We have modified the grind on some of our slitting blades – and have thus been able to significantly improve the final sharpness. The 240 mm x 2.0 mm and 297 mm x 2.5 mm blade types are now ground with a different geometry. The result is astonishing: we achieve greater final sharpness and much better cutting edges, without smearing or fraying. Our tests consistently showed a clean cut across all applications.

Cut rolls of black glossy film on the shaft of the cutting unit; clean cut edges without fraying thanks to the new blade grind
Rolls of yellow adhesive tape cut to length on cardboard cores, with clean, smooth cut edges and no fraying – the result of the new blade grind

For our machines fitted with a cutting-off unit – the UA1650 ADWS and 1900 ADWS – we offer a range of different blades for various applications; we’d be happy to advise you. We’d be happy to test your materials in our test studio. Please get in touch!
