Schneid- und Transportwalze mit integrierter Schneidvorrichtung mit schwenkbaren Schneidflächen und Verfahren zum Schneiden von Materialbahnen mithilfe einer solchen Walze

摘要

The cutting device has at least one swivel fitted blade (9) guided by a blade holder. The swivel connection defines a rotational axis which is either parallel or at an acute angle to a perpendicular to the plane which is spanned by the radial and axial (r, z) co-ordinates of the roller. At least one blade is attached to a cutter bar (8) to carry out translation movement in the radial and/or axial direction of the roller. Independent claim describes method for cutting material webs where cutting movement executed by cutting faces of the at least one blade has rotational components.
