Description

Die Erfindung betrifft eine Kantenanleimmaschine zur Anleimung einer Kante auf ein zwischen einem in der Höhe verstellbaren Rollenoberdruck und einer Fördereinrichtung entlang eines Anschlags geführtes Werkstück, mit wenigstens einem Bearbeitungsaggregat für die Längsbearbeitung der aufgeleimten Kante.The invention relates to an edge banding machine for gluing an edge onto a workpiece guided between a height-adjustable roller top pressure and a conveyor along a stop, with at least one processing unit for the longitudinal processing of the glued edge.

Kantenanleimmaschinen werden zum Anleimen von Kantenmaterial aus Holz oder holzähnlichen Werkstoffen auf Platten aus Holz oder holzähnlichen Werkstoffen verwendet. Die Platten werden dabei mit kontinuierlicher Geschwindigkeit durch die Maschine bewegt und das Kantenmaterial von einer Rolle bzw. in vorabgelängten Streifen bzw. Leisten zugeführt und mit der Platte dauerhaft verbunden. Die angeleimten Kanten werden anschließend in Längsrichtung durch verschiedene hintereinander angeordnete Bearbeitungsaggregate je nach Aufgabenstellung bearbeitet. Solche Bearbeitungsaggregate sind u.a. Bündigfräsaggregate oder Feinfräsaggregate.Edge banding machines are used for gluing edge material made of wood or wood-like materials onto boards made of wood or wood-like materials. The panels are moved through the machine at a constant speed and the edging material is fed from a roll or in pre-cut strips or strips and permanently connected to the panel. The glued edges are then processed in the longitudinal direction by various processing units arranged one behind the other depending on the task. Such processing units include Flush trimming units or fine trimming units.

Es sind Kantenanleimmaschinen, beispielsweise die Kantenanleimmaschine "Kantomat" der Firma Paul Ott GmbH, bekannt, bei denen die Bearbeitungsaggregate auf einem horizontal angeordneten Maschinengrundkörper hintereinander angeordnet sind. Die Bearbeitungsaggregate sind auf einer ebenen, bearbeiteten horizontale Fläche verschraubt. Je nach Aufgabenstellung müssen die Werkzeuge der Aggregate in vertikaler bzw in vertikaler und horizontaler Richtung beweglich sein, um sich an die Bearbeitungskante des Werkstücks anpassen zu können.Edge banding machines, for example the "Kantomat" edge banding machine from Paul Ott GmbH, are known in which the processing units are arranged one behind the other on a horizontally arranged machine base. The processing units are screwed onto a flat, machined horizontal surface. Depending on the task, the tools of the aggregates must be vertical or be movable in the vertical and horizontal directions in order to be able to adapt to the machining edge of the workpiece.

Bündigfräsaggregate dienen zum Vorfräsen der aufgeleimten Kante und sorgen für einen bündigen Übergang vom Werkstück zur Kante. Sie müssen daher in vertikaler Richtung, d.h. normal zum Werkstück, zugestellt werden. Eine mit dem Bündigfräsaggregat verbundene Tastrolle drückt mit einer gewissen Vorspannkraft auf das Werkstück, damit der Messerkopf des Bündigfräsaggregats einen konstanten Abstand zur Oberfläche des Werkstücks hat. Bei den bekannten Kantenanleimmaschinen wird das Bündigfräsaggregat vertikal in einer Linearführung geführt und manuell zugestellt.Flush milling units serve to pre-mill the glued edge and ensure a flush transition from the workpiece to the edge. You must therefore in the vertical direction, i.e. normal to the workpiece. A feeler roller connected to the flush milling unit presses the workpiece with a certain preload force so that the cutter head of the flush milling unit is at a constant distance from the surface of the workpiece. In the known edge banding machines, the flush trimming unit is guided vertically in a linear guide and fed manually.

Feinfräsaggregate dienen zum Fertigfräsen aufgeleimter und in der Regel vorgefräster Kanten, wobei die Bearbeitung im wesentlichen in der Herstellung von Fasen mit unterschiedlichen Fasenstärken und Fasenwinkeln sowie von Radien besteht. Die Feinfräsaggregate sind bei den bekannten Kantenanleimmaschinen sowohl horizontal als auch vertikal in Linearführungen geführt.Fine milling units are used for finish milling glued and generally pre-milled edges, the processing essentially consisting in the production of chamfers with different chamfer thicknesses and chamfer angles as well as radii. In the known edge banding machines, the fine milling units are guided both horizontally and vertically in linear guides.

