Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Nuten von Pappenzuschnitten nach dem Oberbegriff des Anspruchs 1.The present invention relates to a device for grooving cardboard blank according to the preamble of claim 1.

Zur Vorbereitung von Biegestellen und insbesondere scharfkantigen Abkantungen an Schachteln werden in Pappenzuschnitten dreieckige Nuten geschnitten. Der auch als Nutwinkel bezeichnete Öffnungswinkel zwischen den beiden Nutflanken ist bestimmt nach der Pappenstärke, dem Pappenmaterial und dem ggf. ein- oder beidseitigen Bezug sowie nach der Funktion der geschnittenen Nut an der aus dem Pappenzuschnitt hergestellten Schachtel.For the preparation of bending points and in particular sharp edged folds on boxes, triangular grooves are cut in cardboard blank. The opening angle, also referred to as the groove angle, between the two groove flanks is determined by the board thickness, the board material and, if applicable, the one or two-sided cover, and by the function of the cut groove on the box produced from the cardboard blank.

Eine gattungsgemäße Pappennutmaschine ist aus der CN 101200091 B bekannt. Die Nutenschneidwerkzeuge sind axial verstellbar auf parallel zur Transporttrommel liegenden Tragbalken montiert. Sie weisen jeweils zwei in einem festen Winkel schräg zueinander an einer Messeraufnahme befestigte Messer auf. Die Veränderung des Nutwinkels erfolgt durch einen zeitaufwendigen Austausch der jeweiligen Messeraufnahmen gegen solche mit einer anderen Winkellage der Messer. Aufgrund der veränderten Messerstellungen müssen außerdem noch jeweils vor bzw. nach den Nutenschneidwerkzeugen angeordnete Pappenniederhalter und Spanabweiser eingestellt werden.A generic cardboard groove machine is from the CN 101200091 B known. The Nutenschneidwerkzeuge are axially adjustable mounted on parallel to the transport drum support beams. They each have two at a fixed angle obliquely to each other attached to a blade holder knife. The change in the groove angle is effected by a time-consuming replacement of the respective blade receptacles against those with a different angular position of the knife. Due to the changed blade positions also arranged in each case before or after the Nutenschneidwerkzeugen arranged Poppenniederhalter and Spanabweiser.

Bei der in der CN 201970485 U gezeigten Pappennutmaschine ist der Tragbalken mit den Nutenschneidwerkzeugen um eine im Bereich des Trommelumfangs achsparallel liegende Achse verschwenkbar. Damit lässt sich der Anstellwinkel der Nutenschneidwerkzeuge um eine in etwa durch die Schneidenspitzen ihrer Messer verlaufende Schwenkachse zur Transporttrommel verstellen, wodurch sich deren jeweilige Schneidwinkel bzw. die sich daraus ergebenen Nutwinkel gemeinsam verändern lassen. Der Einstellaufwand für die Pappenniederhalter und die Spanabweiser aber bleibt bestehen und voneinander unabhängig eingestellte Nutwinkel sind nicht möglich.When in the CN 201970485 U The cardboard groove machine shown is the support beam with the Nutenschneidwerkzeugen about an axially parallel axis in the region of the drum circumference pivotable. Thus, the angle of the Nutenschneidwerkzeuge can be adjusted by a running approximately through the cutting tips of their knife pivot axis to the transport drum, which can be their common cutting angle or the resulting groove angle change together. The adjustment effort for the Pappenniederhalter and Spanabweiser but remains and mutually independently set groove angles are not possible.

Aufgabe der vorliegenden Erfindung ist, eine Pappennutmaschine nach dem Oberbegriff des Anspruchs 1 zu schaffen, die eine bedienungsfreundliche und separate Einstellung der Nutenschneidwerkzeuge und ihrer Peripherie ermöglicht.The object of the present invention is to provide a paperboard machine according to the preamble of claim 1, which allows an easy-to-use and separate adjustment of the Nutenschneidwerkzeuge and its periphery.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Bevorzugte Ausbildungsformen sind in den abhängigen Ansprüchen angegeben.This object is achieved by the features of the characterizing part of claim 1. Preferred embodiments are indicated in the dependent claims.

