Daco DF350SR Semi-Rotary Die Cutter

  • Daco DF350SR semi-rotary die cutter.

The Daco DF350SR is a compact versatile semi-rotary die cutter / converting line for labels, semi-rotary for short runs and full rotary for high speed longer runs. 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 DF350SR 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 DF350SR has a 600mm (23.6”) unwind and rewind with automatic taper tension control ensuring that roll changes are kept to a minimum.

The flexibility of the DF350SR platform enables a converting line to be configured for most digital finishing applications:-

Full servo mode:

Standard flood coating

Die cut in register to a pre-printed web

Optional: Spot varnish

With the servo print / coating station turned off:-

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

Slitting and rewinding

Plain label production – full or semi-rotary

Standard Features of the Daco DF350SR Semi-Rotary Die Cutter
