The method is used to operate a ring spinning system (1) which contains a ring spinning machine (2) having a plurality of spinning positions (21) and a winding machine (3) having a plurality of winding positions (31). Yarn (92) is spun at one of the spinning positions (21) and wound up to a cop (91). Values of a spinning parameter are determined at different times during the winding of the cop (91) and stored as spinning data. The cop is transported from the spinning position (21) to one of the winding positions (31). At the winding position (31) the yarn (92) is rewound from the cop (91) onto a yarn bobbin (93). Values of a yarn parameter are determined at at least two different times during the rewinding of the cop (91) and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other in such a way that they relate to the same yarn section. Based on the spinning data and yarn data assigned to each other, an intervention is made on the ring spinning machine (2).

Method for monitoring a textile machine having a plurality of workstations and a textile machine having a plurality of workstations, more particularly spinning positions, the textile machine having: a textile machine control unit, which is 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, which is connected to the textile machine control unit in order to optically output the result of the check of the at least one selected production figure to be checked for exceeding the allocated, specified limit value. In order to provide a method for monitoring a textile machine having a plurality of workstations and a textile machine having a plurality of workstations, said method and said textile machine enabling quick detection and identification of workstations whose production figures exceed specified limit values, 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 means of different light signals.

A method is provided for operating a semi-automatic or fully automatic cross-wound package-manufacturing spinning machine that has a plurality of identical, adjacently arranged, and at least partially autonomous workstations. Each of the workstations has a spinning device for manufacturing a thread and a winding device including a package holder for winding the thread onto a cross-wound package. Once an end of a lot being processed at one of the workstations has been reached, the workstation is stopped. A requirement that at least one manual service action must be carried out at the workstation before a lot change at the workstation is displayed at the workstation.

The invention relates to a method of controlling a sensor (3) of physical quantities and/or an optical signalling means (7) on a textile machine, especially a yarn manufacturing machine, in which the sensor (3) of physical quantities is primarily intended to detect the state at a workstation and the optical signalling means (7) is primarily intended to provide visual information about the state of a workstation, group of workstations or machine. The sensor (3) of physical quantities and/or the optical signalling means (7) is deliberately switched to the secondary operating mode other than the primary purpose of the sensor (3) and/or the signalling means (7), working operations are performed in this secondary operating mode and subsequently the sensor (3) of physical quantities and/or the optical signalling means (7) targetedly switches back to the primary operating mode.

In addition, the invention relates to a textile machine, especially a yarn manufacturing machine, having at least one row of workstations comprising at least one sensor (3) of physical quantities and/or one optical signalling means (7), whereby the sensor (3) of physical quantities is primarily intended to detect the state at a workstation and the optical signalling means (7) is primarily intended to provide visual information about the state of a workstation, group of workstations or machine and the sensor (3) of physical quantities and/or the optical signalling means (7) are connected to a control and evaluation device (6). The control and evaluation device (6) comprises means for targetedly switching the sensor (3) of physical quantities and/or the optical signalling means (7) to the secondary operating mode in which the sensor (3) of physical quantities and/or the optical signalling means (7) is used in the same place for at least one purpose other than its primary purpose.

A textile machine includes a protective exterior cover, a slotted yarn access formed in the protective cover, and a safety guard shielding at least a portion of the slotted yarn access. The safety guard includes a guard body mounted to the protective cover proximate the slotted yarn access. The guard body has a fastener edge residing adjacent a first side of the slotted yarn access, and a free edge residing adjacent a second side of the slotted yarn access. The free edge of the guard body extends above and across the slotted yarn access and forms an unobstructed space on the second side of the slotted yarn access allowing yarn to pass around the free edge, underneath the safety guard and through the protective cover.
