Arrangement for a used for printing and duplicating

machine

The invention relates to printing and duplicating machines, in which the printing ink is fed into a narrow gap is that between the surface of a first, of several The machine's ink rollers and an ink knife are formed is, the edge of which runs along the inking roller surface. During operation, the printing ink is measured through this gap and applied to the roller surface and then applied conveyed to the point where they will be applied to the sheet to be printed or reproduced ** the should. In the following, these machines will be referred to as so-called "machines of the type described". Typical Examples of machines of the type described are offset duplicating machines and some types of printing presses.

So far, the often very viscous printing ink has become that

by the color knife delimited gap of the machines of the described type passed through a dye bath, which in the elongated, container-like space between the surface of the first inking roller and the adjacent surface of the ink knife is formed · This space is called the "ink source" of the machine known and is referred to as such in the following, usually adjusting screws are connected to the ink knife, through the the edge of the ink knife relative to the surface the first inking roller and thus the width of the gap of the ink knife at various points along its length as desired Way can be adjusted to the pull of the inking roller. led to control amount of paint "

With continued exposure to the atmosphere, the Druoker colors are dried or contaminated, which is why the dye * · The source must be cleaned of paint after its daily use if the machine continues to work properly target. On the other hand, the cleaning of the inking rollers following the already mentioned inking roller is not necessary as often, as these rollers only carry a thin layer of paint · When a slow drying paint is used and the machine is often in use, these rollers only need to be cleaned at long intervals or when the paint is contaminated will. Nevertheless, the daily removal of the Remaining paint from the paint source is a time-consuming and unpleasant job, which is why it is the most urgent task

009849/0045

the invention is to provide means to avoid this.

The present invention relates in principle to the supply of a machine of the type described above with printer color, the color not being input directly into the color source in order to, as before, be on one side of the first To form the open "ink bath" located in the ink roller, but rather is conveyed into a container that is detachably connected to the machine and which, if necessary, has a fixed or easily removed container. forms removable part of the machine, and means for exerting a pressure on the ink located in such a container, whereby the ink is gradually displaced from the container and in gauged quantities on an ink roller can be applied to the machine

The invention thus creates a container which can be filled with printing ink for ink rollers and which is detachable on a Machine of the specially designed level type is attached, the «ine has elongated lip which between the container and the surface of the ink roller a measuring the amount of ink Gap creates one or more outlet openings in one Contains container wall and which is provided with devices or can come into operative connection with devices If a pressure is exerted on this ink, the ink emerges from the container through the outlet opening or openings

009843/0045

to enable the surface of the roller located in front of the gap · The paint container according to the invention faces opposite the above arrangements have two major advantages. On the one hand, the container can be designed in this way be that it can be easily attached to and removed from a machine without an operator must operate, which can be soiled with paint. On the other hand, the container can be constructed so that the Color both in the container and when it is being conveyed from the container to an adjacent inking roller is essentially out of order Contact with the atmosphere. As a result, the container can remain on the machine for a period that is practical is only interrupted by the periodically recurring need to clean the inking rollers of the machine, whereby there is no need for daily cleaning of the machine Ink roller even then leads to an adequate supply of ink to the roller over its entire length, if - how this is often the case in practice - that of the roller absorbed color varies significantly along the length of the inking roller. A waste of color is almost completely avoided, because the entire amount of paint is actually used up. A daily removal of the color from the coloring source on the other hand, leads to significant waste.

A preferred exemplary embodiment according to the invention provides a container which is of such a cheap nature

A second embodiment of a mounting device according to the invention, shown in FIGS. 14 to 16, is similar in FIG many aspects of the holder shown in Figures 8 to 13, which is why parts corresponding to one another have the same References are provided without them being used in the following to be mentioned in more detail

The only important difference between the two devices lies in the design of the drive mechanism of pusher 30. So, as prepared, the Push-button of the first mounting device is driven by a spring motor which contains a single helical spring. The-

This arrangement, which is quite well suited for many purposes, has the peculiarity that the force to push out the paint from the container cannot be varied depending on the viscosity of the paint. However, this would be very desirable when in a particular machine different colors with very different viscosities should be used. Therefore in the device after 14 to 16 provision has been made for a large available printing area in which a total of seven separate Springs 104 to 110 are provided, which act on the pusher 30 individually or in any combination that can be predetermined can"

The springs 104 to 110 are evenly coiled ribbon springs, which are wound on sleeves that rotate freely around the shaft, with the free end facing away from the sleeve each spring is clamped between two stiffening plates 111, in which a vertical pin / 112 is additionally attached. Each spring can slide freely between an upper and a lower leg 113 and 114, which correspond to the ends of the rack 29 are screwed, the pins 112 being able to engage the rails when the springs are seen from their fully extended position Move position to the right (see Figure 15) · By engaging one or more springs in the rails 113 and 114 become the rack and thus also the pusher 30, as can be seen in Figure 15, pushed to the right, so that, as already described, squeezed paint out of the container
