* The invention relates to a device for long-term wet treatment of textile fabric sheets, which are characterized is, ofaß it several arranged in a common frame, coupled to one another and with the Having vats filled with treatment liquid for the tissue; that the fabric is driven by an impregnation rollerxi arranged in each unit by the running speed Moved on at a certain speed so that the web of fabric is used to duration in the treatment liquid and for suitable soaking or impregnation inside; fedes with Liquid-filled vat remains without movement and that the fabric is successively passed through impregnation rollers run wira,

The device according to the invention represents an essential innovation and opens up the possibility that the web of fabric remains immersed for exactly the time required for the intended treatment. this happens automatic, safe and highly effective.

For a better understanding, the device is according to • the invention explained in more detail below with reference to the embodiment shown in the drawings.

Show in detail:

Pig. 1: a schematic side view of a device according to the invention; and

Fig. 2; a further schematic side view of a device according to of the invention in a different work cycle

As can be seen from the drawings, the device according to the invention includes a number of interconnected coupled tubs 1, which are filled with the respective treatment liquid for the fabric web. The respective The fabric web moves at a speed due to the circulation of motor-driven feed rollers 2 specific speed forward.

Bm must extend the length of time the respective fabric web remains in the liquid and in order to achieve adequate or impregnation, it is necessary _t 4ai the fabric web remains on its way in the liquid and is allowed to run several times in succession through impregnation rollers 5.

To this end, leads to hasten © Text !! woven web loose or flabby au and confirms the Iieprägnierwalaen J> using a fork 4 at the Hubendpunkten in two (different) Drehriciitungen that Impyagnierwalaen ie 5 »grounded in"

Reaching the stroke end position reversed.

In this way, the fabric web has both on entry (into the vats) and on exit (from the Vats) a smooth and uniform movement. So that the · tissue webs in the treatment liquid in To remain looser, looser Eorm, the fabric web can be subjected to a backward movement determined by the rotation of the impregnation rollers 3 To give. Every time the fabric web is stretched and the fork 4 lifts, the impregnation rollers change 3 their direction of rotation. This gives the web of fabric a forward movement until it tightens and the Fork 5 lifts, which in turn results in a reversal of the direction of rotation. i

About possible differences in length from those in the vats A device 6 is provided, which consists of a (compressed air operated) Air switch and a corresponding pressure roller actuated roller carrier lever consists.

This lever carries a fork 7 in which the fabric web runs. When lifting the roller, the fork follows it, so that ßie releases the fabric web from the frictional engagement and thus the fabric web in the rest position without any further forward movement brings.

The individual roller units 3 are supported by the fork 4 or 5 controlled. This makes it possible for one of the rollers to rotate in one direction as much as the other rollers rotate in the opposite direction;

The individual roller units 3 are (further) through Shafts driven, which cause their opposite rotation. Such an arrangement can be used for calibration an aging wet treatment of fexbil tissue. "in continuous process run with suitable I * embossing

Achieve nation of the fabric webs.

Bs should also be noted that the device according to of the invention, of course, the most diverse Changes can be made, provided that the intended Purpose-serving features or facilities are not impaired.
