High Speed Unwind-Rewind System

Product catalog summary
Overview: The High Speed Unwind-Rewind System is a fully automated solution designed for off-line surface treatment, particularly suitable for tubular film and sheeting applications. It is ideal for processes such as e-beam treatment of shrink films used in food packaging.
Key Features:
  • High-speed cutovers and fully automated operation with synchronized roll transfer sequences.
  • Innovative winding technology ensures high-quality rolls with zero scrap roll transfers.
  • Equipped with a degassing unit and a chill roll unit to remove trapped gases and cool the web post-treatment.
Applications:
  • Food packaging, specifically for enhancing shrinkability, puncture resistance, and stability through e-beam cross-linking.
System Components:
  • Automatic turret winder and rewinder with two spindles for continuous operation without interruptions.
  • Line software manages splicing and cutovers to minimize scrap by ensuring spliced areas are at the end of rewound rolls.

High Speed Unwind-Rewind System-1

Key Features: • High Speed cutovers • Fully automated operation with synchronized roll transfer sequences • Innovative winding technology produces high quality rolls with zero scrap roll transfers • Can be used for tubular film and sheeting Applications: • Food packaging - E-beam treatment of shrink films To achieve a final product with optimum properties it is often required to perform off-line treatment, such as e-beam cross linking to improve shrinkability, puncture resistance and stability. Macro's High Speed Unwind-Rewind System provides processors with an efficient means to perform these tasks by combining automation with advanced web handling technologies. The sytem features a fully automatic turret winder and fully automatic turret rewinder. Because they are both designed with two spindles, they can be operated continuously without interruptions caused by roll loading and unloading. Splicing of the unwinding rolls and winder cutovers are handled by the line software to ensure they are synchronized. This allows the system to minimize the amount of scrap generated as the spliced area is always left at the end of rewound rolls for easy removal. In addition to state-of-the-art winding and unwinding equipment, Macro's High Speed Unwind-Rewind System is also equipped with a degassing unit and a chill roll unit to remove trapped gases in tubular films and cool the web following treatment.
