ABSTRACT:
Improved apparatus for rotary printing of a strip of paper (1) or similar material, comprising a printing roller (2) provided with a cliche (3) brought into contact with a back pressure roller (4) and a screened roller (5) to quickly interrupt and resume the printing of the paper (1), said means comprising a support (20) to which the printing roller (2) is rotatingly connected and which is, in turn, rotatingly connected to a fixed pivot (21) eccentric with respect to the printing roller (2) and around which rotation occurs by means of an actuator (22). Washing means (15) are also provided for the cliche (3) and a mobile support (30) of the ink roller (6) which allows it to be distanced from the screened roller (5) so as to create a space (8) which promotes the formation of a film of ink on the screened roller (5) itself suitable to keep it damp and prevent drying. (FIG. 2 )
