1. A sheet diverter and delivery system for receiving a fast moving, continuous web, cutting sheets therefrom and diverting alternate sheets to one of two delivery paths for subsequent processing, all while maintaining substantially continuous control of the individual sheets, comprising:

  • first conveyor means including cutting means for cutting a fast moving continuous web into a stream of separate sheets and directing the sheets along an original travel path at an original speed;

    sheet controlling means disposed downstream of said first conveying means and along the original travel path of said first conveying means to securely engage the lead edge of the web before it is cut;

    second conveyor means and third conveyor means each having an entrance end and an exit end and each including at least a pair of closely spaced face to face belts, said entrance ends being positioned downstream of said sheet controlling means, said second conveyor means disposed above said third conveyor means, said second and third conveyor means being driven at a speed at least approximately the original speed of the sheets and being positioned on alternate sides of the original travel path and diverging from the original travel path at approximately the same angle;

    a pair of rotating diverter means positioned in close proximity to the entrance ends of said second and third conveyor means for alternately diverting the separate sheets from the original travel path into said second and third conveyor means without the use of a stationary diverter or guide member, each of the diverter means being synchronized with the speed of the one of the second and third conveyor means with which the diverter means is associated to engage the leading edge of the sheet to be diverted at a sufficiently small angle and directly divert the leading edge of the sheet under substantially continuous control into the grasp and control of the associated conveyor means before the trailing edge of the sheet is disengaged from said sheet controlling means so as to avoid damage and misalignment of the sheet, the diverter means thereafter continuing to support substantially the entire length of the sheet as the sheet is taken up by the associated conveyor means and ultimately released by said sheet controlling means; and

    means connected with each of said second and third conveyor means for decelerating and shingling said sheets for delivering two separate streams of shingled sheets to a subsequent processing station.
