The invention relates to a multicolor gravure printing machine, especially for printing on textiles, in which the printing rollers with the associated inking rollers and also the impression rollers on top of each other are arranged.

There are already multicolor gravure presses, at which several pressure rollers are arranged horizontally and one above the other. There is one for each pressure roller Impression roller opposite. Between the pressure rollers

Like any other machine, the gravure printing machines must be cleaned at regular intervals. Depending on the requirements, it may also have to be converted. This can be done by changing the color; rollers, the ink tray and the squeegees happen if a different color is to be used with the same pattern. On the other hand, the printing rollers ^: zen must be replaced if another; Pattern is required. Finally, the impression rollers and possibly also the pressure rollers must occasionally be replaced when the fabric width is changed. The retooling and cleaning of the known machines is very cumbersome and, above all, time-consuming.

The invention has therefore set itself the task of developing a multicolor gravure printing machine that can be cleaned quickly and easily and can be easily converted in a short time.

To solve this problem, the invention proposes that in each case the " Inking roller, the ink pan underneath and the doctor blade combined into one ink unit and all color units one on top of the other in one that can be removed from the machine frame or folded down to the side, frame-like color gate are arranged.

According to a particular embodiment of the invention the ink squeegee of an ink unit is swivel-mounted in the ink tray.

In the subject matter of the invention, the arrangement of a color gate is particularly noteworthy, which has a plurality of color units and both

for example pivotable about a vertical axis is. The inking units themselves consist of an inking tray, an inking roller, a doctor blade and a counter doctor blade, including a device for the squeegee adjustment v lung. ι

The particular advantage of the inventive arrangement The only thing to do is to change the color units and adjust the printing rollers except for "- It is neatly simplified »For this purpose, the paint gate is e.g. swiveled away to the side, whereupon one worker can take out the color units and replace them with new ones, while at the same time another Workers can clean the print rollers properly. Converting from one color to the other therefore happens in a simple manner and with great speed. Also the conversion of a sample to another or the exchange of the impression rollers for a different width of fabric done quickly and easily.

It is also very advantageous that the doctor blade of each ink unit is provided in the ink pan is. The wiped off excess ink from the printing rollers returns to the ink tray, dripping so no longer downwards and no longer contaminates the printing rollers or the underlying pressure rollers whole printing press. The doctor blade is also swivel-mounted in the ink tray. It will be with With the help of a pneumatic cylinder or in some other way before the opening of the ink gate from the printing roller pivoted away and, conversely, pressed against the pressure roller when the arrangement is closed.

The invention is explained in detail below using a drawing:
