Station and yarn guide of rotor spinning machine

Abstract

The invention relates to a station and a yarn guide of a rotor spinning machine, the rotor spinning machine is provided with a rotor spinning device used for spinning fed fiber slivers and a yarn guide unit arranged at the downstream of the rotor spinning device, the yarn guiding unit is provided with an inlet hole used for receiving the yarn coming out of the outlet hole of the air-jet spinning device, a yarn guiding channel used for guiding at least the air-jet spinning yarn coming out of the air-jet spinning device, and a yarn guiding piece used for being arranged between the outlet hole of the air-jet spinning device and the inlet hole of the yarn guiding unit. In order to provide a rotor spinning machine station which ensures that a yarn end is reliably fed back into a spinning device and a yarn guide piece used on the rotor spinning machine station, the yarn guide piece is provided with a channel body, the yarn guide unit is provided with a through channel which is provided with a connecting part and an end part, wherein the connecting part is used for being connected with the spinning device and arranging a first opening end of the through channel in an outlet hole area of the spinning device, the end part is opposite to the inlet hole, and the end part is matched with a contour of the yarn guide unit surrounding the inlet hole in order to receive the yarn coming out of the inlet hole.

Description

technical field [0001] The invention relates to a station of an air-jet spinning machine, which has an air-jet spinning device for spinning a yarn from a fed fiber sliver, and a yarn guide unit arranged downstream of the air-jet spinning device, the yarn guide unit having a Inlet apertures for receiving yarn from the outlet apertures of the air-jet spinning device and yarn guide passages for guiding at least the yarn from the air-jet spinning device therethrough, and for arrangements in spinning devices such as air-jet spinning devices The yarn guide between the outlet hole of the yarn deflection unit and the inlet hole of the yarn deflection unit. Background technique [0002] In the textile industry, various methods and spinning devices are known in connection with the production of textile yarns. For example, ring spinning machines and / or open-air rotor spinning machines have long been widespread and proven. Furthermore, so-called open-end spinning machines are also kno...

AI Technical Summary

Problems solved by technology

[0005] In known air spinning machines having a yarn guide unit arranged downstream of the air spinning device in the yarn withdrawal direction and having a yarn guide channel, due to the inlet opening of the yarn guide unit and the opposite spinning There is no yarn guide area between the outlet holes of the yarn device, so there is an impermissible return of the yarn received by the winding package, so that it cannot be reliably guided into the open-end spinning device to complete the piecing
