Definitions
- the invention relates to a foulard with a wrapping roller for a textile web to be treated, a trough for receiving a liquor which is transferred from the trough to the wrapping roller and from there to the web, and optionally with guide rollers for the web.
- DE-OS 2 733 804 describes such a foulard.
- An endless idler belt runs there around a roller immersed in the trough and around the wrapping roller and thereby transports the liquor from the trough to the wrapping roller, where it is transferred to the web.
- a squeeze roller on the wrapping roller.
- Another squeeze roller can also be in contact with the wrapping roller in front of this squeeze roller.
- this has the disadvantage that printed goods cannot be treated with this foulard, since the printing inks would take place in the nip from the endless idler belt to the web. After only a few turns, the printed goods would be contaminated by the dye on the idler belt.
- this previously known foulard is structurally relatively complex, in particular due to the two squeeze rollers and the endless idler belt. A fine dosage of the fleet transferred to the web cannot be satisfactorily achieved.
- the invention is therefore based on the object of proposing a foulard with which an adjustable and as small a quantity of liquor as possible can be applied in a metered manner to the web to be treated in the foulard.
- this is achieved according to the invention in that a doctor rests on the circumference of the wrapping roller, which is held against the wrapping roller over its entire length with magnetic force, and in that on the contact surface of the doctor knife resting on the wrapping roller A large number of recesses lying side by side is attached.
- the recesses act as passages for the fleet. In the areas between these passages, the doctor blade lies uniformly along the circumference of the wrapping roller over its entire length and practically no liquid can pass through there. This is due to the magnetic attraction between the doctor blade and the wrapping roller achieved, which ensures a uniform contact of the squeegee over the entire length. A depth of a few hundredths of a millimeter is generally sufficient for the cutouts. The depth and the width of the recesses are selected in accordance with the respective application, so that an optimally adapted doctor blade is available for each application.
- the magnetic force acting over the length of the doctor blade and the wrapping roller according to the invention prevents the formation of gaps which would otherwise occur solely by the doctor blade sagging. Experiments have shown that an unintended gap width of only a few hundredths of a millimeter has a disadvantageous effect, which is avoided according to the invention.
- a preferred embodiment is characterized in that the doctor blade is provided behind the trough in the direction of rotation of the wrapping roller.
- the wrapping roller is immersed in the trough and the liquor taken along is wiped off the doctor blade down to the remaining, metered remaining film.
- doctor blade transfers the liquor from the trough to the wrapping roller.
- a circular doctor blade is used which, because of the properties described, only transfers as much liquor from the trough to the wrapping roller as is required in a metered manner.
- a Magnet provided in the wrapping roller under the surface thereof in the area of the doctor, which extends over the length of the doctor.
- the magnet can be a permanent magnet or it is an electromagnet.
- An electromagnet is preferred because its magnetic force is precisely adjustable.
- the magnetic force of a permanent magnet can also be adjusted, for example by changing the distance of the relevant pole of the permanent magnet from the doctor blade.
- the magnet is adjustable in the circumferential direction of the wrapping roller.
- a flat doctor blade If a flat doctor blade is used, it should be designed with a comb-like profiled contact surface. In the case of a circular doctor blade, this should have a thread-like profile, because this is easier to manufacture than a possible profile with tangential grooves.
- At least one support roller with adjustable contact pressure preferably adjustable in the circumferential direction of the wrapping roller, is applied to the wrapping roller.
- the looping route can also be designed variably and thus easily adapted to the absorbency of the textile material. This makes it possible to further influence the amount of liquid transferred, in that after a more or less long dwell after the metering knife, on which the liquid film can even out, a variable looping distance is provided, in which the textile material has the amount of liquid applied to the desired extent, i.e. more or less complete.
- a textile fabric web 2 is fed to a wrapping roller 3 via a guide roller 1.
- the wrapping roller 3 dips into a trough 6 with a continuously adjustable fleet level.
- the excess liquor taken along is removed by a doctor 4 according to FIG. 1 or 2.
- a defined amount of liquor remains on the wrapping roller 3, which is transferred to the textile web.
- the doctor blade 4 is pressed against the wrap roller 3 by a magnet 5.
- the magnet is a permanent magnet or an electromagnet.
- the doctor blade is therefore made of an iron alloy.
- the textile fabric web is pressed against the wrapping roller 3 by support rollers 7, the support pressure of the support rollers also being generated by a magnet 8 or by a pneumatic system.
- the textile material web is removed from the wrapping roller 3 via a guide roller 9.
- doctor blade 13 is thus a circular doctor blade according to FIG. 2.
- the textile web 2 is guided over the guide roller 1 to the wrapping roller 3 and pressed over the lay-on roller 7 before it is removed by the guide roller 9.
- the doctor blade 13 and the lay-on roller 7 are pressed by magnets 5, 8.
- the doctor blade 4 is omitted here because the metering of the fleet takes over the doctor blade 13.
- FIG. 3 also shows the possibility of feeding the textile web 2 (dashed web in FIG. 3) via the guide roller 1 to the wrapping roller 3, which now rotates clockwise, the web dipping into the liquor in the trough 6 and then via a doctor blade 11 is squeezed.
- This squeegee can be a hard rubber version with a smooth surface.
- the squeegee 11 is also pressed against the wrapping roller 3 by a magnet.
- the contact pressure of the support rollers 7 can also be varied by changing the number of rollers attached. Furthermore, the lay-on rollers can be pivoted in order to achieve an earlier or later pressing of the goods onto the wrapping roller 3.
- the magnets are, for example, permanent magnets or electromagnets, in order to be able to adjust the contact pressure of the doctor blade or lay-on roller against the wrapping roller.
- a cleaning device 10 for the wrapping roller can be provided, which continuously removes the impurities from the wrapping roller behind the guide roller 9.
- the foulard described can, for. B. nachge a damper, a dryer or another successor be switched.
- the comb-like incisions of the flat doctor blade according to FIG. 1 are a few hundredths of a millimeter deep.
- the amount of liquor can be metered through the variation possibilities of the gap depth and the ratio of the width of the webs to the gap width.
- a roller with a cut thread or a wound wire can be used.
- the wire is advantageously arranged in the form of a helix.
- An appropriately engraved roller can also be used. It is also possible to slide rings onto a roller, which are suitably arranged obliquely so that a uniform application of liquid takes place.
- Figure 2 shows a schematic view of such a circular doctor blade with a cut thread.
- the flat doctor blade according to FIG. 1 can be attached in a stationary manner or can be moved back and forth for the uniform transfer of the moisture film.
- the circular doctor blade according to FIG. 2 can be carried along by the wrapping roller or driven independently.
- the circumferential speed of the circular doctor blade can correspond approximately to that of the wrapping roller or be different therefrom, that is to say run slower or faster. Reverse drive of the circular doctor blade is also possible.
