In the process of winding and unwinding of the slitting machine, the winding and unwinding diameter is constantly changing, and the change of diameter will inevitably cause changes in the tension of raw materials.
When the braking torque is unchanged, the diameter of the slitter is reduced and the tension will increase. On the contrary, if the winding torque is unchanged, the tension will decrease as the winding diameter increases. This is the main factor that causes changes in the tension of the raw material during operation.
Changes in the tightness of the raw material roll also cause changes in the tension of the slitter. Inhomogeneity of the material of the slitting raw material. For example, the fluctuation of material elasticity, the change of material thickness along the width and length direction, the quality eccentricity of the coil, and the change of temperature and humidity in the production environment will also affect the tension fluctuation of the slitter.
If more detailed information or specific technical parameters are needed, further explanations can be made.
