Der Erfindung liegt die Aufgabe zugrunde, ein rotierendes Schneidmesser eines Falzapparates einer Rollenrotationsdruckmaschine zu schaffen.The invention is based on the object rotating cutter of a folder one To create web-fed rotary printing press.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. This object is achieved by the features of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß sich die Standzeit der Schneidmesser erhöht. Es können sowohl Schneidmesser zum Längsschneiden als auch zum Querschneiden von Papierbahnen oder -strängen mit der erfindungsgemäßen Beschichtung versehen werden.The advantages that can be achieved with the invention exist especially in that the life of the Cutting knife increased. Both cutting knives can be used Rip cutting as well as cross cutting of Paper webs or strands with the invention Coating.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention is in the Drawing shown and is closer below described.

In einem Falzapparat weist ein
Schneidmesser 1 z. B. für einen
Schneidmesserzylinder zum Querschneiden oder
Längsschneiden einer Papierbahn oder eines
Papierbahnstranges an seiner
dem Druckträger zugewandten Seite eine Schneidkante 4
auf. Zwei an der Schneidkante 4 beginnende
Schneidflächen 2; 3 verlaufen in einem öffnungswinkel
Alpha < 90°.
Die Schneidkante 4 kann durchgehend ausgebildet sein
oder nebeneinander angeordnete Zähne 6 aufweisen.In a folder, a cutting knife 1 z. B. for a cutting knife cylinder for cross cutting or longitudinal cutting of a paper web or a paper web strand on its side facing the printing medium on a cutting edge 4. Two cutting surfaces 2 beginning at the cutting edge 4; 3 run at an opening angle alpha <90 °.
The cutting edge 4 can be continuous or have teeth 6 arranged next to one another.
Das Schneidmesser 1 besteht aus Metall, z. B. bekanntem
Werkzeugstahl. Nur eine der beiden Schneidflächen 2 oder
3 ist von der Schneidkante 4 aus verlaufend über einen
Teil einer Breite oder über eine gesamte Breite a sowie
über die gesamte Länge mit Hartstoffüberzug 7 zwischen
0,5 µm und dicker, z. B. 15 µm, beschichtet. Es ist
bezüglich der Breite a des Hartstoffüberzuges 7 auch
möglich, daß der Hartstoffüberzug erst in der Nähe der
Schneidkante 4, d. h. ca. 0,5 mm von der Schneidkante 4
entfernt beginnt.The cutting knife 1 is made of metal, e.g. B. known
Tool steel. Only one of the two cutting surfaces 2 or
3 extends from the cutting edge 4 over a
Part of a width or over an entire width a as well
over the entire length with
Der Hartstoffüberzug 7 besteht aus einem Werkstoff aus
der Gruppe der Metallcarbide, -nitride, -oxide, -boride
der -silicide der Elemente der vierten bis sechsten
Nebengruppe des Periodensystems, einzeln oder in
Kombinationen verwendet. Dieser Hartstoffüberzug wird
z. B. mittels PVD-Beschichtungsverfahrens (physical
vapour deposition) aufgebracht. The
Eine Beschichtung mit den Substanzen 8 erfolgt in einer Dicke, die zwischen 0,5 und 10 µm liegt.The substances 8 are coated in one Thickness which is between 0.5 and 10 µm.
Während der Benutzung des so behandelten Schneidmessers 1 wird das Metall, z. B. der normale Werkzeugstahl infolge Verschleißes ausgearbeitet, so daß die nichtbeschichtete Schneidfläche 3 eine Aushöhlung 9 erhält, wodurch ein Selbstschärfeffekt des Schneidmessers 1 eintritt.While using the cutting knife treated in this way 1 the metal, e.g. B. the normal tool steel worked out as a result of wear, so that uncoated cutting surface 3 a cavity 9 receives a self-sharpening effect of the Cutting knife 1 enters.
Bei dem Einsetzen des Schneidmessers 1 in den
Schneidzylinder zum Querschneiden einer Papierbahn oder
-stranges ist darauf zu achten, daß stets die
nachlaufende Schneidfläche 2 des Schneidmessers 1 den
Hartstoffüberzug 7 bzw. die Substanz 8 aufweist, da die
vorlaufende Schneidfläche 3 eine "schabende" Bewegung in
der Schneidnut der Gegenschneidleiste 5 ausführt, welche
einen gewollten Verschleiß des Werkzeugstahls zur Folge
hat, der den Selbstschärfeffekt herbeiführt. Diese
"schabende" Bewegung des Schneidmessers 1 ist auf eine
höhere Umfangsgeschwindigkeit der Schneidkante 4
gegenüber der jeweiligen Umfangsgeschwindigkeit des
Schneidmesserzylinders sowie des Gegenschneidzylinder
zurückzuführen.When inserting the cutting knife 1 in the
Cutting cylinder for cross cutting a paper web or
-stranges must be ensured that the
trailing cutting surface 2 of the cutting knife 1 den
Nach einer anderen Ausführungsvariante kann auch analog
eine einseitige Beschichtung einer endlosen, d. h.
ringförmigen Schneidfläche eines Kreismessers mit dem
Hartstoffüberzug 7 oder der genannten Substanz 8 in
seinem Randbereich erfolgen. Solche Kreismesser werden
zum Längsschneiden von Papierbahnen verwendet. Beim
Einbau eines jeden Kreismessers ist darauf zu achten,
daß eine Sollverschleißseite jeweils z. B. mit einer
harten bzw. beschichteten Kante oder Fläche der
umlaufenden Schneidnut einer Nutwalze zusammenwirkt, um
eine Selbstschärfeffekt herbeizuführen. According to another embodiment variant, it can also be analog
a one-sided coating of an endless, d. H.
annular cutting surface of a circular knife with the
