Definitions
- the method of fabricating fluid nozzles having a hollow cylindrical body with an axially positioned yarn guide therein and having a restricted yarn and fluid orifice extending through a cap secured to one end of the body includes the steps of fabricating a hollow cylindrical member with an axial yarn guide extending therethrough, fixing the dimensional relationship between the yarn guide tipand the body end by forming these surfaces at the same time with a shaped tool, securing the cap upon the body end with a restricted orifice positioned in an aperture extending through the cap with the aperture positioned to define a fixed spacing between the axes of the orifice and the yarn guide, and adjusting the position of the orifice along the axis of the hollow body to fix its axial position relative to the yarn guide tip.
- This invention relates to the method of fabricating an improved apparatus for bulking or texturing continuous filament or staple 'yarns by means of fluid treatment. More particularly, this invention relates to a method of fabricating an improved yarn texturing jet in which the dimensional relationships of the 'various components thereof may be closely controlled and in which each texturizing jet within a given series may be made with substantially identical dimensions.
- Fabrics comprised of bulked or textured yarn of almost any synthetic material including glass fibers have met with considerable commercial acceptance due to their increased insulating properties, novel texture and other improved properties.
- the basic process of bulking or texturing yarn by passing it through a confined zone of turbulent fluid, such as air, is fully described in United States Patent 2,852,906. This process has been successfully used with yarns, untwisted strands and even staple fibers. It is to be understood that the term yarns as used herein is intended to include both twisted and untwisted continuous fibers as well as staple fibers.
- a major difficulty encountered in the commercial production of such textured yarns is in controlling product uniformity between yarns textured by different texturing jets. Variations in the textured yarns produced by different jets, which adversely affect the appearance and performance of a product using such yarns, are caused by (1) variations in the relationship of the rate of feed of untextured yarn to the jet to the take-up rate from the texturing jet, (2) by variations in air pressure supplied to the jet, and (3) by minute variations in the dimensionai relationship of component parts of the jet (such as the distance of the tip of the yarn needle from the restricted orifice, venturi size and shape, needle size and shape, and axial alignment of the needle with respect to the venturi).
- Patent 2,852,906 in which the cap of the yarn needle is threaded upon the body of the jet and the axial distance between the restricted orifice and the tip of the yarn needle is changed by rotation of the yarn needle cap, it has been found that it is necessary to provide a locking mechanism, such as a set screw on the cap threads, to insure that the adjustment will not accidental ly be disturbed during the operation of the texturizing apparatus.
- a locking mechanism such as a set screw on the cap threads
- Still another object of this invention is to provide a method of fabricating a yarn texturing jet wherein the yarn needle is rigidly secured in a fixed position in relation to the annular jet body and the restricted fluid orifice is rigidly and nonadjustably but removably secured to the annular jet body in a fixed and predetermined relationship to the tip of the yarn needle such that assembly and disassembly for cleaning and other servicing does not disturb this fixed and predetermined relationship.
- FIGURE 1 is a view in perspective of an improved texturing jet of the type which may be fabricated by the method of this invention, showing the orifice cap assembled upon the jet body and an air inlet pipe assembled thereon;
- FIGURE 2 is a cross-sectional view taken along line 2-2 of FIGURE 1 and showing, on an enlarged scale, the details of construction of the texturing jet shown in FIGURE 1;
- FIGURE 3 is a plan view of the annular body and hollow yarn needle of the texturing jet shown in FIG- URES 1 and 2, and illustrating the integral unit prior to machining the orifice cap abutting surfaces and yarn needle tip;
- FIGURE 4 schematically illustrates the step of machining the orifice cap abutting surfaces of the annular jet body and the yarn needle tip illustrated in FIGURE 3;
- FIGURE 5 is a side view of the orifice cap included in the texturing jet shown in FIGURES 1 and 2, showing the complementally machined inner surfaces which abut the machined surfaces of the annular jet body;
- FIGURE 6 is a front view of an assembled jet body shown in FIGURE 4 and orifice cap shown in FIGURE 5, this view showing the offset or spaced relationship be tween the axis of the restricted air orifice and the axis of the yarn needle;
- FIGURE 7 is a schematic diagram illustrating a complete yarn texturing apparatus including a takeup device, an improved texturing jet which may be fabricated by the method of this invention, and two separate supply sources of untextured yarn which are to be combined into a single textured or bulked yarn.
