Abstract

A device for machining, in particular, profiling tree trunks is provided, which includes two rotating machining tools (2, 3), whose axes (A, B) are essentially offset by 90° in relation to one another and are oriented in an essentially perpendicular direction to the longitudinal axis of the tree trunk. The first machining tool (2) and the second machining tool (3) are arranged in relation to one another in such a way that the first axis (A) and the second axis (B) lie on a common plane (E) and/or that their respective workpiece machining zones (I, II) at least partially overlap one another in the transversal direction of the tree trunk or adjoin one another.

Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Bearbeiten, nämlich zum Profilieren von Baumstämmen mit einem ersten rotierenden Bearbeitungswerkzeug, das um eine erste Achse umläuft und einen ersten Werkstückbearbeitungsbereich aufweist, und mit einem zweiten rotierenden Bearbeitungswerkzeug, das um eine zweite Achse umläuft und einen zweiten Bearbeitungsbereich aufweist, wobei die erste Achse und die zweite Achse im Wesentlichen um 90° versetzt zueinander und im Wesentlichen senkrecht zur Baumstammachse orientiert sind.The invention relates to an apparatus and a method for processing, namely for profiling tree trunks with a first rotating machining tool, which rotates about a first axis and has a first workpiece machining area, and with a second rotating machining tool, which rotates about a second axis and a second Processing region, wherein the first axis and the second axis are substantially offset by 90 ° to each other and oriented substantially perpendicular to the tree trunk axis.

Das Ziel bei diesem Bearbeiten von Baumstämmen besteht darin, einen rechtwinkligen waldkantigen Eckbereich aus dem Baumstamm herauszuarbeiten, um hierbei rechtwinklige Seitenkanten für in einem späteren Bearbeitungsschritt abzutrennende Seitenbretter herzustellen. Bei diesem Herausarbeiten finden einerseits Sägeblätter Anwendung, um mit Hilfe des Sägeschnitts eine optimale Seitenkante des Seitenbrettes herzustellen, und zum anderen Hackmesser, um beim Herausarbeiten des Eckenbereichs des Baumstamms Hackschnitzel mit einer definierten Form herzustellen, die als Nebenprodukt des Baumstammes weiterverkauft werden können.The aim of this processing of tree trunks is to work out a right-angled forest-edged corner area out of the tree trunk in order to produce rectangular side edges for side boards to be cut off in a later processing step. Sawblades are used on this one hand to produce an optimum side edge of the side board with the aid of the saw cut, and on the other hand to produce wood chips with a defined shape when working out the corner region of the tree trunk, which can be resold as a by-product of the tree trunk.

Der einschlägige Stand der Technik beschäftigt sich schon seit Jahrzehnten mit der Technologie des Profilierens. So ist beispielsweise in der DE-A 37 02 890 eine solche Vorrichtung zum Profilieren von Baumstämmen beschrieben, bei der beide rotierende Bearbeitungswerkzeuge aus kombinierten Werkzeugköpfen bestehen, die einerseits Sägeblattelemente und andererseits Hackmesser tragen.The relevant prior art has been dealing for decades with the technology of profiling. For example, in the DE-A 37 02 890 describes such a device for profiling of tree trunks, in which both rotary machining tools consist of combined tool heads, on the one hand carry saw blade elements and on the other hand cleaver.

Eine nahezu identische Profiliervorrichtung ist aus der DE-A 199 60 319 bekannt, bei der jedoch das erste rotierende Bearbeitungswerkzeug keine zusätzlichen Hackmesser aufweist, sondern nur ein Kreissägeblatt umfasst. Hierdurch ist das von den Hackmessern des zweiten Bearbeitungswerkzeuges bearbeitete Zerspanvolumen geringfügig größer als bei der zuvor genannten Vorrichtung mit zwei rotierenden Hackmessern. Der Nachteil eines nur aus einem Kreissägeblatt bestehenden ersten Bearbeitungswerkzeug liegt jedoch darin, dass der von dem Kreissägeblatt gebildete Spalt eine Instabilität in den Bearbeitungsbereich für das zweite Bearbeitungswerkzeug einbringt, da der von dem zweiten Bearbeitungswerkzeug auszuspanende Eckenbereich nur noch einseitig mit dem Baumstamm verbunden ist, während die zweite Seite des Eckenbereichs vollständig durch den Sägeschnitt vom Baumstamm getrennt ist. Beim Beaufschlagen dieses nur einseitig abgestützten Eckenbereichs mittels der Hackmesser des zweiten Bearbeitungswerkzeugs neigt der Eckenbereich aufgrund fehlender Abstützung zum Schwingen, das das Bearbeiten dieses Eckenbereichs durch das zweite Bearbeitungswerkzeug erschwert und das Arbeitsergebnis deutlich beeinträchtigt.A nearly identical profiling is from the DE-A 199 60 319 However, in which the first rotating machining tool has no additional chopping knives, but only a circular saw blade comprises. As a result, the machining volume machined by the chopping knives of the second machining tool is slightly larger than in the case of the aforementioned device with two rotating chopping knives. However, the disadvantage of a first machining tool consisting only of a circular saw blade lies in the fact that the gap formed by the circular saw blade instability in the machining area for the second machining tool because the corner area to be cut out by the second machining tool is only connected on one side to the tree trunk, while the second side of the corner area is completely separated from the tree trunk by the saw cut. When applying this only one-sided supported corner area by means of the chisel of the second processing tool tends the corner area due to lack of support to vibrate, which complicates the editing of this corner area by the second processing tool and significantly affects the work result.

