JC1650 Jumbo Companion unwinder for mother rolls up to 100 cm in 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 mother rolls with a diameter of up to 100 cm and a weight of up to 500 kg, in addition to the internal unwinding of these machines. The material is fed into the rewinding machine under the usual web tension control and is then available there for the series production of short rolls and narrow rolls. At the same time, conventional internal unwinding can still be used on Nepata rewinders and slitters.
Mother rolls are set up on the JC1650 using through-shaft tension shafts with a diameter of 3″ or 6″; the roll with the tensioned shaft is then placed and locked into the jumbo unwinder via folding bearing blocks. The film web is fed into the Nepata rewinding 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. The JC1650 can process a wide range of different media – similar to Nepata rewinding machines.
