ROTARY CREASING RULES

For creasing the flaps of boxes 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
tight tolerances.
 

Creasing rule tolerances have to be adjusted to the tolerances of cutting rules.
This is essential 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
  




MANUFACTURING RULES 

bohlerstrip creasing rules are produced with different manufacturing methods,
depending on the rule thickness:


TOP 36
This execution is the standard for bohlerstrip rotary creasing.

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 rules ≥ 4 pt.

CREASING RULES - MARKING ON BOTH SIDES-

CREASING RULES - MARKING ON BOTH SIDES

FRONT SIDE

Standard ink-jet marking, 
very near to crease top: 

» bohlerstrip logo
» hammerman
» profile 
» height in mm/inch
» thickness in mm/pt 
» batch number 
» "Made in Austria" print

REAR SIDE - NEW

Continuous ink-jet printing, very near to crease top:

» height in mm/inch in bold letters and large front size

BENEFITS

» height control - to prevent crease insertion of wrong/different heights
» readability - height information still visible on short length pieces due to continuous print 
» height info fully visible even inside the plywood at converters