Um dieses federzungenähnliche Schwingen zu verhindern, behilft man sich beim Gegenstand der DE 199 60 319 damit, diesen Spalt im gerade freigesägten, aber vom Hackmesser des zweiten Bearbeitungswerkzeugs noch nicht beaufschlagten Bereich mit Hilfe eines Spaltkeils abzustützen, der ortsfest an der Bearbeitungsvorrichtung zwischen den beiden rotierenden Bearbeitungswerkzeugen positioniert ist. Der Nachteil solcher Spaltkeile besteht darin, dass diese aufgrund ihrer der Sägeschnittbreite entsprechenden Dicke leicht verklemmen können und hierbei den gesamten Produktionsablauf stören. Werden die Spaltkeile in Folge des Verklemmens auch noch beschädigt bzw. dadurch dass sie schnell verschleißen, müssen die Spaltkeile auch noch ausgewechselt werden, was zusätzliche Kosten verursacht. Will man das Auswechseln der Spaltkeile in Folge Verschleiß etwas hinauszögern, so erkauft man sich dies mit so genannten Endlosstreifen, die dadurch entstehen, dass der vom Hackmesser des zweiten Bearbeitungswerkzeugs herauszuspanende Eckenbereich keine ausreichende Abstützung mehr erfährt und hierdurch der Eckenbereich in geringem Maße nach unten so ausweichen kann, dass die Hackmesser nicht das vollständige Volumen des herauszuspanenden Eckenbereichs entfernen können.To prevent this spring-like swinging, you get at the subject of the DE 199 60 319 in order to support this gap in the region which has just been cut, but not yet acted upon by the chopping blade of the second machining tool, by means of a splitting wedge, which is stationarily positioned on the machining device between the two rotating machining tools. The disadvantage of such splitting wedges is that they can easily jam due to their thickness corresponding to the saw cut width and thereby disturb the entire production process. If the splitting wedges also become damaged as a result of jamming or because they wear out quickly, the splitting wedges also have to be replaced, which entails additional costs. If you want to delay the replacement of the splitting wedges as a result of wear something, so you buy this with so-called endless strip, which arise from the herauszuspanende the chopping blade of the second machining tool corner area no longer sufficient support and thus the corner area in a small extent down so can dodge that the cleaver can not remove the full volume of herauszuspanenden corner area.

Hiervon ausgehend liegt nun der vorliegenden Erfindung die Aufgabe zugrunde, die bekannten Profilierverfahren hinsichtlich Bearbeitungsaufwand und Bearbeitungsergebnis weiter zu verbessern.Proceeding from this, the present invention is based on the object of further improving the known profiling methods with regard to processing effort and processing result.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, dass das erste Bearbeitungswerkzeug und das zweite Bearbeitungswerkzeug so zueinander angeordnet sind, dass die erste Achse und die zweite Achse in einer gemeinsamen Ebene liegen oder sich in geringem Abstand von wenigen Zentimetern kreuzen und dass die beiden Werkstückbearbeitungsbereiche jeweils zumindest teilweise einander in Baumstammquerrichtung überlappen oder aneinander angrenzen.This object is achieved in a device of the type mentioned above in that the first machining tool and the second machining tool are arranged to each other that the first axis and the second axis lie in a common plane or intersect at a small distance of a few centimeters and that the two workpiece processing areas each at least partially overlap one another in the transverse direction of the tree trunk or adjoin one another.

Hierdurch beaufschlagen die beiden Bearbeitungswerkzeuge - mit ganz geringem Zeitversatz nacheinander - den im wesentlichen gleichen Bearbeitungslängsabschnitt, wobei sie zumindest teilweise miteinander kämmen oder aneinander vorbeilaufen. Das heißt, sie arbeiten intermittierend, also zunächst setzt beispielsweise das erste Bearbeitungswerkzeug einen Sägeschnitt - gegebenenfalls kombiniert mit einem gleichzeitigen Ausspanen eines dem Sägeschnitt benachbarten Teilbereichs - , während unmittelbar anschließend das zweite Hackmesser das Ausspanen zur Erzeugung der Hackschnitzel durchführt.As a result, the two processing tools act on the essentially identical processing longitudinal section with a very small time offset, wherein they at least partially mesh with one another or pass each other. That is, they work intermittently, so first, for example, sets the first processing tool a saw cut - possibly combined with a simultaneous ausspanen a section adjacent to the saw cut - while immediately thereafter the second chopper performs the ausspanen to produce the wood chips.

Soweit hier vom Bearbeitungsbereich der Bearbeitungswerkzeuge die Rede ist, so ist damit nicht nur der Bereich gemeint, in dem das Werkstück vom Werkzeug zerspant wird, sondern die Schnittmenge aus Werkzeugflugradius und Werkstück, also der gesamte Bereich, in dem das Werkzeug den Baumstamm durchquert. Es ist unschwer erkennbar, dass ein solches Überlappen oder Aneinanderangrenzen der beiden Bearbeitungsbereiche in Baumstammquerrichtung normalerweise unmöglich ist bzw. zu sehr großen Problemen führt, da hierbei die beiden Bearbeitungswerkzeuge entweder miteinander kollidieren oder sich zumindest erheblich stören würden.As far as the processing range of the processing tools is mentioned here, so is meant not only the area in which the workpiece is machined by the tool, but the intersection of tool flying radius and workpiece, ie the entire area in which the tool traverses the tree trunk. It is readily apparent that such overlapping or juxtaposition of the two processing areas in tree trunk transverse direction is usually impossible or leads to very large problems, since in this case the two processing tools would either collide with each other or at least significantly disturb.

Um dies zu vermeiden und damit die erfindungsgemäßen Vorteile zu realisieren, weist das erste Bearbeitungswerkzeug einen kombinierten Fräser-/Sägesegmentkopf oder einen Sägesegmentkopf auf, bei dem mehrere über seinen Umfang verteilte Sägesegmente und ggf. parallel dazu Hackmesser angeordnet sind, die voneinander einen ausreichenden Abstand in Umfangsrichtung aufweisen, um ein Kämmen mit dem zweiten Bearbeitungswerkzeug zu ermöglichen bzw. um dessen Störung zu verhindern. Demgemäß ist das zweite Bearbeitungswerkzeug aus einem Fräserkopf gebildet mit mehreren über den Umfang verteilten Hackmessern, die dazu vorgesehen sind, in jeweils einen Zwischenraum zwischen benachbarte Sägesegmente und ggf. Hackmesser des ersten Bearbeitungswerkzeugs einzugreifen. Werden dann die beiden Bearbeitungswerkzeuge synchronisiert so betrieben, dass das erfindungsgemäße intermittierende Beaufschlagen des Werkstücks erfolgt, dann wird trotz der gegenseitigen Nähe der Werkzeuge deren Kollision oder Störung vermieden.To avoid this and thus to realize the advantages according to the invention, the first processing tool has a combined cutter / saw segment head or a saw segment head in which a plurality of saw segments distributed over its circumference and possibly parallel to it are arranged chopping knives which are spaced from each other by a sufficient distance Have circumferential direction to allow combing with the second processing tool or to prevent its interference. Accordingly, the second processing tool from a cutter head is formed with a plurality of circumferentially spaced chopping knives, which are intended to intervene in each case a gap between adjacent Sägesegmente and possibly chopping blade of the first processing tool. If the two processing tools are then operated in a synchronized manner so that the intermittent application of the workpiece according to the invention takes place, then despite the mutual proximity of the tools, their collision or disruption is avoided.

