The NEPATA JC1650 Jumbo Companion unwinder was developed to be operated with the UA1650 ADWS Converting Center or the UA1650 Rewinder to process jumbo rolls or master rolls with a diameter up to 40 inches or a weight up to 1,650 lbs. Positioned behind the UA1650 ADWS, the material is fed into the machine underneath the usual web tension control allowing for efficient production of short rolls from large jumbo master rolls.
