<p>To permit, selectively, positioning of drums or cylinders in rotary sheet printing machines having, selectively, different functions, a cylinder layout is provided, generally in form of an inverted Y, which permits placing, selectively, blanket cylinders, transfer drums, chain system delivery drums and the like at predetermined locations so that, with six bearing positions (9-14) in a standard side wall (1), different printing modes and arrangements providing for single or multiple prime (P, P') and verso (V) printing can be effected, the printing positions being, for example, formed by bores for bearings of the respective cylinders which, if not used, can be plugged or left as space areas, preferably with marked centers, in the side walls; a standard side wall thus can be provided for multiple types of machines which also permit subsequent expansion of machine printing capability without exchange of side wall support or frame structure. The standardized side walls and layout permits application of single prime printing (P), verso printing (V), prime and verso printing (P, V) or multiple prime printing (P, P') with or without verso (V) printing.</p> |