Vorteilhafterweise ist auch am Fräserkopf ein segmentiertes Sägeblatt vorgesehen, um auch die zweite Kante des herauszuspanenden Eckenbereichs mit einem Sägeschnitt sauber herzustellen.Advantageously, a segmented saw blade is also provided on the cutter head to produce the second edge of herauszuspanenden corner area clean with a saw cut.

Soweit vorliegend von einem Kämmen der beiden Bearbeitungswerkzeuge die Rede ist, so sei darauf verwiesen, dass dieses Kämmen natürlich nichts mit dem Kämmen von Zahnrädern zu tun hat, die sich bei dem Kämmen zur Übertragung der Antriebsbewegung berühren müssen; vielmehr dürfen sich die beiden Bearbeitungswerkzeuge gerade nicht berühren, um ein störungsfreies Bearbeiten des Eckenbereichs des Baumstamms zu ermöglichen. Die Bezeichnung "Kämmen" soll vielmehr zum Ausdruck bringen, dass beide Bearbeitungswerkzeuge abwechselnd nahezu denselben Bearbeitungsbereich beaufschlagen bzw. durchtauchen.As far as present case of a combing of the two processing tools is mentioned, it should be noted that this combing has nothing to do with the combing of gears, of course, which must be in the combs for transmitting the drive movement; Rather, the two editing tools must not touch just to allow a trouble-free editing of the corner portion of the tree trunk. The term "combing" is intended to express that both processing tools alternately act on or dive through almost the same processing area.

Und sofern hier von einem gemeinsamen Bearbeitungsbereich bzw. von nahezu identischen Bearbeitungsbereichen die Rede ist, so soll darunter verstanden werden, dass die Hackmesser des zweiten Bearbeitungswerkzeuges nicht zwangsläufig in einen vorher von den Sägesegmenten freigeschnittenen Bereich eintauchen müssen; im (theoretischen) Idealfall können die Bearbeitungsbereiche der beiden Bearbeitungswerkzeuge auch aneinander angrenzen, ohne sich zu überlappen bzw. durchdringen. Wesentlich ist jedoch, dass eine gegenseitige Störung bzw. Berührung oder Beeinflussung der beiden Bearbeitungswerkzeuge ausgeschlossen wird.And insofar as a common processing area or almost identical processing areas is mentioned here, it should be understood that the chopping blades of the second processing tool do not necessarily have to be immersed in a region that has previously been cut free from the sawing segments; In the (theoretical) ideal case, the processing areas of the two processing tools can also adjoin one another without overlapping or penetrating each other. It is essential, however, that a mutual interference or contact or interference of the two processing tools is excluded.

Zur Verdeutlichung der Tatsache, dass auch beim Stand der Technik die beiden Bearbeitungswerkzeuge den Baumstamm ebenfalls nacheinander so bearbeiten, dass insgesamt am Ende der Baumstamm in überlappenden bzw. aneinander angrenzenden Bereichen bearbeitet wurde, ohne dass sich aber die Bearbeitungsbereiche während der Bearbeitung des Baumstamms einander durchdringen bzw. in Querrichtung überlappen, wird hier zusätzlich dann von "Bearbeitungslängsabschnitt" gesprochen, wenn das erfindungsgemäße intermittierende Bearbeiten durch die beiden Werkzeuge im gleichen Längsabschnitt der Bearbeitungsvorrichtung verdeutlicht werden soll. Ein "Bearbeitungslängsabschnitt einer Bearbeitungsvorrichtung" bedeutet dabei, dass bezogen auf die Längsachse bzw. Längsrichtung einer Bearbeitungsvorrichtung (die in der Regel der Längsachse bzw. Längsrichtung der benachbarten Bearbeitungsvorrichtungen bzw. der gesamten zugehörigen Profilieranlage entspricht) die Bearbeitung durch ein Werkzeug in einem bestimmten Längenbereich erfolgt.To clarify the fact that in the prior art, the two processing tools also edit the tree trunk successively so that at the end of the tree trunk was processed in overlapping or adjoining areas, but without the processing areas penetrate each other during the processing of the tree trunk or overlap in the transverse direction, is here additionally referred to as "processing longitudinal section" when the intermittent processing according to the invention by the two tools in the same longitudinal section of the processing device to be clarified. A "processing longitudinal section of a processing device" means that with respect to the longitudinal axis or longitudinal direction of a processing device (which usually corresponds to the longitudinal axis or longitudinal direction of the adjacent processing devices or the entire associated profiling), the processing is performed by a tool in a certain length range ,

Befinden sich demnach die beiden Werkstückbearbeitungsbereiche zumindest im Wesentlichen auf dem gleichen Bearbeitungslängsabschnitt der Bearbeitungsvorrichtung, so bearbeiten die zugehörigen Werkzeuge den Baumstamm intermittierend so, dass sich die beiden Werkstückbearbeitungsbereiche durchdringen, also einander in Baumstammquerrichtung überlappen oder dass sie zumindest aneinander angrenzen.Accordingly, if the two workpiece machining areas are located at least substantially on the same machining longitudinal section of the machining device, the associated tools process the tree trunk intermittently so that the two workpiece machining areas penetrate one another overlap in tree trunk transverse direction or that they are at least adjacent to each other.

Erfindungsgemäß sind das erste Bearbeitungswerkzeug und das zweite Bearbeitungswerkzeug so zueinander angeordnet, dass die erste Achse und die zweite Achse in einer gemeinsamen Ebene liegen oder sich in geringem Abstand von wenigen Zentimetern kreuzen. Besonders vorteilhaft ist es hierbei, wenn die gemeinsame Ebene der beiden Achsen im Wesentlichen senkrecht zur Baumstammachse orientiert ist. Dadurch weisen beide Bearbeitungswerkzeuge tatsächlich keinen bzw. fast keinen Versatz zueinander in Baumstammlängsrichtung auf, d.h. sie bearbeiten den Baumstamm parallel zueinander, also quasi gleichzeitig (die einzelnen Segmente der Bearbeitungswerkzeuge wechseln sich beim Bearbeiten in unmittelbarer Folge gegenseitig ab) im selben Bearbeitungslängsabschnitt.According to the invention, the first machining tool and the second machining tool are arranged relative to each other such that the first axis and the second axis lie in a common plane or intersect at a small distance of a few centimeters. It is particularly advantageous if the common plane of the two axes is oriented substantially perpendicular to the tree trunk axis. As a result, both processing tools actually have no or almost no offset to each other in the tree trunk longitudinal direction, i. They work on the tree trunk parallel to each other, so to speak at the same time (the individual segments of the processing tools alternate in editing in direct succession) in the same processing longitudinal section.

