Description

Die Erfindung betrifft eine Schneidemaschine zum selbsttätigen Beschneiden von Broschuren, Zeitschriften und Büchern, mit auf- und abbewegbaren Messern, wobei jedem Messer eine Pressleiste sowie ein feststehendes Gegenmesser zugeordnet ist, und mit einer Transportvorrichtung für den Weitertransport der Broschuren, Zeitschriften und Bücher.The invention relates to a cutting machine for automatic Trimming brochures, magazines and books, with knives that can be moved up and down, whereby each knife has one Press bar and a fixed counter knife assigned is, and with a transport device for further transport of brochures, magazines and books.

Schneidemaschinen dieser Art sind seit langem bekannt und haben sich in der Praxis an sich bewährt. Das Prinzip solcher Schneidemaschinen zeigt die CH-A-34 04 79 des Anmelders aus dem Jahr 1959. Die hier offenbarte Schneidemaschine besitzt einen auf- und abbewegbaren Schneideblock mit drei Messern, die auf zwei bezüglich der Bewegungsrichtung der Broschuren hintereinander angeordneten Schneidstationen derart verteilt sind, dass mit einem Messer ein Frontschnitt und mit zwei anderen Messern je ein Kopf- und Fussschnitt ausgeführt werden können. Der Schneideblock, die Transportvorrichtung und bewegliche Anschläge sind mit einem gemeinsamen Antriebsmittel verbunden. Obwohl diese Schneidemaschine in einzelnen Teilen weiterentwickelt wurde, hat sich bisher der Grundaufbau nicht geändert. Solche Schneidemaschinen werden auch Trimmer oder Dreischneider-Automaten genannt. Sie erlauben ein automatisches Schneiden auch dicker Papierprodukte mit einer Leistung von beispielsweise sechs Exemplaren pro Sekunde. Der mit den Messern ausgeführte Schnitt wird auch Scherenschnitt genannt und erfolgt so, dass das Schneidmesser sich über die Schneidkante des Gegenmesser bewegt. Vorteilhaft ist bei diesem Schnitt die lange Messerstandzeit, die beispielsweise im Vergleich mit dem Schneiden mittels Schneidleisten wesentlich länger ist. Bedingung ist jedoch eine exakte Messerführung. Zum Beschneiden von Produkten auf drei Seiten sind Zudem zwei Stationen zwingend.Cutting machines of this type have long been known and have proven itself in practice. The principle of such Cutting machines shows the applicant's CH-A-34 04 79 the year 1959. The cutting machine disclosed here has an up and down movable cutting block with three knives, the two on the direction of movement of the brochures distribution stations arranged one behind the other distributed in this way are that a front cut with one knife and two others A head and foot cut are made for each knife can. The cutting block, the transport device and movable Stops are with a common drive means connected. Although this cutting machine in individual parts The basic structure has not yet been further developed changed. Such cutting machines are also trimmers or Called three-cutters. They allow automatic Cutting even thick paper products with one performance of, for example, six copies per second. The one with the A cut made by knives is also called a silhouette and is done so that the cutting knife extends over the cutting edge the counter knife moves. This is advantageous Cut the long knife life, for example, in comparison with cutting using cutting strips essential is longer. Precondition, however, is an exact knife guide. There are also two for trimming products on three sides Mandatory stations.

Bei der genannten Schneidemaschine ist der Kraftfluss vergleichsweise ungünstig und sind Verformungen unausweichlich. Ferner sind die Steuerbewegungen umständlich und ist nur eine vergleichsweise leichte Presskraft möglich. Schliesslich ist die Zugänglichkeit eingeschränkt und die Schmierung aufwendig.The power flow in the cutting machine mentioned is comparative unfavorable and deformations are inevitable. Furthermore, the tax movements are cumbersome and is only one comparatively light pressing force possible. Finally is accessibility is restricted and lubrication is complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidemaschine der genannten Art zu schaffen, welche die genannten Nachteile vermeidet und die trotzdem kostengünstig herstellbar und funktionstüchtig ist.The invention has for its object a cutting machine to create the kind mentioned, which the named Avoids disadvantages and which can still be produced inexpensively and is functional.

