Description

Die Erfindung betrifft ein Verfahren zur Durchlauf-Bearbeitung von plattenförmigen Produkten aus Holz, Holzwerkstoffen oder artverwandten Produkten.The invention relates to a method for continuous processing of plate-shaped Products made of wood, wood-based materials or related products.

Die Format- und Kantenbearbeitung im kontinuierlichen Durchlauf auf verketteten Anlagen und auf hohem Automatisierungsniveau ist in der Holzbe- und -verarbeitenden Branche und artverwandten Branchen bekannt. Hier werden Platten bei hoher Mengenleistung, je nach Erfordernis und Anwendungsfall z. B. formatiert, die Schmalflächen mit verschiedensten Kantenmaterialien beschichtet und nachbearbeitet. Der Plattentransport erfolgt kontinuierlich, wobei die erreichbare Vorschubgeschwindigkeit von der Art des zu bearbeitenden Materials, der Bearbeitungsaufgabe und den Nachbearbeitungsaggregaten abhängig ist. Ferner ist auch die Bohr- und Stationärfräsbearbeitung [Einbringen von Bohrungen für z. B. Verbindungsbeschläge, Dübellochbohrungen, Türbeschläge oder auch Fräsungen für Schlösser usw.] auf sogenannten Durchlaufbohr- und Fräsautomaten im Quer-Durchlauf nach dem Durchlauftakt-Prinzip bekannt. Der Plattentransport erfolgt durch Riemenförderer im Takt. Das heißt, es wird jeweils eine Platte in die Bearbeitungsstation gefördert, der Vorschub gestoppt, die Platte ausgerichtet, gespannt, die Bearbeitung durchgeführt, entspannt und schließlich ausgefördert.Format and edge processing in a continuous pass on chained Plants and at a high level of automation is in the woodworking and -processing industry and related industries known. Here are plates at high volume output, depending on the requirement and application z. B. formatted the Narrow surfaces coated with a wide variety of edging materials and reworked. The plate transport takes place continuously, the achievable Feed speed depending on the type of material to be processed, the Processing task and the post-processing units is dependent. Furthermore is also drilling and stationary milling [making holes for z. B. Connection fittings, dowel holes, door fittings or milling for Locks etc.] on so-called continuous drilling and milling machines in cross-pass known according to the cycle clock principle. The plates are transported by Belt conveyor in time. That means there will be one plate in each Processing station conveyed, the feed stopped, the plate aligned, excited, the processing carried out, relaxed and finally promoted.

Aufgrund der Vielzahl von durchzuführenden Operationen ist die mögliche Taktleistung begrenzt. Sie liegt in der Praxis je nach Bearbeitungsaufgabe bei ca. 12 - 25 Takten/min.Due to the multitude of operations to be performed, the possible cycle power is limited. In practice, depending on the processing task, it is approx. 12 - 25 Cycles / min.

Mit den oben genannten Format- und Kantenbearbeitungsanlagen ist bei vielen Anwendungsfällen eine wesentlich höhere Mengenleistung möglich, weshalb die erstrebenswerte Komplettbearbeitung [Format- und Kantenbearbeitung einschließlich Bohr- und Stationärfräsbearbeitung] innerhalb einer Fertigungslinie nicht sinnvoll realisiert werden kann, da die Möglichkeiten der Format- und Kantenbearbeitungsanlagen hierdurch unzulässig eingeschränkt würden. Daher wird die Bohr- und Stationärfräsbearbeitung in der Regel außerhalb der "Linie" auf separaten Einzelmaschinen durchgeführtWith the format and edge processing systems mentioned above is with many Applications a much higher volume output possible, which is why desirable complete machining [format and edge machining including Drilling and stationary milling] not useful within a production line can be realized because of the possibilities of format and Edge processing systems would be impermissibly restricted as a result. Therefore drilling and stationary milling generally outside the "line" carried out separate individual machines

