Definitions

  • This invention relates to an apparatus for texturing yarn.
  • Shichman and Siegel US. patent application Ser. No. 373,686, filed June 9, 1964 of common ownership there is disclosed an apparatus for texturing yarn in which the yarn to be textured is jetted into a nip formed between a pair of rotatable rolls each having a roughened yarn contacting surface.
  • one roll has flanges at either side projecting radially beyond its yarn contacting surface and which are adapted to receive the surface of the other roll therebetween.
  • the flanges have a multiplicity of holes therethrough through which the jetting medium may escape.
  • This invention relates to a texturing apparatus of this type having holes through its flanges.
  • the holes through at least one, and preferably both, flanges open at their interior ends into a manifold groove in the flange which is common to all the holes through that flange.
  • the groove is covered at the inner face of the flange with a flat screen having relatively small openings therethrough.
  • the jetting medium escapes to the atmosphere through the screens to the manifold groove, and thence out the holes through the flange.
  • Yarn textured on this apparatus exhibits an improved crimp and may be processed with less tangling.
  • FIG. 1 is schematic elevational view of a yarn texturing apparatus
  • FIG. 2 is a section of a flanged roll of the apparatus along the line 2-2 of FIG. 1, and
  • FIG. 3 is an exploded perspective view of the elements of the flanged roll of FIG. 2.
  • the apparatus of this invention is arranged to texturize yarn, for example a continuous filament, multi-filament polypropylene olefin yarn, as it is received from draw rolls as in the aforesaid Shichman et a l. application.
  • Yarn Y is delivered to a first pair of godet rolls 10, 11, and thence to a second pair 12, 13.
  • each pair of godet rolls consist of a relatively large roll or 12 and a relatively small roll 11 or 13 with the two rolls in a pair arranged at an axis angle to each other so as to advance yarn in a series of spaced loops about the pair.
  • Yarn Y is wrapped six to eight times about each pair of driven godet rolls, and is advanced from the last pair 12, 13 to a texturing apparatus.
  • an undrawn yarn Y is drawn between the two pair of godet rolls.
  • roll 10 is heated to 200- 250 F. and is rotated at a surface speed of 250 per minute, while roll 12, heated to a temperature of 200 to 350 F., is rotated at a surface speed of 1,000 per minute to draw the yarn Y 4 to 1 between the pairs of rolls.
  • the drawn yarn next enters the steam propulsion device indicated generally at 14 which is of the type disclosed in the Shichman et al. application to which reference should be had for a detailed explanation of its operation.
  • the discharge tip of steam propulsion device 14 fits 3,367,005 Patented Feb. 6, 1968 closely into the nip of a pair of rolls, 35, 36 rotatably driven in the direction indicated by the arrows in FIG. 1.
  • this projection is shown spaced a substantial distance from the point of nearest approach of rolls 35, 36 to each other, this spacing has been exaggerated for the purpose of clarity, and it will be understood that this projection has a lower tapered edge that projects into the nip and the arcuate surfaces of this projection are arranged as close to rolls 35, 36 as'can conveniently be obtained.
  • rolls 35 and 36 each have a multiplicity of gear tooth-like projections and indentations disposed around their entire peripheries.
  • the rolls 35, 36 are equipped with gear tooth-like projections and indentations, these teeth do not mesh; rather the closest approach of the circular path followed by the radially outermost surface of the teeth on roll 35 as this roll rotates about its axis is spaced from the similar path of the teeth on roll 36 a little distance but not far enough to lose com pressive force on the yarn.
  • These paths should not' be so close to each other as to lose driving force generated by the steam on the yarn.
  • roll 36 is provided with flanges 37, 38 which project beyond the roughened surface of roll 36 proper at each side thereof and which snugly receive the sides of roll 35 and the discharge tip of steam propulsion device 14 to enclose the space between this tip and rolls 35, 36.
  • Flanges 37, 38 have a multiplicity of holes 39, 39' therethrough as will be described in detail hereinafter.
