  • Device for conveying a sheet through a typographic machine
    Patent number: 7594658
    Abstract: A device for conveying a sheet through a typographic or printing technology machine reliably transfers a sheet from a cylinder to a trailing-edge gripper system and includes a chain conveyor, grippers for holding and taking over the leading margin of the sheet from a cylinder and grippers fixed to endless chains for holding the trailing, rear margin of the sheet. When the grippers for the trailing margin pass the cylinder, the grippers are guided in a closed state along a path outside a revolution contour of a support surface and, having passed the cylinder, the grippers are guided in an open state along a path to a radial level of the rear margin held in auxiliary grippers.
