A method for converting a letter envelope production machine from a set-up mode to a normal production mode includes extracting letter envelope test samples via an extraction point of the letter envelope production machine, and moving a work station in the area of the extraction point between the extraction point at which letter envelope test samples are extracted and a production position in which letter wraps are produced. The work station is in the extraction position during the set-up mode and the letter envelope test samples are extracted at the extraction point. The letter envelope production machine continues running at a base speed during the conversion so that the movement of the work station to the production position during the operation of the letter envelope production machine will occur at base speed and set-up results obtained during the prior set-up mode will be maintained.
