ABSTRACT:
To permit, selectively, ready access by an operator to printing systems of a multiple system printing machine in which the printing systems are located above and below a laterally introduced web of paper into the machine, the paper path is arranged to be guided, selectively, with a horizontal portion either following a vertical portion, to permit an operator to stand beneath the paper web for access to the lower printing systems (FIG. 1) or, selectively, to position the vertical portion adjacent the printing machine to permit an operator to stand on a movable platform (11) and have access to the printing system above the paper web (FIG. 2), a paper guide roller (6) is vertically movable between an upper position (6, 13, 14) and a lower position (6', 13', 14'). Paper web tension can be maintained by an additional deflection guide roller (8) which is tilted, together with the platform (11) to an engagement position (FIG. 2: 8'), or the paper may hang through (FIG. 3).
