Definitions

  • the invention relates to a device of the type corresponding to the preamble of claim 1.
  • Such a device is known from DE-A 33 15 770.
  • the gap is delimited on one side by a bulging application bar, which forms the counter surface, in which a slot extending across the web is arranged, from which the treatment agent can be expressed.
  • the slot is an elongate cushion extending across the width of the web, which is supported on the side facing away from the gap against a fixed abutment in the form of a carrier extending across the width of the web.
  • the cushion is covered by a slide film, which is fixed on the edge opposite to the direction of advance.
  • the material web is pulled through the gap between the counter surface and the slide film, the treatment agent emerging from the slot in the material web being pressed into the material web becomes. Since the pillow extends over the entire width of the web and the pressure in the pillow propagates evenly, there is also a uniform pressure across the width of the web.
  • FR-A 13 81 081 Another generic embodiment is known from FR-A 13 81 081.
  • a vertical narrow treatment trough is formed, which is filled to a certain height with treatment agent and through which the material web is guided from top to bottom.
  • the walls of the treatment trough parallel to the web lie on both sides of the web and are opposed to one another by the outside against the lower wall parts; which form the gap, pressurized pressure hoses pressed against each other.
  • the counter surface is also resilient and the treatment agent is not supplied in the counter surface, but rather in the fill level in the trough through which the material web passes.
  • the web of material is drawn between the counter surface and the slide film, in the second embodiment between the walls of the trough pressed against one another. So you must have a certain tensile strength.
  • the requirements in this regard are lower in the device according to US Pat. No. 4,455,845, in which the material web is passed through a gap between a rotating drum and a belt partially wrapping around it, onto which a foamed treatment agent is patterned at a predominant point in a pattern transverse to the web neighboring streets has been applied.
  • the contact pressure between the belt and the drum in the gap is here again, due to the design, uniform over the width of the web.
  • the function of all these generic devices includes a certain pressing or massaging of the treatment agent into the web.
  • the web of goods must therefore have a certain absorption capacity for the treatment agent.
  • material webs such as fabric and in particular a fabric having a pile are considered as webs.
  • material webs such as fabric and in particular a fabric having a pile are considered as webs.
  • even thicker nonwovens with sufficient tensile strength can be processed by the method. Otherwise there are no restrictions with regard to the webs.
  • the treatment agent application is very sensitive to the pressure acting on the web as it passes through the gap. If the pressure increases at one point, the material web receives significantly less treatment agent there. This is understandably particularly noticeable in the case of polar articles and is also plausible insofar as the volume of the pole is reduced by the compression and thus the volume of the liquid is removed and at the same time the remaining volume of the pole becomes less absorbent for the liquid because the material is compressed more and for this reason is no longer so absorbent.
  • the two effects therefore overlap, and even relatively slight differences in pressure result in clearly discernible differences in the depth of color, for example when dyeing with liquid treatment agent. This can lead to problems with uniformity, especially at the edge of the web, where the uniformity of the print can sometimes not be completely guaranteed, and where the structure and edge position of the web also absorbs the dyeing liquid differently from the center, even with uniform pressure the coloring.
  • the invention is therefore based on the object of specifying a simple sampling device with uniform treatment loss over the area.
  • the detected sensitivity of the method to different pressures is therefore used positively for sampling purposes.
  • the resilient pressure that is exerted on the web by the gap is therefore no longer, as in the generic prior art, inevitably uniform over the entire width of the web, but can deliberately be made uneven.
  • the different pressure controls can be used to achieve a different pattern across the surface of the web, for example a shaded or veiled color, as may be desirable with some fashionable fabrics or with floor coverings.
  • the pattern-specific non-uniform specific pressure can vary both spatially, ie in the transverse direction of the web, and in time when it passes through the gap, so that different depths of color prevail in different areas along the web at one and the same point in the width direction.
  • This patterning is modified by the elastically flexible transmission elements.
  • These have inherent stability, as is the case with thick-walled hoses, cylindrical or rod-shaped elastomeric profiles or the like. If such elements are pressed together in one place, any point sufficiently distant to the web remains unaffected or almost unaffected.
  • a "cushion" has sagging walls and fulfills its function in the presence of internal pressure. Without the internal pressure, however, it would collapse.
  • the last-mentioned transmission elements do not collapse even without internal pressure because of their dimensional stability. However, it is also possible to use elements that combine both properties, for example a relatively stable hose with internal pressure.
  • a “pillow” in the sense of the invention is understood to mean a hollow body with flexible walls, which is filled with a fluid medium under a certain pressure receives a uniform internal pressure over its entire extent and also passes this internal pressure to the web essentially evenly when it comes into contact with the web.
  • a pillow is available in DE-C 33 l5 770.
  • the continuous pillow there is divided into several sections or individual pillows adjoining each other across the width of the web, which can be filled or inflated with the fluid medium independently of one another, so that in the area of a single section essentially uniform pressure, but different pressures can be exerted in adjacent sections.
  • the bar or plate should serve to increase the inherent rigidity of the transmission element, so that no significant changes in pressure can occur across a short distance across the web. Over longer distances, however, the bar or plate should still be deformable, so that he or she can compress the transmission element in different areas transversely to the web and thereby produce different pressure effects in the web.
  • the embodiment can be made in accordance with claim 3.
  • Fig. 1 shows a cross section in a longitudinal plane perpendicular to the web of a carpet dyeing device according to the invention
  • Fig. 2 shows a sectional view along the line II-II in Fig. 1;
  • Fig. 3 shows a cross section corresponding to Figure 1 of an opposite embodiment along the line III-III in Fig. 4.
