First, aluminum foil active slitting

That is, the round blade is rotated by the foil material, which is the same way as the razor blade, except that there are more cutting edges in contact with the material. In this way, since the blade itself is passive, it is affected by the speed of the material, and the contact point and the knife edge are pressed. The material winding is bounced. Because the blade itself has no power, the fluctuation of the winding is easy to warp.

Second, the circular knife active cutting

This is the most versatile way at the moment. There are two types of circular cutter active slitting, one is coaxial rotation and the other is single-arm motor drive. The one-arm drive is more suitable, which adjusts the blade speed depending on the thickness of the material. In the normal case of the round knife, the lower knife is matched with the slitting, and we usually see the butterfly-shaped upper knife.

Why do we use the butterfly-shaped upper knife? This is from Japan and South Korea. Because the parallelism is not enough, the butterfly blade can make up for this deficiency. We usually put the butterfly knife on the lower knife, which means that the parallelism is not enough. A good product. Because the thinner the blade, the parallelism tolerance is more difficult to control. However, the thicker the thickness, the greater the resistance, and the more prone to curling, indentation, and falling powder. Individuals, prefer thin blades, think that the thinner the blade, the better the cut product will be.
