Abstract

In an apparatus in spinning preparation for separating foreign objects at conveying equipment for fiber material, at least one separation device is associated with the conveying equipment. The separation device comprises an arrangement for producing a blast of air that flows in the direction onto the conveying equipment and generates an air flow that detaches the foreign objects from the conveyed fibers and carries them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the conveying equipment and connected to a compressed air pipe and to valves. To reduce the proportion of good fibers in the waste in a simple manner, and to allow a more selective action of the blast air current, a bar member for mounting the blast nozzles is present and the nozzles are integrated in the bar member.
