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.

Abstract: A spindle for manufacturing yarns has a spindle rotor with a central axis. A fiber guide duct extends substantially from the central axis radially outwardly for guiding a first fiber radially outwardly. The first fiber, after exiting the fiber guide duct, is guided under formation of a fiber balloon to a centering point that is located on an extension of the central axis of the spindle rotor. At least one inlet line that extends substantially radially toward the fiber balloon is provided for introducing a flowable medium into a space limited by the fiber balloon.
