Note(s)

  1. This subclass covers:
    • perforating, punching, cutting-out, stamping-out;
    • severing, by means other than cutting, non-metallic sheet material or metal foil in general;
    • severing, by means other than cutting, other forms of non-metallic materials not otherwise provided for.
  2. Attention is drawn to Notes (1) and (2) following the title of subclass B26D.
