Unwinding solutions

Integrated unwinder : The integrated unwinding station is an independent module fixed on the main machine frame. It is constituted of two side plates assembled with a connecting cross bar and fitted with two safety bearings to receive the unwinding shaft. An electrical jack moves lalerally this module to insure material guiding.

Separated unwinder for larger mother roll diameter : The separate unwinding station is an independent module connected to the main machine frame through a walk-on bridge. It is constituted of two side plates assembled with a connecting cross bar fitted with two safety bearings to receive the unwinding shaft. The unwinding shaft could be cantilevered in order to ease loading operations. The unwinding shafts are driven through AC servo-motors, and their speed is automatically adjusted when diameter decreases. Also available as forck type for mother roll pick-up from floor.

Unwinding from A-frame/bock: The unwinding elements to unwind the material from existing A-frame/Bock constitute an independent module connected to the main machine frame through a walk-on bridge. A connectable brake is installed on the unwinding axle to the A-frame/bock to insure the material tension. A measuring cell or diameter feeler, allows automatic adjustment of the braking torque when the roll diameter decreases
