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: A device for spatially orienting blanks having a length in a transport direction has at least one stop roll body rotatable about a rotation axis and having at least one stop element, and a driver transport system for driving the blanks relative to the stop roll body. The driver transport system has at least one driver roller that pushes the blanks against the driver transport system, and at least one roll body roller that pushes the blanks against the stop roll body, wherein the roll body roller is prestressed in contact with the stop roll body. The driver transport system is a transport belt system having at least one endlessly revolving transport belt. The driver roller is mounted such that path spacing between the roll body roller and the driver roller are set to the length of the blanks.

Abstract: In order to prevent the tracks of ancillary substance from smearing when cutting a material web along predetermined cut progressions that lie between raised tracks of ancillary substance relative to the plane of the material web in the direction of a cutting roller, the web can be cut into segments with a predetermined segment length along the cut progressions by a cutting device. The device has a cutting roller, the angular velocity of which can be adapted to the web velocity for cutting the material web, and which can be accelerated and/or delayed between two consecutive cuts.

Abstract: An electric motor having an external rotor, an armature shaft passing therethrough, and an internal stator surrounding the armature. The armature is coupled to the stator by a rolling bearing. The improvement comprises the bearing as a double-rowed radial bearing having a common outer ring within the bore of the stator, first and second races, spaced from one another and adapted to receive first and second rows of rolling elements, and first and second inner races worked directly into the armature shaft.