Dadurch dass die Messeraufnahme über eine im Nutenschneidwerkzeug vorliegende Bogenführung verstellbar ist, wobei der Krümmungsmittelpunkt der Bogenführung im Bereich des Trommelmantels liegt, kann an den Nutenschneidwerkzeugen der jeweils gewünschte Nutwinkel ohne Austausch der Messeraufnahmen unabhängig voneinander eingestellt werden. Das jeweilige Nutenschneidwerkzeug muss dafür nicht von dem Tragbalken genommen werden. Die Einstellung des Nutwinkels erfolgt innerhalb des jeweiligen Nutenschneidwerkzeugs, sodass der Tragbalken starr im Gestell angeordnet werden und für weitere Arbeitsmittel, wie Pappenniederhalter, Spanabweiser usw. genutzt werden kann. Durch einfaches und für den Bediener in seiner Auswirkung auf den Nutwinkel nachvollziehbares Verschwenken der Messeraufnahme lässt sich sehr schnell ein anderer Nutwinkel am jeweiligen Nutenschneidwerkzeug einstellen.Characterized in that the blade holder is adjustable over a present in Nutenschneidwerkzeug sheet guide, wherein the center of curvature of the sheet guide is in the region of the drum shell, the respective desired groove angle can be set independently of each other on the Nutenschneidwerkzeugen without replacing the knife holders. The respective groove cutting tool does not have to be removed from the support beam for this purpose. The adjustment of the groove angle is carried out within the respective groove cutting tool, so that the support beams are rigidly arranged in the frame and can be used for other work equipment, such as Pappenniederhalter, Spanabweiser and so on. By simply and for the operator in its effect on the groove angle traceable pivoting of the blade holder can be set very quickly another groove angle on each Nutenschneidwerkzeug.

Wenn der Krümmungsmittelpunkt im Bereich einer Schneidenspitze des wenigstens einen Messers liegt, erfolgt die Verstellung des Nutwinkels unabhängig von der Schnitttiefe, sodass eine Abstandskorrektur des wenigstens einen Messers zur Transporttrommel entfällt. Vorzugsweise ist durch die Bogenführung eine zur Trommeldrehachse parallele Schwenkachse für die Messeraufnahme definiert.If the center of curvature lies in the region of a cutting tip of the at least one knife, the adjustment of the groove angle takes place independently of the depth of cut, so that a distance correction of the at least one knife to the transport drum is dispensed with. Preferably, a pivot axis parallel to the drum rotation axis for the blade holder is defined by the sheet guide.

Der jeweils erforderliche Nutwinkel kann schnell und reproduzierbar eingestellt werden, wenn die Messeraufnahme oder/und die Bogenführung eine Skala mit Winkeleinteilung aufweisen, an der die sich aus bestimmten Winkelstellungen der Messeraufnahme ergebenen Nutwinkel abgelesen werden können.The respectively required groove angle can be adjusted quickly and reproducibly, if the blade holder and / or the bow guide have a scale with angle division, at which the resulting from certain angular positions of the knife holder groove angle can be read.

In konstruktiv einfacher Weise ist die Bogenführung als eine im Bogen verlaufende Anlagefläche ausgebildet, an der die Messeraufnahme durch Klemmmittel festlegbar ist. Schneidkräfte werden von der Bogenführung sicher aufgenommen und auf den im Gestell starr aufgenommenen Tragbalken übertragen.In a structurally simple manner, the sheet guide is designed as a running arc in the contact surface on which the blade holder can be fixed by clamping means. Cutting forces are safely absorbed by the sheet guide and transmitted to the support bar rigidly received in the frame.

