ABSTRACT:
A traveller useful for either Z- or S-twisting in an otherwise conventional twisting or spinning frame. The traveller is provided with a roller which has a cylindrical surface mounted for rotation about an axis which, when in operation, lies in a plane normal to the path of the traveller and which plane contains the axis of the associated spool. The axis of the roller cylindrical surface intersects the rotation axis of the spool at an angle of from 30 to 60 degrees and preferably between 45 and 60 degrees. The traveller, therefore, is independent of rotation direction. Specific length to diameter ratios are disclosed as are relations of roller diameter to thickness of threads and the like engaging the roller during operation.
