  • Patent number: 5120043
    Abstract: The present invention is embodied in a document feeder of an inserting machine. The feeder comprises a frame, a feed deck coupled to the frame, a separator wheel assembly for separating and feeding individual documents. The separator assembly includes a separator wheel disposed above the feed deck and a drive for the separator wheel. The separator wheel assembly can be adjusted to a position relative to the feed deck commensurate with the material being fed. The improvement comprises the separator wheel assembly being biased against a cam. The cam is located above the separator wheel assembly, wherein the separator wheel assembly is in a first position for singulating and feeding sheets when the cam is in a normal position, and wherein the separator wheel assembly raises to a second position when the cam is rotated to an eccentric position, whereby the singulating and feeding of individual documents is prevented when the separator wheel assembly is in the second position.
