Abstract
In a web-fed rotary offset printing machine, operating preferably with variable-format cylinders, both sides of the printing machine are covered, during the operation and resetting of the machine, so that no access, in particular no access to the printing units, is possible. For this purpose, an access module is used between the printing-units, which module is equipped laterally with covers which resemble window roller blinds and cannot be opened while the machine is in operation.
