A dispenser is described for dispensing nanofiber yarns that includes a housing that defines an inlet, an outlet, and a chamber. A spool, around which is wound a length of nanofiber yarn, is disposed within the chamber defined by the housing. The nanofiber yarn is threaded from the chamber through the outlet and can be dispensed in a controlled way that reduces the likelihood of developing knots within the nanofiber yarn, and which facilitates convenient application of the yarn onto an underlying surface. In some cases, the dispenser can be used to concurrently dispense an adhesive or other polymer along with the nanofiber yarn.

Disclosed is a first creel bobbin brake, a creel bobbin assembly, a creel and a creel method. The first creel bobbin brake is arranged for applying a braking torque to a first shaft of a first creel bobbin. The first creel bobbin brake includes a strap that is provided with a first end, a second end and a strap body extending in a longitudinal direction between the first end and the second end, wherein the strap further includes an opening in the strap body, wherein the strap body and the opening are arranged to taper from the first end towards the second end, wherein the strap is arranged to be wound around the first shaft of the first creel bobbin over at least two revolutions, and wherein the second end is insertable through the opening with each revolution.

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.

A method at a workstation of a spinning machine or winding machine supplies an auxiliary thread from a thread nozzle to a suction assigned to the workstation, the auxiliary thread stretched between the thread nozzle and the suction. The auxiliary thread is severed to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction. The thread section extending into the thread nozzle is grasped with a thread receiver such that the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver. The thread section extending into the thread nozzle is severed to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver. The thread section coming from the thread receiver is transferred to the suction of the workstation. The thread section coming from the thread receiver is grasped with a capture arrangement adjacent a tube at the workstation prior to starting a process of winding the thread section coming from the thread receiver onto the tube.
