Patent number: 5617789Abstract: A printing press is provided with at least one counterpressure cylinder and with at least one printing roller cantilevered at one end in the rolling stand and at least one inking roller or screen roller of an inking system cantilevered at one end in the rolling stand, where the bearings of the printing roller and screen roller travel, in guide mechanisms, relative to the counterpressure cylinder. In order to ensure that the printing executed by means of the end region of the cantilevered impression cylinder is also perfect, a plate is coupled to the rolling stand, which plate is provided with bearings in order to accommodate the journals of the free ends of the printing and screen rollers. In this regard, the plate can be swung to either a retracted position, in which the cantilevered rollers are freely accessible, or to a operating position, where the journals of the free ends of the rollers are carried by the plate.Type: GrantFiled: April 18, 1996Date of Patent: April 8, 1997Assignee: Windmoller & HolscherInventors: Fritz Achelpohl, Uwe Rogge, Alois Thole, Rainer Jendroska

Patent number: 5275656Abstract: The invention refers to an apparatus for applying liquid media onto a web with an applicator roller carried in a machine frame and an impression roller which can be lifted thereoff and adjusted thereto, said impression roller forming a roller gap with the applicator roller, through which the web passes. For the solution of the problem to provide an apparatus with a simple and robust design, in which a desired gap between the impression roller and the applicator roller can be easily set, the impression roller is mounted between the one arms of two parallel two-armed levers being pivotably supported in the machine frame. At the ends of the other arms one end of a pressure piston cylinder unit pivoting the two-armed levers is coupled, the other end of which is mounted in the machine frame. Furthermore, at least one stopper is provided which is allocated to one of the lever arms, arranged in the machine frame, adjustable as to height, and by which the width of the roller gap is limited.Type: GrantFiled: May 15, 1991Date of Patent: January 4, 1994Assignee: Windmoller & HolscherInventor: Rainer Jendroska
