A process for operating an air-jet spinning device after a spinning interruption, an air-jet spinning machine having a yarn guide channel and such a yarn guide channel. The air-jet spinning device is preceded in the direction of travel of the fibre web by a drafting system for warping a fibre web and a yarn take-up device, which is optionally driven individually by a motor, for taking off a yarn spun by the air-jet spinning device is connected downstream. 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 arranged downstream of the air-jet spinning device in the direction of the sliver run, 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.

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 is produced having a functional core and a covering. The core is either an active functional core having electronic components or passive components and may be monofilament or multifilament. The core and covering are introduced together such that the covering protects the core and gives the core a more comfortable feel such that the yarn may be used in textile applications. The core may be covered by various spinning methods such as air jet or Vortex air jet spinning, ring spinning, open end, or friction spinning. The yarn may also be processed in a single or double covering operation. In one embodiment, the yarn is woven into clothing.

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.

A drawing and spinning apparatus of mixed yarns for air spinning machines with multiple feeds comprises at least a first and a second introducer element, an air spinning device, a drawing device, interposed between the introducer elements and the air spinning device, an air spinning chamber, an introducer nozzle shaped to receive the webs from the drawing device into respective insertion channels and introduce the webs into the spinning chamber according to a longitudinal feeding direction. With respect to a cross-section plane perpendicular to the longitudinal feed direction, groove bottoms of each of the two insertion channels of the webs into the chamber are aligned along a segment which is offset by an eccentricity with respect to a geometric centre of the chamber itself, through which a symmetry axis of the spinning chamber passes, the eccentricity being less than 5% of a maximum diameter of the spinning chamber.

An air-jet type spinning device comprising at least one injection hole configured to introduce a flow of compressed air in a spinning chamber. A fibre feeding device facing the spinning chamber feeds the fibres in the spinning chamber. A spinning spindle is at least partially inserted in the spinning chamber and fitted with a spinning channel for the transit of yarn obtained from the fibres.

A yarn is produced having a functional core and a covering. The core includes a functional component embedded therein that may be active, passive, or a combination thereof. The core may also be monofilament or multifilament. The core and covering are woven together such that the covering protects the core and gives the core a more comfortable feel such that the yarn may be used in textile applications. The core may be covered by various spinning methods such as air jet or Vortex air jet spinning, ring spinning, open end, or friction spinning.
