MODELLO BREVETTATO

Surf Model

New SURF model, last in the line in the range of friction rings, makes IES Differential Rewinding Shafts easier to use than ever.

Thanks to their innovative design and special technical features (Patent Pending), SURF rings simplify the operator’s daily work, REDUCING DOWNTIME, CYCLE TIME AND MACHINE COST.

Loading and unloading operations are much faster, now!

The wound reels can be removed from the shaft without manual operations, without reverse shaft rotation, and without damaging the internal surface of the core.

New SURF friction rings are the only UNIVERSAL rings that can be used on all dual and turret slitter rewinding machines.
