gedrückt werden.Are the at least one milling device and / or elastic Material dispensing device and workstation the at least one the milling device and / or one Workstation having adhesive dispensing device transporting individual plates under feed designed, and each of these workstations with two the underside of the respective plates over the respective Belt drives coming into action on the upper run, are in contact with the top of the plate and as Counter-bearing roller bodies are provided and are above on the side facing away from the plate Upper run under tension against the upper run Slideways arranged, it will be just as easy but the more effective one largely Vibration-free processing of the plates enables, as this under tension against the roll bodies above be pressed.

Sind die Gleitschienen federnd gelagert, so wird darüber hinaus sichergestellt, daß diese vibrationsfreie Bearbeitung auch bei unterschiedlich starken Platten gewährleistet ist.If the slide rails are spring-loaded, it is above also ensures that this vibration-free machining even with different thickness plates is guaranteed.

Überspannen die außerhalb der Bearbeitungsbereiche in den Arbeitsstationen angeordneten Rollenkörper den Bereich der zu bearbeitenden oder zu schaffenden Nut und enden die Rollenkörper mit ihren Enden in einem Abstand dazu, so verhindert dies in optimaler Weise eine ungewollte Vibration der zu bearbeitenden Platten.
Sind die im Bearbeitungsbereich der Stationen angeordneten Rollenkörper zweiteilig ausgestaltet und mit ihren einander zugewandten Enden in einem Abstand zueinander den Bearbeitungsbereich freigebend, ausgestaltet, so wird dadurch sichergestellt, daß eine kontinuierliche Bearbeitung der Platten gewährleistet ist, dies bei gleichzeitger vibrationsfreier Anordnung der Platten und kontinuierlichem Vorschub der Platten.If the roller bodies arranged outside the processing areas in the workstations span the area of the groove to be machined or created and the ends of the roller bodies end at a distance from it, this optimally prevents unwanted vibration of the panels to be machined.
If the roller bodies arranged in the machining area of the stations are designed in two parts and their mutually facing ends at a distance from one another are designed to enable the machining area, this ensures that continuous machining of the plates is ensured, with simultaneous vibration-free arrangement of the plates and continuous feed of the plates.

Ist die Klebeabgabevorrichtung in ihrer Lage zur Transportrichtung parallel zu dieser verlagerbar angeordnet, so werden etwaige geringe Lageveränderungen der Nut, die im z. B. 0,1-Milimeter-Bereich liegen können, ausgeglichen und eine kontinuierliche Versorgung der Nut mit dem Kleber sichergestellt.Is the glue dispenser in position for Transport direction arranged to be displaceable parallel to this, so any small changes in position of the groove, which in e.g. B. 0.1-millimeter range, balanced and a continuous supply of the groove with the adhesive ensured.

Ist ein den Kleber in die Nut einbringender Kleberabgabeschuh vorgesehen, ist der Schuh wenigstens teilweise beheizbar, weist der Schuh einen vertikal verstellbaren Führungsteil auf und ist der Schuh unter Vorspannung in der mit Kleber zu versehenden Nut bei Vorschub der Platte in der Nut gleitend angeordnet, so wird dadurch zum einen erreicht, daß die Stärke des Klebers auf einfachste Art und Weise variabal einstellbar ist und zum anderen, daß der Kleber im optimalen Temperaturbereich in die Nut eingebracht wird und auch bei kontinuierlichem Vorschub ausreichend Kleber in die Nut gelangt.Is a glue dispenser shoe that brings the glue into the groove provided, the shoe is at least partially heatable, the shoe has a vertically adjustable guide part and the shoe is under tension in the glue too provided groove slides in the groove when the plate is fed arranged, it is achieved on the one hand that the The thickness of the adhesive is variable in the simplest way is adjustable and on the other hand that the adhesive in the optimal Temperature range is introduced into the groove and also at continuous feed of sufficient glue into the groove reached.
