Abstract

The invention relates to a circular knife device (10) for cutting to size sheet-like materials, in particular paperboard and/or textile materials, in particular cover boards and/or covering materials, wherein the circular knife device (10) defines a cutting plane in which the sheet-like materials are arranged and are moved in a transport direction (14), having at least one circular knife (46) and an associated circular knife axis, wherein the circular knife (46) is rotatable about the circular knife axis, wherein the at least one circular knife (46) is movable parallel to the cutting plane and perpendicularly to the transport direction (14) with the result that a blank width of the sheet-like materials is settable in a variable manner, wherein the at least one circular knife (46) is mounted so as to be pivotable about a pivot axis (52) arranged substantially perpendicular to the cutting plane such that cuts at an angle to the transport direction (14) and curved cuts of the sheet-like materials are able to be executed.