Die Aufgabe ist bei einer gattungsgemässen Schneidemaschine dadurch gelöst, dass die auf- und abbewegbaren Messer unter den Gegenmessern angeordnet sind und zum Schneiden von unten gegen die Gegenmesser bewegbar sind. Im Gegensatz zum Stand der Technik sind die Messer somit nicht über den festen Gegenmessern sondern unterhalb dieser angeordnet. Dadurch ergeben sich insbesondere die nachfolgenden zahlreichen Vorteile.

  • Ohne Verschmutzungsgefahr für die Produkte durch herabtropfendes Oel, können alle bewegten Teile in einem Oelbad angeordnet werden. Dadurch können die Messerführungen optimal mit Oel geschmiert werden, wodurch der Verschleiss und auch das Messerspiel wesentlich verringerbar sind.
  • Die Gegenmesser lassen sich auf einfache Weise mit einem Support wegschwenken, wodurch die Messer für den Messerwechsel besser zugänglich sind und zudem die Verletzungsgefahr gesenkt werden kann.
  • Die Gegenmesser lassen sich einfacher als bisher durch ein horizontales Verschieben eines Supports gegen die Schneidmesser einstellen.
  • Die Schneidmesser können in einfacher Weise und ohne Verletzungsgefahr nach oben ausgebaut werden.
  • Da keine Schneidkräfte über das Gestell übertragen werden müssen, ist infolge des direkteren Kraftflusses bei gleichzeitig leichterem Maschinengestell eine wesentlich höhere Presskraft möglich.
  • Da das bisher über den Transportbändern angeordnete Joch für die Messer wegfällt, ist die Sicht auf den Schneidtransport besser und dadurch ist auch ein einfacheres und schnelleres Einrichten möglich.
  • Da die fixen Kanten der Gegenmesser oben liegen, hat die Dicke der Produkte keinen Einfluss auf den Oberbänderhub. Dies erlaubt es, die Vorrichtung für den Oberbänderhub einfacher zu gestalten.
  • Gefährlich Quetschstellen im Bereich der Anschläge und des Schneidtransports können lokal abgesichert werden, so dass ohne Verletzungsgefahr ein Einrichten ohne zusätzliche Schutzhaube möglich ist.
  • Der Wegfall des Joches für die Messer hat ferner den Vorteil, dass die Bauhöhe beispielsweise um 300 mm verringert werden kann.
  • Schliesslich ist ein Kanal für die Späneabsaugung konstruktiv einfacher realisierbar und damit kann die bisher notwendige vergleichsweise grosse Abdeckhaube wegfallen.
The object is achieved in a cutting machine of the generic type in that the blades which can be moved up and down are arranged under the counter blades and can be moved against the counter blades for cutting from below. In contrast to the prior art, the knives are therefore not arranged above the fixed counter knives but below them. This results in the following numerous advantages in particular.
  • All moving parts can be arranged in an oil bath without risk of contamination of the products by dripping oil. As a result, the knife guides can be optimally lubricated with oil, which means that wear and knife play can be significantly reduced.
  • The counter knives can be easily swiveled away with a support, which makes the knives more accessible for changing knives and also reduces the risk of injury.
  • The counter knives can be adjusted more easily than before by horizontally moving a support against the cutting knives.
  • The cutting blades can be removed easily and without risk of injury.
  • Since no cutting forces have to be transmitted via the frame, a much higher pressing force is possible due to the more direct force flow with a lighter machine frame.
  • Since the yoke for the knives, which was previously arranged above the conveyor belts, is no longer available, the view of the cutting transport is better and this also makes setup easier and faster.
  • Since the fixed edges of the counter knives are on top, the thickness of the products has no influence on the upper belt stroke. This allows the device for the upper belt stroke to be made simpler.
  • Dangerous crushing points in the area of the stops and the cutting transport can be secured locally so that it can be set up without an additional protective hood without the risk of injury.
  • Eliminating the yoke for the knives also has the advantage that the overall height can be reduced, for example, by 300 mm.
  • Finally, a duct for the chip extraction can be implemented more easily in terms of construction and the comparatively large cover hood previously required can thus be omitted.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung und der Zeichnung.Further advantageous features result from the dependent ones Claims, the description below and the Drawing.

