摘要:
Provided is a cylinder device for a printing press, which is simple in configuration, and with which the printing pressure in at least three cylinders can be adjusted in a highly accurate manner. The device is provided with: a collecting plate cylinder (22) supported so as to be capable of moving towards or away from a collecting blanket cylinder (21) and a blanket cylinder (19) ; an eccentric inner metal (42) that rotatably supports the collecting plate cylinder (22), and that by rotating moves the collecting plate cylinder (22) towards or away from the collecting blanket cylinder (21); a hydraulic cylinder (45) that rotates the eccentric inner metal (42) ; an eccentric outer metal (43) that axially supports the eccentric inner metal (42), and that by rotating moves the collecting plate cylinder (22) towards or away from the blanket cylinder (19) ; a drive device (46) for rotating the eccentric outer metal (43) ; a stopper (49) provided to a main machine frame (44) ; and an adjustment bolt (47) provided to the eccentric inner metal (42), for abutting the stopper (49) when the collecting plate cylinder (22) moves towards the collecting blanket cylinder (21).

A variable cutoff printing unit is provided that includes a plate cylinder (54,154), a plate cylinder support (14,14') removably supporting the plate cylinder, a blanket cylinder (56,156), a blanket cylinder support (16,16') removably supporting the blanket cylinder, a frame, the plate cylinder support and the blanket cylinder support being coupled to the frame, a sliding element (32,32') coupled to the blanket cylinder support for moving the blanket cylinder support toward and away from the plate cylinder support, and a stopping device (90,90') for stopping movement of the sliding element to limit the movement of the blanket cylinder toward and away from the plate cylinder to a defined range. A method of operating a variable cutoff printing unit is also provided.

An offset web print unit includes a plate cylinder, a blanket cylinder, the plate cylinder being movable during a throw-off operation, and a tucker bar for tucking plates into the plate cylinder, the tucker bar having an axis movable with respect to the plate cylinder axis for reducing a gap during the throw-off operation. A method is also provided.
摘要:
L'invention concerne une unité (5) d'impression d'une bande de papier (3) comprenant un bâti (15) et au moins un premier et un deuxième groupes d'impression (7A, 7B), chaque groupe d'impression (7A, 7B) comprenant un cylindre porte-blanchet (9A, 9B) et un cylindre porte-plaque (11A, 11B), l'unité d'impression comprenant également un mécanisme (13) de support et de déplacement des cylindres grâce auquel l'unité d'impression (5) présente au moins une configuration en-pression, dans laquelle les cylindres porte-blanchet (9A, 9B) sont appliqués l'un contre l'autre et contre les cylindres porte-plaque (11A, 11B), et une configuration hors-pression, dans laquelle les cylindres porte-blanchet (9A, 9B) sont espacés l'un de l'autre et espacés des cylindres porte-plaque (11A, 11B). Le mécanisme de support (13) comprend au moins un premier système (27) de renvoi de la masse d'au moins un premier cylindre (9A) du premier groupe d'impression (7A) vers un premier cylindre (9B) du deuxième groupe d'impression (7B) et inversement, de sorte que les premiers cylindres (9A, 9B) forment contrepoids mutuels lors du passage de l'unité d'impression entre ses configurations en-pression et hors-pression.