Wenn die Messeraufnahme als Wechselteil ausgebildet ist, können verschlissene Messer schnell und einfach ausgetauscht werden. Denn ein neuer Messersatz kann auf einer zweiten Messeraufnahme vormontiert und ausgerichtet sein. Außerdem können darüber verschiedene, wahlweise einsetzbare Messerformen und -anordnungen bereit gehalten werden.If the knife holder is designed as a removable part, worn knives can be replaced quickly and easily. Because a new knife set can be pre-assembled and aligned on a second knife holder. In addition, various, optionally usable knife shapes and arrangements can be kept ready.

Mit der Möglichkeit einer Schneidtiefeneinstellung ist die Bogenführung im Wesentlichen radial zur Transporttrommel verstellbar im Nutenschneidwerkzeug aufgenommen. Diesbezügliche Einstellungen und Justierungen an der Messeraufnahme selbst sind nicht erforderlich.With the possibility of a cutting depth adjustment, the sheet guide is received in the groove cutting tool substantially radially adjustable to the transport drum. Associated settings and adjustments to the blade holder itself are not required.

Wenn die Bogenführung axial zur Transporttrommel verstellbar im Nutenschneidwerkzeug aufgenommen ist, kann die Nutposition in dem Pappenzuschnitt korrigiert werden, ohne dass das Nutenschneidwerkzeug auf dem Tragbalken verschoben werden muss.If the sheet guide is received axially adjustable to the transport drum in the Nutenschneidwerkzeug, the groove position can be corrected in the cardboard blank without the Nutenschneidwerkzeug must be moved on the support beam.

Durch ein separat von der Messeraufnahme an der Bogenführung stromabwärts vom wenigstens einen Messer angeordnetes Ableitblech werden die beim Nutenschneiden anfallenden Späne von der Transporttrommel und dem Pappenzuschnitt weggeführt, unabhängig davon ob die Pappenzuschnitte von oben nach unten oder umgekehrt an den Nutenschneidwerkzeugen vorbei transportiert werden. Da beim Verändern des Nutwinkels die Lage der Schneidenspitze des wenigstens einen Messers zur Bogenführung im Wesentlichen unverändert bleibt, ist ein Nachstellen des an der Bogenführung befestigten Ableitblechs nicht erforderlich.By a separate from the blade holder on the sheet guide downstream of at least one knife arranged Ableitblech the costs incurred during Nutenschneiden chips are guided away from the transport drum and the cardboard blank, regardless of whether the cardboard blanks are transported from top to bottom or vice versa past the Nutenschneidwerkzeugen. Since the position of the cutting tip of the at least one knife for sheet guiding remains essentially unchanged when changing the groove angle, an adjustment of the attached to the sheet guide Ableitblechs is not required.

Vorzugsweise ist das Ableitblech als Spanausheber ausgebildet, um ggf. in der Nut anhaftende Späne zu entfernen. In einer Weiterbildung ist vorgesehen, dass das Ableitblech in einen im Wesentlichen radial von der Transporttrommel wegführenden Ableitkanal übergeht, durch den die Späne aus der Pappennutmaschine herausgeführt werden können. Mit dem Vorteil einer deutlich reduzierten Staubbelastung ist der Ableitkanal mit einer Entsorgungseinrichtung für die Späne verbunden.Preferably, the deflector is designed as a chip lifter to remove possibly adhering chips in the groove. In a further development, it is provided that the deflecting plate merges into a discharge channel leading away substantially radially from the transport drum, through which the chips can be led out of the paperboard machine. With the advantage of a significantly reduced dust load, the discharge channel is connected to a disposal device for the chips.

