Daco D250 / D350 Rotary Die Cutter

  • Daco D350 rotary die cutter

The Daco D250 / D350 blank / plain label converter is aimed at the medium to long production runs and utilises either a single or dual rotary die cutting station. The large 700mm (27.5″) unwind with taper tension control and electronic brake keeps roll changes to a minimum.

The machines compact size and short web path keeps wastage to a minimum, the fully adjustable silicone covered nip drive roller helps to keep down time to a minimum as labels cannot attach themselves to the roller. The D250 / D350 has accurate tension control through the use of an electronic unwind brake with taper tension control and the rewind is controlled through an electronic clutch. Quick set rotary slitting with on the run lateral adjustment is fitted as standard, the slitting knives can be set with the web in position unlike some cartridge systems. A splice table makes web splices both simple and quick. Quick change air mandrels for the product rewind ensures that cores a gripped firmly and a production speed of 175m/minute (575 feet/minute).

The machine is ideally suited to clients wish to produce plain labels for the growing thermal transfer label market.

  • Web width 250mm (10″) or 350mm (13.75″)
