Description

Device for dyeing film tapes. The invention extends to an apparatus for dyeing film tapes using a number of the Color liquid receiving individual containers, over which the film tape lies and for For the purpose of staining is sunk as required.

Compared to the known dyeing devices belonging to the same genus the subject of the invention differs in that the paint containers are small, Trough-like boxes are formed, over which the tape runs stretched out and by pressure pieces acting from above for the purpose of inking through as required is sunk, so that the film tape the relevant ink fountain under the pressure piece pulling away, going through in an immersion loop.

The small amounts of color are advantageously combined with a special one Paint container connected by a circulation line through which the paint liquid in constant circulation for the purpose of renewal and mixing from the trough to the paint container runs.

In the drawing, the dyeing device is in a schematic representation shown in an exemplary embodiment.

Figs. R and a leave the staining device in side and front view recognize, while Fig. 3 and 4 one of the trough-like paint boxes used show in side view with sunk and swung thrust pieces and Fig.5 the connection of the trough-like paint box with an additional paint container shows, both of which are in communication by a by-pass line.

3, 4, 5 and 6 are small, trough-like paint boxes arranged next to each other, about the the film tape 2 coming from the bath i is transported away in a stretched manner will.

Behind each paint tub there is an underside that can be swiveled on an axis Spring action standing folding lever i i arranged with a cross star-shaped Pressure pieces 7, 8, 9, i o is equipped.

Each of these folding levers il can counter the spring action swinging it open if necessary, folded down onto the film tape from above, thereby inserting it into the associated Paint trough be sunk so that it is the same in an immersion loop for the purpose Coloring passes through.

By acting on the front end of the folding lever i i, on the trough head provided locking spring 13 under which the lever snaps when folding down, is the same held in the immersion position according to Fig. 3.

After releasing the locking spring 13, the lever i i is free and oscillates automatically returns following the spring action (Fig. 4).

The pressure pieces 7 to io are at their acting against the film tape Edges with a protective covering (suede cover or the like.) Equipped, while the Edges of the paint troughs at the overflow point of the film also protective covering own.

By folding down the lever i i with the pressure pieces, the film tape be quickly switched into the dye liquid at the given time, while the interruption of the dyeing process by releasing the self-springing lever. can be just as sudden.

The cross-star-shaped pressure pieces on the lever i i have four Work surfaces and are adjustable with respect to the lever, so that after the wear and tear of the Protective covering on a pressure point another work surface in working position can be screwed in and comes into effect.

So that the coloring liquid in the small coloring troughs 3, 4., 5, 6 is constant is renewed and mixed up, each trough is expediently through a Z, Tmlaufleitung 14, 15, 17 connected to a special paint container 16, from .which means Pump 17, the color liquid is conveyed in the circuit to the color trough 3 to of this through the overflow pipe 1.4 through the intermediary of the equipped with a filter screen Funnel inlet 15 again (to flow back into the container 16 (Fig. 5).

If several color troughs are filled with the same coloring liquid, they can be fed from a common paint container 16, either two separate circulation lines are used or the color liquid only through a feed line is brought into one container, which is connected to the other container, which in turn has the overflow line, connected by a connecting pipe is.

Claims (5)

PATENT CLAIMS: i. Device for dyeing film tapes under Use of a number of individual containers holding the color liquid, over which the film tape lies and is sunk as required for the purpose of inking through, characterized in that the paint containers (3 to 6) are designed as trough-like boxes are, over which the film tape (2) runs stretched and by acting from above Pressure pieces (7 to io) is sunk as required, so that the band, the switched on Pulling paint box under the pressure piece, runs through in an immersion loop. 2. dyeing device according to claim i, characterized in that the color troughs (3 to 6) connected to special paint containers (16) by a circulation line (14, 15, 17) are and from these through the circulation line constant influx and renewal of Color liquid obtained. 3. Dyeing device according to claim i and 2; characterized, that with each paint tub (3 to 6) a spring-loaded one, from top to bottom the film tape (2) foldable rocker arm provided with a pressure piece (7 to io) (ii) is arranged, which after folding down by a locking spring attached to the trough (13) is held and swings back automatically after it has been triggered. Dyeing device according to claims i to 3, characterized in that the Pressure pieces (7 to io) and also the edges of the paint troughs at the overflow points of the film tape are provided with a protective coating (suede cover or the like). 5. Dyeing device according to claim i to 4, characterized in that the rocker arms (i i) seated pressure pieces (7 to io) designed like a cross star and convertible to the Levers are attached.
