Definitions

  • the invention relates to a device of the type corresponding to the preamble of claim 1.
  • Such a device is generally known in the form of the foulard.
  • the material web is guided from above into an upwardly open trough with the treatment liquid, deflected upwards via a deflection roller arranged near the bottom of the trough and, after exiting from the treatment liquid in the trough, squeezed out by the pair of squeeze rollers arranged above, the Squeezed liquid runs back into the trough via a guide surface.
  • the volume of the trough is quite considerable for design reasons. Although it is also known to accommodate displacers in the trough, there is still a considerable volume of liquid which must be kept or disposed of when the treatment is ended or when the treatment liquid is changed. Careful cleaning is made difficult by the presence of the displacer.
  • the general goal in textile technology is to reduce the amount of treatment liquids in the apparatus more and more.
  • the invention is also based on the object of further developing a generic treatment device in the sense of reducing the liquor content.
  • the flat trough of the foulard can absorb the amount of liquid through its trough shape without sealing problems, but it requires an interior space which can accommodate the incoming and outgoing sections of the web and the deflection roller.
  • this trough is replaced by the upright, flat channel, which the web of goods passes through only once from bottom to top and which is delimited at the lower end by the sealing arrangement, i.e. is liquid-sealed.
  • the seal with respect to the running web replaces the closed trough, which, however, requires a double passage of the web sections.
  • the channel should be "flat". What is meant by this is that the clear distance between the flat flat sides of the channel opposite one another in parallel is just so large that a web of material can be passed loosely in a wide position. Whether the material web approaches the flat side more or less on its way through the channel does not matter for the impregnation effect.
  • the specific distance dimension to be selected in the individual case depends on the goods. A flat material such as a cotton fabric requires only a smaller distance than a fluffy or a pole material.
  • the arrangement of the flat sides of the flat channel with the smallest possible distance to the web has the effect on the one hand that the volume of treatment liquid in the channel can be kept low and in the case of a width of 1800 mm is only about 11 liters. Such a small amount is "used up" by the passing web in a short time, so that no problems with a possible fleet depletion occur.
  • the flatness of the channel also has an effect on the physical effectiveness of the impregnation. Due to the proximity of the flat sides of the channel to the web passing through, a flow-like interaction occurs, insofar as strongly turbulent flow layers arise on both sides of the web, the pressure pulsations of which promote the venting of the web and the accompanying penetration of the treatment liquid into the web . The impregnation efficiency with a comparable impregnation section increases significantly compared to the conditions in the paddling pool.
  • the sealing arrangement at the lower end of the channel can be carried out in the manner set out in claim 2.
  • An application device with a flat, upright channel, which can be filled with treatment liquid, with a sealing arrangement of the type described is known per se from DE-OS 14 60 265.
  • the web is passed through the flat channel from top to bottom and the squeeze rollers are arranged below the channel.
  • sealing arrangement can be designed in the manner set out in claims 3 and 4, but which is known per se, e.g. from DE-OS 14 60 268 and DE-OS 14 60 265.
  • Canal materials are suitable plastics or corrosion-resistant steel.
  • the clearance between the flat sides of the channel according to claim 7 is approximately 6 to 15 mm.
  • a size of approximately 10 mm is generally considered.
  • the loading of the flat channel can be carried out in a manner known per se according to claims 8 and 9, the application of the treatment liquid to be supplied to the drainage surfaces taken from DE 37 33 996 C 2 per se.
  • the hose section according to claim 11 which forms a problem-free and inexpensive seal between the end of the dimensionally stable channel and the inflatable hoses, which in particular seals easily and without on the sides of the web to be bound to a certain web width.
  • a similar hose section can also be seen in DE 14 60 265 A1, but it is arranged there in the interior of the flat channel and its upper edge is fastened. Because of the greater height of the immersion or watering section in the invention, this means the necessity of arranging a rather long hose section with corresponding costs, the material having no function outside the actual sealing zone. In the case of the invention, however, the hose section only needs to bridge the zone between the lower end of the flat channel and the sealing arrangement arranged below it.
