Abstract: A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine includes a yarn-guiding unit, a single traversing drive configured with the yarn-guiding unit, and a conversion element configured with the single traversing drive such a rotational movement (?) of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit. The single traversing drive is a rotating motor. A sensor is disposed to detect at least a middle position of the yarn-guiding unit.

Abstract: A tow feeding apparatus which requires no continuous observation, shortens the reset time when tow is wound around pinch rolls for feeding into a case, and operates safely, includes guide rolls for leading a tow to a winding roll or pinch rolls, a winding roll apparatus provided between the guide rolls and pinch rolls at a normal position for winding up a tow around a winding roll when wrapping trouble occurs at the pinch rolls. A pinch roll apparatus for feeding the tow from the guide rolls through the winding roll apparatus into a case, and a transport device for transporting the winding roll apparatus from the normal position to a reset position behind the pinch roll apparatus when wrapping trouble occurs. A cutter shears the tow along the tow route before the pinch roll apparatus. An exchanger for substituting the pinch roll apparatus with another set of pinch rolls, and a detector for detecting wrapping of a tow around the pinch rolls are further included.