Es ist daher Aufgabe der vorliegenden Erfindung, die Mengenleistung bei der Bohr- und Stationärfräsbearbeitung so zu erhöhen, daß eine Integration dieser Bearbeitungen in eine Fertigungsstraße für die Format- und Kantenbearbeitung, ohne unzulässige Einschränkung der hier möglichen Mengenleistung und unter Berücksichtigung spezifischer Branchen- und Werkstoffanforderungen möglich ist. Die spezifischen Anforderungen sind vielfältig, so sind beispielsweise bei furnierten Platten häufig die späteren "Sichtseiten" mit hochwertigerem Furnier belegt als die "Innenseiten", oder nicht sichtbare Flächen nur mit einem Gegenzugpapier, welches häufig Materialschüsselungen zur Folge hat. Die große Zahl unterschiedlicher Holzarten und Beschichtungen mit unterschiedlichen physikalischen Eigenschaften, der nicht homogene Aufbau des Holzes und die damit verbundenen Formveränderungen sind weitere Faktoren, die ihre Berücksichtigung beim Verfahren gemäß dieser Erfindung finden sollen.It is therefore an object of the present invention to increase the quantity output in drilling and stationary milling such that an integration of these operations in a production line for format and edge processing without unacceptable limitation of the quantity output possible here and taking into account specific industry and material requirements is possible. The specific requirements are diverse, for example in the case of veneered panels, the later " visible sides" are often covered with higher quality veneer than the "inner sides", or invisible surfaces are only covered with a backing paper, which often results in material keying. The large number of different types of wood and coatings with different physical properties, the non-homogeneous structure of the wood and the associated changes in shape are further factors which should be taken into account in the method according to this invention.

Diese Aufgabe wird bei einem Verfahren zur Quer-Durchlauf-Bearbeitung von plattenförmigen Produkten aus Holz, Holzwerkstoffen oder artverwandten Produkten durch folgende Verfahrensschritte gelöst :

  • a. die quer zugeführten Platten werden so in einem Magazin zwischengepuffert, daß die zu bearbeitenden Flächen im Wechsel unten/oben liegen,
  • b. zwei übereinanderliegende Platten werden in Richtung des Querdurchlaufes formschlüssig gemeinsam so einer Bohr- und/oder Frässtation zugeführt, daß die zu bearbeitenden Flächen außen liegen,
  • c. die übereinanderliegenden Platten werden in einem einzigen Spanntakt gemeinsam und gleichzeitig an ihren außenliegenden Flächen und/oder ihren Schmalseiten bearbeitet, und
  • d. die einseitig bearbeiteten Platten werden vereinzelt.
    • This task is solved in a process for the cross-pass processing of plate-shaped products made of wood, wood-based materials or related products by the following process steps:
  • a. the transversely fed plates are buffered in a magazine in such a way that the surfaces to be processed are alternately below / above,
  • b. two superposed plates are positively fed together in the direction of the cross pass to a drilling and / or milling station in such a way that the surfaces to be machined are on the outside,
  • c. the superimposed plates are processed together in a single clamping cycle and simultaneously on their outer surfaces and / or their narrow sides, and
  • d. the plates processed on one side are separated.

    • Infolge dieser Ausgestaltung können immer zwei Platten gleichzeitig bearbeitet werden wodurch eine höhere Mengenleistung erzielt werden kann. Dies erlaubt eine sinnvolle Integration der Bohr- und Stationärfräsbearbeitung in die bekannten, kontinuierlich arbeitenden Fertigungsstraßen für die Format- und Kantenbearbeitung. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen. As a result of this configuration, two plates can always be processed at the same time whereby a higher volume output can be achieved. This allows a reasonable one Integration of drilling and stationary milling in the known, continuous working production lines for format and edge processing. Advantageous further developments result from the subclaims.

    Sofern aus konstruktiven Gründen, z. B. wegen Platzmangels in einer ersten, die Verfahrensschritte nach Patentanspruch 1 ausführenden Bearbeitungsvorrichtung, eine erneute Bearbeitung der bereits bearbeiteten Flächen erforderlich ist, können in vorteilhafter Weiterbildung der Erfindung die folgenden Schritte durchgeführt werden:

