JC1650 JUMBO COMPANION UNWINDER FOR NUT ROLLS UP TO 100 CM DIAMETER

The Jumbo Companion JC1650 can be operated on a UA1650 ADWS converting center or on a UA1650 rewinding machine to unwind jumbo rolls or parent rolls up to 100 cm in diameter and weighing up to 500 kg in addition to the internal unwinding of these machines. The material is thereby drawn into the rewinding machine under the usual web tension control and is available there for the series production of short rolls and narrow rolls. In parallel, however, conventional internal unwinding can still be used on the Nepata rewinders and cut-offs.
The setup of the parent rolls on the JC1650 is done by means of push-through tensioning shafts in 3″ or 6″ diameter, the roll with tensioned shaft is then inserted into the jumbo unwinder via hinged bearings and locked. The film web is fed to the Nepata wrapping machine from the rear. Due to the smart web control of the JC1650, the inserted material is only touched and deflected at the bottom side, but not at its top side. A variety of different media can be processed in the JC1650 – similar to the Nepata rewinders.