Durch die erforderlichen Linearführungen sind die bekannten Kantenanleimmaschinen konstruktiv sehr aufwendig und verursachen daher auch hohe Kosten.Due to the required linear guides, the known edge banding machines are structurally very complex and therefore also cause high costs.

Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln eine Kantenanleimmaschine zu schaffen, deren Bearbeitungsaggregate für die Längsbearbeitung der aufgeleimten Kante mit geringem Aufwand in vertikaler Richtung zu- und rückstellbar sind und diese Bewegung mit z.B. Pneumatikzylindern leicht berwerkstelligbar und automatisierbar ist.The invention has for its object to provide an edge banding machine with structurally simple means, the processing units for the longitudinal processing of the glued edge can be adjusted and reset with little effort in the vertical direction and this movement can be easily accomplished and automated with, for example, pneumatic cylinders.

Diese Aufgabe wird ausgehend von dem gattungsgemäßen Stand der Technik dadurch gelöst, daß das Bearbeitungsaggregat auf einer zur Führungsrichtung des Werkstücks parallelen Achse schwenkbar angeordnet ist. Die Achse dient gleichzeitig als Aufnahme und Befestigung der Aggregate.Starting from the generic state of the art, this object is achieved in that the machining unit is pivotably arranged on an axis parallel to the guide direction of the workpiece. The axis also serves as the mounting and attachment of the units.

Diese erfindungsgemäße Ausgestaltung der Kantenanleimmaschine ermöglicht es, daß die Bearbeitungsaggregate lediglich durch Verschwenkung auf der Achse vertikal zugestellt werden müssen. Die erfindungsgemäße Kantenanleimmaschine ist daher konstruktiv sehr einfach. Darüberhinaus können die Bearbeitungsaggregate von einem Bediener schnell auf die entsprechende Werkstückstärke eingestellt werden. Es hat sich dabei überraschenderweise gezeigt, daß der Winkelversatz, der kleiner als ein Grad ist, vernachlässigt werden kann. Die erfindungsgemäße Kantenanleimmaschine ist daher insbesondere für Kantenanleimmaschinen geeignet, die für eine geringe Kantenstärke konzipiert sind.This configuration of the edge banding machine according to the invention enables the processing units to be fed vertically only by pivoting on the axis. The edge banding machine according to the invention is therefore structurally very simple. In addition, the processing units can be quickly set to the appropriate workpiece thickness by an operator. It has surprisingly been found that the angular misalignment, which is less than one degree, can be neglected. The edge banding machine according to the invention is therefore particularly suitable for edge banding machines which are designed for a low edge thickness.

Dabei werden die Bearbeitungsaggregate zur Berarbeitung der oberen Längsseite auf einer zum verstellbaren Rollenoberdruck parallel angeordneten und an diesem befestigten oberen Achse angeordnet.The processing units for processing the upper longitudinal side are arranged on an upper axis arranged parallel to the adjustable roller top pressure and fastened to it.

Bearbeitungsaggregate zur Bearbeitung der unteren Längs-seite werden an einer parallel zum Rahmen, an dem die Fördereinrichtung aufgenommem ist, angeordneten unteren Achse schwenkbar befestigt.Processing units for processing the lower longitudinal side are pivotally attached to a lower axis arranged parallel to the frame on which the conveying device is accommodated.

Zu- und rückstellbare Bearbeitungsaggregate werden dabei über Pneumatikzylinder abgestützt und mit diesen auch vor- und rückgestellt. Der erforderliche Anpreßdruck wird in der zugestellten Position ebenfalls durch diese Pneumatikzylinder bewerkstelligt.Machining units that can be moved in and out are supported by pneumatic cylinders and are also used to advance and reset them. The required contact pressure is also achieved in this position by these pneumatic cylinders.

