Abstract
A paper handling system includes an acceleration conveyor having an acceleration belt operating at an acceleration speed. The system includes a pinning structure operably positioned to pin paper to the acceleration belt. The pinning structure is a rotary feeder which includes a plurality of flexible bristles extending radially from a roller into engagement with the acceleration belt. The speed of the acceleration belt is sufficiently high to create a suction phenomena such that when paper is pinned to the acceleration belt with the rotary feeder, the paper will be accelerated to a paper speed substantially equal to the acceleration speed. The system also includes a blower system operative to facilitate carrying the paper off of the acceleration belt across a transition gap between the acceleration belt and a product belt.
