Abstract
A method of and a device for controlling the orientation and the alignment of individual sheets of paper travelling on a sheet conveyor are provided. Each sheet passes over a pair of closely spaced rotating disks inserted between upstream and downstream sheet conveyor sections. Each sheet is locally engaged with each disk in a limited contact area. The contact areas between the sheet and each disk are varied so as to achieve a target orientation or alignment of the sheet.
