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.
Claims8
A method of manufacturing a perforated sheet, the method comprising:
- introducing one pair of boreholes which are spaced apart from each other into a sheet, each borehole of the one pair of boreholes being formed with a round cross-section so that each of the one pair of boreholes pass through a thickness of the sheet;
- introducing a continuous cut between the one pair of boreholes in the sheet so as to form two sheet sections adjacent to the continuous cut;
- bending up at least one of the two sheet sections adjacent to the continuous cut so as to form a hole with a specific shape;
- introducing additional pairs of boreholes which are spaced apart from each other and a respective additional continuous cut between the additional pairs of boreholes at different positions of the sheet;
- and
- bending up at least one of the two sheet sections adjacent to the respective additional continuous cuts so as to form additional holes with the specific shape,
- wherein,
- each of the one pair of boreholes and the additional pairs of boreholes, and their respective continuous cut and additional continuous cuts, are arranged so as to be spaced apart from each other.