- the annular body 10 contains an elongated yarn needle 14 having a radially enlarged base portion 15 which is press-fit or otherwise securely held within the annular body 10.
- the tip 16 of the yarn needle 14 is of reduced diameter and extends from the main body of the yarn needle 14 beyond the open end of the annular body 10.
- the entrance to the axial passageway within the yarn needle 14 (shown at the right of FIGURE 2), is conical or outwardly flared to facilitate threading the untextured yarns through the texturing jet.
- the orifice cap 11 of the illustrated texturing jet comprises a generally flat, disk-like cap member 17 having a central opening or aperture 18 which receives an orifice insert 19 which is press-fit or otherwise securely held therein, as clearly shown in FIGURE 2.
- the orifice insert 19 includes the restricted orifice throat 20 communicating with outwardly flared passages 21 and 22 which complete the yarn and fluid path through the orifice insert 19.
- the open end of the annular body 10 has a generally planar outer face 23 with an annular recess 24 on its radially outer surface.
- the abutting inner face 25 of the orifice cap 11 is generally planar and is terminated by a laterally extending, continuous outer flange 26 which cooperates with the recess 24 in the outer face 23 of the annular body 10 to securely seat the orifice cap 11 upon the annular body 10.
- the bolts 12 pass through bolt holes 27 and 28 in the orifice cap 11 and are threaded into the recesses 13 to securely hold the orifice cap 11 upon the annular body 10.
- a fluid pipe 29, shown in FIGURE 1 is secured within a radially extending air inlet 30 in the annular body 10 and communicates with the air space circumjacent the yarn needle 14.
- FIGURES 3 and 4 schematically show the annular body 10 and yarn needle 14 as they are initially constructed prior to and during a machining step which is of critical importance in the method of fabricating the improved texturing jet of this invention.
- FIGURE 3 schematically shows the annular body 10 with the base portion 15 of the yarn needle 14 press-fit in one end of the annular body 10.
- the cylindrical, annular body 10, in this illustration designated as 10a, and the yarn needle tip 16, designated in this figure as 16a, are not shaped at this stage of fabrication to their final form as illustrated in FIGURE 2.
- the outer face 23 and yarn needle tip 16 are machined by a single forming cutter F, as schematically illustrated in FIGURE 4, which forms the recess 24 and shapes and determines the length of the yarn needle tip 16. It is important to note that because the unitary annular body 10 and yarn needle 14 are machined by a single forming cutter F, the dimensional relationships between the position of the yarn needle tip 16 and the outer face 23 of the annular body 10 will be constant for any number of units machined by this forming cutter F.
- FIGURE 5 is a side view of the orifice cap 11 with the orifice insert 19 press-fit therein.
- the inner face 25 of the cap member 17 is machined to be complementary in shape to the forming cutter F, illustrated in FIGURE 4.
- a single forming cutter complementary in shape to cutter F may be used.
- the central opening 18 in the orifice cap member 17 is drilled and has a diameter large enough to receive the orifice insert 19 which is press-fit therein.
- the central opening 18 is carefully positioned so that the restricted orifice throat 20 will be in a predetermined relationship with the axis of the yarn needle 14.
- the central opening 18 may be positioned 50 that it is concentric or nonconcentric in the cap member 17, as desired, and therefore, will be coaxial or offset from the yarn needle 14 when the orifice cap 11 is secured to the annular body 10.
- the use of a drilling jig insures a constant dimensional relationship between the orifice throat 20 and the axis of the yarn needle 14 throughout a given series of jets.
- the final step in fabrication of the improved texturing jet of this invention is to press-fit the orifice insert 19 in position for uniform flow and texturing characteristics.
- the positon of the orifice throat 20 with respect to the axis of the yarn needle 14 is fixed by the location of the central opening 18.
- the axial distance from the orifice throat 20 to the tip of the yarn needle 14 is also important and should be uniform throughout a given series of jets. This uniformity is attained by use of a flow meter connected in series with the orifice throat 20 which, by adjustment, of the axial position of the orifice cap 17, will indicate the flow and texturing characteristics of that jet.
