  • Patent number: 6817604
    Abstract: A device for adjusting conveyors for printing presses that process flat products or further processing units (40) arranged downstream therefrom, in which are received belt movers (1) containing a plurality of individual belts (5) for transporting the flat products, the belt movers including guide rollers (6) and setting rollers (7), which have a drive (2), and use tensioning devices (3) which keep constant the tension in the individual belts (5) of the belt mover (1). Accommodated in the further processing unit (40), whether it be a folder with pins or a folder that works without pins, arranged downstream from the rotary press, are shafts (16, 28, 34) having elements (25, 31, 39), which are arranged in a stationary mount and guide the individual belts (5). Supported on these so as to enable sliding in the axial direction, symmetrically with respect to the machine center (13), are movable elements (20, 27, 36), which guide, drive, and/or prestress the individual belts (5).
