In the papermaking industry, the circular knife, often referred to as a round cutter or rotary knife, is a precision cutting tool used for trimming and cutting paper or paper products. It features a sharp, circular blade that rotates at high speeds, allowing for clean and efficient cuts. These knives are typically made from durable materials like high-speed steel or carbide to withstand wear.

Function:
- Trimming: Circular knives are primarily used to trim the edges of paper sheets, ensuring they have uniform dimensions and a clean finish.
- Cutting: They are also employed for cutting larger rolls of paper into smaller sheets or sections, facilitating easier handling and processing.
- Efficiency: The rotary action of the circular knife allows for continuous cutting, making it ideal for high-speed production environments where speed and precision are crucial.
- Reduced Waste: By providing clean cuts, circular knives help minimize paper waste during the cutting process, enhancing overall efficiency.

In summary, the circular knife is essential in the papermaking industry for its role in trimming and cutting paper products efficiently and precisely.