  • a. nach dem Vereinzeln der Platten werden die Platten erneut so in einem Magazin zwischengepuffert, daß die bereits bearbeiteten Flächen jeweils unten/oben liegen,
  • b. zwei übereinanderliegende Platten werden gemeinsam so einer Bohr- und/oder Frässtation zugeführt, daß die zu bearbeitenden Flächen außen liegen,
  • c. die übereinanderliegenden Platten werden in einer zweiten Bohr- und/oder Frässtation in einem Takt gemeinsam und gleichzeitig an ihren außenliegenden Flächen und/oder ihren Schmalflächen bearbeitet, um weitere Bohr- und/oder Fräsvorgänge durchzuführen, und
  • d. die bearbeiteten Platten werden vereinzelt.
    • If for structural reasons, e.g. B. due to a lack of space in a first processing device carrying out the method steps according to claim 1, a new processing of the previously processed surfaces is required, the following steps can be carried out in an advantageous development of the invention:
  • a. after the plates have been separated, the plates are buffered again in a magazine so that the surfaces that have already been processed are located below / above,
  • b. two plates lying one above the other are jointly fed to a drilling and / or milling station such that the surfaces to be machined are on the outside,
  • c. the superimposed plates are processed in a second drilling and / or milling station together and simultaneously on their outer surfaces and / or their narrow surfaces in order to carry out further drilling and / or milling operations, and
  • d. the processed plates are separated.

    • Wenn die plattenförmigen Werkstücke auf beiden Seiten bearbeitet werden sollen, sind vorteilhafterweise die folgenden Verfahrensschritte vorgesehen:

  • a. im Falle einer beidseitigen Flächenbearbeitung werden die Platten erneut so in einem Magazin zwischengepuffert, daß die zuvor bearbeiteten Flächen jeweils im Wechsel oben/unten liegen,
  • b. zwei übereinanderliegende Platten werden so einer Bohr- und/oder Frässtation zugeführt, daß die bisher nicht bearbeiteten Flächen außen liegen,
  • c. die übereinanderliegenden Platten werden in einem Takt gemeinsam und gleichzeitig an ihren bisher nicht bearbeiteten Flächen und/oder ihren Schmalseiten bearbeitet, und
  • d. die beidseits bearbeiteten Platten werden vereinzelt.
    • If the plate-shaped workpieces are to be processed on both sides, the following method steps are advantageously provided:
  • a. in the case of double-sided surface processing, the plates are again buffered in a magazine so that the previously processed surfaces are alternately up / down,
  • b. two plates lying one above the other are fed to a drilling and / or milling station so that the previously unworked surfaces are on the outside,
  • c. the superimposed plates are processed together in one cycle and simultaneously on their previously unprocessed surfaces and / or their narrow sides, and
  • d. the plates processed on both sides are separated.

    • Damit nach einer vollständigen Bearbeitung alle Werkstücke gleich ausgerichtet sind, ist nach einer besonderen Weiterbildung vorgesehen, daß am Ende der vollständigen Bearbeitung der Platten jede zweite Platte so gewendet wird, daß ihre zuletzt bearbeitete Fläche unten liegt.So that after complete machining, all workpieces are aligned in the same way are, according to a special training that at the end of the complete processing of the plates every second plate is turned so that their last worked area lies below.

    Gemäß einer vorteilhaften Weiterbildung ist weiterhin vorgesehen, daß die Platten gereinigt werden, bevor sie im Magazin zwischengepuffert werden. Durch diese Maßnahme wird ein sicherer Transport der übereinanderliegenden Platten gewährleistet und Ungenauigkeiten bei der Bearbeitung aufgrund von Verschmutzungen vermieden.According to an advantageous development, it is further provided that the plates cleaned before they are buffered in the magazine. Through this This ensures that the stacked panels are transported safely and inaccuracies in processing due to contamination avoided.

    Unter Bezugnahme auf die Figuren wird im folgenden die Erfindung näher erläutert.The invention is explained in more detail below with reference to the figures.

    Hierbei wird zunächst auf FIG. 1 mit den Bezugsziffern 1- 9 Bezug genommen. Die entsprechenden Vorrichtungen werden, soweit dies zum Verständnis des Verfahrens erforderlich erscheint beschrieben, sind aber nicht dargestellt.First, FIG. 1 with the reference numbers 1-9. The Appropriate devices will be used, insofar as this is necessary to understand the procedure required appears described, but is not shown.

    Die zugeführten Platten (1) werden durch eine handelsübliche Reinigungsmaschine gesäubert (je nach Erfordernis Ober- und/oder Unterseite), um negative Einflüsse (z. B. Flächenbeschädigungen oder Bearbeitungsungenauigkeiten) bei den nachfolgenden Verfahrensschritten sicher auszuschließen.The plates (1) are fed through a commercially available cleaning machine cleaned (depending on requirements top and / or bottom) to avoid negative influences (e.g. Surface damage or processing inaccuracies) in the following Exclude procedural steps safely.

