ABSTRACT:
Methods and systems employing belt conveyors adapted to feed signatures to a collating conveyor and a control system that regulates the operation of the belt conveyors are provided. The control system is adapted to regulate the speed of the belt conveyors in response to the speed of the collating conveyor, for example, proportional to the speed of the collating conveyor, to minimize or eliminate signature misfeeds. The control system may implement a mathematical algorithm that defines a relationship between the collating conveyor speed and the belt conveyor speeds. The systems and methods may include ancillary feeding devices such as joggers and speeder wheels to optimize the transfer of signatures.
