  • Paper sheet feeding device
    Patent number: 4188026
    Abstract: A feeding attachment for paper sheets of variable small formats is readily attached to and removed from the existing printing machine for printing of smaller format paper sheets or regular printing as desired. The attachment is capable of feeding the paper sheets in an ideal attitude for printing to the printing machine even if each of such sheets has a non-uniform thickness such that, when the sheets are stacked in a pile, each such sheet of the pile will be tilted progressively relative to the horizontal from the bottom towards the top of the pile.
