Abstract
A transport track extends through first and second stations for transporting paper postal items through the stations. The first and second stations are equipped with first and second drives for driving circulatable surfaces of the respective station along the transport track. The second drive is controlled for driving at least one of the second station's circulatable surfaces at a circumferential speed higher than the circumferential speed of the first station's circulatable surfaces. While a stack of postal items passes from the first station to the second station, highest normal force exerted thereon by the circulatable surfaces of the second station is larger or smaller than the highest normal force exerted thereon by the circulatable surfaces of the first station.
