Abstract

A spindle for manufacturing a yarn has a spindle body for receiving a fiber supply bobbin from which a fiber is removed radially outwardly to form a fiber balloon and guided to a centering point above the spindle body. A spindle rotor for rotating the spindle body has a central axis. A supply device for introducing a flowable medium into the space limited by the fiber balloon is provided. The supply device has an inlet line with an outlet opening. The inlet line has a section adjacent to the outlet opening extending at least directly upstream of the outlet opening coaxially or parallel to the central axis. At least a portion of the section is rotatable about the central axis and has a fiber guide tube comprising a first end that extends coaxially from the portion and a second end that extends radially from this portion.
