ABSTRACT:
Offset printing press which comprises, in combination, a set of means making it possible for it to carry out, either independently or simultaneously, sheet-fed or web-fed printing. These webs are presented equally well either as perforated and prefolded pages or as reels. A set of mechanical movement pieces, working together with the removable components, makes it possible, depending on the types of printing to be carried out, to provide the press with twenty possibilities of different printing modes. A movable press-cylinder 17 (FIG. 3), working together with the blanket of the removable blanket cylinder 3A, makes it possible to prevent the web-fed printed matter, during its printing, from passing through the press and, by so doing, to make these two modes of feeding and printing, sheet-fed and web-fed, totally independent of each other. The same type of removable device as that fitted on the mixed press, also mounted on a sliding frame 64 (FIG. 4), can be fitted on a set of existing sheet-fed offset presses, in order to make it possible for them to carry out successive sheet-fed and web-fed printing.
