In FIG. 5, the exemplary embodiment of FIG. 3 is shown once again in the schematic diagram. Here will It is clear that the media reservoirs 41, namely the main supply pipes, have a large number of solenoid valves 60 are assigned over their entire length, all via the outlets 341 with the media reservoirs 41 are connected, each solenoid valve preferably having its own outlet connection 341. Every solenoid valve 60 is then in turn, as can be seen from FIG. 3, connected to the inflow lines 45, which are not in FIG. 5 are visible.

In Fig. 6 an embodiment with a rotating tape template is shown, also shown and described in DE-AS 25 43 394 of the applicant. The band template runs over partially driven rollers 54, 55, 56, one of which can be designed in a manner known per se as a tensioning and regulating roller. Here, too, is the media feed device 4 is provided with a sliding shoe 244 and has feeds to the media reservoirs 41. There In this exemplary embodiment, too, an axial back and forth movement of the media feed device 4 is made possible is, the claw 146 is shown and the supply lines to the media reservoirs 41 are, as in other exemplary embodiments, each preferably flexible hoses.

In FIG. 7, an embodiment is shown in which the media reservoirs 41 are square in cross section and the solenoid valves 60 actuate air cylinders 62 with pump-like plungers 162 at the end of their piston rod work together. The plungers 162 are moved back and forth by actuating the air cylinders. These are in Sleeves 63, which carry passage cross-sections 163, so that when the plunger 162 is turned up and down, the passage cross-sections 163 are closed once and then reopened.

In FIG. 7, three passage cross-sections 163 are closed, while one is open. With the passage cross-section open 163 the application medium arrives in the direction of arrow G into the associated inflow line 45 and from here into the Collection slots or chambers 144.

Fig. 8 shows that the inflow lines 45 also directly in the lower rounding 40 of the sliding shoe 244 can open. The air supply takes place in the exemplary embodiment in FIG. 7 and 8 via air lines 64 which extend over the length of the media supply device 4 and from which lines 164 are led to the solenoid valves 60.

In Fig. 9 this system is shown again schematically. The air cylinders 62 are only indicated as lines and the position of the solenoid valves 60 is only indicated. The figure only shows that a large number of Air cylinders 62 are assigned to the media reservoirs 41. The assembly can be done much closer than in Fig. 9 shown, namely the air cylinders 62 can stand close together, but this cannot be realized in the drawing, if you want to leave this in a certain clarity.

Possible embodiments of the collection slots 144 or collection chambers are shown in FIGS. 10, 11 and 12.

The mode of operation of the devices shown is that, due to the arrangement, only a few media reservoirs 41 in the interior of the media supply device, for example, only two, three or four main supply pipes as media reservoirs 41, for example, paint is brought by the pumps 42 over the web passage level, and the outlets 341 of the media reservoirs 41 are optionally opened and closed by the solenoid valves 60, what can be caused by the control unit 66,

which is electrically connected to the solenoid valves 60. This can be a program control, but control can also take place directly from a drawn pattern. Such controls are known, for example, from board controls for weaving or knitting machines. Depending on the position of the respective solenoid valve, the inflow line 45 is opened or closed or are actuated the plunger 162 which, for example, drive paint into the inflow lines 45, whereby the application medium reaches the collecting slots 144 or collecting chambers or is driven directly out of the inflow lines 45 will. The media outlet area therefore either consists of the ends of the inflow lines 45, each of which are assigned to one another or from the collecting slots 144.

The advantage of the device is that it is programmed A certain liquid emerges directly in the media outlet area and reaches the material web, either directly or through a screen printing stencil or through a partial stencil. The Media outlet areas are each offset by relocating the media supply device 4, namely the work or order bar. It is essential that everyone Media outlet area 44 or it will mostly be collecting slots 144 or collecting chambers that are open to a template or to the goods, are equipped with a valve, which on all available media, for example Colors, programmable or determinable or switchable or switched on at any time is. Each of the individual openings, namely the inflow lines 45, has such a valve, the colors or the like. from the media reservoirs 41, that is to say the main supply pipes, to each of the individual valves by means of hoses or other facilities. As a magnet

valves, multi-way valves can be provided which are provided with the media or paint connections and which are freely selectable switchable via remote-controlled means on different feeds. As a media feed device work bars or order bars will generally always be used and as media reservoirs in general main supply pipes, with more than two media reservoirs in the media supply device 4 should be ordered.

In the illustrated embodiments, 4 media reservoirs 41 are shown, which are used as the main supply pipes are drawn through the working beam, since the illustrated embodiments are essentially is intended for the application of colors and when applying colors in general by four-color printing is assumed. Accordingly, the arrangement of four main supply pipes is extremely advantageous because You can use this to apply a very wide range of shades to the goods, practically all shades of color.

Whether the normal outflow of the media from the media reservoirs 41 is now being used, with this below constant controllable pump pressure, or whether the medium is now actively driven out by means of Air cylinders 62 made by supplying compressed air through lines 262, 362 from the solenoid valves are controllable from is irrelevant. Instead of the air pressure cylinder, hydraulic cylinders can of course also be used Find use.

When multi-way valves 160 are arranged as shown in FIG. 7a, these are placed between the main supply pipes trained media reservoirs 41 set and are connected to all main supply pipes

and connected to an inflow line 45 and can alternately the flow of the media or the colors kXHXXEtex release · The advantage of an embodiment according to FIG. 3 with an arrangement of simple solenoid valves 60 and arrangement a number of inflow lines 45, each only one Lead medium consists in that 144 colors also run from all four inflow lines 45 to a collecting slot can, so that there are 144 mixed colors in the collecting slot. Three colors can be supplied be, two colors or even just one, it doesn't matter. If multi-way valves are arranged according to FIG. 7a and assigned to the main supply pipes, the inflow can generally only take place from one main reservoir 41, unless very complicated multi-way valves are used.

As already mentioned, the concept of the invention is not limited to the illustrated embodiment. So are the most diverse variations conceivable and possible. The media feed device 4 can be designed as a reciprocating Work or order bars work, but can also be designed to be stationary, with or without a template to be worked. The media reservoirs 41 can be designed as main supply pipes and extend over the Extend overall width, but can also be containers, they can be under pressure, under controllable Pump pressure or not. The medium can be expelled actively or by simple physical flow pressure or also by pumping pressure.

It is also essential that in the axial direction of the media feed device, which can be designed as a working bar, the media outlet areas are lined up linearly are always groups of inflow lines or only a single inflow line 45 a media
