摘要:
An inking system is comprised of rollers. At least one roller has a barrel with at least two separate sections. One of these casing sections is arranged in a manner which permits it to be changed independently of the other casing section.

A printing unit has at least four cylinders that form a printer. At least two of these four cylinders rotate independently of each other. At least one of the cylinders in the group of at least four cylinders has a set up rotational speed that is not zero and that is different from a production rotational speed of that cylinder.

A distributing roller includes a roller sleeve and a gear located on the interior of the roller. The gear generates a rotational speed of a roller inner shaft that is different from the rotational speed of the roller sleeve. A bearing, that is supported obliquely on the roller inner shaft, with respect to the roller axis of rotation, generates an axial travel of the roller sleeve with respect to the roller shaft.

An adjustable bearing arrangement is used for the remote controlled adjustment of an inking roller or a dampening roller with respect to a second, contacting roller. The journal of the roller to be adjusted is secured to an adjusting element. A pre-settable adjusting force is transferred from one roller to the other. In the adjustment position, the receiving element or elements are locked so that it is temporarily impossible for the now adjusted roller to move either in, or opposite to the direction of adjustment.

An inker unit for a printing unit of a web-fed rotary printing press has a pair of ink application rollers in direct contact with a forme cylinder and with a central, ink receiving roller. A pair of inking rollers are also in direct contact with the ink receiving roller, and in indirect contact with the ink application rollers through riding rollers. The ink application rollers are thus inked both directly and indirectly from the ink receiving roller.
摘要:
The tack of an ink that is used in a printing group of a rotating printing press, or the temperature of a rotating component in the printing group is selected or controlled. This selection or control is accomplished in a manner so that optimal printing is achieved.
摘要:
A method for operating a printing group and a device for the use of a printing ink in a rotary printing press is disclosed. The tack of an ink that is used in a printing group of a rotating printing press, or the temperature of a rotating component in the printing group is selected or controlled. The ink itself is temperature regulated in response to production speeds to maintain the ink tackiness in the desired range. A gradient that sets forth an interrelationship between ink tackiness, temperature and production speed can be used in a control device for use in temperature regulation.
摘要:
A pressure force exerted by first and second cylinders upon at least a third cylinder in a printing machine is regulated by a pressure regulating device. The device can also be using for moving a first cylinder and at least one second cylinder into and out of contact with a third cylinder. Actuators, which exert a radial force on a cylinder cooperating with the actuators, are provided. An aperture angle between the radial forces exerted by two actuators on the same cylinder is the same in both cylinders. That aperture angle is independent of an aperture angle formed by the pressure force exerted by the first and second cylinders on the third cylinder.
摘要:
An inking unit for the printing couple of a double width printing press includes at least one roller. The inking unit consists of at least one, and possibly two chamber doctor blades. If there are two such chamber doctor blades, they are positioned side-by-side in an axial direction of the roller and they can operate independently of each other. If there is only one chamber doctor blade, it can have a length sufficient to enable the side-by-side positioning of at least four newspaper pages. The chamber doctor blade or blades can be positioned against or out of contact with the roller.
