Contact pressure between the package and the drum is controlled accurately through precise
setting on the Visual On-demand System(VOS).
At the start of winding, the package is pressed with optimum pressure against the drum so as to
prevent slippage, drum rotation can reach a top winding speed immediately. This Quick Start
reduces the acceleration time drastically and enables high productivity from the beginning of the
winding.
When wind the slip-prone yarn such as waxed yarn, contact pressure is relaxed and the winding