Es ist unschwer erkennbar, dass dieses Zusammenlegen der beiden Bearbeitungsbereiche in einem gemeinsamen Bearbeitungslängsabschnitt dazu führt, dass der vom ersten Bearbeitungswerkzeug gebildete Spalt in Stammlängsrichtung nur noch ganz kurz ausfällt, da der freigelegte Eckenbereich unmittelbar anschließend vom zweiten Bearbeitungswerkzeug beaufschlagt wird. Folglich muss dieser Eckenbereich im Bereich des Spalts auch nicht mehr abgestützt werden, so dass man problemlos ohne Verwendung von Spaltkeilen auskommt. Während beim Stand der Technik der vom ersten Sägeschnitt freigelegte Spaltbereich (der so genannte vorgeritzte Spalt) in der Größenordnung von etwa einem halben Meter liegt (entsprechend in etwa dem Abstand der beiden Bearbeitungswerkzeuge zueinander), beträgt die Spaltlänge bei der erfindungsgemäßen Vorrichtung nur noch wenige Zentimeter, wobei diese Länge von den Flugkreisradien der Bearbeitungswerkzeuge, von der Breite des ersten Bearbeitungswerkzeugs und von den Bearbeitungsmaßen abhängt. Durch geeignete Wahl der Breite des ersten Bearbeitungswerkzeugs lässt sich ein Spalt und damit die nachteilige Federzunge sogar ganz vermeiden.It is readily apparent that this merging of the two processing areas in a common processing longitudinal section leads to the fact that the gap formed by the first processing tool fails in the longitudinal direction only very briefly, since the exposed corner area is immediately followed by the second processing tool. Consequently, this corner area in the region of the gap no longer needs to be supported, so that it is easy to manage without the use of riving knives. While in the prior art, the gap area exposed by the first saw cut (the so-called pre-scored gap) is on the order of about half a meter (corresponding approximately to the distance between the two processing tools), the gap length in the apparatus according to the invention is only a few centimeters This length depends on the circle radii of the machining tools, on the width of the first machining tool and on the machining dimensions. By a suitable choice of the width of the first machining tool, a gap and thus the disadvantageous spring tongue can even be completely avoided.

Ein besonderer Vorteil des in Stammlängsrichtung auf bis zu 0 reduzierten Abstandes zwischen dem Bearbeitungsbereich des ersten Bearbeitungswerkzeugs und dem Bearbeitungsbereich des zweiten Bearbeitungswerkzeugs besteht darin, dass die Formfehler bei einem Bogenschnitt minimiert werden; denn während bisher beim Versuch, in Anpassung an die Krümmung eines Baumstamms bogenfolgend zu sägen, die voneinander beabstandeten Bearbeitungsbereiche der beiden Bearbeitungswerkzeuge zu einer voneinander unabhängigen Breitenverstellung der beiden Bearbeitungswerkzeuge führen müssten, um die Krümmungsunterschiede in den beiden Bearbeitungsbereichen zu kompensieren, ist bei dem erfindungsgemäßen Zusammenlegen der beiden Bearbeitungsbereiche eine solche Kompensierung nicht mehr erforderlich, da beide Bearbeitungswerkzeuge gleichzeitig bzw. gemeinsam verstellt werden können.A particular advantage of the distance between the machining area of the first machining tool and the machining area of the second machining tool, which distance is reduced to 0 in the longitudinal direction of the stem, is that the form errors in a curved section are minimized; because while hitherto in an attempt to saw bowing in adaptation to the curvature of a tree trunk, the spaced apart processing areas of the two processing tools to an independent width adjustment of the two processing tools would have to compensate to compensate for the curvature differences in the two processing areas, such compensation is no longer necessary in the inventive merging of the two processing areas, since both processing tools can be adjusted simultaneously or together.

Besonders vorteilhaft ist es, wenn die beiden Bearbeitungswerkzeuge zusammen in einer Winkelfräsereinheit montiert sind, so dass sie dann zweckmäßigerweise über denselben Antrieb und insbesondere über ein gemeinsames Getriebe antreibbar sind und gemeinsam hinsichtlich ihrer Orientierung relativ zum Baumstamm und/oder weiteren Bearbeitungswerkzeugen verstellbar sind. Hierbei kann beispielsweise die gesamte Winkelfräser - bzw. Fräs-Säge-Einheit um eine horizontale Achse geschwenkt werden (in Verbindung mit einer servo-geregelten Höhenachse), um am zu bearbeitenden Holz entlang auf- oder abwärts ein schräg zur Tischauflage des Baumstamms verlaufendes Seitenbrett zu besäumen. Durch eine solche als Bahnsteuerung bezeichnete Einstellbarkeit ergibt sich ein deutlicher Ausbeute-Zugewinn an der Seitenware verglichen mit einer bisher üblichen tischparallelen Besäumung. Darüber hinaus ist es hierdurch möglich, dass der Schnittverlauf der Seitenware eher faserparallel verläuft.It when the two processing tools are mounted together in an angle milling unit, so that they are then expediently drivable on the same drive and in particular via a common gear and are mutually adjustable with respect to their orientation relative to the tree trunk and / or other processing tools. In this case, for example, the entire angle milling or milling-saw unit can be pivoted about a horizontal axis (in conjunction with a servo-controlled elevation axis) to the wood to be machined up or down a sloping to the table support the tree trunk extending side board tidied up. By such a designated as web control adjustability results in a significant yield gain on the sidewalls compared with a hitherto usual table-parallel trimming. In addition, this makes it possible that the cut of the side fabric runs more fiber parallel.

Ein weiteres gemeinsames Verstellen der Fräs-Säge-Einheit kann bei einem Verschwenken um eine vertikale Achse dazu ausgenutzt werden, dass ein bogenfolgender Einschnitt ohne Rückschnitt möglich ist, ohne dass man eine zusätzliche Breitenverstellung der beiden Bearbeitungswerkzeuge relativ zueinander durchführen muss.Another common adjustment of the milling-saw unit can be exploited when pivoting about a vertical axis, that a bow-cutting incision without pruning is possible without having to perform an additional width adjustment of the two processing tools relative to each other.

