and similar tape-shaped fiber material.

Patented in the German Empire on October 11, 1904.

In the currently used processes for dyeing, bleaching, impregnating, drying etc. of card, draw frame, combing machine tapes, cotton wool and similar tape-shaped fiber material makes itself the The fact that the drying of the wet card slivers causes a lot of time and money. It is true that attempts have been made to accelerate the drying process in such a way that the wet ones are used

ίο Subjecting card slivers to ejection. This shows, however, that as a result of the pressing of the material to be ejected against the centrifugal basket wall becomes matted. The same evil arises when the final drying of the wet card slivers is effected by being through the same alternately sucks dry air through and presses. Here is the final drying of the wet card sliver parts that are in close contact with one another Matting cannot be avoided either.

The present invention is now a dry process, which the previously should not have the disadvantage mentioned, d. H. a quick drying without any To enable matting.

The new method consists briefly in that through the perforated in cycloidic turns Hollow spindles laid around and in the pressed state the dyeing, bleaching, etc. process subjected card slivers only for the purpose of drying dry air alternately is sucked through and pressed, for the purpose of final drying, however, while which a matting of the work item is easiest to fear, the work item pushed as a roll onto bars, on the latter broken into slices by pulling them apart and is exposed to the air causing the final drying. After this the drying is finished, the panes are pushed together again and under Preservation of the original cycloidic storage of the individual turns in the Spinning cans returned for further spinning. Since during the final drying the individual parts of the card slivers touch each other only a little, this is supposed to result in matting cannot enter.

For a clearer identification of the subject matter of the invention may the new drying process in connection with the dyeing, bleaching, etc. process on the basis of the devices in question as follows will:

ι is a spinning can, which, as already noted, is known by suitable means Movement receives to the cycloidic, illustrated in the plan according to FIG. 3 insertion to enable the card sliver. In the spinning can 1 is the one with perforations 7 and hollow spindle 2 provided with a mandrel 50 attached. The latter owns below the cone 3 with which it rests on the spinning can bottom 5 and one above the cone 3 6. After the card sliver has been inserted into the

The spinning can is inserted, the hollow spindles with the work piece from the individual Spinning cans pulled out. It is recommended to remove the hollow spindle after removing the To provide the mandrel with a handle (Fig. 2), in order to lift the spindle with the work material comfortably out of the spinning cans. Then a head plate 8 is pushed over each hollow spindle 2 and pressed together (pre-compression) of the inserted card sliver approximated accordingly to the foot disk 6, whereupon the position of the head plate is determined by suitable means,

z. B. is secured by a wedge 9 (Fig. 2).

Now the hollow spindles with the pre-pressed material are put into the known dyeing devices used, which allow, under control of the respective compression of the work quality the dye liquor in the direction from the outside to the inside or vice versa through the work material to suck. As soon as the dyeing liquor still present in the work is finished sucked or pressed off from the same and, if necessary, by pressing through With cold or hot air a pre-drying of the fuse has been achieved, the spindles are used pulled out of the dye tub, by removing the disc 8, the pressure is released and in the hollow spindles a cylindrical smooth rod 22 (FIG. 4), the length of which is considerably larger than that of the spindles. The work item is pushed up onto this rod after the Rod pulled apart in a horizontal position and cut into disks 23. Then one lets the warm air from a drying room or a continuously operating drying machine have an effect on the drawn-out panes or layers of the work item, creating a very rapid drying of the same is made possible. When the drying is complete, the slices are from this stick to a shorter stick transferred and pushed together on the same, creating the original disk storage is reached again. This last-mentioned rod is then used with the work in the spinning can., Whereupon the other Spinning the tape continues.

Claims (1)

Patent claim: Process for drying card, draw frame, combing machine tapes, cotton cords and similar band-shaped fiber material, which is placed in spinning cans around perforated spindles in cycloidic or similar Twists around, pressed together and then subjected to the dyeing, bleaching, etc. process in a vat Has been, characterized in that the work after dyeing, bleaching and the like. And optionally after the passage of dry air through the work material sitting on the spindles pushed onto bars as a roll cut it into slices by pulling it apart, then exposed it to the dry air pushed together again and while maintaining the original cycloidic storage of the individual turns in the Spinning cans is returned for further spinning. 1 sheet of drawings.
