摘要:
Sheet carrier device disposed so as to be axially and radially adjustable on a transfer drum in a multicolor rotary printing machine and having axially shiftable carriers extending in circumferential direction on the casing of the drum, sheet carrier elements being interchangeably mounted on the carriers and displaceable in circumferential direction of the drum, the sheet carrier elements having supporting edges whereon a sheet being carried is supported when the carrier elements are in operating position. In a first embodiment the invention includes lines disposed circumferentially on the transfer drum and having a hook at least one end thereof for hooking the lines into the drum casing, the sheet carrying elements being formed with respective bores through which the sheet carrying elements are threaded on the lines, the sheet carrying elements having a square cross section concentric to the bores formed therein, respectively, and having the respective supporting edge thereof projecting from the square cross section, and a guide band mounted on the casing surface of the transfer drum and shiftable in axial direction thereof, the sheet carrying elements being disposed on the guide band so as to be pivotable through 90.degree.. In a second embodiment the invention includes a guide rod axially mounted on the drum casing, stirrups forming a circumferentially extending circular segment, respectively, and being shiftable in axial direction on the guide rod, the sheet carrier elements being formed with a clamping opening by which the sheet carrier elements are mounted on the stirrups.