Durch die vorliegende Erfindung wird nicht nur eine Vorrichtung zum Bearbeiten, nämlich zum Profilieren von Baumstämmen vorgeschlagen, sondern auch ein Verfahren zum Bearbeiten, nämlich zum Profilieren von Baumstämmen. Ein beispielsweise aus der DE-A 199 60 319 bekanntes Profilierverfahren besteht aus dem Einbringen eines im Wesentlichen parallel zur Baumstammachse verlaufenden Sägeschnitt in den Baumstamm und aus dem anschließenden Ausspanen eines von zumindest im Wesentlichen von dem Sägeschnitt begrenzten, insbesondere waldkantigen Eckenbereichs. Die eingangs im Zusammenhang mit der genannten Schrift geschilderten Nachteile sollen durch das erfindungsgemäße Profilierverfahren ebenfalls vermieden werden und auch Bearbeitungsaufwand und Bearbeitungsergebnis entsprechend verbessert werden. Dies wird erfindungsgemäß dadurch erreicht, dass das Einbringen des Sägeschnittes und das Ausspanen parallel zueinander zumindest teilweise im selben Bearbeitungsabschnitt und/oder intermittierend erfolgt.The present invention proposes not only a device for processing, namely for profiling tree trunks, but also a method for processing, namely for profiling tree trunks. An example from the DE-A 199 60 319 Known profiling consists of the introduction of a substantially parallel to the tree trunk axis extending saw cut in the tree trunk and from the subsequent Ausspanen one of at least substantially limited by the saw cut, in particular forest edge portion. The disadvantages described at the outset in connection with the cited document are also to be avoided by the profiling method according to the invention and also the processing effort and processing result are correspondingly improved. This is inventively achieved in that the Insertion of the saw cut and the ausspanen parallel to each other at least partially in the same processing section and / or intermittently.

Hierdurch werden die oben bereits im Zusammenhang mit der Profilierungsvorrichtung geschilderten Vorteile erreicht. Zweckmäßigerweise erfolgt auch hier das Einbringen des Sägeschnitts und das anschließende Ausspanen durch segmentierte, ineinander greifende bzw. aneinander vorbeilaufende Bearbeitungswerkzeuge, wobei die beiden Bearbeitungswerkzeuge vorteilhafterweise gemeinsam angetrieben werden.This achieves the advantages already described above in connection with the profiling device. Expediently, here too, the introduction of the saw cut and the subsequent chip-out by segmented, interlocking or passing each other processing tools, wherein the two processing tools are advantageously driven together.

Die beiden Bearbeitungswerkzeuge beaufschlagen abwechselnd denselben Bearbeitungsbereich oder zumindest direkt aneinander angrenzende Bearbeitungsbereiche, die jedoch im selben Bearbeitungs(längs)abschnitt liegen. Durch diesen gemeinsamen Bearbeitungsbereich bzw. die direkt aneinander angrenzenden Bearbeitungsbereiche lässt sich der Sägeschnitt und das Ausspanen dadurch an die Form des Baumstamms anpassen, dass die beiden Bearbeitungswerkzeuge gemeinsam um eine gemeinsame horizontale und/oder vertikale Schwenkachse verschwenkt und/oder gemeinsam entlang einer gemeinsamen horizontalen und/oder vertikalen Achse verstellt werden.The two processing tools alternately apply the same processing area or at least directly adjoining processing areas, but in the same processing (longitudinal) section. By this common processing area or the directly adjacent processing areas, the saw cut and the Ausspanen can adapt to the shape of the tree trunk, that the two processing tools pivoted together about a common horizontal and / or vertical pivot axis and / or together along a common horizontal and / or vertical axis are adjusted.

Der besondere Vorteil im Gegensatz zu der genannten DE-A-199 60 319 liegt darin, dass durch das Einbringen des Sägeschnitts (ggf. kombiniert mit benachbartem Ausspanen) und das jeweils anschließende intermittierende Aussparen ein Spalt gebildet wird, der in Baumstammlängsrichtung eine maximale Länge in der Größenordnung von wenigen Zentimetern aufweist. Hierdurch muss der Spalt nicht mehr durch einen Spaltkeil abgestützt werden.The special advantage in contrast to the mentioned DE-A-199 60 319 lies in the fact that by introducing the saw cut (possibly combined with adjacent Ausspanen) and the respective subsequent intermittent cutting a gap is formed, which has a maximum length in the order of a few centimeters in tree trunk longitudinal direction. As a result, the gap no longer has to be supported by a splitting wedge.

Figur 1 zeigt einen Abschnitt eines Baumstamms, ein so genanntes Model 1, der von einem ersten Bearbeitungswerkzeug 2 und einem zweiten Bearbeitungswerkzeug 3 beaufschlagt wird, um einen Eckenbereich 1a (s. Figur 3a) des Baumstamms herauszuarbeiten. Hierbei besteht das erste Bearbeitungswerkzeug 2 aus einem Sägesegmentkopf mit vier über seinen Umfang verteilt angeordneten Sägesegmenten 4 sowie einem benachbart dazu angeordneten Fräserkopf 24 mit vier über den Umfang verteilt angeordneten Hackmessern 25. Jedes Sägesegment 4 bzw. Hackmesser 25 weist gegenüber dem jeweils benachbarten Sägesegment 4 bzw. Hackmesser 25 in Umfangsrichtung einen größeren Abstand auf, wie nachfolgend im Zusammenhang mit dem zweiten Bearbeitungswerkzeug 3 noch näher erläutert wird. Das erste Bearbeitungswerkzeug 2 besitzt eine erste Rotationsachse A, die im Wesentlichen senkrecht zur Längsachse C des Baumstammes 1 orientiert ist und im Ausführungsbeispiel aus Figur 1 in Vertikalrichtung verläuft. FIG. 1 shows a portion of a tree trunk, a so-called model 1, which is acted upon by a first machining tool 2 and a second machining tool 3 to a corner region 1 a (s. FIG. 3a ) of the tree trunk. In this case, the first machining tool 2 consists of a sawing segment head with four sawing segments 4 distributed over its circumference and a cutter head 24 arranged adjacently thereto with four chopping knives 25 distributed over the circumference. Each sawing segment 4 or chopping knife 25 has opposite the respectively adjacent sawing segment 4 or Cleaver 25 in the circumferential direction at a greater distance, as will be explained in more detail below in connection with the second processing tool 3. The first machining tool 2 has a first axis of rotation A, which is oriented substantially perpendicular to the longitudinal axis C of the tree trunk 1 and in the exemplary embodiment FIG. 1 in the vertical direction.

