    摘要： A simple mechanism is provided for adjusting a print pressure and for moving a plate cylinder relative to an impression cylinder w ile preventing a change in a contact pressure between the plate cylinder and an anilox roll 41. A pair of supporting shafts 5, 6 is opposed with each other across a web 2. A plate cylinder sleeve 7 and an impression cylinder sleeve 8 are detachably attached to supporting shafts 5, 6 different from each other. An ink supply device 40 includes an anilox roll 41 and is moved in alignment with a position of the plate cylinder sleeve 7 attached to a supporting shaft 5 or 6. A turning body 50 holds one of the pair of supporting shafts 5, 6 and is turned together with one supporting shaft 5. A center of rotation 43 of the anilox roll 41 is matched with a center of turning 51 of the turning body 50, when the ink supply device 40 has been moved in alignment with the position of the plate cylinder sleeve 7 attached to the one supporting shaft 5.

    摘要： The present invention relates to a scraper device for a printing machine which comprises a scraper body (20) having longitudinal blades (2) and lateral sealing elements, and having ink inlet and outlet passages (24). The scraper body (20) is supported by a scraper support (10) adjacent to an inking roller of a printing machine, and having ink supply and discharge passages (11) connected to respective ink supply and discharge conduits of an ink circulation device. Positioning and fixing means allow fixing the scraper body (20) to the scraper support (10) in an operating position in which openings (24a) of said ink inlet and outlet passages (24) of the scraper body (20) are in fluid communication with openings (11a) of said ink supply and discharge passages (11) of the scraper support (10).
