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.
Claims19
A method of controlling at least one of the orientation and alignment of individual sheets of paper travelling on a conveyor, wherein each sheet passes over a pair of closely spaced rotating disks and the sheet is locally engaged with each disk in a limited contact area, and the contact areas between the sheet and each disk are varied so as to achieve a target orientation or alignment of the sheet.
A device for controlling at least one of the orientation and alignment of individual sheets of paper travelling on a conveyor, comprising a pair of closely spaced rotating disks arranged on a sheet travel path between upstream and downstream sections of the conveyor, an a pair of engagement members each associated with one of said disks to define a sheet passage gap, and each of said engagement members being movable opposite a respective disk within a 90° sector of the disk defined between a radius parallel to and a radius perpendicular to the sheet travel direction.
