Abstract
In a method and apparatus for length measurement of a flat good in a goods processing system having first and second stations, each having a sensor in the transport direction of the flat good, a control processor implements a path control and counts encoder pulses of an encoder in the first station. An event is determined by the sensor of the second station, and an associated numerical value Z1 of the encoder pulses is stored in the control processor, as is a numerical value Z2 for a distance between the two sensors is also stored. An additional event is determined by the sensor of the first station, and an associated numerical value Z3 of the encoder pulses is stored. As soon as both events are present, Z2 and the difference Δ=Z3−Z1 are added by the control processor, and the sum is used to designate the length.
