Impregnation device for wide goods, especially for textiles

The impregnation of textile wide goods with dye, bleach or other treatment liquors are carried out by passing the goods through the liquor with subsequent squeezing between elastic malts. Most famous are for this Purpose foulards.

The less liquor, the better the impregnation device is contained in the apparatus, the more the liquor penetrates the fabric into the innermost fibers, the less it is Oxidation of the liquor is and the more evenly the excess liquor is squeezed off.

The invention provides a new type of impregnation device created, through which the first-mentioned conditions are met in an even more favorable manner than before. According to the invention this is achieved by keeping the goods short

in front of the passage of the squeegee rollers a very narrow, vertically arranged flat container with little space runs through, into which the liquor is constantly pumped and the one at the top with a funnel-shaped Extension and at “each older open end with two elastic Lips closed.

According v / Eiterer invention will be further reduced, the content of Plachbehälters by ^f since, 5 a, preferably made of Teflon sheet and the respective V / arenbreite adapted bag is hung in it, which passes with its lower open end by aen pneumatic closure and thereby is closed by the elastic lips, together with the continuous width, liquid-tight,

Reference is made to further features of the invention in the description of the exemplary embodiment shown in the drawing.

As the drawing shows, is at a low level above the gap of the two squeegee rollers 6 and 7 of the flat container 1, which has only a small inside width, is arranged on its upper side is provided with a funnel-shaped extension 2. The container has at its lower open end on each wall over its entire length an elastic lip 3 * which runs the container together with the vertical dvtrc Wide goods sealed in a liquid-tight manner.

The sealing lips are coated with Teflon to reduce the friction on the passing goods. The sealing lips 3 can also be designed as pneumatically or hydraulically inflatable tubular metal tubes, v / o be facilitated by drawing in goods and cleaning the flat container. The liquor is continuously pumped into the flat container 1 by a liquor pump 11 via a line 12.

BelmDirection of the excess impregnated goods through the In the nip of the nip rollers 6 and 7, a liquor wedge 8 is formed, which closes on both sides via funnels 9 a small standing vessel 10 runs off.

The advantage of this arrangement is that when possible Flat design of the flat container of the liquor contents very much What is slight is that the goods with liquor penetrate the goods well on the long way when passing through the flat container takes place, and that when the goods pass through the nip rollers, the liquor is sufficient to the innermost Fibers being squeezed. Due to the elimination of pulleys and displacement bodies running under the fleet level the facility is also structurally and operationally simplified and thus compared to the known impregnation facilities significantly cheaper.

When processing goods in a wide variety of widths, it is proposed according to a further invention, the flat container

to be designed for the largest goods width, but preferably off when driving narrow goods into the flat container Teflon foil to hang in the pocket 4 open at the bottom, which is only as wide as the goods just treated. Here the pocket is so long that the ends open at the bottom pass between the Schlaumhmembranen J and at Inflate the same to be sealed together with the goods passing through. Suffering from the execution in Teflon the passing through '..are only a very low friction.

The constant supply of dye liquor takes place in such a way that the individual components of the Liquor are pumped to the jar into which the superfluous liquor, squeezed off by the squeezing rollers, also runs. Since the squeezed-off liquor has already come into contact with atmospheric oxygen and is also slightly foamed, it is through the smallest possible formation of the jar to ensure that this proportion of liquor by mixing is constantly used up with the fresh liquor.

The liquor level in the upright container can be automated by a pressure sensor with contact 14 the Promotion of the metering pumps 13 is regulated automatically.
