摘要:
Printing units are supported between side frames of a web-fed rotary printing press. Each such printing unit includes at least one transfer cylinder and at least one cooperating printing cylinder, which is embodied as a forme cylinder. These cylinders are rotatably mounted between the spaced side frames. The printing unit is provided with an inking unit that includes a roller.
摘要:
Printing groups are each comprised of at least two cooperating cylinders, each of which is mounted in a bearing unit that radially displaces its associated cylinder. At least one of these bearing units is provided with an actuator which is controlled, or regulated by a control unit. An inking unit, which encompasses at least one ink application roller, is provided for each printing group. At least one of the cylinders of the printing group, and an ink application roller of the associated inking unit can optionally be placed against each other. A dampening unit, comprising at least one dampening fluid application roller, is also provided. At least one of the cylinders of the printing group and a dampening fluid application roller of the dampening unit are also optionally placed against each other. The at least one actuator for the bearing unit is remotely controlled and is embodied either as a hydraulic actuator or as a pneumatic actuator.

摘要:
A printing blanket or dressing includes a dimensionally stable carrier plate which has ends that can be secured to a transfer cylinder. A coating is applied to the carrier plate and forms the lateral surface of the transfer cylinder. A recess is located in the printing blanket or dressing intermediate the ends of the blanket or dressing.
摘要:
An adjustment of a transfer of printing ink is accomplished by arranging a first roller in an inker unit and by using that first roller to transfer ink to a forme cylinder. A temperature is adjusted on an outer surface of the first roller by the use of a first temperature control unit which includes an adjuster device. The adjuster device also adjusts a temperature to be set on an outer surface of the forme cylinder by the use of a second temperature control unit. These two temperature control units adjust parameters of the printing ink through the controls of the outer surfaces of their associated first roller and forme cylinders. The parameters of the printing ink which are adjusted are preferably the ink's tackiness and its viscosity.
摘要:
The contact pressure between an adjustably mounted first cylinder and a second cylinder in a printing machine, and particularly in a web-fed printing machine can be adjusted. An actuator is usable to force the first cylinder toward the second cylinder with an adjustable force. A fixing device is usable to fix the first cylinder in a desired position relative to the second cylinder.
摘要:
A dryer is used for drying a web of material. The dryer includes a passage duct for the material web. Drying takes place within this passage duct which includes at least one straight section. The dryer is disposed on a printing group which includes vertical web guidance. The passage duct straight section is essentially horizontal and receives the web of material delivered to it by the printing group. The passage duct is comprised of at least two sections through which the web of material travels in opposite directions.
