In an embodiment of a steel sheet having high Young's modulus, the steel can include in terms of mass %, e.g., C: 0.0005 to 0.30%, Si: 2.3% or less, Mn: 2.7 to 5.0%, P: 0.15% or less, 0.015% or less, Mo: 0.15 to 1.5%, B: 0.0006 to 0.01%, and Al: 0.15% or less, with the remainder being Fe and unavoidable impurities. One or both of {110}&#x3c;223&#x3e; pole density and {110}&#x3c;111&#x3e; pole density in the &#x215b; sheet thickness layer can be 10 or more, and a Young's modulus in a rolling direction can be more than 230 GPa. Other embodiments can include, e.g., Mn: 0.1 to 5.0%, N: 0.01% or less, and one or more of Mo: 0.005 to 1.5%, Nb: 0.005 to 0.20%, Ti: at least 48/14&#xd7;N (mass %) and 0.2% or less, and B: 0.0001 to 0.01%, at a total content of 0.015 to 1.91 mass %.

A turn bar apparatus is incorporated in a rotary press for reversing a web position during running thereof. The turn bar apparatus includes an upstream side turn bar, and a downstream side turn bar disposed along a web running direction. Pull rollers are disposed on an upstream side and a downstream side of the upstream side and downstream side turn bars, respectively. The puller rollers are controlled in such a manner that the peripheral speeds of the pull rollers are faster than a running speed of the web.

Turn bar apparatus

A rotary printing machine body is provided with a U-shaped longitudinal portion for mounting an interchangeable drum unit. A pair of left and right interchangeable drum unit moving devices are mounted on the left and right printing machine body frames and adapted to move an interchangeable drum unit resting on a carriage into the mounting portion formed in the printing machine body and to move an interchangeable drum unit from the mounting portion onto the carriage. A pair of left and right fixing devices are also provided for fixing the interchangeable drum unit in the mounting portion to the printing machine body.