Die Figur 1 zeigt schematisch einen Bandförderer 13, mit dem zu beschneidende Produkte 41 einzeln und mit einem Rücken 41a voraus der Schneidemaschine 1 zugeführt werden. Die Transportrichtung ist mit dem Pfeil 7 angedeutet. Für den Transport der Produkte 41 in der Schneidemaschine 1 ist eine Transportvorrichtung 6 vorgesehen, die Unterbänder 11 sowie Oberbänder 12 aufweist, die jeweils über Rollen 10 umgelenkt sind. Diese Transportvorrichtung 6 transportiert die Produkte 41 von einer ersten Schneidstation zu einer zweiten Schneidstation. In der ersten Schneidstation wird mit dem in Figur 1 gezeigten Schneidelement 14 jeweils ein Frontschnitt ausgeführt. In der zweiten Schneidstation wird mit zwei weiteren Schneidelementen 14' jeweils ein Kopfschnitt und ein Fussschnitt ausgeführt. Diese weiteren Schneidelemente 14' sind in Figur 2 gezeigt. Die Schneidelemente 14 und 14' sind im wesentlichen gleich ausgebildet, das Schneidelement 14 erstreckt sich jedoch quer zur Transportrichtung 7, während die Schneidelemente 14' sich parallel und im Abstand zueinander zur Transportrichtung 7 erstrecken. Jedem Schneidelement 14 und 14' ist jeweils ein festes Gegenmesser 5 zugeordnet. Der Transport der Vorrichtung 6 ist selbstverständlich auf denjenigen des Bandförderers 13 abgestimmt. Für die beiden genannten Schneidstationen sind Anschläge 58 (Figur 5) sowie hier nicht gezeigte Mittel zum Ausrichten der Produkte 41 vorgesehen. Um ein Zurückfallen der Druckprodukte 41 an den Anschlägen zu verhindern, sind gemäss Figur 2 Bürsten 36 vorgesehen, die oberseitig an den Produkten 41 anliegen.FIG. 1 shows schematically a belt conveyor 13 with which Products to be trimmed 41 individually and with a back 41a be fed to the cutting machine 1 in advance. The direction of transport is indicated by arrow 7. For the transport of the products 41 in the cutting machine 1 is one Transport device 6 provided, the lower belts 11 and Has top bands 12, each deflected via rollers 10 are. This transport device 6 transports the products 41 from a first cutting station to a second cutting station. In the first cutting station, the one shown in FIG shown cutting element 14 each performed a front cut. In the second cutting station there are two more Cutting elements 14 'each have a head cut and a foot cut executed. These are further cutting elements 14 ' shown in Figure 2. The cutting elements 14 and 14 'are in essentially the same, the cutting element 14 extends however, transversely to the transport direction 7, while the Cutting elements 14 'are parallel and at a distance from one another extend to the transport direction 7. Each cutting element 14 and 14 'is assigned a fixed counter knife 5. Of the Transport of the device 6 is of course on those of the belt conveyor 13 matched. For the two mentioned Cutting stations are stops 58 (Figure 5) as well as here Means, not shown, for aligning the products 41 are provided. To prevent the printed products 41 from falling back at the stops to prevent, brushes 36 are provided according to FIG. 2, which are on the top of the products 41.

Wesentlich ist nun, dass die drei Gegenmesser 5 gestellfest so angeordnet sind, dass ihre Schneidkante 42 jeweils unten und über dem zu schneidenden Produkt 41 angeordnet ist. Die Gegenmesser 5 befinden sich somit jeweils über einem Schneidelement 14 bzw. 14'. Schneidelemente 14 und 14' schneiden somit von unten nach oben und die Produkte 41 werden jeweils mit ihrer Oberseite 43 an die Gegenmesser 5 angelegt. Die Figur 1 Zeigt für den Frontschnitt diese Anordnung. Wie ersichtlich ist die Schneidkante 42 des Gegenmesers 5 oben und die Schneidkante 9 des Schneidelementes 14 unten angeordnet. Für den Frontschnitt ist die Schneidkante 9 nach oben bis zur Überlappung mit der Schneidkante 42 und wieder zurück bewegbar. In Figur 1 ist der Frontschnitt für das Produkt 41' bereits durchgeführt und nach dem vollständigen Rückzug der Schneidkante 9 kann für den Frontschnitt mit dem Bandförderer 13 ein weiteres Produkt 41 der Transportvorrichtung 6 Zugeführt werden.It is now essential that the three counter knives 5 are fixed to the frame are arranged so that their cutting edge 42 each below and is placed over the product 41 to be cut. The Counter knife 5 are thus each above a cutting element 14 or 14 '. Cut cutting elements 14 and 14 ' thus from bottom to top and the products 41 are each with its top 43 against the counter knife 5. The figure 1 Shows this arrangement for the front cut. As can be seen is the cutting edge 42 of the counter knife 5 above and the cutting edge 9 of the cutting element 14 arranged below. For the front cut, the cutting edge 9 is up to Overlap with the cutting edge 42 and movable back again. In Figure 1, the front cut for the product 41 'is already carried out and after the complete withdrawal of the Cutting edge 9 can be used for the front cut with the belt conveyor 13 another product 41 fed to the transport device 6 become.

