A single motor drives the folder and sealer stations as well as a feeder station. Drive trains for the sealer and folder stations are on opposite sides of the machine. A bearing mechanism enables any folding roller to be removed from the machine without removing any other roller and without affecting the machine side walls.

The product parts (30, 30') are especially suitable for a further processing by collecting or inserting because they can be opened easily in the middle. The increased stability of the product parts in which the individual sheets hardly shift relative to each other also have advantages when collated.