  • the feature of attaching the hose section on the outside of the flat channel is particularly important if a slide film is also to be provided, which is intended to facilitate the sliding of the product web through the inflatable hoses facing one another.
  • a slide film is also to be provided, which is intended to facilitate the sliding of the product web through the inflatable hoses facing one another.
  • the application of such a sliding film would only reasonably be possible at the upper edge of the channel.
  • the slide films would then have to cover the entire height of the extend flat channel or be attached to the hose section at half height. Both solutions are structurally not cheap.
  • the slide films can have an optimal brevity without there being problems with their fixing against the train of the material web.
  • the tube section and the fastening of the slide film are features which can also be used independently of the question of whether squeeze rollers are arranged above the upper end of the flat channel. These features therefore have a meaning even without the dependence on claim 1.
  • a practical design is the subject of claim 13. It allows the production of test specimens of smaller width under conditions similar to production without great expenditure of treatment liquid.
  • a region of the channel corresponding to the width of the rectangular pouch is filled in so that treatment liquid cannot penetrate into this region. Only the remaining width of the channel remains on one side, for example, through which a narrow strip of textile material can be passed and in which only a very small amount of treatment liquid is present.
  • the pattern strip is treated in the same way as would be the case later with a wider web. In this way, samples closer to production can be produced than on a laboratory machine separate from the system.
  • the bag is inserted into the channel from above, the strip according to claim 14 forming the support on the upper end of the channel and holding the bag in the correct position.
  • connection for inflating the bag on the bar is also expediently provided (claim 15).
  • a practical embodiment is the weight bar according to claim 16, which is at the lower end of the bag is provided and ensures that the bag, which consists of flexible plastic film, can easily be hung into the flat channel under the weight of the weight bar.
  • Fig. 1 shows a vertical section perpendicular to the web through a watering device
  • FIG. 2 shows the area of the sealing arrangement from the lower part of FIG. 1 on an enlarged scale
  • Fig. 3 shows a horizontal partial section along the line III-III in Fig. 2;
  • FIG. 4 shows a view corresponding to FIG. 1 of a modified embodiment
  • FIG. 5 shows a view according to FIG. 4 from the right.
  • the impregnation device designated 100 as a whole in FIG. 1 serves to impregnate, for example, a textile web 1 with a treatment liquid in a predeterminable moisture content.
  • the impregnation device 100 comprises an upright flat channel 10 which can be filled with the treatment liquid and through which the material web 1 passes from bottom to top.
  • the flat channel is closed at the bottom by a sealing arrangement 20, which bears against the web 1 from both sides and prevents the treatment liquid from running out of the flat channel 10 downwards.
  • a squeezing mechanism 30 is arranged with two squeezing rollers 32, 33 working against each other, which squeeze the web 1 soaked in the flat channel 10 to a predeterminable moisture content, so that a certain amount of treatment liquid on the web 1 remains in an even distribution.
  • the web 1 runs from above via one below
  • the spreader roller 2 arranged in the impregnation device 100 is deflected there by approximately 90 ° and reaches a deflection roller 3 approximately horizontally. From the right side in FIG. 1, the web runs vertically upwards and above the flat channel 10 via a further spreader roller 4. to then run into the nip 31 of the nip rollers 32 and 33.
  • the flat channel 10 consists of two opposing rectangular sheets that are parallel to one another at a small distance and form the flat sides 5, 5 of the channel 10. The longer sides of the rectangular sheets are located in the width direction of the web. Between the upright, shorter sides, a spacing profile 6 with a rectangular cross section is arranged on the edge, with side profiles 7, 7 on the outside. The whole is connected by a series of screws 8 and sealed in a suitable manner, so that there is a channel which is closed in a horizontal section.
  • the flat channel 10 opens out at the top and bottom.
  • a support structure is provided, of which only two I-beams 11, 12 opposite one another are shown at the same height.
  • the carriers 11, 12 each have a transverse web 11 ', 12' at a distance from one another. In the spacing space on the transverse webs 11 ', 12' holding pieces 13, 14, 15 are mounted, which hold the lower end of the flat channel 10 and the seal arrangement 20. If necessary, the flat channel 10 can be supported at another point in a manner that is not reproduced.
