Definitions

  • the present invention relates to modifications and improvements in the thread treating nozzle described and claimed in our European Patent Application No. 85ll2265.5, which is to be published on l8 June l986 under the Publication No. l84625, and in the corresponding U.S. Patent Application S.N. 06/67759l filed December 3, l984, in the name of Werner Nabulon.
  • These Patent Applications will be referred to herein­after as the "prior applications”.
  • Great Britain is specified in the "designation of states" in the prior European Application.
  • the prior applications describe and claim an arrange­ment which, for convenience, will be referred to brief strictlyly as an "elastic-sided" thread treating nozzle.
  • the nozzle comprises a plurality of parts, which define a thread treating passage between them, and which are movable relative to each other to enable opening of the nozzle for thread insertion, and subsequent closing of the nozzle with the thread in the passage.
  • at least one part is made elastic under closing forces applied in use, so as to ensure that sealing contact is made between the parts around the passage. It now appears, however, that this concept is broadly disclosed in British Patent Specification No. l3l0227 (corresponding with German published Application No. 2049740), in particular in claim 2 thereof.
  • the basic nozzle structure to which the present in­vention is to be applied is disclosed in the prior applications referred to above.
  • This structure com strictlyprises first and second parts which define between them a thread passage through the nozzle, the parts being movable relative to each other in order to open the nozzle to enable insertion of thread into the passage and to close the nozzle around the thread.
  • the structure further comprises infeed means for feeding a treatment fluid to the passage to flow therethrough and draw the thread along the passage.
  • the first part of the nozzle has first and second seal­ing surfaces disposed on respective opposite sides of the passage, and corresponding first and second sealing surfaces are provided on the second part.
  • Closure force applying means is provided to apply closure forces urging the first and second sealing surfaces on the first part into engagement with the first and second sealing surfaces respectively on the second part. At least one of the parts is flexible under the action of the applied closure forces.
  • the closure force applying means engages the flexible part on a face opposite to and substantially aligned with said passage.
  • the arrangement also enables face to face sealing con­tact to be made on both sides of the passage in seal­ing zones immediately adjacent the passage.
  • the parts can be formed to provide a predetermined passage cross-section, which will be maintained even under the application of closure force in use.
  • the passage cross-section is not, of course, necessarily uniform along the length thereof; it may vary in a predetermined fashion along that length, but should not change in an uncontrolled fashion in re­sponse to application of operating forces.
  • Closure force may be applied to the one part by con­tact of the closure force applying means with a zone of the part which is localized relative to said first and second sealing surfaces on the parts, i.e., the area of the zone may be much less than that of the surfaces.
  • the closure force applying means preferably con­tacts the one part at positions on respective differ­ent sides of the passage, so that closing pressure is effectively generated on both sides of the passage.
  • the nozzle assembly 200 shown in Fig. l comprises a thread treating nozzle made up of a relatively rigid block 2l0 and a relatively elastic plate 2l2.
  • block 2l0 has a groove 2l4 extending from end to end thereof and forming a thread passage through the nozzle.
  • the thread passage is provided solely by this groove 2l4 in block 2l0.
  • a corresponding groove 2l6 can be provided in plate 2l2, so that at least part of the thread passage is made up by the combination of grooves 2l4, 2l6.
  • An embodiment of this type is illustrated in Fig. 2, in which the thread passage made up by grooves 2l4 and 2l6 is indicated at 2l8.
  • Block 2l0 is provided with infeed means generally indi­cated at 220, by means of which a treatment fluid is fed into the thread passage at a position between the ends thereof.
  • infeed means generally indi­cated at 220, by means of which a treatment fluid is fed into the thread passage at a position between the ends thereof.
  • a suitable arrangement for this purpose is shown in the prior applications, and also in our European Patent No. l23829. Accordingly, those details will not be repeated here.
  • the treatment fluid flows from its entry point into the thread passage downwards as viewed in Fig. l, thereby drawing a thread in the passage in the same direction as indicated by the arrows at the top and the bottom of the nozzle shown in this figure.
  • the upstream portion of the thread passage i.e. the portion there­of upstream from the entry point of the treatment fluid, is in any event provided simply by a groove in block 2l0 without any corresponding groove in plate 2l2.
