Abstract
An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a rotary cutter operating at a first velocity, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed. In a further preferred embodiment of the present invention, the speed of the rotary cutter and right angle turn mechanism are controlled to adjust a quantity of sheets that would be generated from displacement traveled due to inertia during a deceleration of the system to a stop.
