Abstract (en)
[origin: US4846062A] A sheet-turning drum in a sheet-fed rotary printing press for optionally first printing or perfecting printing is provided that is simple to assemble and adapted to be changed over for differing printing requirements. To this end, the sheet-turning drum is subdivided into a unitary main member and a cylindrical drum envelope. The latter having a sheet support surface and flanges disposed on its end faces for securing the envelope between mounting flanges on the main member. The sheet support surfaces of the drum envelope can be in the form of a smooth metal surface, an ink-repellent fabric or support rollers retained on carrying rods.
