ABSTRACT:
A transport device for paper sheets incorporates driven rollers which frictionally engage the paper sheets and are mounted on shafts arranged parallel with one another in the transport direction. Filaments extending in the transport direction are utilized to bias the paper sheets from below against the rollers. The filaments permit the paper sheets to glide or slide thereover and extend between the rollers in a lower tangential plane, said filaments being mounted elastically at one extremity thereof. A slight inclination of the shafts of the rollers causes the paper sheets to be transported while engaging a lateral guiding edge to accomplish transportation of said sheet in an accurately aligned manner.
