The application range of upper and lower slitting circular knives is extremely broad, covering nearly all industries that require the longitudinal slitting of wide rolls into narrow strips. This tool employs a shearing method using two circular blades—one upper and one lower—to achieve efficient and precise cutting.
The specific applications can be summarized into the following main areas, illustrated by typical materials:
Paper Product Processing: Various types of paper and paperboard, such as cigarette paper, tray paper, cable paper, capacitor paper, and newsprint.
Films and Tapes: Optical films, release films, protective films, stretch films, adhesive tapes, self-adhesive labels, etc.
Metal Foils: Aluminum foil, copper foil, gold foil, silver foil, as well as electrode sheets for lithium battery cells.
Textiles and Nonwovens: Nonwoven fabrics, woven textiles, carpets, etc.
Rubber and Plastics: Rubber sheets, plastic sheets, foam materials, leather, etc.
Specialty Materials: Specific materials used in industries such as magnetic tape, food, tobacco, and pharmaceuticals.
The widespread use of this cutting tool is attributed to several key advantages:
High Cut Quality: The unique shearing action reduces cutting resistance, resulting in a smooth, burr-free cut edge.
Durable and High Precision: The blades are typically made from high-hardness alloy steel, combined with precision machining and heat treatment processes, offering excellent wear resistance and long service life.
High Efficiency: Well-suited for continuous, automated production lines where high efficiency is essential.
