Device for adjusting a cutting reference.

printing machine comprising: a) at least one printing mechanism (2) for printing a web (B), b) a longitudinal cutting device (3a, 3b) for longitudinally cutting the band (B) in a first branch band (B1) and at least a second web strand (B2) further, c) a device (8, 9) to collect the web strands (B1, B2) or to collect the web strands (B1, B2) respectively with at least one branch of additional band, comprising a device turning bars (8), d) a transverse cut (25) for the transverse cutting of the web strands (B1, B2) together, e) and an adjusting device (10) of crop marks, to adjust a crop of the web strands (B1, B2) based on the cross section, comprises a first deflecting means (11) for deflecting the first web strand (B1) about a first deflection axis and to deflect the second web strand (B2) about a second axis of sviacion, a second deflection device (12) is housed in a frame (14, 16) being movable relative to the first deflection device (11), so that can be modified path length of the second web strand ( B2) with respect to the path length of the first web strand (B1) by a movement of the second deflecting means (12) relative to the first deflection device (11), characterized in that f) the adjusting device (10) crop mark is arranged in front of the device turning bars (8), seen in the conveying direction (F) of the band (B).
