Device for the adjustment of a unit in a flexographic printing machine which includes at least two. Each unit includes a continuous tensioned paper web (13) moving successively through each of the units, ink means (16) with an ink fountain (22), an inking roller (20), printing means (26) with at least one co-operating plate holder roller (28) movable in vertical translation and designed to be in contact with the inking roller (20), means (30) for guiding the paper web to be printed. The device is characterized in that the first (44) and fourth tangent points are stationary, the second (46) and third (48) points are always simultaneously disposed within or without the two straight lines (41, 43) perpendicular to the straight line (45) joining the first (44) and fourth (50) points and passing by the first (44) and fourth (50) points so as to maintain constant the web length between the tensioning rollers (36, 38) and an almost identical setting of the plate in relation to the paper web (13). |
