Maschine und Verfahren zum Schneiden von ovalen Formgebilden

A machine is provided for cutting oval shapes in planar workpieces, wherein the blade is dynamically oriented so as to maintain its cutting axis constantly tangent to the line of cutting. It utilizes a pivotably mounted cutter head (178) to which is attached an orienting arm (230) that is arcuately...

More Information
Summary:A machine is provided for cutting oval shapes in planar workpieces, wherein the blade is dynamically oriented so as to maintain its cutting axis constantly tangent to the line of cutting. It utilizes a pivotably mounted cutter head (178) to which is attached an orienting arm (230) that is arcuately reciprocated by an element (124) moving unidirectionaally in a circle, the direction of circular movement being opposite to that in which the cutting head proceeds.
