Roll-to-Roll Gen8

The Hunkeler Generation 8 roll-to-roll solution features the latest high-speed unwinders and rewinders to ensure efficient downstream processing. The UW8 Unwinder and RW8 Rewinder can handle web widths of up to 22.5” and have been streamlined to reduce the time it takes to change rolls by up to 30% compared to the Generation 6 unwinder and rewinder.

  • At-a-glance updates: The system displays the time and paper remaining so operators can maximize efficiency.
  • Increased production speed and max roll weight: The system can run at up to 830 fpm and can handle rolls up to 1,980 lbs.
  • Easy alignment:: The core shaft has a groove at the zero position, making it easier for operators to align the core so the edge of the web corresponds with the zero position in the printers.
  • Lower arms:: The arms of the UW8 and RW8 reach lower than previous generations, so partial rolls can be delivered directly onto the cart (11.5” minimum OD) or to the floor (12” minimum OD).
  • Optional add-ons: The RW8 Rewinder can be equipped with one or more slitters and an edge trimmer on the left and right, with no limitations on processing speed or paper weight.
