Daco DF330R Digital Converting and Finishing System

Daco DF350R digital finishing

The Daco DF330R is a compact versatile converting line for labels. The machine is available for flexographic printing applications or for the converting of media from pre-printed digital, inkjet, flexo and gravure printing presses.

Easily apply spot or flood coat UV varnishes, the DF330R can also be configured with an optional laminating station to give ultimate flexibility for digital finishing applications.

The flexographic print / coating station 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 very little substrate.

Even with the machines compact size the DF330R has a 700mm (27.5”) unwind, with closed loop tension control, and rewind with automatic tension control ensuring that roll changes are kept to a minimum. A smaller optional rewind is also available for digital converting and plain label / slitter rewinding functions.

The flexibility of the DF330R platform enables a converting line to be configured for most applications:-

Full servo mode:

Print & die cut to register – Print & die cut in register to a pre-printed web, for example spot varnishing.

Print to print – 2nd pass facility or additional print station

With the servo print / coating station turned off:-

Die cut to register – Die cut to register pre-print webs

  • Web width 330mm (13″)

Standard Features of the Daco DF330R Digital Converting and Finishing System

  • Unwind
    • Maximum unwind diameter: 700mm (27.5″)
    • 76mm (3″) diameter air shaft
    • Merobel electromagnetic particle brake
    • Closed loop tension control
    • End of roll function – The user is able to 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.
  • Electronic Web guide
    • Ultrasonic sensor – enables guiding of opaque and clear materials.
    • Adjustable web guide sensor.
    • +/- 25mm (1″) correction.
    • Integral splice table with pneumatic interlocked web clamps.
  • Flexographic print / coating unit

    • The silicone nip roller does not allow labels to attach themselves to it reducing down time.
    • Fully adjustable via a regulator and gauge.
    • On / off feature to allow for easy webbing up of the machine.
    • Interlocked so that the machine can not be started with the nip roller off.
    • The draw roller is driven by a 1.5Kw (2 hp) motor to isolate the unwind tension from the rewind.
  • Slitting
    • 3 rotary scissor slitting knives (shear knife).
    • Knife separation – Allows for easy setting of the knife and anvil with the web in place.
    • Minimum slit width: 13mm (0.51″)
    • Lateral knife adjustment: +/- 5mm (0.196″)
  • Product Rewind
    • 1 Product rewind
    • Max rewind diameter: 700mm (27.5″)
    • 76mm (3″) diameter air shaft
    • Automatic taper tension control
    • Merobel electromagnetic particle clutch
    • The rewind is driven by a 1.5Kw (2 hp) motor.
  • Count Facility
