Slitter Cutting Control Parameters

There are basically three slitter cutting control parameters for the shear cut method, which uses the same principle as scissors.

1. Contact Pressure
2. Toe-In
3. Overlap Value
  1. Contact Pressure – the pressure that occurs when the upper knife and lower knife exert force on each other.
Contact Pressure 1.0N (edge of roll at 100x)
Contact Pressure 0.3N
  1. Toe-In – viewed from the top and forward direction of the knife. The slight forward tilt as shown in the figure is called toe-it. This is shown as an angle, but this is too small to express as an angle and is expressed as a force.
Toe-In angle 1.0N
Toe-In angle 0.3N
  1. Overlap Value – this is the depth of the upper and lower knives.

These three factors can be controlled manually or automatically.

Maysun Corporation was established based on a Paper-making company in 1967. So we see from perspective of Paper-making manufacturers and have developed technology which they require truly.
We are pioneers in the introduction of numerical control to Paper-making machine, and rated highly by our customers.

And other than paper-making, orders of NC Slitters and Non-contact thickness gauges for optical films for Flat Panel Display and electrode materials of lithium-ion battery are increasing in number. Our products rated highly by trendsetter material manufacturers.
