Fully Automatic Drum Type Polyester Film Slitting Machine
High-Precision Slitting for Polyester Film Conversion
The Fully Automatic Drum Type Polyester Film Slitting Machine is designed for converting large diameter polyester films into small diameter reels, using precise cuts and reel formation. The polyester film is known for its stability, strength, and smoothness; however, proper handling is needed to retain these qualities during high-speed processing. The fully automated process allows for the coordination of unwinding, guiding, tensioning, slitting, and winding processes, ensuring proper movement of the material through each process step. The drum type winding system ensures constant support for the winding reels as the diameter increases. The machine can be used for plain PET film, printed polyester film, coated PET, metallized polyester, and laminate constructions.

Maintaining Polyester Film Stability During High-Speed Slitting
While polyester film has acceptable dimensional stability, changes in tension or web positioning can still impact cut quality even with continuous operation. The equipment keeps the film under controlled conditions moving from the master roll to the slitting station, where the web can stay properly aligned with the appropriate knives.
The automatic web control is beneficial especially when working with larger roll lengths as conditions will be changing throughout the unwinding process since the diameter of the roll will become smaller.
Through controlling the web tension, guiding, and cutting, the equipment helps maintain uniform widths of the reels while minimizing the formation of wrinkles or lateral movements.
Consistent Reel Density from Core to Final Diameter
Finished polyester reels need more than straight edges; their internal winding structure also affects performance during later processing. The drum-supported rewinding arrangement helps maintain controlled contact with the growing reels throughout winding.
Suitable winding conditions allow each film layer to settle progressively around the core, supporting consistent reel density from the beginning to the outer layers. This helps minimize telescoping, loose winding, excessive roll hardness, uneven sides, and irregular reel build-up.
Well-formed reels provide smoother unwinding when transferred to subsequent printing, coating, laminating, or other converting equipment.
Automatic Control for Longer Polyester Production Runs
Frequent manual adjustments will lead to delays in production if large polyester parent rolls are being processed. The all-automatic configuration is designed to ensure synchronized operating conditions after the proper production parameters have been set.
The operators will be able to configure the right slitting setup and the proper process conditions based on the thickness of the film, size of parent rolls, width of finished reels, and the need for winding. While the machine is running, the operator will monitor the condition of the finished reels and the overall operation of the machine. This configuration would be helpful for converters that repeatedly use PET films.
