ABSTRACT:
Printing products from a printing machine are successively moved one above the other against a stop to form a stack. A leading product in contact with the stop is biased adjacent to its fold by a perpendicular force compressing the fold. A trailing product is moved on the free end face of the leading product and the perpendicular compressing force is substantially relieved upon approach of the trailing product fold to the stop. The trailing product is biased by a perpendicular force in such a manner that the trailing product is pressed adjacent its fold against the leading product. The movement of the trailing product is not hindered by the perpendicular forces and is synchronized with the build up and relief of the perpendicular forces.
