Abstract
The invention concerns a method of controlling the input station in a letter-sorting installation, the input station having a scanning and reading device and a mechanical letter-storage path in which letters are conveyed after being scanned by the scanner, the position x at which the address of each letter is read along the storage path being controlled so that x remains between specified values x.sub.0 and x.sub.max. The invention calls for the number y of uncoded letters along the storage path to be determined in an auxiliary control circuit and the value of y used to generate the control signal u for control of the input station by a control unit.