  • the nozzle illustrated in Fig. l does not in­clude an integral texturizing chamber.
  • the illustrated nozzle is designed primarily to exert a forwarding effect on the thread.
  • the fluid may be arranged to heat the thread, or at least to maintain a thread temperature previously achieved by preheating.
  • the box 222 in Fig. l represents a receiving device for re­ceiving the thread forwarded by the nozzle.
  • device 222 can be designed to texturize the thread, but in a manner radi­cally different from that illustrated in the prior applications.
  • the nozzle shown in Fig. l could equally be used in conjunction with a texturiz­ing chamber as shown in those prior applications. How­ever, receiving device 222 could also take other forms.
  • the nozzle is of the openable and closable type to facilitate in­sertion of thread into the thread passage, such as passage 2l8 in Fig. 2.
  • block 2l0 is mounted in a housing portion 224 which is fixed to a suitable carrier generally in­dicated at 226.
  • Carrier 226 and housing 224 have suitable openings aligned with infeed means 220 in Fig. l to enable suitable supply of the treatment fluid.
  • Plate 2l2 is mounted in a second housing portion 228 which is acted upon by a piston and cylinder unit 230.
  • housing por­tion 228 is forced to the right as viewed in Figs. l and 2 so as to engage housing portion 224 at a contact surface 232.
  • the nozzle is closed simultaneously, but the closure forces are not applied directly from the piston and cylinder unit 230; instead, they are applied by resilient means indicated at 234 in Fig. 2.
  • This resilient means may comprise packets of cup springs (Belleville washers) as indicated at 234 A in Fig. l, or spiral compression springs as indicated at 234B in Fig. l.
  • a method of mounting the plate 2l2 on housing portion 228 without interfering with the closing action applied by the resilient means 234 is indicated dia­grammatically in Fig. 4.
  • a packet of Belleville washers 234A encircles a mounting pin 236 which is fixedly secured at one end, for example by screws, to plate 2l2.
  • Pin 236 extends into a bore 238 in a sleeve 237 fixed (for example by screws) to housing portion 228, and is movable in that bore within limits defined by confining means now to be described.
  • sleeve 237 has an in­wardly projecting flange 240 engageable with a flange 24l on pin 236 to limit movement of plate 2l2 to the right (as illustrated in Fig. 4) relative to the hous­ing portion.
  • Plate 2l2 can, however, be forced to the left (as viewed in Fig. 4) relative to housing portion 228 against the bias applied by springs 234A until plate 2l2 sits on sleeve 237.
  • plate 2l2 and block 2l0 ideally make sealing contact at all points on a sealing plane which intersects the passage 2l8 and which may be considered to be defined by a first pair of sealing surfaces 242 lying above passage 2l8 as viewed in Fig. 2, and a second pair of sealing surfaces 244 lying below the passage in that figure.
  • Each pair of surfaces comprises one surface on block 2l0 and one surface on plate 2l2.
  • Plate 2l2 is designed to present a planar surface to block 2l0, giving a thread passage accurately designed by the groove 2l4A in block 2l0.
  • a zone of contact between plate 2l2 and the closure force applying means (resilient means 234) is indi­cated by the diagrammatically illustrated element 246 of the closure force applying means.
  • This element can, for example, be one of the Belleville washers 234A, a part of the compression spring 234B, or (as in the pre­ferred embodiment according to Fig. 4) a pressure plate interposed between the resilient means 234 and plate 2l2.
  • the region of contact defined by element 246 is aligned with groove 2l4A (as previously disclosed in the prior application) thereby ensuring sealing contact of the surface pairs 242, 244 in the regions immediately adjoining groove 2l4A.
  • Fig. 5 B indicates an alternative arrangement based upon principles shown in German published Patent Specification (Auslegeschrift) No. 2049740. In this arrangement, closing force is not applied in alignment with groove 2l4A, but adjacent a non-illustrated hinge joining plate 2l2 and block 2l0 at one longitudinal edge thereof, assumed to be to the left of Fig. 5 B.
  • a further closure force is applied to correct the defect in Fig. 5 B by urging the edge region of plate 2l2 remote from the hinge into contact with block 2l0, then the result illustrated in Fig. 5 C may be ob­tained.
