Two types of paper cutters can be used in the drying section of the paper machine (before gluing and before coiling) according to the parameters of the paper machine. When the paper locomotive speed exceeds 500m/min, it is recommended to use a paper guiding water knife, especially when entering the paper rope system, a high-quality, dust-free paper guiding strip is needed to achieve maximum reliability of paper guiding.

When the speed of the paper machine is below 500m/min, it is recommended to use a disc cutter (but never a fixed cutter, as it can tear and damage the narrow strip of the paper guide, causing paper breakage and paper guide trouble). Driven by a pneumatic motor and equipped with a stable cardboard, it can avoid the paper web from drifting during cutting. The paper web is stabilized by the principle of compressed air jet before cutting.

The paper cutter is mainly used as an emergency measure to prevent the paper from being squeezed by the cylinder and wrapped around the rollers during paper cutting in paper machines; When the system receives a paper breakage signal from the DCS system, the paper cutter will quickly cut the paper sheet; Or convert it into manual operation; This system is connected to the paper machine's paper breakage signal.
