Unwind Rewind Module 6126

The UNWIND/REWIND modules modules have been designed for easy roll-to-roll materials process. The roll is unwound with a constant tension to keep it aligned before being rewound.
Advancement of the web is driven by servo-motors (drivers controlled) which manage speed, tension and diameter compensation.
The web alignment is controlled by two CCD sensors in the Y direction (one on the unwinding module and one in the rewinding module) and the tension is adjustable.
The roll replaced is locked and sealed by a couple of double splice table with pneumatic hold down bars.
The unwinding module is equipped with expansion rolls with independent servo-motor and with a special reinforced frame for holding the two heavy web rolls (250Kg each).
The rewinding module is also equipped with expansion rolls and independent servo-motors and with a special reinforced frame too.
