Benefits
The Daco SVT350 / 430 modular servo-driven turret rewinder is a very flexible converting machine. The 4 spindle turret offers quick change over times, which coupled with a colour touch screen HMI operator interface makes the machine both interactive and user-friendly.
The operator can select from either length or a given number of labels per roll, and the machine will then automatically cut and transfer the web to the cores without stopping.
The Daco SVT utilises a unique double-sided tape system (patented) for attaching the web to the cores, and the finished rolls are closed using a label printed by an on-board thermal transfer printer. This eliminates the need for expensive and complicated hotmelt gluing systems which often cause problems for both machine operators and end-users. Job storage, coupled with an intuitive touchscreen control and minimal mechanical settings, makes the machine very simple to set up and operate.
A host of optional equipment enables you to specify a very adaptable converting line both now and in the future because of its modular construction.

Standard Features
Web width: 350mm (13.75”) or 430mm (16.92″)
Unwind
- Maximum unwind diameter: 700mm (27.5″)
- 76mm (3″) air mandrel
- Merobel electromagnetic particle brake
