Claim 10:
11. A method for processing sheets (02), wherein a processing machine (01) comprises 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) detects 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) which has a forme cylinder (616) and an individual drive 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) emits a signal for closed-loop control and/or open-loop control for synchronizing the arrival time of the sheets (02) at the at least one processing point (621) with an arrival time of a forward edge of a printing forme of the forme cylinder (616), in a circumferential direction of the forme cylinder (616), wherein the at least one sheet sensor (622) controls a position and/or rotational speed of the forme cylinder (616) in a closed loop and/or in 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 which has a processing point (909) associated with the plate cylinder (901), characterized:
in that at least one additional sheet sensor (922), which controls 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, is arranged upstream of the processing point (909) of the shaping device (900), along the transport path for the sheets (02), and in dependence of which, the transport speed of the sheets (02) is adjusted by accelerating and/or decelerating at least one sheet (02) of the sheets (02) relative to a processing 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),
in that a print length (l2) is adjusted by altering a circumferential speed and/or the rotational speed of the forme cylinder (616) of the at least one printing couple (614) relative to a circumferential speed and/or rotational speed of an impression cylinder (617) associated with the forme cylinder (616), and
in that adjustment of the print length (l2) is achieved by accelerating and/or decelerating the forme cylinder (616) while at least part of a printing region of a lateral surface of the forme cylinder (616) is located at the processing point (621).
