Method for length measurement of a flat good in a goods processing system, having a first station and a second station, wherein the first station is a supply station and the second station is a dynamic scale, wherein the second station is arranged downstream of the first station in the transport direction of the flat good G, wherein each of the stations (1, 2) has at least a motor, an encoder (13, 26), and a sensor that are connected with a control unit (10, 20), wherein the control unit (10, 20) is programmed to implement a path control, characterized by the steps: - provision of an encoder pulse counter in the control unit of the first station, and counting of the encoder pulses of the encoder of the first station by means of the encoder pulse counter of the control unit of the first station, - determination of an event by means of a first sensor (DW-S1) of the second station, and storage of an associated numerical value Z1 of the encoder pulse counter in a first register of the control unit of the first station, wherein the event, which is determined by the sensor (AZ-S3) of the first station relates to the detection of the trailing edge of the flat good G, - storage of a numerical value Z2 for a distance d between two sensors (AZ-S3, DW-S1) in a second register of the control unit of the first station, wherein the sensors (AZ-S3 and DW-S1) belong to different and adjacent stations (1 and 2), - determination of an event by means of the sensor (AZ-S3) of the first station, and storage of an associated numerical value Z3 of the encoder pulse counter 14 in a third register of the control unit of the first station, wherein the event which is determined by the sensor (DS-S1) of the second station relates to the detection of the leading edge of the flat good G, - summation of the numerical value Z2 and of the difference Δ = Z3 - Z1 of the counter states Z3 and Z1 by means of the control unit of the first station as soon as both events are present. - provision of an encoder pulse counter in the control unit of the first station, and counting of the encoder pulses of the encoder of the first station by means of the encoder pulse counter of the control unit of the first station, - determination of an event by means of a first sensor (DW-S1) of the second station, and storage of an associated numerical value Z1 of the encoder pulse counter in a first register of the control unit of the first station, wherein the event, which is determined by the sensor (AZ-S3) of the first station relates to the detection of the trailing edge of the flat good G, - storage of a numerical value Z2 for a distance d between two sensors (AZ-S3, DW-S1) in a second register of the control unit of the first station, wherein the sensors (AZ-S3 and DW-S1) belong to different and adjacent stations (1 and 2), - determination of an event by means of the sensor (AZ-S3) of the first station, and storage of an associated numerical value Z3 of the encoder pulse counter 14 in a third register of the control unit of the first station, wherein the event which is determined by the sensor (DS-S1) of the second station relates to the detection of the leading edge of the flat good G, - summation of the numerical value Z2 and of the difference Δ = Z3 - Z1 of the counter states Z3 and Z1 by means of the control unit of the first station as soon as both events are present.
