Abstract
A chain conveyor for a sheet-processing printing machine has conveyor chains bearing gripper systems for transporting sheets. The chains are revolvable, during operation, along closed chain tracks having at least substantially circular segment-like chain track sections. A guide rail device is provided for guiding the conveyor chains. A rail section forms part of the guide rail device. The rail section, when loaded by one of the conveyor chains, is deflectable counter to a restoring force and, at a first end of the rail section, adjoins one of the substantially circular segment-like chain track sections. A sheet-processing printing machine having such a chain conveyor is also provided.