Die Schneidelemente 14 und 14' weisen jeweils ein Lagergehäuse 30 auf, das eine Füllwanne mit einem mit Oel gefüllten Innenraum 39 bildet. In diesem Innenraum 39 sind jeweils ein Messer 3 und eine Pressleiste 4 gelagert. Jedem Messer 3 ist eine Pressleiste 4 zugeordnet. Beide sind jeweils in den Richtungen des Doppelpfeils 44 vertikal auf- und abbewegbar.The cutting elements 14 and 14 'each have a bearing housing 30 on that a filling pan with an interior filled with oil 39 forms. In this interior 39 there are one Knife 3 and a pressure bar 4 stored. Each knife is 3 a press bar 4 assigned. Both are in the Directions of the double arrow 44 vertically up and down.

Die Figuren 3 und 4 zeigen schematisch den Antrieb für die Hubbewegung eines Messers 3, das hier den Kopfschnitt ausführt. Ein Kurvenrad 17 ist in einem Maschinengestell 31 gelagert und wird mittels einer Hauptwelle 19 in Richtung des Pfeils 45 angetrieben. Ein Träger 15 des Messers 3 ist zur Ausführung eines Schwingschnittes im Maschinengestell 31 gelagert. Der Träger 15 ist zudem an einem einarmigen Hebel 23 geführt, der um eine gestellfeste Achse 24 begrenzt verschwenkbar ist und mit einem Drehgelenk 25 mit dem Träger 15 verbunden ist. Ein weiterer Hebel 16 ist wie ersichtlich als zweiarmiger Winkelhebel ausgebildet und greift mit einer Kurvenrolle 20 in eine Steuerkurve 18 des Kurvenrades 17 ein. Der Hebel 16 ist an einer Achse 21 des mit dem Maschinengestell 31 verbundenen Lagergehäuses 30 schwenkbar gelagert und mit einem Gelenk 22 mit dem Träger 15 verbunden. Die Figur 3 zeigt die obere Stellung des Messers 3. Die Kurve 18 ist so ausgebildet, dass beim Weiterdrehen des Kurvenrades 17 in Richtung des Pfeils 45 der Hebel 16 im Uhrzeigersinn um die feste Achse 21 verschwenkt wird. Das Messer 3 mit dem Schneidmesser 8 wird dadurch nach unten in eine vorbestimmte untere Position bewegt. Nach einer Drehung von etwa 180° des Kurvenrades wird der Hebel 16 im Gegenuhrzeigersinn verschwenkt und das Messer 3 wieder nach oben zur Durchführung des Schnittes bewegt. Das Messer 3 wird somit kontinuierlich mit einem Schwingschnitt auf- und abbewegt. Bei jeder vertikal nach oben gerichteten Bewegung wird ein Schnitt durchgeführt, wobei die Schneidkante 9 mit einer Schneidkante 42 eines Gegenmessers 5 zusammenarbeitet und dieses überlappt. Die bewegten Teile des Messerantriebs, also insbesondere die Hebel 16 und 23 und das Kurvenrad 17, befinden sich hierbei im Oe1, das sich in der Kammer 39 befindet. Da sich die Schneidmesser 8 über diesem Oelbad befinden, ist eine Verschmutzung der Produkte 41 durch Oeltropfen ausgeschlossen. Der Antrieb für die Pressleiste 4 kann im wesentlichen gleich sein wie der anhand der Figur 3 erläuterte Antrieb für die Messer 3. Wesentlich ist jedoch, dass jeweils ein Messer 3 und eine Pressleiste 4 als kompaktes Schneidelement 14 bzw. 14' ausbildbar sind. Die Pressleisten 4 sind so gesteuert, dass bei der Ausübung eines Schnittes die Produkte 41 zuerst gegen das Gegenmesser 5 bzw. die Gegenmesser 5 gepresst und anschliessend geschnitten werden. Ein Joch zwischen den Schneidelementen 14 und 14' ist nicht erforderlich. Dadurch ist ein sehr kurzer und formschlüssiger Kraftfluss für den Hub möglich.Figures 3 and 4 show schematically the drive for the Stroke movement of a knife 3, which performs the head cut here. A cam wheel 17 is mounted in a machine frame 31 and is by means of a main shaft 19 in the direction of Arrow 45 driven. A carrier 15 of the knife 3 is for Execution of a swing cut stored in the machine frame 31. The carrier 15 is also on a one-armed lever 23 performed, the limited pivotable about a frame-fixed axis 24 and with a pivot joint 25 with the carrier 15 connected is. Another lever 16 is shown as two-arm angle lever designed and engages with a cam roller 20 into a control cam 18 of the cam wheel 17. The lever 16 is on an axis 21 of the machine frame 31 connected bearing housing 30 pivotally mounted and connected with a hinge 22 to the carrier 15. Figure 3 shows the upper position of the knife 3. The curve 18 is like this formed that when turning the cam wheel 17 in Direction of arrow 45 the lever 16 clockwise around the fixed axis 21 is pivoted. The knife 3 with the Cutting knife 8 is thereby down to a predetermined lower position moves. After a rotation of about 180 ° Cam 16, the lever 16 is pivoted counterclockwise and the knife 3 back up to carry out of the cut moves. The knife 3 is thus continuous moved up and down with a swing cut. With each vertical upward movement a cut is made the cutting edge 9 with a cutting edge 42 of a Counter knife 5 works together and this overlaps. The moving parts of the knife drive, in particular the lever 16 and 23 and the cam wheel 17 are here in the Oe1 located in chamber 39. Because the cutting knife 8 above this oil bath is a pollution of products 41 excluded by oil drops. The drive for the pressure bar 4 can be essentially the same as the drive for the knives 3 explained with reference to FIG. 3. However, it is essential that one knife 3 and one each Press bar 4 can be formed as a compact cutting element 14 or 14 ' are. The pressure bars 4 are controlled so that exercising a cut the products 41 first against that Counter knife 5 or the counter knife 5 pressed and then get cut. A yoke between the cutting elements 14 and 14 'is not required. This is a very short and positive flow of force possible for the stroke.

