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.
