A cut-off register controller is usable in a longitudinal fold forming assembly of a rotary cylinder printing press that is provided with at least one form folding assembly plane which consists of two adjacently defined longitudinal fold formers. The web ribbon or the partial web ribbons, which are longitudinally formed and folded by the formers are collated at an exit of the former assembly by the operation of a roller pair and are formed into a combined ribbon. That combined ribbon is then fed into a folding apparatus. A number of control circuits are located downstream of the formers and corresponding, in number, to at least the number of formers. The control circuits are usable for controlling the cut-off register of the printed web. Each control circuit has at least one detector and one adjusting member which is usable to adjust the distance between the web or stand and the former.
