Design decisions

Converters should again look at a material's width, weight and roll diameter to determine the best winding equipment design: shafted, shaftless or cantilever.

"Shafted designs are most common for intermediate widths of 20à to 40à, but for wider widths the core shafts become too heavy to handle without special equipment," explains Plude. "A hoist or other lifting device is usually required to load the roll and shaft into the unwind.
