During the use of the slitter, its tension will change. So what is the reason for the tension change of the slitter? The following slitting machine manufacturers share the factors of tension changes.
        1. During the rewinding and unwinding process of the slitting machine, the diameter of the rewinding and unwinding is constantly changing. The change in diameter will inevitably cause the change of the tension of the raw material. Unwinding under the condition of constant braking torque, the diameter will decrease and the tension will increase accordingly. Rewinding is the opposite. If the rewinding torque is constant, the tension will decrease as the rewinding diameter increases. This is the main factor that causes the tension of raw materials to change during operation;
        2. The change of the lifting speed of the machine will inevitably cause the change of the tension of the whole machine:
        3. Non-uniformity of slitting raw materials. For example, the fluctuation of the material elasticity, the thickness change of the material along the width and length, the eccentric mass of the roll, and the changes in the temperature and humidity of the production environment will also affect the tension fluctuation of the machine;
        4. The change in the tightness of the raw material coil will also cause the change of the tension of the whole machine;
        5. The change in speed during slitting affects the change in tension: when the speed is increased or decreased during operation, the speed of the main motor changes. First, the tension of the material in the unwinding traction to the winding section is caused to change momentarily, and the material must be slightly vibrated after a period of time to gradually stabilize the tension. The instability of this tension is manifested by the uneven winding on the finished roll and the unevenness on the end surface, which affects the product quality.
        6. The transmission mechanism of the slitting machine (such as guide roller, floating roller, flattening roller, etc.) has factors such as imbalance and unstable air pressure.

        After reading the above content, I believe that everyone already knows the factors that change the tension of the slitting machine.
