5.3 PERFORATIONS
5.3.1. Sheet edges at fold perforations
To avoid tearing, there must be a tie of width
≥
1 mm beginning at a distance of
≤
1 mm from sheet
edge.
5.3.2. Fold perforation tensile strength
For fanfold forms, fold perforation tensile strength must be between 800 and 2000 N/m.
For rolls, refer to specifications of pre- and post-processing equipment.
5.3.3. Fanfold beak set
- Hang a segment of 5 to 10 sheets vertically and check that all folding angles are identical.
- Hang a segment of 5 sheets against a vertical flat surface, with the top sheet touching the
surface and the first fold opening away from the surface. The distance between the lowest fold
and the vertical surface must be less than 30mm.
5.3.4. Internal Perforations
Tensile strength of internal vertical perforations must be at least 700N/m.
Tensile strength of horizontal perforations must be between 800 and 2000 N/m.
Authorized internal perforations for fanfold output
Horizontal perforations must be spaced more that 2 in. from fold perforations.
