The innovative solution for the perfect reverse crease (e.g. Leporello, cutting from the reverse side).
The special locator centres the reverse crease exactly between the creasing rules, thus the crease and reverse crease are of the same quality.

Legend
a = base height of reverse crease
b = total height of reverse crease
c = width of creasing profile
d = distance of creasing rules
e = width of reverse crease
f = cutting rule height (23.8 mm)
g = thickness of material*
h = creasing rule height
* in the case of corrugated board = compressed material thickness
|
|
Calculation of Reverse Crease
distance of creasing rules:
d = ( g x 1.5 ) + c (for solid board)
d = ( g x 2.0 ) + c (for corrugated board)
creasing rule height:
h = f - ( g + a )
We recommend using the creasing rules reversed in the cutting die.