  • Fig. 4 shows a sectional view along the line IV-IV in Fig. 3;
  • FIG. 5 shows a sectional view according to FIG. 1 of a third embodiment along the line V-V in FIG. 6;
  • FIG. 6 shows a sectional view along the line VI-VI in FIG. 5.
  • the fabric web 1 is a carpet web, which is guided with the pole 1 'upwards over parallel guide rollers which are not shown, are parallel and are arranged at approximately the same height.
  • the web 1 lies against the counter surface 5 in a certain area. Approximately in the middle of the area, an inner chamber-forming slot 28 is provided in the application bar 24, which extends approximately perpendicular to the counter surface 5, opens out into the latter and passes over the length of the order bar 24 or the width of the web 1.
  • the feed channels 9 are evenly supplied with liquid treatment agent, for example coloring liquid, from a distributor (not shown).
  • the treatment agent is fed via the feed channels 9 to the slot 28 at locations distributed over its length.
  • the feed takes place at a right angle to the slot 28, so that the treatment agent, before it can exit from the slot 28 into the web 1, is deflected and thereby further equalized.
  • the exit width can be adapted to the width of the web 1 by moving the shaped pieces 26 (FIG. 2) that fill the slot 28 in its cross section and limit it to the outside.
  • a resilient pressing element is arranged above the web 1, which presses the web 1 sealingly against the edges of the gap 28. It is supported on an abutment 39 which extends across the web 1 and has the shape of a carrier which has a chamber 32 which is open at the bottom.
  • the chamber 32 is delimited in the longitudinal direction of the web 1 by legs 33, 34 which extend perpendicular to the web 1 and between which a plate 38 which is continuous over the width of the web 1 can be displaced in the direction perpendicular to the web 1.
  • the plate has a continuous T-groove 42 on the side facing the web 1, into which a T-shaped longitudinal extension 43 engages on the tubular hollow profile 44 forming a flexible transmission element 60.
  • the tubular hollow profile 44 lies on the sides of the carrier 39, as can be seen in FIG. 1 attached slide film 41 and presses the slide film 41 against the web 1 and the web 1 against the mouth edges of the slot 28. It has its own rigidity, ie a compression resistance increasing with the deformation in its transverse direction even without a filling with a fluid medium.
  • the plate 38 is in turn supported by a plurality of pressure elements 45, 46, 47, which act together as a pressing element and are designed as inflatable hollow bodies and are arranged between a web 48 connecting the legs 33, 34 and running parallel to the web 1 and the top of the plate 38 and without filling with a fluid pressure medium need not have usable dimensional rigidity.
  • the pressure elements 45, 46, 47 can be pressurized separately, as a result of which the plate 38 can bend in the manner shown in FIG. 2 if the pressure in the pressure element 45 spanning the central region of the web 1 is slightly lower than the pressures in the separate printing elements 46, 47 near the edge is selected.
  • the plate 38 is so rigid that there are no deformation stages at the borders between the pressure elements 45, 46, 47, but that the plate 38 can bend in larger areas due to different pressure in the pressure elements 45, 46, 47 in the manner indicated .
  • the bending of the plate 38 is transferred to the flexible transfer element 60, which, where it is compressed more, namely in the exemplary embodiment at the edges, transfers more pressure to the slide film 41 or the web 1 than in the middle.
  • the treatment agent was supplied through the gap 28 in the counter surface 5, which was formed by a rigid part.
  • the embodiments 90 and 110 according to FIGS. 3 to 6 there is no supply of treatment agent in the gap 25 and the counter surface is also flexible.
  • a narrow vertical trough 52 is formed by two sliding foils 61 lying opposite one another in the manner indicated, through which the material web 1 is guided vertically from top to bottom and at the two edges of the material web 1 is sealed in a suitable manner.
  • the sliding films 61 approach each other and lie in the gap 25 from both sides of the web 1.
  • the other side of the slide films 61 is supported against the mutually facing sides of beams 62 which are opposite one another on both sides of the web 1 and extend transversely to the web 1.
  • the bars 62 have mutually opposite channels 63, in which flexible transmission elements 100 are arranged, which are designed as thick-walled tubes 64.
  • the tubes 64 pass through the width of the web 1 and have a compression resistance due to the rigidity of the walls.
  • they are filled with air at an adjustable pressure, so that a pressure which is constant across the length of the tubes 64 and is caused by the air and an additional pressure which arises as a result of local compression and deformation of the tubes 64 are superimposed.
  • the bars 62 are guided by bolts 65 on the webs 68 parallel to the web 1 of abutments 69 extending across the width of the web 1 in the form of supports in such a way that they are perpendicular to the web Can move web 1 against each other.
  • the webs 68 are arranged outside the beams 62, and there are pressure elements 67 in the form of a pressure hose between the webs 68 and the beams 62, which are divided into a central section 72 and two outer sections 73 by crimp connections 71.
  • Each section 72, 73 has its own connection in the manner shown in FIG. 4 and can accordingly be provided with its own internal pressure by pumping in a fluid medium, for example compressed air, so that it represents a separate, independently actuatable pressure element.
  • the bar 62 bends slightly, as a result of which the tube 64 experiences a different compression along its length and transmits correspondingly different forces to the sliding roll 61 or the web 1.
  • the web 1 takes liquid with it as it passes through the trough 52, which is pressed into the gap 25 by the pressure of the resilient pressing element 67, which is transmitted to the web 1 via the slide films 51, and worked into it.
  • the device 110 of FIGS. 5 and 6 differs from the device 90 only in that the flexible transmission elements 120 are formed by thick-walled hoses 74 made of soft rubber which can be open at the ends. Solid cylindrical profiles made of soft rubber can also be used. These resilient transmission elements only work due to their compression resistance, but do not contain any internal pressure that is constant across the width.
