Machine infrastructure performance, so to reflect its technical performance must know the principles. As a resistance device, the magnetic powder clutch of the cutting machine controls the resistance of the magnetic powder clutch through system control and DC voltage output. The main advantage of passive components is that they can control less tension. Cutting machine cooperates with other paper machinery products to maximize performance. For example, paper cutter, rewinder and tissue paper machine cut into rolls and tissues according to the required length, width. Band saw cutting table equipped with automatic grinding knife, movable, stable performance, high production efficiency. Band sawing is a well-known product quality improvement designed to reduce toilet paper, flat tissue dedicated equipment.