Fig.1 zeigt einzelne Arbeitsbereiche der Kantenanleimmaschine. Am Einlauf der Maschine wird das Werkstück, beispielsweise eine Platte 10 entlang eines Anschlags 12 in einer Führungsrichtung F eingeführt. In Führungsrichtung nach dem Anschlag 12 befindet sich die Druckzone D, in der eine Kante 14 auf eine Stirnseite der Platte 10 geleimt wird. Die Kante 14 wird von einer nicht gezeigten Rolle zugeführt und über eine erste angetriebene Druckrolle 16 umgelenkt. Anschließend an die Druckrolle 16 sind mehrere Preßrollen 18 angeordnet, die zur Anpressung der Kante 14 an die Platte 10 dienen.Fig. 1 shows individual work areas of the edge banding machine. At the inlet of the machine, the workpiece, for example a plate 10, is introduced along a stop 12 in a guide direction F. In the guiding direction after the stop 12 is the pressure zone D, in which an edge 14 is glued to an end face of the plate 10. The edge 14 is from a roll, not shown fed and deflected via a first driven pressure roller 16. Subsequent to the pressure roller 16, a plurality of pressure rollers 18 are arranged, which serve to press the edge 14 onto the plate 10.

Anschließend an die Druckzone D ist in Führungsrrichtung der Platte 10 eine Bearbeitungszone B vorgesehen, in der mehrere, in Fig. 1 nicht gezeigte Bearbeitungsaggregate die aufgeleimte Kante 14 bearbeiten. Bearbeitungsaggregate für die Längsbearbeitung der Kante sind zum Beispiel Bündigfräsaggregate, Radius- und Fasefräsaggregate (Feinfräsaggregate), Ziehklingenaggregate oder Kantenputzaggregate. Darüberhinaus kann auch ein Kappaggregat angebracht sein, daß die Kante in Querrichtung ablängt.Following the printing zone D, a processing zone B is provided in the guide direction of the plate 10, in which a plurality of processing units (not shown in FIG. 1) process the glued edge 14. Processing units for the longitudinal processing of the edge are, for example, flush milling units, radius and chamfer milling units (fine milling units), scraper blade units or edge cleaning units. In addition, a trimming unit can also be attached so that the edge is cut to length in the transverse direction.

Wie es durch die Pfeile A in Fig.1 angedeutet ist, ist der Anschlag 12 quer zur Führungsrichtung F einstellbar. Der Anschlag 12 wird so eingestellt, daß seine Anschlagfläche in einer Ebene mit der Anleimfläche der Kante 14 in der Druckzone B liegt. Die Bearbeitungskante 20 in der Bearbeitungszone ist fest eingestellt. Sie liegt in einer Ebene mit den Andruckpunkten der Preßrollen 18.As indicated by the arrows A in FIG. 1, the stop 12 can be adjusted transversely to the guide direction F. The stop 12 is set so that its stop surface lies in a plane with the gluing surface of the edge 14 in the pressure zone B. The processing edge 20 in the processing zone is fixed. It lies in one plane with the pressure points of the pressure rollers 18.

Wie es in Fig.2 gezeigt ist, weist die Kantenanleimmaschine einen als Formrohr ausgebildeten Rollenträger 24 eines Rollenoberdrucks 22 (Fig. 3) auf, der, wie es durch die Pfeile angedeutet ist, in vertikaler Richtung einstellbar ist. Hierdurch kann der Rollenoberdruck 22 entsprechend der Dicke der Platte 10 eingestellt werden.As shown in FIG. 2, the edge banding machine has a roller carrier 24 of a roller top pressure 22 (FIG. 3) designed as a shaped tube, which, as indicated by the arrows, can be adjusted in the vertical direction. As a result, the upper roller pressure 22 can be set in accordance with the thickness of the plate 10.

An der Seitenfläche des Rollenträgers 24 sind sich horizontal erstreckende obere Querträger 34 normal zu dem Rollenträger 24 angebracht. An den oberen Querträgern 34 ist eine obere Achse 36 so gelagert, daß sie parallel zum Rollenträger 24 und parallel zur Führungsrichtung F (Fig.1) des Werkstücks 10 in einer horizontalen Ebene verläuft.On the side surface of the roller carrier 24, horizontally extending upper cross members 34 are attached normal to the roller carrier 24. On the upper cross members 34, an upper axis 36 is mounted so that it is parallel to the roller carrier 24 and parallel to the guide direction F (Fig.1) Workpiece 10 extends in a horizontal plane.

Unterhalb des Rollenträgers 24 ist ein Rahmen 32 vorgesehen, der eine Fördereinrichtung trägt, die von einem Kettenantrieb 28 (Fig.3) gebildet wird. An dem Rahmen 32 sind ebenfalls untere Querträger 38 normal zum Rahmen 32 angebracht. Die unteren Querträger 38 tragen eine untere Achse 40, die parallel zur oberen Achse 36 und zur Führungsrichtung F verläuft.Below the roller carrier 24, a frame 32 is provided which carries a conveyor device which is formed by a chain drive 28 (FIG. 3). Lower cross members 38 are also attached to the frame 32 normally to the frame 32. The lower cross members 38 carry a lower axis 40 which runs parallel to the upper axis 36 and to the guide direction F.

