  • Patent number: 5394229
    Abstract: A retard feeder system having a noise suppression device which feeds sheets from a stack of sheets to a sheet transport path. The device includes a sheet feeding friction device for engaging and moving sheets in a direction toward the path, a retard pad positioned adjacent said sheet feeding device to form a retard nip to permit selective feeding of individual sheets through the retard nip to the path, and a raised portion in the path for corrugating the sheet as portions of the sheet are engaged in the retard nip. The corrugation of the sheet helps to minimize the sheet flutter and vibration while it is within the retard nip by increasing the beam strength of the sheet and thereby decreases the audible noise created by the vibrating sheet.
