For embossing of box folding lines high precision creasing rules are required.
Folding box design and the precision of final products are becoming more
demanding, which requires the application of high quality creasing rules with
Creasing rule tolerances have to be adjusted to the tolerances of cutting
rules. This is of paramount importance for best creasing results. Bohlerstrip
creasing rules offer:
– Very smooth crease head surface
– Perfectly radiused profile
– Smooth transition from radiused profile to the side faces
– Minimum excentricity
– Minimum height and thickness tolerances
Bohlerstrip creasing rules are produced in two manufacturing methods,
depending on the rule thickness:
HT – Hardened and Tempered:
This process guarantees stability on creasing rules with thickness ≤ 3 pt.
HR – Hard Rolled:
This type of creasing rule is recommended for rule ≥ 4 pt.
