METHOD FOR LENGTH MEASUREMENT OF A FLAT GOOD IN A GOODS PROCESSING SYSTEM, AND ARRANGEMENT FOR IMPLEMENTATION OF THE METHOD

Method and arrangement for length measurement of a flat good in a goods processing system, with a first station (1) and a second station (2), wherein the second station (2) is arranged downstream of the first station in the transport direction of the flat good. Given length measurement, sensors are used that belong to different stations (1, 2). The control unit is programmed to implement a path control and to count the encoder pulses of an encoder (13) of the first station. An event is determined by means of a first sensor (DW-S1) of the second station (2), and an associated numerical value Z1 of an encoder pulse counter (14) is stored in a first register (R1) of the control unit of the first station. A numerical value Z2 for a distance d between two sensors (AZ-S3, DW-S1) is stored in a second register (R2) of the control unit (10) of the first station (1). An additional event is determined by means of the sensor (AZ-S3) of the first station, and an associated numerical value Z3 of the encoder pulse counter 14 is stored in a third register (R3) of the control unit (10) of the first station (1). As soon as both events are present, the numerical value Z2 and the difference .DELTA. = Z3 ¨ Z1 of the counter stations Z3 and Z1 are added by means of the control unit (10) of the first station.
