United paper Industries (UPI), reports that a rewinder rebuild by A.Celli, Italy, at its mill in Kuwait has been very successful. Initially, the project involved replacing the old slitting unit and updating the tension control system. In a subsequent phase, the intervention was extended with the addition of a new unwinder with brake and load cell system.

This newly defined project, which got underway at the beginning of this year and was shipped in April, produced great results in terms of production performance, the mill said. Due to the close collaboration and synergies in experience created between the A.Celli team and UPI technicians, the new slitting unit was operational by July. Startup was fast and easy, with just a little more than 30 hours (34) of stoppage of the unwinder—the very minimum amount needed for such a critical replacement.

"The advantages of the rebuild are clearly evident. Thanks to the new brake system with load cells, winding quality is uniform and the roll is more compact than before; the cut is very accurate, and the rewinder’s speed has increased by 20%. We are totally satisfied with the job done," UPI stated.