- FIGURE 7 schematically illustrates a complete yarn bulking apparatus including the improved texturing jet which may be fabricated by the method of this invention.
- Two yarn supply packages, 31 and 32 provide, for example, a source of core yarn 33 and effect yarn 34.
- Yarns 33 and 34 are drawn upwardly over guiding and tension rollers 35 and 36 by pairs of feed rolls 37, 38, 39 and 40.
- Motor and control means 41 and 42 provide a variable speed control of the feed rolls 37, 38, 39 and 40, respectively.
- the feed speed of the core yarn 33 and effect yarn 34 may be variably adjusted in relation to each other and in relation to the takeup speed of the bulked composite yarn 43.
- the core yarn 33 and effect yarn 34 are passed through a series of guide eyes 44, 45 and 46 which lead the core and effect yarns 33 and 34 to the, improved texturing jet of this invention which is supplied with air under pressure through the air pipe 29.
- the bulked, composite yam 43 leaving the texturing jet is passed around a guide wheel 47, past a conventional traversing device 48 which directs the yarn back and forth across the package 49.
- a constant yarn takeup speed is obtained by driving the yarn package 49 by frictional contact with a power roll 50 which is driven by a driving mechanism 51.
- the increased diameter of the package 49 from the buildup of yarn does not increase the takeup speed due to the fact that the power for driving the package 49 is derived solely from frictional contact with the surface of the yarn itself by the power roll 50.
- the dimensional relationships between the components of the texturing jet, particularly the distance between the axes of the yarn needle 14 and the orifice throat 20 are of critical importance in producing a composite, bulked yarn of desired characteristics. Because there are many variables which must be accurately controlled in producing such yarns, it is the primary object of this invention to provide a method of fabricating a series of texturing jets having the identical dimensional relationships mentioned above.
- a given bulked yarn may be produced throughout a series of texturing installations such as that schematically shown in FIGURE 7 through use of identical texturing jets and the identical adjustment of the feed speed of the core and effect yarns 33 and 34 in relation to the takeup speed of the bulked composite yarn 43.
- An inherent advantage in the improved unitary jet produced by the method of this invention is the fact that it may be assembled and disassembled by the operator of the texturing apparatus quickly and conveniently by removal and replacement of the bolts 12 which hold the orifice cap 11 to the annular body 10. Because these pieces are accurately machined to mate with one another in a preestablished relationship, there is no adjustment needed subsequent to cleaning or other servicing.
- a method of producing a series of fluid nozzles for yarn texturing, each nozzle within said series having identical fixed dimensional relationships comprising the steps of (1) fabricating an annular body including a yarn needle rigidly secured at one end of said body and extending toward the other end of said body, (2) forming the tip of said yarn needle and said other end of said annular body with a first shaped cutting tool to provide a fixed dimensional relationship therebetween, (3) forming the inner surfaces of a venturi cap with a second shaped cutting tool to provide a complementary inner surface to be associated with said other end of said annular body to provide a fixed dimensional relationship therewith and with said tip of said needle, (4) positioning a restricted fluid orifice in said venturi cap with the axis of said orifice parallel to the axis of said yarn needle when said venturi cap and said annular body are rigidly secured to one another, and (5) securing said venturi cap upon said other end of said annular body such that their complementally formed surfaces insure a fixed dimensional relationship therebetween.
- a method of producing a series of fluid nozzles for yarn texturing, each nozzle within said series having identical fixed dimensional relationships comprising the steps of (1) fabricating an annular body including a yarn needle rigidly secured at one end of said body and extending toward the other end of said body, (2) machining the tip of said yarn needle and said other end of said annular body with a single cutting tool to provide a fixed dimensional relationship therebetween, (3) machining the inner surfaces of a venturi cap to provide a complementary inner surface to be associated with said other end of said annular body, (4) forming an orifice insert aperture in said venturi cap in a predetermined dimensional relationship with the axis of said yarn needle, (5 securing said venturi cap upon said other end of said annular body, and (6) positioning an orifice insert having a restricted fluid venturi within said aperture in a predetermined dimensional relationship with the tip of said yarn needle whereby the fluid flow, at a given fluid pressure through said fluid nozzles will be uniform throughout said series of fluid nozzles.
