CPC D01H 1/115 (2013.01) [B65H 51/16 (2013.01); D01H 15/002 (2013.01)] | 7 Claims |
1. A process for operating an air-jet spinning device after a spinning interruption, in which a drafting system for warping a sliver is connected upstream of the air-jet spinning device in a direction of the sliver and a yarn take-up device for drawing off a yarn spun by the air-jet spinning device is connected downstream, the process comprising:
after a spinning interruption, a yarn end of the spun yarn run onto 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 then transferred through a yarn guide channel, having a plurality of pneumatically engageable channel sections coupled to each other, into a first area of an outlet opening of a spinning cone,
the yarn end is transported to a second area of an inlet opening of the spinning cone by the yarn take-up device, which is reversibly driven by a first single motor, and is positioned there within the air-jet spinning device at a distance in front of the inlet opening,
the drafting system of a relevant workstation, which warps the sliver, is raised and the sliver is conveyed through a sliver guide of a 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, and the drafting system of the relevant workstation is driven by a second single motor.