Durch ein separat von der Messeraufnahme an der Bogenführung angeordnetes, den Pappenzuschnitt im Bereich des wenigstens einen Messers gegen den Trommelmantel niederhaltendes Andrückelement wird insbesondere die vorlaufende Kante des Pappenzuschnitts an den Trommelmantel gedrückt, wodurch eine sich zur Pappenkante erweiternde Nut vermieden wird. Da beim Verändern des Nutwinkels die Lage der Schneidenspitze des wenigstens einen Messers zur Bogenführung im Wesentlichen unverändert bleibt, ist ein Nachstellen des an der Bogenführung befestigten Andrückelements nicht erforderlich. Vorzugsweise hält das Andrückelement den Pappenzuschnitt stromaufwärts vom wenigstens einen Messer im Bereich der nachfolgend geschnittenen Nut nieder. Sich unter Umständen auf dem Pappenzuschnitt abzeichnende Schleifspuren des Andrückelements sind ohne Bedeutung, da sie als Nutspan aus dem Pappenzuschnitt herausgeschnitten werden. Unterschiedliche Pappenstärken können ohne Einstellarbeiten an dem Andrückelement verarbeitet werden, wenn dieses angefedert ist. In einer Weiterbildung ist das Andrückelement als Ableitblech ausgebildet, worüber beim Nutenschneiden anfallende Späne von der Transporttrommel abgeleitet werden.By a separately arranged from the blade holder on the sheet guide, the cardboard blank in the region of at least one knife against the drum shell holding down pressure element in particular the leading edge of the cardboard blank is pressed against the drum shell, whereby a widening to the card edge groove is avoided. Since, when changing the groove angle, the position of the cutting tip of the at least one knife for sheet guiding remains substantially unchanged, an adjustment of the pressure element attached to the sheet guide is not required. Preferably, the pressing element holds down the cardboard blank upstream of the at least one knife in the region of the subsequently cut groove. Under certain circumstances, on the cardboard blank looming marks of the pressing are of no importance, since they are cut out of the cardboard blank as a groove chip. Different board thicknesses can without adjustments to the Pressing element are processed when this is spring-loaded. In a further development, the pressure element is designed as a deflector, over which shavings arising during groove cutting are derived from the transport drum.

From a feeder 101 the inlet 14 supplied cardboard blanks 2 are conveyed by the belt 51 promoting effect on the drum shell and in the transport direction 11a in an approximately 180 ° rotation of the transport drum 11 from the bottom vertex of the transport drum 11 lying inlet 14 for lying in the upper vertex outlet 15 promoted and thereby past the Nutenschneidwerkzeugen 72, where with appropriately shaped slot knives 71 a chip 6 with, for example, substantially triangular cross-section of the paperboard cut 2 is cut out.

Die Zuführeinrichtung 101 in Fig. 1 weist ein Pappenmagazin 102 auf, das einen Stapel 4 von übereinander liegenden Pappenzuschnitten enthält. Der jeweils unterste Pappenzuschnitt 2 wird von einem ersten Pappenschieber 104.1 unter einen vorderen Anschlag 103 ausgeschoben und zu einer Zwischenposition 105 überführt, aus der der Pappenzuschnitt 2 mit einem zweiten Pappenschieber 104.2 unter Ausrichtung an äußeren Führungsschienen 106 dem Einlauf 14 zugeführt wird. Die Pappenschieber 104.1, 104.2 sind in einem festen Abstand miteinander gekoppelt und werden mit einem konstanten Förderhub 107 gleich diesem Abstand taktgemäß vor und zurück bewegt. Die Zuführgeschwindigkeit ist dabei gleich der Drehgeschwindigkeit der Transporttrommel 11 oder liegt etwas darüber, sodass die Pappenzuschnitte 2 quasi zwangsweise in den Einlauf 14 zwischen Transporttrommel 11 und Riemen 51 eingeschoben werden.The feeder 101 in Fig. 1 has a paperboard magazine 102 containing a stack 4 of stacked cardboard blank. The respective lowermost cardboard blank 2 is pushed out by a first board slider 104.1 under a front stop 103 and transferred to an intermediate position 105, from which the board blank 2 is fed to the inlet 14 with a second board slider 104.2 aligned with outer guide rails 106. The board slides 104.1, 104.2 are coupled together at a fixed distance and are moved in a constant delivery stroke 107 equal to this distance clockwise back and forth. The feeding speed is equal to the rotational speed of the transport drum 11 or is slightly above it, so that the cardboard blanks 2 quasi forcibly inserted into the inlet 14 between the transport drum 11 and belt 51.