Wie es in den Fig. 3 und 7 gezeigt ist, sind an der Unterseite des Rollenträgers 24 Druckrollen 22 angebracht, die einen Druck auf die Oberfläche der eingeführten Platte 10 ausüben. Die Platte 10 liegt auf den Kettenplatten 30 des oberen Trums des Kettenantriebes 28 auf, der auf dem Rahmen 32 angebracht ist. Die Platte 10 wird durch die Kette 28 gefördert.As shown in FIGS. 3 and 7, pressure rollers 22 are attached to the underside of the roller carrier 24 and exert pressure on the surface of the inserted plate 10. The plate 10 lies on the chain plates 30 of the upper run of the chain drive 28, which is attached to the frame 32. The plate 10 is conveyed by the chain 28.

Wie es in Fig. 3 gezeigt ist, weist ein sich senkrecht von dem Rollenträger 24 erstreckender obere Querträger 34 zur Lagerung eines oberen Bündigfräsaggregats 48 an seinem dem Rollenträger 24 abgewandten Ende einen sich nach unten erstreckenden Abschnitt auf, in dem die obere Achse 36 befestigt ist. Auf der Achse 36 ist das Bündigfräsaggregat 48 angelenkt. Hierzu weist das Bündigfräsaggregat 48 einen Lagerklotz 35 auf. An dem Lagerklotz 35 ist eine Schwenkplatte 49 senkrecht zur Achse 36 befestigt. Auf der Schwenkplatte 49 ist der Antriebsmotor 62 des Bündigfräsaggregates 48 befestigt, an dessen der oberen Achse 36 abgewandten Ende ein Messerkopf 52 zur Bearbeitung der Kante 14 angeordnet ist.As shown in FIG. 3, an upper cross member 34, which extends perpendicularly from the roller carrier 24, for supporting an upper flush milling unit 48 has a downwardly extending section at its end facing away from the roller carrier 24, in which section the upper axis 36 is fastened . The flush milling unit 48 is articulated on the axis 36. For this purpose, the flush milling unit 48 has a bearing block 35. A pivot plate 49 is fastened to the bearing block 35 perpendicular to the axis 36. The drive motor 62 of the flush milling unit 48 is fastened on the swivel plate 49, on the end of which facing away from the upper axis 36 a cutter head 52 for processing the edge 14 is arranged.

Die Höhe der Achse 36 ist so gewählt, daß die Schneiden des Messerkopfes 52 in der in Fig. 3 gezeigten Bearbeitungsstellung parallel zur Oberfläche der Platte 10 verlaufen.The height of the axis 36 is selected so that the cutting edges of the cutter head 52 in the processing position shown in FIG. 3 run parallel to the surface of the plate 10.

Das Bündigfräsaggregat 48 besitzt eine Tastrolle 60, die in bekannter Weise den Messerkopf 52 des Bündigfräsaggregats 48 so steuert, daß der Übergang von Platte 10 zur Kante bündig bleibt.The flush milling unit 48 has a feeler roller 60 which controls the cutter head 52 of the flush milling unit 48 in a known manner so that the transition from plate 10 to the edge remains flush.

An der Schwenkplatte 49 ist im Bereich des Messerkopfes 52 eine Kolbenstange 58 eines Pneumatikzylinders 56 angelenkt. Der Pneumatikzylinder 56 ist an seinem der Kolbenstange 58 gegenüberliegenden Ende an einem an dem Rahmen 24 befestigten Winkel 54 angelenkt.A piston rod 58 of a pneumatic cylinder 56 is articulated on the swivel plate 49 in the area of the cutter head 52. The pneumatic cylinder 56 is articulated at its end opposite the piston rod 58 to an angle 54 fastened to the frame 24.

