Abstract: A rotary press including a plurality of printing groups each with a plate cylinder and a blanket cylinder arranged in the machine frame such that respectively two blanket cylinders are configured to be leaned against each other and, in this way, a paper web that is guidable between the blanket cylinders is printable on both sides. Furthermore, the press includes inking units for inking the printing groups and damping units for applying a damping medium. The inking units are configured such that, with at least some of the inking units, two plate cylinders and thus two blanket cylinders at a time are able to be inked up. In this way, a compact, space-saving and economical design of the press is achieved.

Abstract: A method and equipment for measuring vapour flux from a surface (10) e.g. the rate of water loss from human skin, which is useful in the evaluation of the efficiency of the skin/water barrier. It uses a closed cylinder (12), which is placed against the skin and by measuring the temperature and relative humidity within the cylinder by means of sensors (13, 14) positioned adjacent the wall of the cylinder, the water vapour flux can be determined.

Abstract: A process is provided for preparing a winding roll for a flying roll change by applying an adhesive tape between the beginning of a web and a layer of the winding roll, which layer lies under it. A device is provided for carrying out the process. A device for gripping a part of a material web as well as to a system for gripping a part of a material web is provided as well as a process for gripping a material web. A device is provided for applying a double-sided adhesive tape to a surface as well as to a system with such a device, and a process for applying a double-sided adhesive tape to a surface.

Abstract: Equipment and a method for measuring water vapour flux from a surface such as skin uses a closed measuring chamber in which there is a means for agitating the air within the measuring chamber to give improved measurements.

Abstract: A metering strip for an ink fountain of a printing press for metering printing ink, especially a doctor blade, is fastened in a pivoting mount and has a cylindrically shaped edge with a radius in the range between 0.3 and 1.5 mm. The edge is pressed against an inking roller and forms a metering nip with this roller for the printing ink to be metered. Axial recesses merge on both sides of the metering strip with the cylindrically shaped, wear-resistant edge that covers an angular range of more than 180.degree..

Abstract: The ends of an inking- or dampening-device roller are mounted in respective bearing arrangements displaceable along a control surface co-operating with a guide part. The control surface includes an adjustment zone and a further zone. The adjustment zone runs substantially parallel to an angle bisector of an angle formed by two lines connecting the axis of the inking- or dampening-device roller to the respective axes of the adjacent stationary rollers. Only a single linear drive is necessary for displacing the bearing arrangement.

Abstract: A rotary printing press with rubber-rubber printing units arranged essentially vertically above one another. The rubber cylinders of at least one rubber-rubber printing unit can be retracted from one another in the formation of a usable gap between the two rubber cylinders.

Abstract: The present invention describes a device for moving rollers and in particular rollers of a printing press in two independent directions. Movement in each direction is independent of movement in the other direction. The roller has trunnions which are mounted in roller locks. The roller locks are then mounted on a frame of the printing press. Mechanisms inside the roller lock position the roller lock in one direction with respect to the frame and other mechanisms inside the roller lock position the roller in another direction with respect to the roller lock. This mechanisms are independently controlled and movement of one mechanism is independent of the movement of the other mechanism. By independently controlling these mechanisms the roller can be engaged, disengaged and adjusted with respect to the frame or any components mounted on the frame.

Abstract: A reversible printing unit is equipped with a central distributing roller (9), with which a first transfer cylinder (8) and a second transfer cylinder (12) can be engaged or disengaged independently from one another. A respective dampening mechanism (10) and (24) is associated with each of the transfer cylinders (8) and (12). Depending on the direction of rotation or the mode of operation of the printing unit, the transfer cylinders (8) or (12) and the rollers following them act as dampening rollers or inking rollers. Modes of operation with indirect dampening, pre-inking of the inking mechanism with feed of dampening agent, and rapid and thorough washing of the rollers of the inking and dampening mechanism are also possible due to the independent adjustment of the respective transfer cylinders (8) and (12).

Abstract: The inking device of a printing machine is composed of an inking roller, providing an elastic surface, the inking roller producing a pre-dosed ink layer on the inking rollers. A dosing strip wipes off the pre-dosed ink layer and leaves the quantity necessary for the transfer onto a stereo cylinder, the wiped off excess ink running off freely. For self-cleaning purposes, the dosing strip carries out a movement preferably in the direction of the circumference of the inking roller, so that the area forming the dosing slot which is in contact with the inking roller is continuously modified.

Abstract: A metering blade for zonally metering a liquid film comprises a plate body having a working edge usable in an arrangement in which the setting member bears against the plate body and bridges a portion thereof against a rotating roller comprises a blade with a plurality of zonal setting portions of a material capable of being displaced by resilient flection adapted to be arranged adjacent a setting member which includes intermediate portions between a working edge and the opposite edge compensating for the setting wherein the setting portions are at least 3 mm in thickness and each intermediate portion includes a web part having a thickness which is not more than 1/5th the thickness of the setting portion and has a width amounting to at least five times the thickness of the web. The blade has a working edge with a reinforcement adjacent each web.

Abstract: The disclosure concerns a nine-roll or ten-roll printing mechanism, in which the directions of rotation of the rolls have to be reversed individually according to a printing program. The driving connection to the plate rolls is effected through two oppositely rotating impression roll gears which are rotatably mounted on the axle of the impression roll. The impression roll gears can be coupled to the axle of the impression roll by means of remotely operable couplings. A sliding gear is associated with each plate roll. The sliding gear selectively engages one or the other impression roll gear. An indexing wheel corresponds to each sliding gear and is mounted slidably on the plate roll axle. The width of the sliding gears is selected so that an idling setting is excluded. Each plate roll is connected with its associated offset roll by means of a rotation-secure driving connection.

Abstract: An apparatus for cyclically decelerating and accelerating a ductor roller which has a journal which is mounted on a swing arm for rotation on the arm and is moved with the arm to selectively and alternatively engage the ductor roller with a first roller, such as a fountain roller and a second roller, such as a first roller of a printing press, is employed in inking and damping units of such presses. The apparatus includes a bearing head of the spring arm which provides a rotatable mounting for the journal of the ductor roller and the arrangement includes a planetary gear system connected to the journal and to a free wheel element with a controllable brake acting between the planetary gear system and the bearing head of the swing arm in an arrangement which permits the free wheel element to rotate after the braking system has been engaged to cause the winding or tensioning of a spring, such as a spiral spring, which is disposed between the free wheel element and the journal of the ductor roller.
