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

Abstract

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.
