Abstract
A movable folder assembly includes one or more folders slidingly supported on a pair of rails and an actuator for moving the folder on said pair of rails. The actuator may include a hydraulic cylinder and a control unit for controlling said hydraulic cylinder. The folder(s) is supported on said rails by bearings. Preferably, the bearings are linear bearings, and most preferably, the folder(s) is supported on at least one of said rails by dual-type linear bearings. The folder(s) may be used in conduction with a former board arrangement in a web-fed rotary newspaper printing press which includes a first and a second row of former boards each row including a first, second and third former board for longitudinally folding one or more ribbons passing over the former boards. The first row of former boards is arranged above the second former board, and a movable folder is located below one of the former boards of the second row of former boards for crossfolding and cutting the ribbons into signatures.
