Claim:
A device for conveying a sheet through a typographic machine, the device comprising: a rotatable cylinder having at least one gap formed therein, grippers disposed in said at least one gap for holding the leading, front margin of the sheet, and at least one carrying element forming a cylinder-jacket-shaped sheet support surface, said support surface having a revolution contour; a chain conveyor having rotatable sprockets, endless chains placed over said rotatable sprockets, and grippers fastened to said endless chains for holding and taking over the leading margin of the sheet from said cylinder and for holding the trailing, rear margin of the sheet; coaxially revolving support elements for the sheet, said support elements being disposed between said sprockets associated with said cylinder and being in rolling contact with the sheet resting on said support surface; coaxially revolving auxiliary grippers disposed between said sprockets associated with said cylinder, for holding the trailing margin of the sheet; an actuating device for opening and closing said grippers; and a drive for said cylinder and said sprockets; said grippers for the trailing margin being guided in a closed state along a path outside said revolution contour of said support surface, while passing said cylinder; and said grippers for the trailing margin being guided in an opened state along said path to a radial level of the trailing margin held in said auxiliary grippers, after passing said cylinder.
