How to slit narrow and hard material?

For narrow and hard materials, such as bimetallic coil, it is impossible to use bonded stripper rings, because the thickness of the bonded stripper ring is less than 4 mm, and the rubber part is easy to fall off. For hard materials, bonded stripper ring is not able to push them out successfully, so a steel stripper ring is needed to press material during slitting. The outer diameter of this steel ring is much larger than that of the round knife, and the width is slightly narrower than that of the material stripper. The inner hole is sleeved on the outside of the spacer ring. The positioning of the outer circle mainly depends on three points: one point is the lower part of its outer circle, which is directly pressed against on the surface of the strip, the other two points are the two thin shafts above the upper shaft and below the lower shaft. When the slitting machine starts cutting and the upper and lower shafts start to rotate, the steel stripper ring rotates within the range of three points. Because its center deviates from the axis of the upper and lower shafts of the slitting machine, it is called an eccentric ring. The position of the two thin shafts can be moved up and down (or left and right), thereby pressing the eccentric ring, so that it has a small amount of ring deformation, thereby pressing the material strip. It is this force that drives the eccentric ring to rotate.
