A process for operating an air-jet spinning device such that after a spinning interruption the yarn end of the spun yarn accumulated on a take-up package is picked up by a suction nozzle and transferred to a yarn end preparation device. The yarn end is processed in the yarn end preparation device and is then transferred to a first area of an outlet opening of the spinning cone, the yarn end is pneumatically transported to a second area of an inlet opening of the spinning cone and is positioned there within the air-jet spinning device at a distance in front of the inlet opening, the drafting system of the relevant workstation is raised and the sliver is conveyed through a sliver guide of the nozzle block into the second area of the inlet opening of the spinning cone and there spun onto the prepared yarn end of the spun yarn.

Process for operating an air-jet spinning device, yarn guide channel and air-jet spinning machine comprising such a yarn guide channel

A yarn guide channel for arrangement between a spinning device and a winding device of a spinning machine producing a take-up package in which a yarn guide channel forms a passage channel for a yarn running between the spinning device and the winding device. The yarn guide channel has a plurality of pneumatically engageable channel sections coupled to each other, having at least a first channel section, a second channel section and a channel connection section disposed between the first and second channel sections, in which the channel connection section has a mouth for supplying compressed air into the yarn guide channel for generating a pneumatic overpressure in the first channel section associated with a pneumatic suction effect in the second channel section.

A yarn deflection unit for a textile machine, having a housing comprising a curved wall section for forming a radially outer wall section of a curved yarn deflection channel. The solution proposed by the invention is distinguished in that the curved wall section has a yarn guiding groove extending along the curvature for receiving and guiding a yarn.
