Abstract: A sheering device (1) for routing folded fascicles (2) advancing on a path through a printing line onto one or more than one collecting device (20) comprising a comb-shaped sheerer (3) adapted to assume a raised position and a lowered position with respect to the advancement path of fascicles (2), two or more than two cams (5) connected to the comb-shaped sheerer (3) which raise and lower the comb-shaped sheerer (3), and one or more than one motor (7). The one or more than one motor (7) is adapted to automatically select one of the two or more than two cams (5) and drive the selected cam (5) according to the upstream advancement speed of a folding machine (9) which folds the printed material into fascicles (2). In a preferred embodiment, at least one of the two or more than two cams (5) is adapted to realize at least two operating ratios.

Abstract: A “spider” device for collecting and conveying signatures produced on rotary print machines. The inventive device is adapted to be moved outside the production line without stopping operation of the production line. The device is equipped with a hinging mechanism adapted to connect it to a vertical riser of the production line for rotating it around at least one vertical axis with respect to the ground. The inventive device is further equipped with a hooking/unhooking mechanism used to allow repositioning the device in the same operating position in the production line.

Abstract: A “spider” device (1) is disclosed for collecting and conveying signatures produced on rotary printing machines; such device (1) is movable, namely it is adapted to be moved outside the production line (5) without stopping it; for such purpose, the device is equipped with hinging means (6′, 6″) that connect it to a vertical riser (9) of the line (5) for rotating it around at least one vertical axis with respect to the ground, and it is further equipped with hooking/unhooking means (14) to the production line (5).

Abstract: Arrangement for automatically introducing paper ribbons into a plurality of angle-bars of a printing press, comprising a plurality of endless chains, one for each angle-bar, for conveying a respective ribbon to a folder-stitcher unit. Each chain has a gripper for grasping a leading end of the respective ribbon. Each chain is independently driven by a motor drive.

Abstract: Apparatus which applies staples to groups of sheets at the discharge end of a rotary printing press has a rotary conveyor which transports the groups of sheets past a stapling station where the groups are provided with pairs of staples. If one of the two regular stapling units is out of commission, an auxiliary stapling unit is started in response to detected absence of two staples in each finished product so that the groups of sheets receive pairs of staples while the defective stapling unit is being inspected, repaired or replaced.
