A spinning station of a spinning machine for producing a thread from a sliver. A thread end is taken up by a take-up device and transferred to a preparation device downstream from a vortex chamber of the spinning device, the thread end is subsequently treated in the preparation device and then transferred to the vortex chamber, a drafting system for supplying a sliver to the vortex chamber is powered up, wherein an exit roller pair of the drafting system is accelerated to a predetermined draw-off speed, and the sliver is spun onto the thread end in the vortex chamber and a draw-off device for drawing off the thread spun in the vortex chamber is powered up and accelerated up to the draw-off speed. The speed of the exit roller pair and/or of the draw-off device increases non-linearly and/or approaches the predetermined draw-off speed non-linearly around the end of powering up.

Spinning station of an air-jet spinning machine and method for carrying out a piecing process at such a spinning station

A drafting system for conveying a sliver to an inlet opening of a vortex chamber of an air-jet spinning device, for a drafting system having an exit roller pair and at least one additional drafting system roller pair and/or apron roller pair. A sliver is supplied at a spinning station of an air-jet spinning machine for the production of a thread to the vortex chamber. The exit roller pair can be driven decoupled from the at least one additional pair of drafting system rollers and/or apron rollers. In the method, the roller pair is driven for combing the sliver end after a spinning interruption at a predetermined combing speed and the at least one stretching mill roller and/or belt roller pair upstream of the starting roller pair is stopped or operated at a holding speed associated with the combing speed, which is at most 10% of the combing speed.

Sliver preparation

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.

Yarn deflection unit

A drafting system unit for a drafting system of a spinning machine having a first top roller and a second top roller spaced apart therefrom, characterized in that an apron cage to which negative pressure can be applied is arranged between the first top roller and the second top roller for guiding an air-permeable apron in circulation jointly around the apron cage and an apron top roller, the apron top roller being formed by the first top roller or by a third top roller that is assigned to the apron cage and arranged on the same side as the first and second top roller in relation to the fiber band being transported. The apron cage has at least one through-opening, to which negative pressure can be applied, for applying suction air to the fiber band running between the first and second top roller, through the air-permeable apron.

Drafting system unit and drafting system for a spinning machine

An open end rotor spinning machine with plural workstations each having a yarn spinning device, a yarn take-off mechanism loaded by a reversibly driven single drive and a winding device for producing a cross-wound bobbin. The spinning device has a spinning rotor, a fiber band opening roller and a single motor-driven fiber band feed cylinder. Each workstation () has a mechanism () for cutting to length a yarn () retrieved from the bobbin (), a yarn storage mechanism () and a drive mechanism () for lifting the bobbin () from its drive roller (). During the piecing process, a manually activatable control mechanism () activates the drive () of the yarn take-off mechanism (), the drive () of the fiber band draw-in cylinder () and the drive mechanism () to lift the bobbin () according to a predetermined piecing program.