Die Ausfuhr 111 in Fig. 1 weist einen schräg nach vorn abfallenden Auslagetisch 112 auf, auf den die aus dem Auslauf 15 auslaufenden, fertig genuteten Pappenzuschnitte 3 abgeworfen und zum Stapel 5 übereinander gelegt werden. Durch die Anordnung des Auslaufs 15 im oberen Scheitelpunkt der Transporttrommel 11 liegen die geschnittenen Nuten 3a in den auslaufenden Pappenzuschnitten 3 oben und sind dadurch vom Bediener einsehbar.The export 111 in Fig. 1 has an obliquely sloping forward delivery table 112 to which the expiring from the outlet 15, finished grooved cardboard cuttings 3 are dropped and stacked to stack 5. Due to the arrangement of the outlet 15 in the upper vertex of the transport drum 11, the cut grooves 3a in the leaking cardboard blank 3 are above and are thus visible to the operator.

Wie aus Fig. 1 ersichtlich sind die Rollen 54 derart um die Transporttrommel 11 angeordnet, dass sich insgesamt drei Bereiche größter Annäherung der zwischen den Rollen 54 liegenden Trume und dem an der Transporttrommel 11 anliegenden Riemenabschnitt ausbilden. In diesen Bereichen können die Nutenschneidwerkzeuge 72 angeordnet sein. Die Nutenschneidwerkzeuge 72 sind auf parallel zur Transporttrommel 11 liegenden Tragbalken 36, 37 montiert. Es können mehrere Nutenschneidwerkzeuge 72 nebeneinander montiert sein. Durch die Anordnung auf zwei in Transportrichtung 11a hintereinander liegenden Tragbalken 36, 37 können sehr dicht beieinander liegende Nuten 3a eingebracht werden.How out Fig. 1 it can be seen that the rollers 54 are arranged around the transport drum 11 such that a total of three areas form the greatest approximation of the strands lying between the rollers 54 and the belt section abutting on the transport drum 11. In these areas, the groove cutting tools 72 may be arranged. The Nutenschneidwerkzeuge 72 are mounted on parallel to the transport drum 11 support beams 36, 37. Several groove cutting tools 72 may be mounted side by side. By arranging for two in the transport direction 11a consecutive support beams 36, 37 very closely spaced grooves 3a can be introduced.

Fig. 2a und 2b zeigen das erfindungsgemäß ausgebildete Nutenschneidwerkzeug 72 aus Fig. 1 im vergrößerten Maßstab. Es weist einen Träger 73 auf, welcher mit einem Klemmstück 74 auf dem Tragbalken 36 festsetzbar ist. Auf dem Träger 73 ist ein über eine Exzenterschraube 75a axial zur Transporttrommel 11 fein einstellbarer Schlitten 75 geführt und festsetzbar. Dieser trägt wiederum einen über eine Rändelschraube 76a im Wesentlichen radial zur Transporttrommel 11 verschieblichen und ebenso festsetzbaren Schlitten 76, an dem sich die Bogenführung 77 befindet. An ihrer bogenförmigen Anlagefläche 77a liegt mit komplementär gekrümmter Anlagefläche eine Messeraufnahme 78 an, die durch eine Klemmschraube 79 und Unterlegscheibe 79a an der Bogenführung 77 festgesetzt ist. An der Messeraufnahme 78 ist schließlich das Nutmesser 71 befestigt. Fig. 2a and 2b show the inventively designed Nutenschneidwerkzeug 72 Fig. 1 on an enlarged scale. It has a carrier 73, which can be fixed with a clamping piece 74 on the supporting beam 36. On the carrier 73 a via an eccentric 75a axially to the transport drum 11 finely adjustable carriage 75 is guided and fixable. The latter in turn carries a carriage 76, which is displaceable substantially radially relative to the transport drum 11 and can likewise be fixed by means of a knurled screw 76 a, on which the sheet guide 77 is located. At its arcuate contact surface 77a is located with complementary curved contact surface on a blade holder 78, which is fixed by a clamping screw 79 and washer 79a to the sheet guide 77. At the knife holder 78 finally the grooved knife 71 is attached.

