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.

Apparatus in spinning preparation for separating foreign objects at a high-speed roll for opening or doffing fibre material

In an apparatus in spinning preparation for feeding a plurality of charging shaftsto, especially a mixer, with fiber material that is transported for example pneumatically in a supply channeland deflected into the charging shafts by means of deflecting devices, each charging shaft is closable at its upper end by means of a rotary gatewhich, in its open position, closes off the cross-section of the supply channel. In order to increase the efficiency by means that are simple in terms of construction and, above all, to improve the transmission of the drive movement to the movement of the rotary gate, the rotary gate co-operates with a drive elementwhich imparts a rotary movement to the rotating axle of the rotary gate.
