Patent ID: 7976010

Claim:
Device for singulating overlapping flat mailings in an upright position in a path of travel comprising: first, second, and third singulating sections disposed along the path of travel with an ensemble of conveyor belts, each of said first, second, and third singulating sections having respective conveyor belts of said ensemble of conveyor belts spaced apart from each other and above each other for transporting the mailings, and each of said first, second, and third singulating sections having, at an opposite side of the path of travel, respective retaining elements for acting on the mailings with a friction force and at a height between the conveyor belts, wherein said conveyor belts in said third singulating section are configured to have a speed of travel that is higher than the speed of travel of said conveyor belts of said second singulating section, which is disposed upstream of said third singulating section in the direction of travel, and said conveyor belts in said second singulating section are configured to have a speed of travel that is higher than the speed of travel of said conveyor belts of said first singulating section, which is disposed upstream of the second singulating section in the direction of travel, said first singulating section being provided with a first deflection roller of said conveyor belts of said first singulating section, said second singulating section being provided with second and third deflection rollers of said conveyor belts of said second singulating section, and said third singulating section being provided with a fourth deflection roller of the conveyor belts of said third singulating section, said first and second deflection rollers being disposed at different heights along a common axis at a transition between said first and second singulating sections, and said third and fourth deflection rollers being disposed at different heights along a common axis at a transition between said second and third singulating sections.