Die Hauptwelle 19 ist gemäss Figur 1 mit einer Kreuzkupplung 60 mit einer Welle 61 verbunden, die drehfest in eine Habe 62 des Kurvenrades 17 des Schneidelementes 14 eingreift. Die Schneidelemente 14 und 14' werden somit gemeinsam angetrieben. Denkbar sind aber auch einzelne Antriebe.The main shaft 19 is according to Figure 1 with a cross clutch 60 is connected to a shaft 61 which rotatably fits into a holder 62 of the cam wheel 17 of the cutting element 14 engages. The Cutting elements 14 and 14 'are thus driven together. Conceivable are also individual drives.

Die Gegenmesser 5 sind jeweils an einem Träger 32, 33 gelagert. Diese Träger 32 können jeweils in den Richtungen des Doppelpfeiles 34 horizontal verschoben und dadurch exakt gegen die Schneidmesser 8 eingestellt werden. Dazu ist in den Träger 32 ein Langloch 50 eingearbeitet, in welches eine gestellfeste Achse 51 eingreift, wie die Figur 5 zeigt. Zudem sind die Träger 32 so am Gestell 31 befestigt, dass sie jeweils in Richtung des Pfeils 35 zusammen mit dem Gegenmesser 5 von der Schneide 9 weggeschwenkt werden können. Dadurch werden die Messer 8 für den Messerwechsel leicht zugänglich. Die Träger 32 decken zudem die Schnittstellen ab und schützen gegen eine Verletzung.The counter knives 5 are each mounted on a carrier 32, 33. These carriers 32 can each in the directions of Double arrow 34 moved horizontally and thereby exactly against the cutting knife 8 can be adjusted. This is in the Carrier 32 incorporated an elongated hole 50 into which a frame-fixed Axis 51 engages, as shown in Figure 5. In addition the carrier 32 are attached to the frame 31 so that they each in the direction of arrow 35 together with the counter knife 5 can be pivoted away from the cutting edge 9. Thereby the knives 8 are easily accessible for changing knives. Carriers 32 also cover and protect the interfaces against an injury.

