Bogenueberfuehrungsrolle fuer Mehrfarben-Rotationsdruckmaschinen

摘要

A sheet transfer roller for use in multicolor printing presses is formed by a number of sets of arcuate elements arranged concentrically with the roller axis and slidably mounted on respective guides carried by the roller and extending parallel to the roller axis. The arcuate element can be clamped to the guides at the desired positions by clamping screws. It can be arranged that sheet supporting members carried by the arcuate elements engage a sheet to be transferred at selected relatively print-free regions.