Der Krümmungsmittelpunkt 81 der Bogenführung 77 liegt in der Schneidenspitze 71 a des Nutmessers 71, quasi am Umfang der Transporttrommel 11. Nach Lösen der Klemmschraube 79 kann die Messeraufnahme 78 in eine andere Winkelstellung gemäß Skala 80 verstellt werden (vgl. Fig. 2a und 2b). Dabei wird die Messeraufnahme 78 und mit ihr das Nutmesser 71 um eine durch den Krümmungsmittelpunkt 81 und parallel zur Transporttrommel 11 verlaufende Schwenkachse verschwenkt. Die Position der Schneidenspitze 71 a und damit ihr Abstand von der Transporttrommel 11 verändern sich dabei nicht. Die über die Rändelschraube 76a einstellbare Schnitttiefe bleibt konstant, während durch die veränderte Winkelstellung der Messeraufnahme 78 an der Bogenführung 77 ein anderer Nutwinkel resultiert.The center of curvature 81 of the sheet guide 77 is located in the cutting tip 71 a of the groove knife 71, virtually on the circumference of the transport drum 11. After loosening the clamping screw 79, the blade holder 78 can be adjusted to a different angular position according to scale 80 (see. Fig. 2a and 2b ). In this case, the blade holder 78 and with it the grooving knife 71 by a through the center of curvature 81 and parallel to the transport drum 11 extending pivot axis pivoted. The position of the cutting tip 71 a and thus their distance from the transport drum 11 do not change. The depth of cut which can be set via knurled screw 76a remains constant, while due to the changed angular position of blade holder 78 on sheet guide 77, a different groove angle results.

An der nach der gewünschten Schnitttiefe radial einstellbaren Bogenführung 77 befindet sich stromabwärts vom Nutmesser 71 ein Ableitblech 82 für die beim Nutenschneiden anfallenden Späne 6, dessen vorderes Ende als Spanausheber bis nahe der Schneidenspitze 71 a des Nutmessers 71 positioniert ist und am anderen Ende in einen über das Nutenschneidwerkzeug 72 hinweg und im Wesentlichen radial zur Transporttrommel 11 verlaufenden Ableitkanal 83 übergeht, welcher mit einer nicht weiter dargestellten Späneentsorgungseinrichtung verbunden werden kann. Beim Ändern des Nutwinkels bleibt das Ableitblech 82 in seiner festgelegten Position.At the desired depth of cut radially adjustable bow guide 77 is downstream of the grooving knife 71 a Ableitblech 82 for the costs incurred in Nutenschneiden chips 6, the front end is positioned as chip lifter to near the cutting tip 71 a of the notch 71 and at the other end in a the Nutenschneidwerkzeug 72 away and substantially radially to the transport drum 11 extending discharge channel 83 merges, which can be connected to a chip disposal device not shown. When changing the groove angle the deflector 82 remains in its fixed position.

Stromaufwärts vom Nutmesser 71 ist ein Pappenniederhalter 84 vorgesehen. Er ist separat von der Messeraufnahme 78 an einem an der Bogenführung 77 angeordneten Halter 87 schwenkbar aufgenommen und drückt von einer Druckfeder 85 beaufschlagt den Pappenzuschnitt 2 im Bereich des Nutmessers 71 gegen den Trommelmantel, wodurch eine an der Pappenkante einwandfrei geschnittene Nut gewährleistet ist. Das gegen die Pappenzuschnitte 2 drückende Ende des Pappenniederhalters 84 wirkt als Andrückelement ausschließlich im Bereich der nachfolgend ausgeschnittenen Nut. Außerhalb des Andrückpunkts verbreitert sich der Pappenniederhalter 84 zum Ableitblech 86 für beim Nutenschneiden ggf. nach unten herunterfallender Späne.Upstream of the grooving knife 71, a poppie-down holder 84 is provided. It is received separately from the blade holder 78 on a arranged on the sheet guide 77 holder 87 pivotally and presses by a compression spring 85 acted upon the cardboard blank 2 in the region of the groove knife 71 against the drum shell, whereby a properly cut on the card edge groove is guaranteed. The pressing against the cardboard blank 2 end of the poppy lowermost 84 acts as a pressing element exclusively in the area of the subsequently cut out groove. Outside the pressure point, the poppy-down holder 84 widened to the deflecting plate 86 for chips that may possibly fall down during groove cutting.

