Abstract

A device for singulating overlapping flat mailings in an upright position in a path of travel has several singulating sections arranged along the path of travel. Each singulating section has conveyor belts spaced apart from each other and above each other and transporting the mailings. At an opposite side of the path of travel, each singulating section has retaining elements acting on the mailings with a friction force and at a height between the conveyor belts. A speed of travel of the conveyor belts in each singulating section is higher than the speed of travel of the conveyor belts of the respective singulating section upstream in the direction of travel. Further, individually mounted deflection rollers of the conveyor belts of both adjacent singulating sections are arranged at different heights along a common axis at each transition between the singulating sections.