  • sealing contact is made by the surface pairs 242, 244, but this sealing contact occurs in regions spaced from the groove 2l4A. Due to high operating pressure in the thread passage, the elastic plate 2l2 bows slightly as indicated at 250 in the region of groove 2l4A, and the effective cross-­section of the thread passage is no longer determined solely by the form of the triangular-section groove.
  • Flexibility of plate 2l2 is determined by the material of the plate, and its form and dimensions. The flexi­bility of the plate must also be considered in relation to the applied closure forces.
  • the arrangement illustrated in Fig. 5 D In this case, contact is made between the sealing surface pairs 242, 244 in the required regions adjacent groove 2l4A.
  • the latter may be deformed into the groove 2l4A as indi­cated in exaggerated fashion by the ridge 252 in Fig. 5 D.
  • a highly deformable (rubber-like) material in the plate 2l2 With a highly deformable (rubber-like) material in the plate 2l2, the effect illustrated in Fig.
  • a metal is preferred for the heat conductivity reasons already discussed in the prior applications.
  • the better heat conducting metals are often not resistant to substances present in the treatment fluid (for example, to spin finish applied to synthetic filament threads before they enter the texturizing stage of the production process). Chemical interactions may destroy the nozzle surface in the thread passage and/or have an undesirable effect on the threads pro­cessed. This is especially true at higher processing temperatures. Nozzle temperatures in the range l50 °C to 400 °C are used in texturizing synthetic filament threads, but temperatures in the range l60 °C to 280 °C are most common.
  • the metal can be provided with a protective coating, but this will wear away and expose the underlying me­tal sooner or later. Accordingly, the preferred solu­tion is to form the passage itself in parts made of a hard metal, which is inherently chemically resistant, and to enclose these parts in a housing having rela­tively good heat conducting properties.
  • Stainless steel rust-resistant steel
  • other tough, chemical and erosion-resistant metals can be used provided plates thereof can be manufactured in the required dimensions (with an adequate degree of flexibility).
  • the simple rectangular form (with or without a groove to define the thread passage) is preferred as illustrated in Fig. 2.
  • This form of plate is relatively simple to manufacture.
  • the sealing surfaces 242, 244 could be curved in transverse cross-section when the nozzle is closed.
  • a stainless steel plate in the form shown in Fig. 2 may have a thickness in the range 2 to 8 mm, and a width in the range l2 to 25 mm.
  • the lower limit of the plate thickness is given by the conveniently available means for manufacturing such a plate in the required form, while the upper limit of the thickness range is given by the loss in flexibility arising with increasing thickness.
  • the preferred thick­ness range is 3 to 6 mm.
  • the thickness of a corresponding stainless steel block 2l0 may lie in the range 8 to l5 mm. This thickness is relatively unimportant as far as flexibility/rigidity of the structure is concerned because the block is in any event extensively supported by the corresponding heat conductive housing portion 224.
  • the thickness of the steel block is preferably kept low for reasons of conductivity, however.
  • the length of the plate 2l2 is clearly dependent upon the details of the nozzle design; there will be a radi­cal difference, for example, between a plate for use in a nozzle comprising an integrated texturizing chamber (as illustrated in the prior application) and a plate for use in a nozzle providing primarily a forwarding action urging a thread into a separately formed textu­rizing section, as generally indicated in Fig. l and as will be subsequently described with reference to Fig. 6.
  • the length of the plate is of less significance as regards flexibility than the width thereof. If the plate is sufficiently flexible in the transverse direction (across its width) it will almost certainly prove to have sufficient flexibility in the longitudinal direction (along its length). As shown in Fig.
  • a number of closure force applying devices can be spaced along the length of the nozzle to ensure that strip-like sealing con­tact zones are created to either side of the passage 2l8 along the full length thereof.
  • the devices may be longitudinally spaced by a distance (center to center) of between l5 and 30 mm along the length of the thread passage.
  • the overall length of a nozzle as shown in Fig. l (corresponding to the overall length of plate 2l2) may lie in the range 60 to l50 mm. Shorter nozzles generally are associated with higher operating tempe­ratures.
