The entire machine features pneumatic shafts with automatic inflation and deflation functions. It is additionally equipped with a film leveling mechanism to ensure the slit film remains flat without misalignment or rough edges. Multiple pneumatic components are used throughout the equipment to enhance control stability. The machine is simple to operate, saving time and effort, and supports four-shaft nonstop roll changes. The rewinding diameter can reach up to 260mm, achieving a qualitative breakthrough that makes it a true powerhouse among slitting machines. It is compatible with paper cores, plastic tubes, and injection-molded plastic cores.
