Slitter rewinder machine is a machine to convert mother material rolls to narrower ones. Slitting effect of slitter rewinder is affected by many factors.
1. Unwinding tension control
Try to avoid changing the rewinding tension to ensure that the tightness of the material is uniform on the outside and inside. If the rewinding tension control of paper web is too small, the materials roll will loosen or slip on the bottom roller, forming wrinkles, interlacing of paper sheets and other problems. If the tension control is too large, it will cause damage to the paper core. Therefore, it is very necessary to control the tension during the rewinding operation of the adhesive paper web.
2. The linear pressure of the platen roller
As the diameter of the roll increases, the position of the pressing roller gradually rises, and the load provided by the pressing roller also gradually decreases. When the roll diameter reaches a certain value, the load provided by the platen roller is zero. At the moment, it only exists as a device to maintain the position of the paper roll. The pressure control program of the platen roller must be selected according to the paper quality and final diameter.
3. Speed difference between front and rear support rollers
The speed difference of the support roller
forms the rewinding force, which determines the tightness of the paper roll.
Increasing the rewinding force of the slitter rewinder can increase the
tightness of the paper roll.
