- the operator O controls, by the control device 70, the rotation of the forme cylinder 6, which completes winding the subsequent image 12 on the forme cylinder 6.
- the rotation of the forme cylinder 6 exerts a traction T6 (Figs 9 and 10) on the subsequent plate 12, which automatically picks up the subsequent plate 12 of the primary attachment mechanism 31, because the traction T6 is greater than the torque exerted by the elastic return member 32.
- the operator O activates, by the control device 70, the locking device 60 to fix the upper portion of the subsequent plate 12 to the plate cylinder 6 (FIG.16).
- the elastic return member 32 After winding up the subsequent plate 12 on the forme cylinder 6, the elastic return member 32 returns the primary fastening mechanism 31 in a waiting configuration (FIG.8), in which the operator O can hook a new one later picture 12.
- the operator O controls the descent of the print module 4 in the production position, in which the plate cylinder 6 is at the level of the transport system 2.
- the closing of the safety cover 80 is controlled automatically, for example enslaved on the descent of the print module 4 (Fig. 17).
- the converting machine 1 can again produce, to print the pattern of the subsequent shot 12 on the next sheets of cardboard.
- the printing module 4 thus allows the operator O to go out alone a large front plate 11 and to pose alone a subsequent large image 12.
