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.