Das zweite Bearbeitungswerkzeug 3 weist einen Fräserkopf 5 mit insgesamt vier über den Umfang verteilt angeordneten Hackmessern 6 auf, die - ähnlich den Sägesegmenten 4 des Bearbeitungswerkzeugs 2 - so über den Umfang mit gegenseitigem Abstand zueinander angeordnet sind, dass sie jeweils in den Zwischenraum zwischen den benachbarten Sägesegmenten eintauchen können, ohne dass sich die beiden Bearbeitungswerkzeuge berühren. Benachbart zum Fräserkopf 5 sind zusätzliche Sägesegmente 7 vorgesehen (mit Aussparungen im Bereich der Hackmesser 6), die auch an der vom zweiten Bearbeitungswerkzeug 3 bearbeiteten Seitenkante des Models bzw. des Eckbereichs einen Sägeschnitt einbringen. Das zweite Bearbeitungswerkzeug 3 dreht sich um eine Rotationsachse B, die - ebenso wie die erste Achse A - im Wesentlichen senkrecht zur Längsachse des Baumstammes orientiert ist und im Ausführungsbeispiel aus Figur 1 in horizontaler Richtung verläuft.The second processing tool 3 has a cutter head 5 with a total of four distributed over the circumference arranged chopping knives 6, which - similar to the sawing segments 4 of the machining tool 2 - are arranged over the circumference with mutual distance to each other in the space between the adjacent Saw segments can dive without touching the two editing tools. Adjacent to the cutter head 5 additional sawing segments 7 are provided (with recesses in the region of the chopping blade 6), the also introduce a saw cut on the side edge of the model or corner area machined by the second machining tool 3. The second machining tool 3 rotates about an axis of rotation B, which - as well as the first axis A - is oriented substantially perpendicular to the longitudinal axis of the tree trunk and in the embodiment of FIG. 1 runs in a horizontal direction.

Erfindungsgemäß sind nun die beiden Rotationsachsen A und B nicht nur um 90° versetzt zueinander angeordnet, sondern sie liegen auch noch im Wesentlichen in derselben Ebene E, so dass das Bearbeitungswerkzeug 2 mit seinem Bearbeitungsbereich I und das Bearbeitungswerkzeug 3 mit seinem Bearbeitungsbereich II das Model im selben Bearbeitungslängsabschnitt III, also im selben Längsbereich des Baumstamms abwechselnd bzw. intermittierend beaufschlagen (s. hierzu Fig. 3e bis 3h sowie 5b).According to the invention, the two axes of rotation A and B are not only offset by 90 ° to each other, but they are still substantially in the same plane E, so that the machining tool 2 with its processing area I and the machining tool 3 with its processing area II, the model in the same processing longitudinal section III, so in the same longitudinal region of the tree trunk alternately or intermittently apply (see 3e to 3h and 5b).

Figur 2 zeigt nun eine ähnliche Vorrichtung und Anordnung von der Rückseite her, das heißt in Blickrichtung entgegen der Vorschubrichtung c. Der einzige Unterschied besteht darin, dass das Bearbeitungswerkzeug 2 in dieser Variante lediglich aus einem Sägesegmentkopf (unter Fortlassung des Fräserkopfes 24 aus Figur 1) besteht. Alle anderen Bauteile sind identisch mit der Variante aus Figur 1, weshalb sie auch mit denselben Bezugszeichen gekennzeichnet sind. In Figur 2 sind auch die Drehrichtungen A und B der beiden Bearbeitungswerkzeuge 2 bzw. 3 angedeutet. In dieser Ansicht kann man gut erkennen, wie gerade das Sägesegment 4a den Bearbeitungsabschnitt im Bereich des Models 1 verlassen hat und nun der Messerkopf 6a diesen Bearbeitungsabschnitt beaufschlagt, bevor das weitere Sägesegment 4b - nachdem sich der Messerkopf 6a aus dem Bearbeitungsabschnitt entfernt hat - als nächstes Bearbeitungswerkzeug diesen Bearbeitungsabschnitt beaufschlagt. Erfindungswesentlich ist vor allem die Tatsache, dass die beiden Bearbeitungswerkzeuge auf derselben Längsposition bezogen auf die Förderrichtung c der gesamten Bearbeitungsvorrichtung angeordnet sind und dort den jeweiligen Baumstamm beaufschlagen. FIG. 2 now shows a similar device and arrangement of the back, that is in the direction opposite to the feed direction c. The only difference is that the machining tool 2 in this variant only from a Sägesegmentkopf (omitting the cutter head 24 from FIG. 1 ) consists. All other components are identical to the variant FIG. 1 why they are also identified with the same reference numerals. In FIG. 2 are also the directions of rotation A and B of the two processing tools 2 and 3 indicated. In this view, one can easily see how the saw segment 4a has just left the machining section in the area of the model 1 and now the cutter head 6a acts on this machining section before the next saw segment 4b - after the cutter head 6a has moved away from the machining section - is next Machining tool applied to this processing section. Essential to the invention is above all the fact that the two processing tools are arranged on the same longitudinal position relative to the conveying direction c of the entire processing device and act there on the respective tree trunk.

Die Figuren 3a bis 3d zeigen ein teilbearbeitetes Model der Vorrichtung aus Figur 2 in perspektivischer Seitenansicht (Figur 3a), in Draufsicht (Figur 3b), in Seitenansicht (Figur 3c) und in rückwärtiger Ansicht (Figur 3d). Hier ist sehr deutlich ein sehr kurz ausfallender Spalt 7 erkennbar, der aus einem durch die Sägesegmente 4 eingebrachten, in Längsrichtung des Baumstamms verlaufenden Sägeschnitt besteht, der in Längenrichtung von einer durch den Fräserkopf 5 verursachten Ausfräsung 8 begrenzt wird. Wie man insbesondere aus der Draufsicht in Figur 3b erkennt, ist die Größe der den Spalt 7 überdeckenden Federzunge 9 minimal, so dass sie ausreichend Abstützung durch die restlichen Modelbereiche erfährt und zu ihrer Abstützung kein separater Spaltkeil erforderlich ist.The FIGS. 3a to 3d show a partially processed model of the device FIG. 2 in perspective side view ( FIG. 3a ), in plan view ( FIG. 3b ), in side view ( Figure 3c ) and in back view ( 3d figure ). Here is very clearly a very short failing gap 7 can be seen, which consists of an inserted through the saw segments 4, extending in the longitudinal direction of the log saw cut, the is delimited in the length direction by a cutout 8 caused by the cutter head 5. As can be seen in particular from the top view FIG. 3b detects, the size of the gap 7 overlapping spring tongue 9 is minimal, so that they undergo sufficient support through the remaining model areas and their support no separate riving knife is required.