Infolge der festen Anordnung der Gegenmesser 5 über den Produkten 41 hat die Dicke dieser Produkte 41 keinen Einfluss auf die Position der Oberbänder 12. Diese müssen somit nicht wie bisher zur Berücksichtigung der Dicke der Produkte 41 vertikal verstellbar sein. Der für die Unterbrechung des Transportes notwendige Hub der Oberbänder 12 kann deshalb vergleichsweise einfach ausgebildet sein. Vorrichtungen zur Ausübung des Oberbänderhubes, sowie geeignete Bandantriebe und Steuerungen sind dem Fachmann bekannt und werden deshalb hier nicht näher erläutert.Due to the fixed arrangement of the counter knives 5 above the products 41 the thickness of these products 41 has no influence to the position of the upper belts 12. These do not have to as before to take into account the thickness of the products 41 be vertically adjustable. The one for the interruption of the Transport necessary stroke of the upper belts 12 can therefore be comparatively simple. Devices for Exercise of the upper belt stroke, as well as suitable belt drives and controls are known to the person skilled in the art and are therefore not explained in detail here.

Zur Anpassung an die Dicke der Produkte 41 sind die Unterbänder 11 an einer hier nicht gezeigten Vorrichtung so gelagert, dass sie in Richtung des Doppelpfeils 47 (Figur 4) vertikal verstellbar sind. Solche Verstellvorrichtungen sind dem Fachmann an sich bekannt und werden deshalb hier nicht näher erläutert. Die Trennung dieser Verstellbarkeit vom Oberhub der Oberbänder 12 bedeutet jedoch eine wesentliche konstruktive Vereinfachung. Bisher mussten beide Funktionen in die Oberbänder 12 integriert werden.The lower belts are to adapt to the thickness of the products 41 11 mounted on a device not shown here, that they are vertical in the direction of the double arrow 47 (Figure 4) are adjustable. Such adjustment devices are Those skilled in the art are known per se and are therefore not described in more detail here explained. The separation of this adjustability from the upper stroke the top bands 12, however, means an essential constructive Simplification. So far, both functions had to be in the Upper bands 12 are integrated.

Die Schneidmesser 8 sind jeweils auswechselbar mittels einer Befestigungsschraube 52 am Träger 15 angebracht. Wie die Figur 5 zeigt, greift die Befestigungsschraube 52 in eine Gewindebohrung 53 des Schneidmessers 8 ein und ist an ihrem Kopf an einer Platte 54 abgestützt. Zum Auswechseln des Schneidmessers 8 wird der Träger 32 in die in Figur 5 gezeigte Stellung weggeschwenkt und die Befestigungsschraube 52 soweit aus der Gewindebohrung 53 herausgedreht bis das Schneidmesser 8 vom Messerträger 15 abgehoben werden kann. Entsprechend kann ein neues Schneidmesser 8 in einfacher Weise mit der Schraube 52 am Träger 32 befestigt werden. Der Träger 32 weist zudem einen Absaugkanal 55 auf, der sich entlang des Schneidmessers 8 erstreckt und an eine hier nicht gezeigte Absaugvorrichtung angeschlossen ist. Zur Abdichtung des Kanals 55 ist eine Platte 56 am Lagergehäuse 30 angebracht. Ist der Träger 32 mit einer Spannungsschraube 57 gemäss Figur 2 am Lagergehäuse 30 befestigt, so gelangen bei jedem Schnitt die hier nicht gezeigten Abschnitte in den Kanal 55 und werden in diesem wegtransportiert.The cutting blades 8 are each interchangeable by means of a Fastening screw 52 attached to the carrier 15. Like the figure 5 shows, the fastening screw 52 engages in a threaded bore 53 of the cutting knife 8 and is on her Head supported on a plate 54. To replace the Cutting knife 8, the carrier 32 in that shown in Figure 5 Position swung away and the fastening screw 52 as far screwed out of the threaded bore 53 until the cutting knife 8 can be lifted from the knife carrier 15. Corresponding can use a new cutting knife 8 in a simple manner the screw 52 are attached to the carrier 32. The carrier 32 also has a suction channel 55 which extends along the Cutting knife 8 extends and to a not shown here Suction device is connected. To seal the channel 55, a plate 56 is attached to the bearing housing 30. Is the carrier 32 with a tension screw 57 according to FIG. 2 attached to the bearing housing 30 so arrive at each cut the sections not shown here in the channel 55 and transported away in this.
