Abstract
In the case of a friction spinning machine having at least one spinning unit containing two friction rollers that are arranged next to one another to form a wedge-shaped yarn forming gap serving as the yarn forming zone, it is provided that in the area located opposite the yarn forming point the friction rollers are covered by a housing side and that by means of periodically switchable means, an air flow is produced between the housing side and the rollers.
Claims23
An open-end friction spinning machine having at least one spinning unit containing:
- two friction rollers that are arranged next to one another to form a wedge-shaped yarn forming gap serving as a yarn forming zone,
- a housing side means disposed adjacent the friction rollers at the side thereof opposite the yarn-forming gap,
- and periodically switchable means for producing an air flow between the housing side means and the friction rollers.
An open-end friction spinning machine having at least one spinning unit containing:
- drivable friction surface means defining a yarn forming zone,
- a housing side means disposed adjacent the friction surface means at the side thereof opposite the yarn forming zone,
- and periodically switchable means for producing an air flow between the housing side means and the friction surface means.
