5.23 Parameter Group 30-** Special Features
5.23.1 30-0* Wobble Function
The wobble function is primarily used for synthetic yarn winding applications. The wobble option is installed in the drive controlling
the traverse drive. The yarn moves back and forth in a diamond pattern across the surface of the yarn package. To prevent a build-
up of yarn at the same points at the surface, this pattern must be altered. The wobble option can accomplish this by continuously
varying the traverse velocity in a programmable cycle. The wobble function is created by superimposing a delta frequency around a
center frequency. To compensate for the inertia in the system, a quick frequency jump can be included. Suitable for elastic yarn
applications, the option features a randomized wobble ratio.
