Abstract:
A method of manufacturing a perforated sheet which has at least one hole. The method includes introducing at least two spaced boreholes into a sheet, the at least two spaced boreholes being formed so that they each pass through a thickness of the sheet, introducing a continuous cut between the at least two spaced boreholes in the sheet, and bending open a section of the sheet which is adjacent to the continuous cut so as to form a hole.
