Method for monitoring a textile machine having a plurality of workstations and a textile machine having a plurality of workstations, the textile machine having: a textile machine control unit, designed to capture different production figures of the individual workstations and to check whether the production figures exceed specified limit values; an input unit for inputting the limit values and selecting at least one production figure to be checked out of the set of production figures to be checked; and an indicating unit. The indicating unit has a plurality of signal units, which are arranged on the textile machine control unit and/or the workstations in question, are associated with the individual workstations and are designed in such a way that the result of the check of the at least one selected production figure to be checked for exceeding the allocated, specified limit value is indicated by different light signals.

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 method for monitoring air flows required for handling a thread and/or fiber band in a spinning machine, and to a spinning machine unit. At least one air flow-generating source is connected to an air flow duct. An air volume flow measuring unit is connected to an evaluation device for data transmission. The air volume flow is measured by the air volume flow measuring unit and the measurement result is transmitted to the evaluation device. The number of productive and/or non-productive spinning positions is detected. An air volume flow target value is determined by the evaluation device. The air volume flow target value is compared with actual value of the measured air volume flow by the evaluation device, the evaluation device making an evaluation on the basis of the comparison as to whether there is an unacceptable deviation between the actual value and the air volume flow target value.

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.

A method for producing an effect yarn on an open-end rotor spinning machine, formed from an alternating line-up of yarn sections and effects consisting of pre-determined thickenings, wherein an effect is produced where the yarn is joined by means of a piecing end, in the piecing region of the yarn located downstream of the piecing end, following a break in the thread. The quality of the yarn produced in this way is improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piecing regions, are eliminated.

Method for producing an effect yarn on an open-end rotor spinning machine, and corresponding effect yarn

A rotor spinning machine of the type comprising a plurality of working stations and a bobbin supplying device extending along the machine, wherein at least two service units supplying the working stations with bobbins are supplied by the supply device and wherein the rotor spinning machine comprises a control device for controlling the service units. The control device is configured in such a way that it suppresses a subsequent bobbin request from the second service unit in the event of an existing bobbin request from the first service unit positioned downstream in relation to the transporting direction of the supply device, until the initially existing bobbin request has been fulfilled.

Rotor spinning machine

A rotor spinning machine has a plurality of spinning stations, each of which comprises an opening roller and a draw-in roller for supplying sliver to the opening roller and each of which is equipped with control devices for individual drives of the draw-in rollers. The control devices each have a connection mechanism, to which an additional control card can be attached for producing effect or novelty yarn with predetermined effects. The control card comprises a processor, which meets the elevated computing power requirements for producing effect or novelty yarn and can be activated via a data bus system.

Rotor Spinning machine

An apparatus for holding a textile bobbin on a support roller and for facilitating the exertion of a controlled bearing pressure from the textile bobbin against the support roller. The apparatus comprising a creel for grasping the textile bobbin, a shaft for supporting the creel for pivotable movement relative to the support roller, a lever mechanism for applying a variable torque to the creel as a function of pivoted movement of the lever mechanism, and an adjustment device for varying the torque applied to the creel via the lever mechanism. The adjustment device comprises a rotatable eccentric element disposed to act on the lever mechanism for establishing an adjustable base position of the lever mechanism according to a rotated position of the eccentric element.
