1. A processing machine (01) for processing sheets (02), comprising at least one application unit (600) and at least one sheet sensor (622) associated with the at least one application unit (600), wherein the at least one sheet sensor (622) is arranged upstream of the at least one application unit (600) along a transport path for the sheets (02), wherein the at least one sheet sensor (622) is configured to detect an arrival time of the sheets (02) at a position of the at least one sheet sensor (622), wherein the at least one application unit (600) comprises at least one printing couple (614) having a forme cylinder (616) and an individual drive which is associated with the forme cylinder (616), wherein the at least one application unit (600) has at least one processing point (621), wherein the at least one sheet sensor (622) is configured to control a position and/or rotational speed of the forme cylinder (616) in a closed loop and/or an open loop, and wherein the processing machine (01) comprises a shaping device (900) which has a plate cylinder (901) with an individual drive and has a processing point (909) associated with the plate cylinder (901), wherein:
at least one uniquely dedicated sheet sensor (622) of the at least one sheet sensor (622) is associated with each at least one application unit (600), and
upstream of the processing point (909) of the shaping device (900), along the transport path for the sheets (02), at least one additional sheet sensor (922) is arranged, which is configured for controlling a position and/or rotational speed of the plate cylinder (901) of the shaping device (900) in a closed loop and/or an open loop, and in dependence of which the transport speed of the sheets (02) are able to be adjusted by accelerating and/or decelerating at least one sheet (02) of the sheets (02) relative to a processing speed of the processing machine (01) at a relevant position using at least one part of a transport means (700) upstream of the processing point (909) of the shaping device (900).
