Abstract (en)
[origin: WO0142122A1] The invention relates to a method for reducing the polygon effect that occurs over the course of the reversing of a chain, which can be used for a pedestrian conveyor, especially an escalator or moving walkway. To this end, a different rotational speed is superimposed upon the rotational speed of the reversing wheel via the electric drive which indirectly or directly acts upon said reversing wheel.
