Hunkeler Roll to Roll equipment

The Unwinder UW6 and the Rewinder RW6.

 The dynamic unwind module from the latest POPP6 series is especially suitable for flexible, high-performance use. Easy handling, thanks to automated loop control and user guide with touch-panel, reduces setup time to a minimum. Rolls with diameters of up to 1370 mm can be loaded semi-automatically. A triple loop control guarantees optimal and precisely tensioned winding of the paper web and helps with the processing of light as well as heavy paper weights. The loop weight is fully decoupled during neutral mode, thus guaranteeing optimal feed, also on high-performance digital printers.

 Rewind module RW6: Rewinding of a printed continuous web, for finishing in inserting, bursting and cutting installations. The high-performance rewind module from the POPP6 generation works process-safe up to speeds of 220 m/min. Constant web tension plus the proven centre-driven system help with precisely tensioned rewinding of the roll for light and heavy grammages. The optional center-cut unit enables longitudinal cutting of the web parallel to rewinding
