At least two yarns are connected with each other. It is at least a so-called core yarn and at least one so-called effect yarn, which is arranged by the air texturing around the core yarn around. If this loft changes in the course of the thread, it is called a fantasy yarn, otherwise a so-called textured yarn.
  • the core yarn determines the strength of the fantasy yarn.

This length is determined by the length of the thread run between the thread guides and the thread guide edge at maximum deflection of the thread.

If the axis of rotation of the rotary body is arranged substantially perpendicular to the yarn path of a yarn in the region of the yarn guide edge, the distance between the rising edge of the yarn guide edge and the plane of rotation of the disk increases sinusoidally against the direction of rotation of the rotary body.
