Abstract (en)
[origin: EP0395864A2] In a dedusting device for angle bars in folding apparatuses for printing machines, the angle bar (8) is surrounded, parallel to its axis and in the paper-running direction, at least in the region of one of the lateral edges of the paper-running path (10), by a plurality of successive suction chambers (3) in cross-sectionally semicircular arrangement. Discharge electrodes (6), to which a direct voltage is applied, are arranged at the paper inlet (12) in the region upstream of the first suction chamber (3a) and at the paper outlet (14) in the region downstream of the last suction chamber (3n) opposite the angle bar (8).
