Abstract

An apparatus for slowing down products in the folder of rotary printing machines. A product-directing system is arranged between the jaw cylinder and paddle wheel, and a driven decelerating-roller pair is integrated into the product-directing system. In order to provide an apparatus which can be adjusted in a straightforward manner and ensures that the products are slowed in a functionally reliable manner upstream of the paddle wheel, the circumference of the decelerating rollers is equal to at least one product length, and the decelerating-roller pair is driven at a non-uniform speed.
