Abstract: A device (1) for drawing in and intermediately storing a thread (2), comprising a suction chamber (3), wherein the suction chamber (3) includes an entry opening (8) and an exit opening (9), which define a direction of flow, wherein negative pressure can be applied to the exit opening (9) in order to generate an air flow (4). Moreover, the device comprises a depositing surface (5) arranged in the suction chamber (3), on which the thread (2) can be intermediately stored, and a flow element (6) arranged in the suction chamber (3), with the aid of which the air flow (4) can be directed through the suction chamber (3).

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 method for automatically piecing a thread at a workstation of a textile machine, includes seeking an end of the thread on a surface of a bobbin with a suction nozzle and unwinding the thread from the bobbin counter to a regular draw-off direction of the thread and sucking the thread into the suction nozzle. The bobbin is driven in a direction of reverse rotation with a drive. A thread loop is draw-opened in the thread and moved towards a piecing unit via movement of a feeder unit. The bobbin is driven in the direction of reverse rotation during the drawing-open of the thread loop such that the thread is unwound from the bobbin. A speed of reverse rotation of the bobbin is coordinated with movement of the feeder unit.

Abstract: A yarn return unit for returning a yarn into a delivery unit of a textile machine during a piecing process includes a yarn-guiding section configured to guide and position the yarn with respect to the delivery unit. A blowing unit generates an air flow for returning the yarn from the yarn-guiding section into the delivery unit, the blowing unit defining a flow direction of the air flow. The yarn-guiding section includes an open contour that defines an insertion area through which the yarn is inserted into the yarn-guiding section transversely to the flow direction of the air flow.
