Daco D250 / D350 / D430 Rotary Die Cutter
D250 / D350 / D430 rotary die cutter is a compact rotary die cutting machine to produce plain labels for the small to medium production runs. The machine has an host of options to enable a converting line to be configured for most applications. The machine is available with a 250mm (10″), 350mm (13.75″) or 430mm (17″) web width, a speed of 175 m/minute (575 ft/minute) and a 700mm (27″) unwind.
Benefits
The Daco D250 / D350 / D430 rotary die cutter for the production of blank / plain labels is aimed at the medium to long production runs. It utilises either a single or dual rotary die cutting station. The large 700mm (27.5″) unwind with taper tension control and Merobel electronic brake keeps roll changes to a minimum.
The machines compact size and short web path keep wastage to a minimum, the fully adjustable silicone covered nip drive roller helps to keep downtime to a minimum as labels cannot attach themselves to the roller. The D250 / D350 / D430 rotary die cutter has accurate tension control through the use of an electronic unwind brake with taper tension control, and the rewind is controlled through a servo-driven rewind. 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 quick and straightforward. 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.
With the optional upgrade to servo drive, clients can die-cut material from digitally printed webs.
- Web width 250mm (10″), 350mm (13.75″) or 430mm (17″)
Standard Features
Unwind
- Maximum unwind diameter: 700mm (27.5″)
- 76mm (3″) diameter air shaft
- Merobel electromagnetic particle brake
- Automatic taper tension control
- 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.
