Abstract

An apparatus for transporting sheet material such as bank notes, comprising separate endless conveyor belt systems which are conducted about guide or deflection rollers of varying diameter and which extend parallel adjacent to the conveyance path. The individual sheets are held between the belts of the two systems by friction. In order to avoid different-size reversals when rollers with varying diameters rotate, the angle of contact of the conveyor belts is selected in response to the diameter of the rollers such that the reversal remains constant over the whole of the length. In the case of a finitely thick belt the word reversal means the velocity of the inner fibre running on the rollers in relation to the neutral fibre in %.
