Folding apparatus of an offset web-fed printing press and offset web-fed printing press
A folding apparatus of an offset web-fed printing press includes a first transport means formed as belt conveyor system for a web-shaped printing material and configured such that belts thereof can be driven at a speed, which corresponds to the speed of the printing material, and a first cutting means arranged in the region of the first transport means configured such that it severs the printing material in a format-variable manner in those sections not covered by the belts of the first transport means, and a second transport means arranged downstream from the first transport means and formed as belt conveyor system, the belts of which are offset relative to the belts of the first transport means transversely to the transport direction of the printing material, configured such that the belts thereof can be driven at a speed larger than the speed of the belts of the first transport means.

Apparatus for printing on cylindrical objects having device to prevent loading of objects onto mandrels
An apparatus is disclosed for printing images on generally cylindrical objects. The apparatus comprises an impression station that includes a movable imaging surface for bearing an ink image; and a transport mechanism for advancing the objects through the impression station, comprising a drive member rotatably connected to a plurality of rotatable mandrels, each for mounting a respective one of the objects, the transport mechanism being configured to cause each object to rotate during passage through the impression station such that, within a nip region of the impression station, the surface of the object makes rolling contact with the imaging surface, thereby causing the ink image to be impressed on the object. An impression platen is provided opposite the imaging surface within the nip region, the impression platen being configured to apply a force, directly or indirectly, to the objects to ensure rolling contact between the objects and the imaging surface.