    Anschließend werden die Platten auf ein Riemenfördersystem mit aufgebauter Portalbrücke übergeben, an der pendelnd gelagerte, mit Dämpfungsmaterial beschichtete Haken befestigt sind, die ein sicheres und beschädigungsfreies Wenden auch sehr empfindlicher und weicher Materialien ermöglichen (im folgenden als "Pendelwender" bezeichnet).The plates are then transferred to a belt conveyor system with a built-in gantry bridge, on which pendulum-mounted hooks coated with damping material are attached, which enable safe and damage-free turning of even very sensitive and soft materials (hereinafter referred to as " pendulum turner").

    Das System läßt die Funktionen

    • jede Platte wenden
    • nicht wenden
    • jede zweite Platte wenden (2)
    • jede erste Platte wenden
    zu, so daß die gewünschte Lage der Bearbeitungsflächen (3) im nachgeschalteten Magazin in Abhängigkeit von den Vorbedingungen erreicht wird.The system leaves the functions
    • turn each plate
    • do not turn
    • turn every other plate (2)
    • turn every first plate
    to so that the desired position of the processing surfaces (3) in the downstream magazine is achieved depending on the preconditions.

    Die Übergabe in das Magazin erfolgt mit hoher Geschwindigkeit und ist gegen vorzeitiges Abkippen gesichert, so daß eine flache "Flugbahn" entsteht. Zusammen mit der begrenzten, auf die Materialeigenschaften abgestimmte Fallhöhe und den eingebauten Endlagendämpfern zur Aufnahme der kinetischen Energie erfolgt eine beschädigungsfreie Stapelbildung in der gewünschten The transfer into the magazine takes place at high speed and is secured against premature tipping, so that a flat " trajectory" is created. Together with the limited drop height, which is matched to the material properties, and the built-in end position dampers for absorbing the kinetic energy, a damage-free stack formation takes place in the desired one

    Form (3). Im nächsten Verfahrensschritt (4) werden dem Magazin mit Hilfe eines kombinierten Riemen-/Nockenkettensystems zwei Platten gleichzeitig entnommen und der ersten Bohrstation zugeführt. Das Transportsystem besteht aus zwei synchronisierten/kombinierten Riemen-/Nockensystemen (links/rechts), welche in den Bohrautomaten integriert sind. Die Werkstücke (untere Platte) liegen auf dem gegenüber dem Nockensystem geringfügig langsamer laufendem Riemen auf, so daß einerseits für einen formschlüssigen und damit verkantungsfreien, andererseits für einen von "Schleifspuren" freien Transport gesorgt ist. Das System arbeitet im Takt, fördert die beiden übereinanderliegenden Platten zunächst in die Bearbeitungsstation, die Bearbeitung wird ausgeführt, die Platten werden ausgefördert und auf ein in Durchlaufrichtung überlappend angeordnetes, mit dem Riemen-/Nockensystem synchronisiertes, kontinuierlich laufendes Riemenfördersystem weitgehend "kräftefrei" übergeben. Das System gewährleistet den beschädigungsfreien und sicheren Transport im "Doppelpack" auch bei relativ glatten Oberflächen und nicht ebenen Flächen, wie sie im beschriebenen Anwendungsgebiet vorkommen. Von hier werden die Platten gemeinsam einem Fördersystem mit integrierter Vereinzelungsvorrichtung zugeführt, vereinzelt (5) und anschließend mit Hilfe einer handelsüblichen Abblasmaschine rundum gereinigt.Form (3). In the next process step (4), two plates are simultaneously removed from the magazine using a combined belt / cam chain system and fed to the first drilling station. The transport system consists of two synchronized / combined belt / cam systems (left / right), which are integrated in the automatic drills. The workpieces (lower plate) rest on the belt, which runs slightly slower than the cam system, so that, on the one hand, a form-fitting and thus tilt-free, and on the other hand a transport free of " grinding marks" is ensured. The system works in time, initially conveys the two superimposed plates to the processing station, the processing is carried out, the plates are conveyed out and transferred to a continuously running belt conveyor system that is overlapping in the direction of flow and is synchronized with the belt / cam system and is largely " force-free". The system ensures damage-free and safe transport in a "double pack" even with relatively smooth surfaces and non-flat surfaces, such as those that occur in the application area described. From here, the plates are fed together to a conveyor system with an integrated separating device, separated (5) and then cleaned all around using a standard blow-off machine.

