Beschreibung
Zusammenfassung:	Method of and apparatus for producing shaped effect yarns with or without ladders. A stretched main thread and an effect thread are fed in parallel relationship through a rotating hollow spindle carrying a yarn body with a fastening thread. The effects are shaped and fastened by the fastening thread after the stretched main thread and the loose effect thread simultaneously pass through a set of rollers whose pressure is continuously regulated. The main and effect threads are not twisted in the hollow spindle with the fastening thread but twist with it between a differentiator-regulator which rotates with the spindle and pulling rollers downstream thereof.
