Procedure for accurate alignment of sheets of paper on processing machine

摘要

A signal is generated if an edge of a sheet for feeding passes a predetermined position between the driver (7,9) and stop (5). The driver executes the same sheet to sheet movement preset to the signal and through which the sheet is fed to the stop at a speed which is less than the maximum sheet delivery speed. The stop provides front edge alignment and consists of one for more front lay marks. Side alignment is carried out by one or more side markers.
