ABSTRACT:
To be able to produce an accurate second lengthwise fold on printed copies delivered by a web-fed rotary printing press, a second group of folding cylinders is provided downstream of a first group of folding cylinders, with the axes of all cylinders of both groups being parallel to each other. A conveying mechanism is provided between the two cylinder groups, which is equipped with turning devices by which the printed copies transferred from the first cylinder group by means of strip lines are nipped and turned through 90.degree.. Further strip lines are provided for transferring the turned copies to the second group line of folding cylinders.