    Im nächsten Arbeitsgang (6) erfolgt eine erneute Stapelbildung gemäß Arbeitsgang (3), dann die Komplettierung der Bearbeitung (8) wie in Arbeitsgang (4) beschrieben.In the next step (6), a new stack formation takes place in accordance with Operation (3), then the completion of the processing (8) as in operation (4) described.

    In Abhängigkeit von den Anforderungen werden die Platten gegebenenfalls gewendet (9), wobei die gleichen Funktionsoptionen wie bei Arbeitsgang (2) zur Verfügung stehen.Depending on the requirements, the plates may be turned over (9), with the same functional options as for operation (2) stand.

    Die in FIG. 1 gezeigten und in den Verfahrensschritten (4) und (7) durchzuführenden Bearbeitungen sind beliebig gewählt und dienen nur der Veranschaulichung.The in FIG. 1 shown and to be carried out in process steps (4) and (7) Edits are chosen arbitrarily and are only for illustration.

    Die Aggregatbestückung der Bearbeitungsstationen und damit die möglichen Bearbeitungen sind jeweils auf den Anwendungsfall abzustimmen. Im übrigen läßt sich das Verfahren flexibel auf den jeweiligen Anwendungsfall bezogen gestalten. The assembly of the processing stations and thus the possible Processing must be tailored to the application. For the rest, make the process flexible based on the respective application.

    Sämtliche Transportsysteme sollten mindestens mit manuell regelbaren Vorschubantrieben ausgerüstet sein, um einen auf die jeweiligen Produkte abgestimmten Ablauf sicherzustellen.All transport systems should at least be controlled manually Feed drives must be equipped to match the respective products ensure a coordinated process.

    Mit der Erfindung werden insbesondere folgende Vorteile erzielt:
    Verdoppelung der Mengenleistung gegenüber der konventionellen Verfahrensweise, welches eine Integration der Bohr- und Stationärfräsbearbeitung in Linie mit einer kontinuierlich im Durchlauf arbeitenden Format- und Kantenbearbeitungsanlage sinnvoll möglich macht.    The following advantages are achieved in particular with the invention:
    Doubling of the volume output compared to the conventional procedure, which makes it possible to integrate drilling and stationary milling in line with a continuously working format and edge processing system.

    Hieraus resultieren die bekannten Vorteile, die sich bei der Zusammenfassung von Arbeitsgängen ergeben und von denen einige im folgenden noch einmal aufgeführt sind:

  • Verringerung der Produktionsfläche durch Wegfall der Materialpufferbereiche vor den "Insellösungen" für die Bohr- und Stationärfräsbearbeitung
  • Einsparung von Automatisierungskomponenten für die "Insellösungen"
  • Verringerung des Transportaufwandes innerhalb der Fertigung
  • Verbesserung des Materialflusses und Vereinfachung der Fertigungssteuerung
    • This gives rise to the well-known advantages of combining operations, some of which are listed below:
  • Reduction of the production area by eliminating the material buffer areas in front of the "island solutions" for drilling and stationary milling
  • Saving of automation components for the "isolated solutions"
  • Reduction of transport costs within the production
  • Improve material flow and simplify manufacturing control

    • Ein Ausführungsbeispiel des Verfahrens in Form einer kompletten Fertigungsstraße mit Angabe der notwendigen Vorrichtungen/Anlagen-komponenten zeigt FIG. 2. Die dargestellte Fertigungsstraße erlaubt die Serienproduktion von furnierten Möbelteilen mit Rundum-Bekantung der Schmalflächen. Die Plattenlängen variieren zwischen 400 mm und 1200 mm, die Plattenbreiten zwischen 300 mm und 600 mm.An embodiment of the method in the form of a complete production line with The specification of the necessary devices / system components is shown in FIG. 2. The The production line shown allows the serial production of veneered furniture parts with all-round edging of the narrow surfaces. The plate lengths vary between 400 mm and 1200 mm, the plate widths between 300 mm and 600 mm.