Fig. 3 und 4 zeigen das Nutenschneidwerkzeug 72 aus unterschiedlichen Perspektiven jeweils mit Blick auf das Nutmesser. In Fig. 3 ist die Nutenschneidwerk 72 mit dem einteiligen Nutmesser 71 bestückt. Es ist ein Messer mit zwei zu einem V-förmigen Flügel verbundenen jeweils außen angeschliffenen Klingen 71 b,c, welche durch eine Brücke zu einem geschlossenen Ringkörper als Späneableitkanal verbunden sind. Das Nutmesser 71 lässt sehr einfach nachschleifen und über einen einfachen Schiebesitz hinsichtlich einer konstanten Schneidenspitze 71a an der Messeraufnahme 78 justieren. Es müssen keine einzelnen Messerklingen zueinander eingestellt werden. Die zum V verbundenen Klingen heben die Späne sicher aus der Nut 3a und leiten sie von dem Pappenzuschnitt 2 bzw. der Transporttrommel 11 ab. Durch Stutzen der Schneidenspitze 71 a können mit dem Nutmesser 71 auch trapezförmige Nuten geschnitten werden. 3 and 4 show the Nutenschneidwerkzeug 72 from different perspectives, each with a view of the grooving knife. In Fig. 3 the grooving cutter 72 is equipped with the one-piece grooved cutter 71. It is a knife with two connected to a V-shaped wings each outer ground blades 71 b, c, which are connected by a bridge to a closed ring body as chip removal channel. The grooving knife 71 is very easy to grind and adjust over a simple sliding seat with respect to a constant cutting tip 71a on the blade holder 78. It is not necessary to set individual knife blades to each other. The blades connected to the V lift the chips safely out of the groove 3a and guide them away from the cardboard blank 2 or the transport drum 11. By cutting the cutting tip 71 a can be cut with the grooving knife 71 and trapezoidal grooves.

In Fig. 4 ist die aus den anderen Figuren bekannte Messeraufnahme 78 mit dem Nutmesser 71 ersetzt durch eine die gleiche Schnittstelle zur Bogenführung 77 aufweisende Messeraufnahme 78', die mit zwei einzelnen Messern 88 a, b bestückt ist. Damit können ebenfalls Nuten 3a mit im Wesentlichen dreieckigen Querschnitt geschnitten werden.In Fig. 4 is known from the other figures knife holder 78 with the grooved knife 71 replaced by a the same interface to the sheet guide 77 having blade holder 78 ', which is equipped with two separate blades 88 a, b. This also grooves 3a can be cut with a substantially triangular cross-section.

Durch die Ausbildung der Messeraufnahme 78 als Wechselteil können verschlissene Nutmesser 71 bzw. 88 a, b schnell ausgetauscht werden. Außerdem können darüber Messersonderformen und/oder spezielle Messeranordnungen eingesetzt werden, um beispielsweise halbrundförmig geschnittene Nuten, hinterschnittene Nuten wie Schwalbenschwanznuten usw. herzustellen. Auch können hierüber Schlitz- und Perforiermesser am Nutenschneidwerkzeug 72 zum Einsatz kommen.Due to the design of the blade holder 78 as a removable part worn splitter blades 71 and 88 a, b can be replaced quickly. In addition, it can Messersonderformen and / or special knife assemblies are used to produce, for example, semi-circular cut grooves, undercut grooves such as dovetail grooves, etc. Slot and perforating knives on the groove cutting tool 72 can also be used here.
