NANOFIBER SHEET DISPENSER
A nanofiber sheet dispenser that houses a nanofiber forest from which a nanofiber sheet can be drawn is described. Using the nanofiber sheet dispenser, a nanofiber forest disposed on a substrate can be moved, transported, and/or shipped with a reduced risk of damage relative to transporting a nanofiber sheet. Techniques are also described for configuring the nanofiber sheet dispenser so that a nanofiber sheet can be conveniently drawn from the forest and, in some cases, drawn so as to form a nanofiber yarn that is continuous with both the nanofiber sheet and the nanofiber forest, the latter of which is within the nanofiber sheet dispenser.
CLEANING DEVICE FOR A YARN FORMING ELEMENT OF AN AIR-SPINNING NOZZLE AND METHOD FOR CLEANING A YARN FORMING ELEMENT OF THIS TYPE
The invention relates to a cleaning device for a yarn forming element of an air-spinning nozzle, to a spinning position of an air-spinning machine and to a method for cleaning a yarn forming element of this type. In order to provide a spinning position of an air-spinning machine and a method for cleaning a yarn forming element of an air-spinning machine which allow long and trouble-free operation with constant quality and strength of the yarn produced, it is provided that the cleaning device has a cleaning strip and a storage unit for providing and retracting the cleaning strip, a fixed end of the cleaning strip being fastened to the storage unit, and a free end of the cleaning strip being able to be provided for cleaning and retracted again after the cleaning. Furthermore, the cleaning device has a cleaning strip guide for feeding the free end of the cleaning strip to the yarn forming element of the air-spinning nozzle for mechanical cleaning.

Drawing Frame for Drawing a Strand-Like Fiber Assembly and Textile Machine Equipped Therewith
A drawing frame for a textile machine includes at least two drawing frame modules, with module having a roller and an opposite counter-roller supported on an individual carrier, wherein the roller is movable back and forth independently of the rollers of the other drawing frame modules between a load position and a release position. For each drawing frame module, the roller bodies of the roller and of the counter-roller are out of contact in the release position and are pressed together in the load position in order to guide the fiber assembly in a clamping manner. Each carrier includes a first carrier section and a separate second carrier section, wherein the roller is supported on the first carrier section and the counter-roller is supported on the second carrier section. A guide is configured between the first carrier section and the second carrier section so that the first carrier section and the second carrier section are displaceable relative to each other.

Air Spinning Machine and Method for Producing a Yarn
An air spinning machine for producing a yarn from a fiber structure includes a spinneret with an internal eddy chamber. A spindle in the spinneret has an intake opening and extends into the eddy chamber. An annular gap is formed between an outside surface of the spindle and an inside wall of the eddy chamber. Air jets in the spinneret introduce air into the eddy chamber to impart twist to the fiber structure at the intake opening. An interior draw-off channel in the spinneret has a longitudinal axis by means of which the yarn is withdrawn from the eddy chamber. The air jets are aligned in a direction relative to a front side of the spindle around the intake opening so that some of the air introduced via the air jets during a spinning operation enters the annular gap and a remainder of the air enters the draw-off channel.

YARN RETURN UNIT FOR RETURNING A YARN AS WELL AS A WORKSTATION OF A TEXTILE MACHINE COMPRISING A YARN RETURN UNIT
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.
