Signature conveyor system with automatic phase adjustment

摘要

A signature conveyor system with automatic phase adjustment capability includes a conveyor for conveying a plurality of sheets in a conveyance direction wherein the conveyor is subdivided into a plurality of conveyor spaces and a motor for causing the conveyor to move at a speed in the conveyance direction. Packer boxes are spaced along the conveyor and each packer box periodically releases one of the sheets above the conveyor at a release time as the conveyor moves past the packer box. A phase changer is operatively coupled between the conveyor and the packer boxes and adjusts the release time based upon the speed of the conveyor. <IMAGE>
