  Kegelförmiges Messer. 



   Die Erfindung betrifft kegelförmige   Rotationsmesser, sogenannte Tellermesser,   zum mechtanischen Schneiden   zylindrischen   oder ähnlich geformten Gutes und besteht darin, dass die Facette des Messers die Durchdringungskurve eines Kreis- oder beliebigen Kurvenkegels mit einem Zylinder bildet, dessen Achse im Falle eines Kreiskegels exzentrisch zu jener des Kegels liegen muss.

   Hiedurch wird die Facette bei   senkrechter Kegelachse verschieden   hohe Punkte aufweisen und das Gut, das dem um die Achse des Zylinders roliterenden Messer zugeführt wird. nach einer Zylinderfläche abgeschnitten, wobei die Facette je nach ihrer Krümmuing mit einem 
 EMI1.1 
 beliebiger Dicke mit ziehendem oder scherendem   Schnitt abzuschneiden, ohne dass wegen   der Kegelneigung die ganze Flache des Messers, vielmehr nur deren Facettenfläche mit dem Schnittgut in Berührung kommt, was selbst, hei   hohen Tourenzahlen die eintretende Reibungs-   wärme wesentlich herabsetzt und auch ein Zermalmen   von trockenem Fasermaterial vermeidet.   



  Überdies ist die Herstellung des vor der Aufwicklung durchaus eben gestalteten Messers wesentlich erleichtert. Das Messer kann   entweder aus einem Stück bestehen.   es kann aber auch als Zylindermantel auf einem Messerkopf oder als Facette tragender Messerstreifen auf einem der Messerform angepassten Messerkopf befestigt werden. 



   In der Zeichnung sind die drei letztgenannten   Ausführungsformen   mit verschieden gestalteten Messern beispielsweise dargestellt, u. zw. zeigt : Fig. 1 zwei zueinander senkrechte Schnitte eines einheitlich hergestellten, aus einem Kurvenkegel mit zentrisch liegendem Zylinder gebildeten Messers. Fig. 2 in gleicher Darstellung das aus einem Kreiskegel mit exzentrisch liegendem Zylinder gebildete Messer, das als Zylindermantel auf einem Messerkopf befestigt   ist.. und. Fig. 3 das   aus   einem     Kurvenkegel-und einem exzentrischen   Zylinder gebildete Messer, bei dem die Facette auf einem. Streifen angebracht und auf entsprechend geformtem Messerkopf befestigt, ist.

  Conical knife.



   The invention relates to conical rotary knives, so-called circular knives, for mechanically cutting cylindrical or similarly shaped goods and consists in the fact that the facet of the knife forms the penetration curve of a circular or any other curved cone with a cylinder whose axis, in the case of a circular cone, is eccentric to that of the cone must lie.

   As a result, the facet will have points of different heights when the cone axis is vertical and the material that is fed to the knife rolling around the axis of the cylinder. cut after a cylindrical surface, the facet depending on its curvature with a
 EMI1.1
 Any thickness can be cut with a pulling or shearing cut without the entire surface of the knife, rather only its facet surface, coming into contact with the cut material due to the taper inclination, which even at high speeds significantly reduces the frictional heat and also crushes dry Avoids fiber material.



  In addition, the production of the knife, which is completely flat before winding, is made much easier. The knife can either consist of one piece. but it can also be attached as a cylinder jacket on a cutter head or as a facet-bearing cutter strip on a cutter head adapted to the shape of the cutter.



   In the drawing, the last three embodiments are shown with differently designed knives, for example, u. between shows: FIG. 1 two mutually perpendicular sections of a uniformly manufactured knife formed from a curved cone with a centrally located cylinder. Fig. 2 in the same representation, the knife formed from a circular cone with an eccentrically lying cylinder, which is attached as a cylinder jacket on a knife head .. and. 3 shows the knife formed from a cam cone and an eccentric cylinder, in which the facet on a. Strips attached and attached to a correspondingly shaped cutter head is.
