CITO PLAST Reverse Crease
The perfect solution for premium reverse crease how it is often used for inline cutting of corrugated board. Example: cutting from the reverse side of Leporellos.
Due to the specially developed transfer profile for variable distances of creasing rules the correct creasing parameters can be used. Result: Crease and reverse crease in convincing top quality.
The special locator centers the reverse crease exactly between the creasing rules, thus the crease and reverse crease are of the same quality.
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)
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 *
* in the case of corrugated board = compressed material thickness
h = creasing rule height top
