WIRING PREPARATION TO SEPARATE FOREIGN OBJECTS IN A HIGH-SPEED ROLL TO OPEN OR UNLOAD FIBER MATERIAL, FOR EXAMPLE, COTTON, SYNTHETIC OR SIMILAR FIBERS. The present invention relates to a spinning preparation apparatus for separating foreign objects into a high speed roll for opening or discharging fiber material, for example cotton, synthetic fibers or the like, wherein at least one device for separating the fibers foreign objects is associated with the coated face of the opening roller or discharge roller, the device of which comprises an arrangement for producing an injection air stream that flows towards the coated face and generates an air flow that detaches foreign objects from the face. coated and carries foreign objects away, the arrangement comprising a plurality of air injectors which are disposed across the width of the opening roller or discharge roller and are connected to a compressed air tube and valves. In order to allow in a structurally simple manner a consistent separation quality, namely to influence the proportion of good fibers in the waste, and to allow a rapid change in the action of the injection air stream, a bar for mounting the air injectors is fitted. present and the outlet of the air injectors in a displaceable location relative to the coated face of the opening roller or discharge roller.
