Abstract: A textile machine producing cross-wound packages with a plurality of identical workstations which are arranged in the area of the longitudinal sides of the textile machine and each of which has a winding device, and equipped with a tube supply device which includes a central tube magazine and at least one tube conveyor belt installed in the area of the longitudinal sides of the machine, in which case a cross-wound package can be removed, if necessary, from the winding device of the relevant workstation on the textile machine producing cross-wound packages and can be transferred to a cross-wound package transport device running the length of the machine, and an empty tube provided on the tube conveyor belt of the tube supply device can be inserted by means of a tube gripper into the winding device of the relevant workstation.

Abstract: A textile machine for producing cross-wound packages, the machine being equipped with a plurality of workstations arranged next to one another on both longitudinal sides of the machine and having a cross-wound package transport apparatus. The cross-wound package transport apparatus has a first transport device, arranged between the two rows of workstations for conveying cross-wound packages, and a handling apparatus for moving cross-wound packages from the first transport device to the second transport device. The handling apparatus is arranged between the end regions of the first transport device.

Abstract: A textile machine for producing cross-wound packages, comprising a plurality of workstations, each of which has at least one pneumatic consumer, and comprising a suction system which has at least one vacuum source to which the pneumatic consumers of the workstations are connected via a machine-length vacuum duct arranged in the region of the central axis between two rows of workstations. In order to modify such a textile machine producing cross-wound packages in such a way that it is ensured that the required minimum spinning vacuum is always available at all workstations of the textile machine during spinning operation, according to the invention the textile machine producing cross-wound packages has, in addition to the vacuum duct, a machine-length bypass duct which is also installed in the region of the central axis and is arranged above chain ducts for service units.

Abstract: A tube storage and transport device for a textile machine producing cross-wound packages, which has a plurality of similar workstations arranged side-by-side on both longitudinal machine sides, having a central tube magazine and two empty-tube conveyor belts arranged in the region of the longitudinal machine sides is provided. To improve the known tube storage and transport devices, and in particular to optimize the clock times that can be achieved during the empty-tube delivery, the tube magazine has at least two elevator units, that the elevator units have stacked and vertically displaceable holders for empty tubes, that the holders are designed for the empty tubes to be set down in a manner oriented the longitudinal direction of the machine, and that each of the elevator units is connected to one of the empty-tube conveyor belts and is designed in such a way that empty tubes are removed from the elevator units from the longitudinal machine side and transferred onto the empty-tube conveyor belts.

Abstract: A method for operating a textile machine with several identical workstations which each have a basic requirement for negative pressure for regular production operation and an additional requirement for negative pressure following an interruption to production at the workstation, and with a vacuum system with limited suction force to exert the negative pressure on the workstations. A minimum negative pressure (pmin) is set and the number workstations simultaneously supplied with additional negative pressure is limited so that the minimum negative pressure (pmin) is always met. In accordance with the invention, a sub-negative pressure (psub) is specified which is below the minimum negative pressure (pmin) and, if a specified event occurs, the number of workstations simultaneously supplied with additional negative pressure is temporarily limited so that the sub-negative pressure (psub) is always met.
