A method for the register-true alignment of sheets (1) before the transfer to a sheet-processing machine with the assistance of a carrier (7,9) that is movable in the machine cycle and is driven as a function of a signal, in order to feed the sheets individually to an aligning stop. To permit exact and reliable alignment even at high machine speeds with an uncomplicated mechanism, the signal is generated when a sheet edge (12) to be fed passes a predetermined location between the carrier (7,9) and aligning stop (5), and in response to the signal, the carrier performs a preset movement, identical from sheet to sheet, by which the carried-along sheet (1) is fed to the aligning stop with a speed greater than zero, but substantially less than the maximum sheet speed during the feeding movement. The method is particularly suitable for side-edge alignment, but is also suitable for leading-edge alignment.
A method for proper alignment of sheets comprising the steps of:
