Daco DF250SRD Semi-Rotary Die Cutter

The Daco DF250SRD is a very compact modular semi-rotary die cutter. Finish labels from digital presses, add an inkjet system to print and finish in one pass or manufacture plain labels cost-effectively for desktop digital printers.

Benefits

The Daco DF250SRD is a compact, versatile semi-rotary die cutter / converting line for digital labels, semi-rotary for short runs and full rotary for high-speed, longer runs. The machine is the ideal companion to finish labels from digital presses, including inkjet and toner-based systems.

The Daco DF250SRD has seen a major upgrade to both its mechanics and software recently and now has an increased maximum production speed of 80m/min (262 ft/minute). This, coupled with the ability to easily remove the 22” magnetic die cylinder and replace it with our standard full rotary dies, allows the die-cutting of labels to a maximum speed of 175m/min (575 ft/minute) in register.

The DF250SRD utilises the latest in servo drive technology and, with software written by Daco, allows for quick and easy setup. With the environment and paper costs in mind, the print-to-die register is accomplished with the use of the minimal substrate.

The flexibility of the DF250SRD platform enables a converting line to be configured for most digital finishing applications. The platform also allows for fitting an inkjet module, allowing for labels to be printed and finished in one pass. As standard, the machine is prepared to accept laminating with or without a carrier, so if your requirements change in the future, laminating can be easily added.

The DF250SRD is the cost-effective solution to the finishing of digitally pre-printed webs from machines such as the Primera CX1200, Trojan T2, Afinia x350, i-Jet2800, Duraflex-based printers and other Memjet-based machines.

Standard Features

Web Width

  • Maximum web width: 250mm (10″)
  • Minimum web width: 101mm (4″)

Unwind

  • Maximum unwind diameter: 600mm (23.6″).
  • 76mm (3″) diameter air shaft.
  • Merobel electromagnetic particle brake.
  • End of roll function – The user can program the roll end diameter – slowdown and/or stop – The system does not use any roll followers or external sensors that can be damaged at roll changes. The diameter is programmed from the touch screen operator interface.
  • Web up – the operator can, at the touch of a button on the touch screen operator interface, release the unwind brake to allow for easier webbing up of the machine.
