Jumbo Roll Un- and Up-Winders

Durst has developed, together with its partners, special un- and upwinders for Jumbo rolls up to roll diameters of 110 cm (43 inches) and up to 750 kg (per roll) to be used in conjunction with the roll to roll inkjet-printers Rho 160R/Rho350/351R and Rho 320R. As to customer's wish systems are available for one or two rolls. Three of these winding units have been delivered and are satisfactorily in use for months in The Netherlands (wallpaper printing) and Germany (polyester film printing).

The winding and unwinding speed can be adjusted accordingly to the printing modes of the Rho between 0,9-1,6 m/min (35.3-62.8 inches/min); they guarantee a telescope-free winding , have 76 mm (approx three inches) pneumatic steel cores and a walkway between winder/unwinder and printing unit for inspection. The winders/unwinders are separately supplied with electricity, their sensoric system (tension control, stop etc.) is coupled to that of the Rho whose software is adapted for this function.

The Jumbo roll device allows continuous, unattended printing for six to eight hours in an industrial environment.