Figuren 3e bis 3h zeigen demgegenüber ein teilbearbeitetes Model der Vorrichtung aus Figur 1 in perspektivischer Seitenansicht (Figur 3e), in Draufsicht (Figur 3f), in Seitenansicht (Figur 3g) und in rückwärtiger Ansicht (Figur 3h). Hierbei ist in den Figuren 3f bis 3h jeweils ein Bearbeitungsbereich I des (nicht dargestellten) ersten Bearbeitungswerkzeuges 2 und ein Bearbeitungsbereich II des (ebenfalls nicht dargestellten) zweiten Bearbeitungswerkzeuges 3 dargestellt. Die Bearbeitungsbereiche sind diejenigen Bereiche, die die zugehörigen Bearbeitungswerkzeuge zu einem bestimmten Zeitpunkt im Baumstamm beaufschlagen. Da sich beide Bearbeitungsbereiche in allen drei Ansichten (anhand der Überlagerung der beiden Schraffuren erkennbar) überlappen, ist offensichtlich, dass auch die zugehörigen Bearbeitungswerkzeuge ineinander greifend und intermittierend arbeiten müssen, da sie ansonsten miteinander kollidieren würden. Ebenso ist in diesen Figuren erkennbar, dass der Bearbeitungsbereich I so dick ausfällt, dass gar kein Spalt vorhanden ist, der dem in den Figuren 3a bis 3d dargestellten Spalt 7 entsprechen würde. Folglich fehlt auch die nachteilige Federzunge, die beim Stand der Technik eigens durch einen Spaltkeil abgestützt werden muss. FIGS. 3e to 3h In contrast, show a partially processed model of the device FIG. 1 in perspective side view ( FIG. 3e ), in plan view ( FIG. 3f ), in side view ( FIG. 3g ) and in back view ( FIG. 3h ). In this case, in FIGS. 3f to 3h, respectively, a processing area I of the first processing tool 2 (not shown) and a processing area II of the second processing tool 3 (also not shown) are shown. The machining areas are those areas that act on the associated machining tools at a specific time in the tree trunk. Since both processing areas overlap in all three views (recognizable by the superimposition of the two hatchings), it is obvious that the associated processing tools also have to work interdigitantly and intermittently, otherwise they would collide with each other. Likewise, it can be seen in these figures that the processing region I precipitates so thick that no gap is present at all which is in the FIGS. 3a to 3d represented gap 7 would correspond. Consequently, the disadvantageous spring tongue, which in the prior art must be supported by a riving knife, is also missing.

In Figur 4 ist nun das durch die erfindungsgemäße Zusammenlegung der beiden Bearbeitungswerkzeuge mögliche Prinzip der Bahnsteuerung schematisch erläutert. Dort ist das Model 1 in Seitenansicht sowie zwei Bearbeitungsvorrichtungen 11, 12 mit jeweils einem ersten Bearbeitungswerkzeug 2 und einem zweiten Bearbeitungswerkzeug 3 dargestellt, wobei jede Bearbeitungsvorrichtung zwar spiegelbildlich, aber ansonsten gleich ausgebildet ist und jeweils einen Sägesegmentkopf 4 und einen Fräserkopf 5 mit angefügtem Sägeblatt 7 aufweist. Gegenüber der in Figur 4 horizontal dargestellten Tischauflage 13 sind die Bearbeitungsebenen der Sagesegmentköpfe 4 geneigt angeordnet, so dass am zu bearbeitenden Holzmodel entlang aufwärts ein schräg zur Tischauflage 13 verlaufendes Seitenbrett 14 besäumt werden kann. Demgemäß sind die Achsen A der Sägesegmentköpfe 4 etwas gegenüber der Vertikalen geneigt, indem die Bearbeitungsvorrichtungen 11, 12 um eine horizontale Schwenkachse D in Richtung d verschwenkt worden sind. Um den Eingriffspunkt an diese Schrägstellung anzupassen, kann jede Bearbeitungsvorrichtung 11, 12 in Höhenrichtung e verstellt und so der gegenseitige Abstand verändert werden.In FIG. 4 is now the possible by merging the two processing tools according to the invention principle of path control explained schematically. There, the model 1 is shown in side view and two processing devices 11, 12, each with a first processing tool 2 and a second processing tool 3, wherein each processing device, although mirror-image, but otherwise the same design and each have a sawing segment 4 and a cutter head 5 with attached saw blade. 7 having. Opposite the in FIG. 4 Table support 13 shown horizontally, the processing levels of Sagesegmentköpfe 4 are arranged inclined so that along the wooden model to be processed along a diagonal to the table support 13 extending side board 14 can be trimmed. Accordingly, the axes A of the saw segment heads 4 are slightly inclined relative to the vertical by the processing devices 11, 12 have been pivoted about a horizontal pivot axis D in the direction d. To the point of intervention To adjust this inclination, each processing device 11, 12 adjusted in the height direction e and so the mutual distance can be changed.

Auch bei dieser schräggestellten Anordnung der aus Sägesegmentkopf 4 und Fräserkopf 5 bestehenden Bearbeitungsvorrichtung 11 bzw. 12 stehen die Achsen des Sägesegmentkopfs einerseits und des Fräserkopfs andererseits senkrecht zueinander und liegen in einer gemeinsamen Ebene, wobei jedoch die hierdurch gebildete Ebene der Bearbeitungsvorrichtung 11 im Ausführungsbeispiel aus Figur 4 nur parallel zur demgemäßen Ebene der Bearbeitungsvorrichtung 12 angeordnet ist, jedoch aufgrund der genannten Schrägstellung der beiden Bearbeitungsvorrichtungen nicht mit dieser Ebene zusammenfällt.Even with this slanted arrangement of the saw segment head 4 and cutter head 5 existing processing device 11 and 12 are the axes of the Sägesegmentkopfs on the one hand and the cutter head on the other hand perpendicular to each other and lie in a common plane, but the thus formed level of the processing device 11 in the embodiment FIG. 4 is arranged only parallel to the demgemäßen level of the processing device 12, but due to said inclination of the two processing devices does not coincide with this plane.

