Abstract: This invention concerns a sheet guide unit which allows sheets of thinner sheets to be conveyed in a stable fashion when the sheet is conveyed in a sheet guide space between the printing cylinder and a sheet guide surface. The sheet guide unit has 1) a first air control means to control the supply air, which is blown from the air supply chamber through air vents provided in the upstream portion of the path, and conveys the sheet through the sheet guide space suspending over the downstream portion of the path; and 2) a second air control means to control the aspiration air, which is drawn into the aspiration chamber via a plurality of first aspiration vents in the downstream portion of the path, and exhausted from an aspiration port provided on one of the walls of the aspiration chamber.

Abstract: The present invention relates to an ink supply device and an ink key thereof and makes it possible to stabilize the action of the ink key and to save labor in cleaning of the ink key by preventing the ink from getting into a gap between the neighboring ink keys. A cover member hermetically covering the surfaces of a plurality of ink keys is mounted in an ink box to reduce an area where the ink keys are in direct contact with the ink and a groove is made on one or both of the sides of each of the plurality of neighboring ink keys covered by the cover member from the top surface of the ink key to the bottom surface thereof, and even if the ink leaks and gets into a gap between the ink keys because of capillary phenomenon, the groove prevents the ink from spreading the gap between the ink keys.

Abstract: The present invention provides a method for operating a sheet-fed offset press so as to reduce the occurrence of spoilage caused by nonuniform printing. In this method, the timing of start of oscillating motion of oscillating rollers is regulated. Also, the present invention provides an oscillation mechanism for a sheet-fed offset press, in which less failure and wear occur, and a smaller force is required to accomplish a changeover from transmission to stoppage of oscillation and vice versa.
