Abstract
An apparatus for changing operational plate cylinders during rotary press operation is provided. This apparatus is possible to substantially equalize an actual print count to a set print count before change of operational plate cylinders. This can eliminate waste to print undesired recording paper (paper loss) and lead to cost down. A rotary press includes at least two or more plate cylinders (P), drive means ( ) for driving the plate cylinders (P) and switching means ( ) for selectively switching the plate cylinders (P) in a printable state and in an unprintable state. In the apparatus ( ) for changing operational plate cylinders during rotary press operation, input console means ( ) is at least available for designating (x) an earlier operational plate cylinder (FP) that is switched from the printable state to the unprintable state by the switching means ( ) and a later operational plate cylinder (RP) that is switched from the unprintable state to the printable state by the switching means ( ) among the two or more plate cylinders (P), and setting (y) a print count before change of operational plate cylinders.