  • Each closure device (resilient means 234, in the form of a spiral compression spring or packet of Belleville washers) may be adapted to apply a force in the range 400 to 800 N.
  • the total closure force applied to plate 2l2 by all of the closure devices aligned with the thread passage 2l8 may lie in the range l'000 to 3'500 Newton, and there will commonly be four to six such devices in a nozzle of the form shown in Fig. l.
  • the piston and cylinder unit 230 is preferably adapted to apply a greater force to the housing portion 228, for example a force exceeding the total closure force applied to plate 2l2 by approximately 50%.
  • the plate 2l2 must be flexible to enable sealing contact to be made as described above, the material of the plate must be able to resist localised deformation in the region of the thread passage. This has been explained by reference to Fig. 5 C and Fig. 5 D for the case in which the plate is designed to bridge a preformed groove in the other nozzle part. It applies equally, of course, where the passage is made up by grooves in both parts.
  • the passage cross-section may lie in the range 2.5 to l0 square millimeters at the junction region where the thread and treatment fluid are first brought together, and it may increase to a value in the range 6 to 20 square millimeters at the downstream end of a nozzle as shown in Fig. l.
  • the high pressures at the junction region are likely to lead to the greatest deformation problems.
  • the elastic plate and the corre­sponding block
  • plate 2l2A and block 2l0A define two thread passages 2l8A and 2l8B.
  • a sepa­rate set of closure force applying devices is provided for each thread passage, one set being indicated at 234X and the other set at 234Y
  • the width of plate 2l2A is approximately double the width of plate 2l2; thus, a stainless steel plate 2l2A pre­ferably has a width in the range 24 to 30 mm.
  • the thickness of plate 2l2A still lies in the range 2 to 8 mm, however.
  • Piston and cylinder unit 230A must be adapted to apply to housing portion 228A a force ex­ceeding the total force applied to plate 2l2A by both sets of closure devices 234X, 234Y acting together.
  • the lines of action (vectors) of the force applying means acting on the plate 2l2 preferably extend substantially at right angles to the sealing surfaces 242, 244.
  • the play provided in the mounting shown in Fig. 4 enables this effect to be maintained even when plate 2l2 flexes to accomodate slight misalignments in the nozzle structure - there is a corresponding tilt in the pin 236 relative to sleeve 237 in the flexed re­gion of the plate.
  • the sealing surfaces themselves are preferably finished by grinding operation during manufacture. There is no need for fine finishing operations such as lapping, polishing or superfinishing.
  • Fig. 6 indicates in a highly diagrammatic manner the use of a nozzle in the form shown in Fig. l in a thread texturizing system which differs from that shown in the prior application.
  • the nozzle structure is again generally indicated at 200.
  • Housing portion 228 and the elastic plate 2l2 provided therein are generally as shown in Fig. l, but housing portion 224 is formed at one end to match the surface of a rotating drum 260 which receives the thread from the forwarding nozzle 200.
  • Drum 260 rotates in an anti-clockwise direction as viewed in Fig. 6.
  • the thread 262 has traveled with drum 260 through approximately half a revolution thereof, it is transfered to a cooling means which is not shown in Fig. 6.
  • a casing portion 264 encircles drum 260 between the outlet from nozzle 200 and the location of transfer to the cooling means. Drum 260 and casing portion 264 are heated and form the actual tex­turizing chamber receiving thread from the forwarding nozzle 200.
  • This form of texturizing system is of a known type, being described for example in U.S. Patent Specifications No. 40246ll, 4074405 and 40l9228. Accordingly, details of such arrangements will not be provided in this specification.
  • treatment or "treating” is intended to cover any application of a pressurised fluid to a thread, whatever the purpose of the application. Thus, even the creation of a simple drawing or forwarding effect is considered in this context as a “treatment”. In most cases, however, there will be ancillary purpose such as heating or cooling the thread.
  • both nozzle parts could be made flexible, but this may adversely affect the thermal conducting characteristics of the nozzle taken as a whole, bear­ing in mind the desirability of making the passage defining parts from a corrosion and erosion resistant metal. Good thermal conducting contact of at least one nozzle part with a body of relatively good thermal conductivity is advantageous.
