A method is performed at a spinning machine that includes a plurality of spinning stations at which different yarn lots are spun. The method transports tubes from multiple tube magazines to the spinning stations. At the spinning station, a yarn is spun from a sliver deposited in a can and is wound onto the tube. An identical marking associated with a respective one of the different yarn lots is provided on the following components: each of the tubes, each of the tube magazines, a display device at the spinning station, a monitor at a machine control system, the cans at the spinning station, and a service unit that travels alongside of the spinning stations.

A method determines an electrical characteristic at a spinning machine or winder, wherein the electrical characteristic is one or both of electrical power and electrical energy consumption. The spinning machine or winder includes a plurality of adjacently arranged workstations that each include an electrical working element. A total electrical characteristic for the spinning machine or winder is measured with a central measuring unit. The workstations are subdivided into at least two production groups that operated independently of one another. A distribution key is defined and used to calculate the electrical characteristic specific to each of the production groups by allocating the total electrical characteristic to the production groups with the distribution key. The specific production group electrical characteristics are displayed at the spinning machine or winder and transmitted to a computer that is at a higher control level than the spinning machine or winder.

A method for controlling a display on a spinning machine or winder having a plurality of same-kind workstations and a plurality of displays includes assigning one of the displays to at least two of the workstations, wherein each display includes a display area. During normal operation of the workstations, information regarding the individual workstations assigned to the particular display is simultaneously displayed in respective subareas of the display area. When required by changed operating states at the work stations, a surface area of the subareas is changed to display information regarding at least one of the workstations on a larger subarea. An associated spinning machine or winder is also provided.

A method is provided for operating a spinning machine or winder that includes a plurality of same-kind workstations and a plurality of input terminals situated with the workstations. The method includes at least intermittently configuring at least one of the input terminals as a master terminal. Commands are entered for operation of all or a group of the workstations via the master terminal. Designation of the master terminal is changed to one or more different ones of the input terminals at different points in time. A spinning machine or winder that practices the method is also provided.

A textile machine includes a plurality of workstations adjacently situated in a longitudinal direction of the textile machine, the workstations combined to form multiple sections wherein each section includes one or more of the workstations. A plurality of electrical supply units supply electrical energy to the workstations, wherein one of the electrical supply units is assigned to each section or to each workstation. A cooling arrangement includes at least one coolant circuit configured with the electrical supply units such that waste heat generated by one or more of the electrical supply units is absorbed by a coolant within the coolant circuit and transported to a common discharge area of the textile machine.

A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine includes a yarn-guiding unit, a single traversing drive configured with the yarn-guiding unit, and a conversion element configured with the single traversing drive such a rotational movement (&#x3c9;) of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit. The single traversing drive is a rotating motor. A sensor is disposed to detect at least a middle position of the yarn-guiding unit.

A method for automatically piecing a thread at a workstation of a textile machine, includes seeking an end of the thread on a surface of a bobbin with a suction nozzle and unwinding the thread from the bobbin counter to a regular draw-off direction of the thread and sucking the thread into the suction nozzle. The bobbin is driven in a direction of reverse rotation with a drive. A thread loop is draw-opened in the thread and moved towards a piecing unit via movement of a feeder unit. The bobbin is driven in the direction of reverse rotation during the drawing-open of the thread loop such that the thread is unwound from the bobbin. A speed of reverse rotation of the bobbin is coordinated with movement of the feeder unit.

A yarn return unit for returning a yarn into a delivery unit of a textile machine during a piecing process includes a yarn-guiding section configured to guide and position the yarn with respect to the delivery unit. A blowing unit generates an air flow for returning the yarn from the yarn-guiding section into the delivery unit, the blowing unit defining a flow direction of the air flow. The yarn-guiding section includes an open contour that defines an insertion area through which the yarn is inserted into the yarn-guiding section transversely to the flow direction of the air flow.

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. The thread section coming from the thread receiver is grasped with a capture arrangement adjacent a tube at the workstation prior to starting a process of winding the thread section coming from the thread receiver onto the tube.
