Introduction To Tension Control

This control must be effective for any speed of the machine, including acceleration, deceleration and constant speed of the machine. Even in the case of an emergency stop, there should be the ability to ensure that the cuts are not damaged. The stability of tension control is directly related to the quality of the slitting product. If the tension is insufficient, the raw material will drift during operation, and the finished paper will wrinkle after slitting and rewinding; if the tension is too large, the raw material will be easily broken, so that the finished paper breaks after slitting and rewinding.

The main function of the tension controller: to achieve constant tension control of the coil, or to achieve taper control of the coil tension according to the process requirements. Under normal circumstances, there are many occasions requiring constant tension control; for taper control, it is generally applied in the case of winding, such as achieving tight inner ring of the coil and loose outer ring, so that the material is not easily deformed after being rolled up.

The most widely used brands in China are: KORTIS, Mitsubishi, etc. 

Many of Mitsubishi's domestic agents are more expensive; KORTIS has relatively stable performance and high cost performance, and it is widely used in China.
