摘要： An apparatus and a process are used to maintain a set contact pressure per defined width of a roller mark of an ink application roller against a printing cylinder. The ink application roller is supported by a lever that has one portion biased against an adjustable stop. A temperature compensating element is provided between the lever and the stop to maintain the set contact pressure over a range of temperatures of the ink application roller.

摘要： A flexographic printing press is comprised of at least four printing cylinders which are each driven by a respective drive motor. These at least four printing cylinders cooperate directly with a common satellite cylinder during the printing of a web of material. Each of these printing cylinders supports at least one flexographic printing plate. Each end journal of such printing cylinder is mounted in at least one linear bearing that is located on a lateral frame, and which can be moved perpendicularly to the axis of rotation of the respective cylinder. A stator of each driving motor can be moved along with the associated linear bearing, or along with the printing cylinder. Each such drive motor is configured as a synchronous motor which is excited by a permanent magnet. An independent hydraulic actuator is assigned to each printing cylinder, to change the position of that printing cylinder. At least one linear bearing is arranged in a bearing unit which is placed on the interior wall of the respective lateral frame. The journals of each printing cylinder do not penetrate the lateral frames.

摘要： A doctor blade system utilizes a lightweight doctor blade chamber to apply ink to an inking roller. The doctor blade chamber is removably positioned on a support plate which is, in turn, carried by linear guides on pivotable end plates. A rigid box beam is also attached to the end plates and is spaced from the support plate. A plurality of membrane cylinders are mounted on the rigid box beam and engage a surface of the support plate opposite to the surface that supports the doctor blade chamber. Through the application of suitable force, the support plate and its supported doctor blade chamber can be moved, by sliding motion on the linear slides, into uniform engagement with the surface of the ink roller. The system uses pivotable end plates which are supported by exterior plates that are, in turn, pivotably supported by press side frames. The chamber doctor blade and its support plate and box beam can be moved into several different positions, with respect to the cooperating ink roller, to facilitate doctor blade chamber cleaning or replacement or ink roller replacement.
