Abstract: 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.

Abstract: To detect product defects during the production of mailing products, hygiene products or folded paper products, optical imaging sensors or capacitive sensors monitor at least one characteristic parameter or feature of the products successively moving through the production machine, to detect an actual value of each characteristic parameter or feature of each product. The detected actual value is compared with a stored nominal value for the respective characteristic parameter or feature. The result of the comparison is used to initiate or control a further measure, such as ejecting a defective product from the production line, marking a defective product so that it can be visually recognized and manually removed from the production line, or initiating corrective measures to correct the cause of the defect. The characteristic parameters or features relate to the dimensions, the position, and/or the form of the product or parts of the product.
