Slitting machine, slitting machine looper (pit cause analysis) in the strip of varying lengths
The tension of the tension mechanism is uneven, and the tension of the tension mechanism is big. Small matters determine the tightness of the take-up volume, and the outer diameter of the take-up strip with a large tension is smaller, otherwise it is large. The take-up speed of the coil with big outer diameter is larger.
Relatively thin thickness of the strip, less winding diameter, winding speed is relatively small. This resulted in different lengths of strip pit the phenomenon.
The thickness of the raw material is uneven. Thick plate with a greater need of rolling force, rolling diameter leads to more and more big, the angular velocity of the same situation, the rolling line speed is faster, stay in the pit less material.
