  • Patent number: 6575456
    Abstract: For conveying flat articles (10) in dense conveying streams, grippers (3) conveyed one behind the other by conveying elements (1) are used, each gripper (3) holding one of the articles gripped in an edge zone. For increasing the possibilities for changing the orientation of the flat articles (10) during such conveyance, the grippers (3) are attached to the conveying elements (1) by asymmetrically-projecting gripper arms (2) and the grippers (3) are designed to be rotated through 360° around the gripper arm axis. The device can be used universally, particularly for held conveyance of printed products and it is very easily adjustable for differing applications.

  • Patent number: 6572103
    Abstract: A method of tracking a document in a system for feeding and transporting documents includes detecting a document trailing edge at a fixed location upstream of a feeder. The system includes a feeder stage and a transport stage downstream of the feeder stage. The feeder stage includes the feeder and a separator. The method further includes tracking a position of the document trailing edge as the document trailing edge moves between the fixed location and the feeder, and performing an operation dependent on the document trailing edge position when the document trailing edge is between the fixed location and the feeder.
