Abstract
A device for aligning sheets prior to transferring the sheets to a sheet-processing machine includes at least one sheet-gripping device by the aid of which the sheet to be aligned is displaceable, the sheet-gripping device having at least one positioning table displaceable by an actuating drive in at least one of a sheet travel direction, transversely to the sheet travel direction, and in a direction wherein it is pivoted about an axis extending in a direction orthogonal to the sheet travel direction, the sheet to be aligned being fixable on the positioning table; and a method for aligning sheets by the device.

A device for aligning sheets prior to transferring the sheets to a sheet-processing machine, comprising at least one sheet-gripping device by the aid of which the sheet to be aligned is displaceable, said sheet-gripping device having at least one positioning table displaceable by an actuating drive in at least one of a sheet travel direction, transversely to said sheet travel direction, and in a direction wherein it is pivoted about an axis extending in a direction orthogonal to said sheet travel direction, the sheet to be aligned being fixable on said positioning table.
A method of aligning sheets prior to transferring the sheets to a sheet-processing machine, which comprises gripping by at least one sheet retainer a respective sheet to be aligned, displacing the sheet into a desired position, and contactlessly aligning at least one of a leading sheet edge in a direction transverse to a sheet travel direction and of lateral sheet edges in a direction parallel to the sheet travel direction.