Der an dem Rahmen 32 angebrachte untere Querträger 38 weist an seinem dem Rahmen 32 gegenüberliegenden Ende einen sich nach oben erstreckenden Abschnitt 41 auf, in dem die untere Achse 40 befestigt ist. An der Achse 40 ist ebenfalls ein Bündigfräsaggregat 50 schwenkbar gelagert. Die Höhe der Achse 40 ist so gewählt, daß der Messerkopf 52 des Bündigfräsaggregats 50 in der in Fig.3 gezeigten Bearbeitungsstellung parallel zur Unterseite der Platte 10 verläuft. Das Bündigfräsaggregat 50 ist in gleicher Weise mit einem Pneumatikzylinder 56 verbunden, wie das obere Bündigfräsaggregat 48. Zur Anpassung an die Kontur der Unterseite der Plate 10 hat das untere Bündigfräsaggregat ebenfalls eine Tastrolle 60. Der Pneumatikzylinder 56 ist an seinem dem Kolben 58 gegenüberliegenden Ende an einer sich senkrecht vom Rahmen 32 erstreckenden Querstrebe 54 angelenkt. Zur Anpassung an die Kontur der Unterseite der Platte 10 ist das untere Bündigfräsaggregat 50 ebenfalls mit einer Tastrolle 60 verbunden.The lower cross member 38 attached to the frame 32 has at its end opposite the frame 32 an upwardly extending section 41 in which the lower axis 40 is fastened. A flush milling unit 50 is also pivotably mounted on the axis 40. The height of the axis 40 is selected so that the cutter head 52 of the flush milling unit 50 in the machining position shown in FIG. 3 runs parallel to the underside of the plate 10. The flush milling unit 50 is connected to a pneumatic cylinder 56 in the same way as the upper flush milling unit 48. To adapt to the contour of the underside of the plate 10, the lower flush milling unit also has a feeler roller 60. The pneumatic cylinder 56 is at its end opposite the piston 58 a cross strut 54 extending perpendicularly from the frame 32. In order to adapt to the contour of the underside of the plate 10, the lower flush milling unit 50 is also connected to a feeler roller 60.

Die Kolbenstange 58 ist in der Bearbeitungsstellung des Bündigfräsaggregats 48 voll ausgefahren. Wie es in Fig. 6 gezeigt ist, befindet sich der Messerkopf 52 und die Tastrolle 60 des oberen Bündigfräsaggregats 48 in diesem ausgefahrenen Zustand um den Abstand a unterhalb der gedachten Ebene der oberen Oberfläche einer Platte 10, wenn keine Platte 10 zwischen die Bündigfräsaggregate 48, 50 eingeführt ist. In gleichem Maße befindet sich der Messerkopf 52 und die Tastrolle 60 des unteren Bündigfräsaggregats 50 im ausgefahrenen Zustand um den Abstand a oberhalb der gedachten Ebene der unteren Oberfläche einer Platte 10. Die Vorspannung a beträgt vorzugsweise 1 mm.The piston rod 58 is fully extended in the processing position of the flush milling unit 48. As shown in FIG. 6, the cutter head 52 and the feeler roller 60 of the upper flush milling unit 48 are in this extended state by the distance a below the imaginary one Level of the upper surface of a plate 10 when no plate 10 is inserted between the flush milling units 48, 50. To the same extent, the cutter head 52 and the feeler roller 60 of the lower flush milling unit 50 are in the extended state by the distance a above the imaginary plane of the lower surface of a plate 10. The pretension a is preferably 1 mm.

Der Abstand des Messerkopf 52 von der Achse 36 bzw. 40 beträgt dagegen ca. 300 mm. Daraus folgt, daß der entstehende Winkelversatz bei der Abtastung sehr gering und daher im Einsatz vernachlässigbar ist.The distance of the cutter head 52 from the axis 36 or 40, however, is approximately 300 mm. It follows that the resulting angular misalignment when scanning is very small and therefore negligible in use.

