Abstract: A sleeve magazine for a textile machine and operational method include multiple transport elements each with a plurality of holders configured for holding a sleeve, wherein each transport element is driven to move the holders and sleeves to a removal point. A removal device at the removal point removes the sleeves from the holders. A controller controls movement of the individual transport elements such that the holder of at least one transport element is moved with the sleeve thereon to the removal point. The controller actuates the removal device to remove the sleeve from the holder at the removal point while the holders of the remaining transport elements are maintained outside of the removal point so as not to interfere with removal of the sleeve from the holder at the removal point.

Abstract: A device for contactless measurement of one or more parameters of a linear textile formation (e.g., yarn) includes a yarn sensor with at least two mutually independent detection zones for one or a combination of the parameters of yarn presence, yarn movement, or yarn quality. The individual detections zones are arranged in defined positions relative to at least two different yarn paths of the yarn at a workstation depending on changed states of the yarn at the workstation so that at least one of the parameters is measured in each of the detections zones.

Abstract: A method of controlling a yarn compensating arm at a workstation of a spinning machine, wherein the yarn is initially withdrawn from an intermediate vacuum storage device. Before emptying the yarn from the storage device, the compensating arm is deflected past its working and into an out-of-the-working-range position, wherein the yarn is captured by the compensating arm and also deflected to the out-of-the-working-range position to form a non-working yarn reserve. The compensating arm is retained by a force at the out-of-the-working-range position while the yarn is emptied from the storage device. Upon being emptied from the intermediate vacuum storage device, the yarn exerts a tensile force on the compensating arm that overcomes the retaining force causing the compensating arm to return to its working range position.

Abstract: A method at a workstation of a spinning machine or winding machine supplies an auxiliary thread from a thread nozzle to a suction assigned to the workstation, the auxiliary thread stretched between the thread nozzle and the suction. The auxiliary thread is severed to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction. The thread section extending into the thread nozzle is grasped with a thread receiver such that the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver. The thread section extending into the thread nozzle is severed to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver. The thread section coming from the thread receiver is transferred to the suction of the workstation.

Abstract: The invention relates to a method for controlling means of a workstation of a textile machine producing yarn (1) comprising a compensating unit (9) for the compensation of a yarn (1) loop with a compensating member (6, 8) and, optionally, with a rotary drum (7), whereby on the compensating unit (9) are further arranged internal means (10,15) and external means (14, 16) of detecting the compensating unit (9), in which the information from the internal means (10,15) and the external means (14, 16) of detection is used by a controller of work nodes of the workstation for the controlling activity of the control unit (11) and selection of activation of software procedures is performed on the basis of the information about the state in which the workstation is at a given moment (the course of yarn (1) formation and winding, servicing activity).

Abstract: A method is provided for controlling movement and operation of an attending device of a yarn manufacturing textile machine, wherein the attending device moves along a row of workstations arranged next to each other to perform operations at the workstations. The method controls the movement of the attending device along the work stations and operations of the attending device based on success statistics of the operations at the workstations to achieve an overall increased efficiency of the textile machine. An operational stay of the attending device at a particular one of the work stations is terminated without waiting for a result of the operation being performed by the attending device at the particular workstation.

Abstract: A method for preparing of a workstation of an air-jet spinning machine for the resumption of a yarn spinning process after an interruption includes inserting the yarn end into an inlet opening of the spinning nozzle and transporting the yarn in a reverse motion with aid of the spinning nozzle and a fiber feeding device to a guide channel disposed before the spinning nozzle. A spinning-in yarn end is formed on the yarn in the guide channel. A yarn reserve is formed in an underpressure yarn storage device in from of a yarn winding device. The reverse motion of the yarn to the guide channel is performed by reverse motion of a yarn drawing-off mechanism at the workstation. A workstation configured to perform the method is encompassed by the invention as well.

Abstract: A method is provided for resumption of a yarn spinning process on an air-jet spinning machine wherein, after an interruption of yarn spinning has occurred, the yarn is guided back to a working path downstream of a spinning nozzle, or the yarn is stopped in a controlled manner in the working path, with an end of the yarn situated downstream of the spinning nozzle. The yarn end is introduced into an outlet opening of the spinning nozzle, and the yarn is transported in a reverse path with the aid of the spinning nozzle and a sliver feeding device to a guide channel upstream of the spinning nozzle. A spinning-in yarn end is formed on the yarn in the guide channel, and a yarn reserve is formed in an underpressure yarn storage device upstream of a yarn winding device. Winding of the yarn onto a bobbin is started before, simultaneously with, or after the formation of the spinning-in yarn end.

Abstract: A method for depositing a yarn end of a yarn on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes detecting the yarn end on the bobbin via an attending device. After detecting the yarn end, the yarn end is passed to devices at the workstation, and with the devices at the workstation, the yarn end is directed in a defined manner outside of a profile of a standard yarn package wound on the bobbin prior to the yarn end being deposited onto the tube outside of the yarn package profile.

Abstract: A method for depositing a yarn end on a bobbin wound on a tube in a defined manner during winding of yarn on the bobbin at a workstation of a spinning and winding machine includes terminating spinning production of the yarn at the workstation to create a yarn end. The yarn end is then prepared with working devices at the workstation, including rotating the bobbin in a direction opposite to a winding direction during production of the yarn. A yarn reserve is formed, and the yarn end is then deposited in a defined manner on the tube outside of the profile of a standard yarn package.
