Filter Paper Roll Slitter


The slitting section has three main options:


Razor slitting, which is ideal for thin plastic films - the system is very simple and quick to set. Although the razor blades are of low cost, they need to be frequently changed to ensure a good quality slit edge.

Rotary shear slitting. Male and female circular knives engage to give a scissor cutting effect. This system is used widely on paper, films and foils. Although the knives take longer to position, they stay sharp longer than razor blades. The setting time can be reduced by using an automatic knife-positioning system.

Crush cut slitting. A male knife runs against an anvil. The system works well with certain materials including non-wovens and foams.

The rewind section also has options. The main type is centre winding using differential rewind shafts. These shafts are becoming universal on most slitting machines. The differential shafts ensure an even tension across the full width of the material. Closed-loop control of the winding tension using feedback from load cells provides the total tension-control system required for running tension-sensitive materials. Precise and accurate tension control is the key to good roll slitting. Modern machines use AC vector drives with closed-loop feedback from AC motors. When used with the correct control algorithms, they produce excellent results with the minimum of maintenance.