Das in den Fig. 7 und 8 gezeigte Feinfräsaggregat ist auf der oberen Achse 36 schwenkbar gelagert. Für die schwenkbare Lagerung ist ein Lagerklotz 70 vorgesehen, durch den die Achse 36 hindurchgeht. Oberhalb der Achse 36 ist in dem Lagerklotz 70 eine im wesentlichen horizontale Bohrung 73 vorgesehen, die im rechten Winkel zur Achse 36 verläuft. In der Bohrung 73 ist eine Führungsstange 74 im wesentlichen horizontal verschiebbar gelagert, an deren dem Rollenträger 24 zugewandten Stirnende eine vertikale Schwenkplatte 72 befestigt ist. Auf der Oberfläche der Schwenkplatte 72 ist ein Motor 80 mit Werkzeug 52 um eine zur Achse 36 parallele Schwenkachse verschwenkbar angebracht. Die Schwenkposition des Motors 80 auf der Schwenkplatte 72 ist in z.B. 15°-Schritten einstellbar. Auf der Schwenkplatte 72 ist außerdem ein Tastklotz 86 im wesentlichen horizontal verschiebbar gelagert. Wie es in Fig. 7 gezeigt ist, liegt der Tastklotz 86 während der Bearbeitung auf der aufgeleimten Kante 14 des Werkstücks 10 auf. Der Tastklotz 86 ist an einer Winkelplatte 82 befestigt, die auf der Schwenkplatte über ein Langloch verstellbar mit einer Schraube befestigt ist. Durch die Verschiebbarkeit des Tastklotzes 86 relativ zum Werkzeug 52 können unterschiedliche Bearbeitungen, z.B. Fasen, bewerkstelligt werden.The fine milling unit shown in FIGS. 7 and 8 is pivotally mounted on the upper axis 36. A bearing block 70 through which the axis 36 passes is provided for the pivotable mounting. Above the axis 36, an essentially horizontal bore 73 is provided in the bearing block 70 and extends at a right angle to the axis 36. In the bore 73, a guide rod 74 is mounted so as to be substantially horizontally displaceable, to the end of which faces the roller carrier 24, a vertical swivel plate 72 is fastened. A motor 80 with tool 52 is mounted on the surface of the swivel plate 72 so that it can swivel about a swivel axis parallel to the axis 36. The swivel position of the motor 80 on the swivel plate 72 can be set in, for example, 15 ° steps. On the swivel plate 72, a feeler block 86 is also substantially horizontally displaceable. As shown in FIG. 7, the feeler block 86 rests on the glued edge 14 of the workpiece 10 during processing. The feeler block 86 is fastened to an angle plate 82, which is adjustably fastened on the swivel plate by means of a slot with a screw. Due to the displaceability of the feeler block 86 relative to the tool 52, different machining operations, for example Chamfering can be accomplished.

An der Oberseite des Lagerklotzes 70 ist ein Ende eines horizontalen Pneumatikzylinders 76 angebracht, dessen Kolbenstange während der Bearbeitung der Kante 14 gegen die Schwenkplatte 72 drückt. Der Pneumatikzylinder 76 sorgt für den nötigen Anpreßdruck des Tastklotzes 86 in horizontaler Richtung.At the top of the bearing block 70, one end of a horizontal pneumatic cylinder 76 is attached, the piston rod of which presses against the swivel plate 72 during the processing of the edge 14. The pneumatic cylinder 76 provides the necessary contact pressure for the feeler block 86 in the horizontal direction.

An der Schwenkplatte 72 ist oberhalb des Messerkopfes 52 eine Kolbenstange eines vertikale angeordneten Pneumatikzylinders 56 befestigt, dessen Ende wie bei dem in Fig. 3 gezeigten Bündigfräsaggregat am Rahmen 24 angelenkt ist. An der Schwenkplatte 72 ist außerdem eine Tastrolle 60 befestigt, die das Feinfräsaggregat in vertikaler Richtung gegen den Anpreßdruck des Pneumatikzylinders 56 in Bearbeitungsposition führt.On the swivel plate 72, a piston rod of a vertically arranged pneumatic cylinder 56 is fastened above the cutter head 52, the end of which is articulated to the frame 24 as in the flush milling unit shown in FIG. 3. Also attached to the swivel plate 72 is a feeler roller 60, which guides the fine milling unit in the vertical direction against the contact pressure of the pneumatic cylinder 56 in the machining position.

Die Kante kann außerdem noch durch Ziehklingenaggregate oder Kantenputzaggregate bearbeitet werden. Vor dem Bündigfräsaggregat kann auch ein Kappaggregat angeordnet sein. Die Höhe der Achse der jeweiligen Bearbeitungsaggregate ist so gewählt, daß sich ihre Werkzeuge im Einsatz in der gewünschten Bearbeitungslage befinden.The edge can also be processed by scraper units or edge cleaning units. A trimming unit can also be arranged in front of the trimming unit. The height of the axis of the respective processing units is selected so that their tools are in the desired processing position in use.

Nach dem Durchlauf der Bearbeitungszone wird die Platte 10 mit der angeleimten und bearbeiteten Kante 14 aus der Kantenanleimmaschine herausbefördert.After passing through the processing zone, the plate 10 with the glued and processed edge 14 is conveyed out of the edge banding machine.
