Decoilers with two expandable mandrels

摘要

OTO SpA has unveiled decoilers that have an appropriate supporting structure capable of simultaneously handling two expandable mandrels that are counter positioned. Their main function is to support the coil during the unwinding phase, assuring a constant mechanical tension on the strip. The double mandrel solution is extremely convenient because it offers the possibility to put on the free mandrel a new strip coil (on loading side) while the other coil is being unwound to feed the line.
