TwinDrive double unwind
Boost your winding capacity through faster jumbo roll change
The new TwinDrive double unwind ensures a winding capacity that is up to 20 percent higher compared to the use of conventional unwinding systems. This advantage is achieved through the additional unwind position and fully-automated jumbo roll changes. With conventional systems, the winding capacity is limited due to downtimes during jumbo roll changes. The fully-automated process of TwinDrive eliminates these downtimes, resulting in a significant increase in both efficiency and productivity.
Depending on customer requirements, the paper web is connected automatically with a FlyingSplice or ButtSplice. The significant time savings result in higher production rates. Depending on production conditions, considerably more jumbo rolls can be processed by the winder.
Your benefits with TwinDrive
- 20% higher winding capacity
- Efficient broke handling
- Operator-friendly control concept
- Short installation and start-up time
- Safety through fully-automated process
- Maintenance-friendly due to good accessibility