    Die fumierten "Rohplatten" werden der automatischen Beschickungsanlage (1) im Stapel (mindestens 3 Stapel hintereinander je Seite, mehr sind in Abhängigkeit von der Plattenlänge möglich) zugeführt. Die Anlage ist doppelseitig ausgeführt, so daß eine kontinuierliche Arbeitsweise ohne Stapelwechselzeiten sichergestellt wird. Es werden je Takt mindestens 3 Platten mittels Vakuum aufgenommen und der Format- und Kantenbearbeitungsanlage (2) für die "Längsbearbeitung" zugeführt. Hier werden die Platten formatiert, an die Schmalflächen Furnierkanten angeleimt, komplett nachbearbeitet und je nach Produkt gegebenenfalls weitere Bearbeitungen durchgeführt. Anschließend wird mit der Kegeldrehstation (3) von "längs" auf "quer" gedreht und an die Format- und Kantenbearbeitungsanlage (4) übergeben. Hier erfolgt die Quer-Bearbeitung (Bearbeitungen wie auf Anlage 2, produktabhängig).The fumed " raw panels" are fed to the automatic loading system (1) in a stack (at least 3 stacks in a row on each side, more are possible depending on the panel length). The system is double-sided, so that continuous operation without batch change times is ensured. At least 3 plates per cycle are picked up by vacuum and fed to the format and edge processing system (2) for "longitudinal processing". Here the panels are formatted, glued to the narrow surfaces of the veneer edges, completely reworked and, depending on the product, further processing may be carried out. The cone turning station (3) is then used to turn from " longitudinal" to " transverse" and is transferred to the format and edge processing system (4). The cross-processing takes place here (processing as in Appendix 2, depending on the product).

    Im Anschluß werden die Platten von dem Pendelwender (5) mit einlaufseitig aufgebauter Werkstückreinigung (Oberseite) übernommen (Arbeitsgang 2 gemäß FIG. 1) und schließlich dem Bohr- und Fräsautomat (6) zugeführt (Arbeitsgänge 3/4 gemäß FIG. 1). Anschließend erfolgt auf dem Gurtförderer mit Vereinzelungsvorrichtung (7) die Vereinzelung (Arbeitsgang 5 gemäß FIG. 1), dann die beidseitige Werkstückreinigung mittels einer handelsüblichen Reinigungsanlage (8), danach im Bohrautomat (9) die Komplettierung der Bohr- und Stationärfräsbearbeitung (Arbeitsgang 6/7 gemäß FIG. 1), schließlich erfolgt auf dem Gurtförderer mit integrierter Vereinzelungsvorrichtung (10) die Plattenvereinzelung mit folgender beidseitiger Werkstückreinigung durch die Reinigungsanlage (11). Danach erfolgt die Übergabe auf den Pendelwender (12), wo so gewendet wird, daß die bearbeiteten Plattenflächen unten liegen (Arbeitsgang 8/9 gemäß FIG. 1).The plates are then connected to the pendulum turner (5) on the inlet side Assembled workpiece cleaning (top) taken over (operation 2 according to FIG. 1) and finally fed to the automatic drilling and milling machine (6) (operations 3/4 according to FIG. 1). This is followed by a separation device on the belt conveyor (7) the separation (operation 5 according to FIG. 1), then the two-sided Workpiece cleaning using a commercially available cleaning system (8), then in Automatic drilling machine (9) completing drilling and stationary milling (Operation 6/7 according to FIG. 1), finally takes place on the belt conveyor with integrated Separating device (10) the plate separation with the following on both sides Workpiece cleaning by the cleaning system (11). Then the handover takes place on the pendulum turner (12), where it is turned so that the machined plate surfaces lie below (operation 8/9 according to FIG. 1).

    Es folgt das Drehen von "quer" auf "längs" in der Drehstation (13) und die anschließende kantengenaue Stapelbildung (Einzelplattenstapel) in der ebenfalls doppelseitigen Stapelanlage (14). Die Plattenstapel werden von hieraus direkt zur Oberflächenbehandlung verbracht, wo zunächst die Kanten im Stapel lackiert werden.It follows the turning from "transverse" to "longitudinal" in the turning station (13) and the subsequent edge-precise stack formation (single plate stack) in the likewise double-sided stacking system (14). From here, the plate stacks become directly Surface treatment spent where the edges are first painted in the stack.

    Die Gesamtanlage ist mit einer übergeordneten produktbezogenen Vorschubsteuerung ausgerüstet, welche den einwandfreien Ablauf sicherstellt.The entire system has a higher-level product-related feed control equipped, which ensures the perfect process.
