Abstract
In an apparatus in spinning preparation for separating foreign objects at a roll for opening or doffing fiber material, at least one device for separating the foreign objects is associated with a face of the roll. That device comprises an arrangement for producing a current of blast air flowing onto the face for detaching the foreign objects and carrying them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the roll. To permit separation and allow rapid changes of the action of the blast air current, a bar for mounting the blast nozzles is present and the outlet of the blast nozzles is locally displaceable in relation to the face of the roll.
