Abstract:
1. A sheet-fed offset rotary printing press with a convertible press mechanism, comprising: an upstream transport cylinder which conveys a sheet by holding a leading edge thereof; a downstream transport cylinder which is arranged downstream of said upstream transport cylinder in a sheet convey direction and holds a trailing edge of the sheet being conveyed by said upstream transport cylinder; a convertible press mechanism which causes said downstream transport cylinder to hold the sheet in a turned state when the sheet is to be transferred from said upstream transport cylinder to said downstream transport cylinder; and a pair of air blowing means, arranged at different heights on outer sides of two ends in a widthwise direction of the sheet, for blowing air toward a center in the widthwise direction of the sheet which is turned over by said convertible press mechanism, so as to separate the sheet from said upstream transport cylinder.