In Figur 5a ist in Draufsicht einerseits die Bearbeitungsvorrichtung 11 und andererseits eine ebenso aufgebaute Bearbeitungsvorrichtung 15 gezeigt. Hierbei wird ohne Rückschnitt ein bogenfolgender Einschnitt in das Model zur Herstellung einer Seitenware eingebracht. Wie aus Figur 5b erkennbar ist, die noch zwei weitere, ebenso aufgebaute Bearbeitungsvorrichtungen 16, 17 zeigt, können die linken und rechten Bearbeitungsvorrichtungen paarweise um ihre Vertikalachse in Richtung der Pfeile f geschwenkt werden, um hierdurch beim Einbringen von zwei Seitenwaren 14, 18 ein aktives Bogenschneiden durchzuführen, das heißt nicht nur die Bearbeitungsvorrichtungen in Breitenrichtung g (wie in Figur 5a gezeigt) zu verstellen, sondern auch zusätzlich um die Vertikalachse zu schwenken.In FIG. 5a is shown in plan view on the one hand, the processing device 11 and on the other hand, a likewise constructed processing device 15. Here, without a cut, a sheet-like cut is made in the model for producing a side product. How out FIG. 5b can be seen, which shows two more, equally constructed processing devices 16, 17, the left and right processing devices can be pivoted in pairs around its vertical axis in the direction of the arrows f, thereby to perform when introducing two Seitenwaren 14, 18 an active sheet cutting, the is not only the processing devices in the width direction g (as in FIG. 5a shown), but also in addition to pivot about the vertical axis.

In Figur 5b ist auch eine gemeinsame Längsrichtung h der vier Bearbeitungsvorrichtungen 11, 15, 16 und 17 dargestellt, die Teil einer Profilieranlage sind. Entlang einer in der Längsrichtung h verlaufenden Achse 33 sind für die Bearbeitungswerkzeuge 2 und 3 der Bearbeitungsvorrichtungen 11 und 17 die zugehörigen Bearbeitungslängsabschnitte III gezeigt, wobei sich die Bearbeitungswerkzeuge 2 und 3 - und damit die zugehörigen (nicht dargestellten) Werkstückbearbeitungsbereiche (I, II) - einer Bearbeitungsvorrichtung jeweils auf dem gleichen Bearbeitungslängsabschnitt III -befinden.In FIG. 5b is also a common longitudinal direction h of the four processing devices 11, 15, 16 and 17 shown, which are part of a profiling. Along an axis 33 extending in the longitudinal direction h, the associated processing longitudinal sections III are shown for the processing tools 2 and 3 of the processing devices 11 and 17, the processing tools 2 and 3 - and thus the associated workpiece processing areas (I, II) - a processing device respectively on the same processing longitudinal section III -befinden.

Zusammenfassend bietet die vorliegende Erfindung bei nahezu beliebiger Orientierung der beiden Werkzeugachse (das heißt, die Achse des ersten Bearbeitungswerkzeugs kann sowohl vertikal als auch horizontal orientiert bzw. geneigt zur Horizontalen oder zur Vertikalen angeordnet, werden, wobei jeweils die Achse des zweiten Bearbeitungswerkzeugs hierzu um 90° versetzt in der gleichen Ebene liegt) den Vorteil, durch das Zusammenlegen der beiden Bearbeitungswerkzeuge in eine, den gleichen Bearbeitungslängsabschnitt beaufschlagende Einheit eine kompakt und kurz bauende Bearbeitungsvorrichtung zur Verfügung zu stellen, die sich aufgrund ihrer geringen Länge einfach und leicht in vorhandene Bearbeitungslinien einfügen lässt.In summary, the present invention with almost any orientation of the two tool axis (that is, the axis of the first machining tool can be arranged both vertically and horizontally oriented or inclined to the horizontal or vertical, are arranged, wherein each axis of the second The processing tool is offset by 90 ° in the same plane) has the advantage of providing a compact and short design machining device by combining the two processing tools in one, the same processing longitudinal section acting unit, which is simple and easy due to their small length insert existing processing lines.

Außerdem macht die erfindungsgemäße Vorrichtung bzw. das erfindungsgemäße Verfahren einen Spaltkeil überflüssig, so dass alle damit verbundenen Risiken eines Verklemmens oder der Aufwand eines Werkzeugwechsels entfallen. Hierdurch kann auch der sonst für einen Spaltkeil erforderliche vergleichsweise dicke Spalt geringer ausfallen, was durch Erhöhung des vom Fräser auszuspanenden Hackschnitzelanteils zu einem weiteren Ausbeutegewinn und wegen der vergleichsweise geringeren Zerkleinerungsarbeit im nicht auszusägenden Bereich zu einer Verringerung der erforderlichen Antriebs- bzw. Zerspanungsleistung führt.In addition, the device according to the invention or the method according to the invention makes a riving knife superfluous, so that all associated risks of jamming or the expense of a tool change are eliminated. As a result, the comparatively thick gap otherwise required for a splitting wedge may also be smaller, which leads to a further increase in yield and, due to the comparatively lower comminution work in the non-deported area, to a reduction in the required drive or cutting power by increasing the chip fraction to be machined by the milling cutter.

Darüber hinaus wird durch die Anbringung beider Bearbeitungswerkzeuge auf einer gemeinsamen Getriebeeinheit die Gefahr eliminiert, dass beide Werkzeuge verlaufen, das heißt sich gegeneinander verstellen. Und schließlich lässt sich durch die gemeinsame Montage auf einer Getriebeeinheit auch noch eine optimale Verstellmöglichkeit der Werkzeuge am Holz entlang zur Verfügung stellen, die sich beispielsweise für eine Bahnsteuerung oder für einen bogenfolgenden Schnittverlauf ausnutzen lässt.In addition, the danger is eliminated by attaching both processing tools on a common gear unit, that both tools run, that is, adjusted against each other. And finally, by the common installation on a gear unit also an optimal adjustment of the tools along the wood can be made available, which can be exploited for example for a path control or for a bow-following cutting process.
