Description

  

   <Desc/Clms Page number 1> 
 



   Die Erfindung bezieht sich auf eine Schneidvorrichtung zum Abscheren bzw. Abschälen einer Materialbahn.
Die Erfindung wird an Hand der Zeichnung durch ein Ausführungsbeispiel näher erläutert, das schematisch und schaubildlich eine Schneidvorrichtung zum Abscheren bzw. Abschälen einer Materialbahn zeigt. 



   Mit Hilfe einer Schneidklinge--3--, welche aus magnetisierbarem Material besteht und von einem unter 
 EMI1.1 
 magnetischer Anziehung nicht über ein vorbestimmtes Mass hinaus in die   Materialbahn --1-- eindringt.   Auf diese Weise lässt sich sodann von der Materialbahn-l-eine   Folie-6-konstanter   Stärke abschälen. 



   In dem dargestellten   Ausführungsbeispiel   weist die Schneidklinge--3--die Gestalt eines flachen Blattes auf. Die Schneidklinge kann vielmehr auch ein prismatischer Körper sein. 



   Wenn in der Beschreibung von magnetischen Arbeitsteilen die Rede ist, so ist darunter ein Arbeitsteil zu verstehen, welcher aus Permanent- oder Elektromagneten besteht bzw. solche enthält. Ferner ist ein magnetisierbares Material ein ferromagnetisches Material, welches seinen magnetischen Zustand von einem magnetisierenden Magneten erhält, u. zw. vorzugsweise vorübergehend, solange der magnetisierende Magnet anwesend ist bzw. wirksam ist.

   The invention relates to a cutting device for shearing off or peeling off a material web.
The invention is explained in more detail with reference to the drawing by means of an exemplary embodiment which schematically and graphically shows a cutting device for shearing or peeling off a material web.



   With the help of a cutting blade - 3 -, which consists of magnetizable material and one under
 EMI1.1
 magnetic attraction does not penetrate beyond a predetermined amount into the web of material --1--. In this way, a film 6 of constant thickness can then be peeled off from the material web 1.



   In the illustrated embodiment, the cutting blade - 3 - has the shape of a flat sheet. Rather, the cutting blade can also be a prismatic body.



   When magnetic working parts are mentioned in the description, this is understood to mean a working part which consists of or contains permanent magnets or electromagnets. Furthermore, a magnetizable material is a ferromagnetic material which receives its magnetic state from a magnetizing magnet, and the like. between. Preferably temporarily, as long as the magnetizing magnet is present or effective.