  • the plates or sheets forming the flat sides 5, 5 of the flat channel 10 are angled outwards and form inwardly inclined drainage surfaces 16, via which the treatment liquid in a film or a layer obliquely downwards into the upper end of the flat Channel 10 runs in.
  • Outside the drain surfaces 16 are horizontal feed pipes 17 for treatment liquid which extend parallel to the flat sides 5, 5 provided, which are supplied with it in a suitable manner and are connected to a large number of arc tubes which follow one another in the width direction and which are bent in the manner of a walking stick and extend over the upper edge of the drainage surfaces 16.
  • the treatment liquid which is brought to the drainage surfaces 16 at a large number of points which are fairly close to one another through the curved tubes 18 flows down over the drainage surfaces 16 and is thereby leveled out, so that the flat channel 10 has no significant level differences in the width direction of the web 1 can be kept filled.
  • the squeeze rollers 32, 33 are provided above the discharge surfaces 16 and arc tubes 18 in the area of the plan of the flat channel 10 with its support arrangement.
  • the treatment liquid squeezed in the roll gap 31 flows downward or drips off along the web 1.
  • guide surfaces 34, 35 are provided on both sides of the web 1, which collect the treatment liquid accumulating below and laterally from the pinch rollers 32, 33 and guide them to the discharge surfaces 16, where they again enter the flat channel 10 is returned.
  • the area of the sealing arrangement 20 from FIG. 1 is shown enlarged in FIG. 2.
  • the sealing arrangement 20 comprises two inflatable tubes 25 which are opposite one another at the same height on both sides of the web 1 and which have continuous T-shaped ribs 26 on the rear in the longitudinal direction, which in corresponding undercut recesses 27 of the holding pieces 13 and 14 respectively intervention.
  • the tubes 25 In the fully inflated state, the tubes 25 bear against one another under pressure. In the depressurized or evacuated state, they are flat, as is indicated by dashed lines at 25 '.
  • the arrangement of the hoses 25, 25 is such that they hold the web 1 in the middle of the flat channel 10 in the inflated state.
  • the seal assembly 20 is just below the Lower end 10 'of the flat channel 10 is arranged.
  • the flat channel 10 is surrounded on its outside by a short tube section 40 made of a plastic film, which tightly surrounds the flat channel 10.
  • the tube section 40 is therefore dimensioned in its horizontal cross section such that it fits exactly around the flat channel 10 and, if necessary, can be sealed with the aid of sealants.
  • the hose section is clamped between the outside of the flat sides 5 and holding brackets 29 which are supported on the holding pieces 15 or 13 and 14.
  • the hose section 40 hangs down over the lower end 10 'of the flat channel 10 and extends between the hoses 25, 25 in order to extend a little further beyond it to its lower edge 40'.
  • a slide film 50 is also clamped with its upper edge on each side of the web 1, specifically on the inside of the hose section 40.
  • the slide films 50 extend within the hose section
  • the slide films 50, 50 lie directly against the web 1 and consist of a durable, low-friction material, e.g. Polytetrafloräthylen or corrosion-resistant steel. They hold by their attachment
  • the hose section 40 thus has a purely sealing function without demands on mechanical strength or particularly good sliding properties.
  • the hose section seals the space between see the lower end 10 'of the flat channel 10 and the seal assembly 20 solved in a simple manner.
  • FIG 3 shows a horizontal section at the height of the hoses 25, 25 in the edge region of the web 1.
  • the thickness ratios are exaggerated. Due to the elasticity of the hoses 25, 25, the sliding foils 50, 50 and the edges of the hose section 40 outside the edge 1 'of the web are compressed and sealed by the internal pressure of the hoses 25, 25 so that there is an exact adjustment of the paste ⁇ te of the web to the width of the slide films 50.50 and the hose section 40 does not arrive.
  • Fig. 1 the flat channel 10 is interrupted at the level of point 19. This is to indicate that the height of the channel 10 and thus the impregnation section can be different if necessary. In practice, a height of about 400 - 500 mm can be considered.
