A slitter device comprising:
- a disc body having
- a single circular blade at an outer periphery of the slitter device and
- at least one row of transverse blades at the outer periphery and on a side of the circular blade, the blades of the row of transverse blades being oriented transversely relative to the single circular blade.
A cutting die device comprising:
- a plate body configured to be positioned on a cylindrical surface and conform to a shape of the cylindrical surface;
- circumferential blade edges projecting from a plane of the plate body, the circumferential blade edges configured to extend along a circumference of the cylindrical surface;