  • the yarn may be withdrawn from rolls 35, 36 by an aspirator indicated generally at 40. After the yarn leaves air quench aspirator 40, it passes around a pulley 46 and is directed to a first pair of driven draw out rolls 47, 48 and thence to a second pair of draw out rolls 49, 50 driven at a slightly faster speed than the first pair 47 48.
  • flanges 37, 38 have been modified from that disclosed in the aforsaid Shichman et al. application. These modified flanges are shown in greater detail in FIGS. 2 and 3.
  • Flange 37 is generally similar to flange 38 in the preferred embodiment shown in the drawing, and accordingly a description of flange 38 will suflice for an understanding of the construction of both flanges.
  • Roll 36 has the usual central portion 51 having a roughened surface formed by a multiplicity of gear toothlike projections and identations disposed around its entire periphery.
  • Flange 38 has a manifold groove 52 in the disc like member 55.
  • this groove 52 is a segment of a circle in cross-section and is circular in plan.
  • Manifold groove 52 is disposed a short distance radially outwardly of the roughened surface of central portion 51 yet opens into the space into which yarn Y is propelled.
  • This groove 52 is open throughout its length at the inner face of flange 38, and hence when the rolls are assembled it is in free communication, except for the yarn restraining screen to be described, with the space into which the yarn is propelled at the nip.
  • Each hole 39 extends through flange 38 axially of roll 36 and opens at its internal end into this manifold groove.
  • the groove 52 is covered at the inner face of flange 38 with a flat relatively fine mesh yarn restraining screen 53 which is held in place by a ring 54.
  • Screen 53 readily passes the fluid medium propelling the yarn but does not permit the fibers of the yarn to pass therethrough to a substantial extent
  • screen 53 originally is an annulus with its outer diameter slightly larger than the circular outer diameter of disc-like member 55.
  • the internal diameter of screen annulus 53 in the embodiment shown is substantially less than the outer diameter of the roughened surface of the central portion 51 of the roll.
  • the internal diameter of the screen annulus 53 may be only slightly smaller than the diameter of the circle 57 formed by the innermost edge of manifold groove 52 as necessary to completely cover this groove.
  • a ring 54 holds screen 53 in place.
  • Ring 54 has an internal diameter such that it may be press-fit onto the outer periphery of disc 55 when a turned down lip 56 of screen 53 is sandwiched between ring 54 and disc 55.
  • flange 37 is constructed similarly to flange 38.
  • the holes 39' through flange 37 open at their internal ends into a manifold groove 52' in the inner face of flange 37, and a screen 53, held in place by a ring 54 on the disc 55, covers groove 52'.
  • Disc 55, screen 53 and ring '54 are assembled by first positioning screen annulus 53 over groove 52 and on disc 55 substantially concentrically with disc 55 so lip 56 overhangs the edges of disc 55. Thereafter ring 54 is pressed onto disc '55 over overhanging lip 56 of screen 53 with a press-fit in much the same way a drum-head is applied.
  • each of the manifold grooves 52, 52' had a cross-section radius of and was deep.
  • Each flange has one hundred fifty of the bores 39, each about .08" in diameter that opened into its manifold groove with their centers evenly spaced from each other on a circle about A of the distance from the teeth to the periphery of the flange.
  • a yarn texturing apparatus in which yarn is textured by propelling the same with a fluid medium into a nip formed by two rolls, the improvement which comprises a first roll having axially spaced flanges adapted to receive a second roll therebetween when said first and second rolls are in nip relation, at least one of said flanges having a manifold groove at its axially inner face positioned to be in substantially free communication with the space into which the yarn is propelled, said flange also having a plurality of vent holes opening into said manifold groove, and a screen covering said groove at said axially inner face, whereby the fluid medium, at least in part, may pass through said screen into said manifold groove and be vented through said holes.
  • each flange has a manifold groove extending entirely around the periphery of the flange, each said flange having a multiplicity of small closely spaced bores passing through said flange and opennig into said manifold groove.
  • each said flange comprises a circular disc containing said manifold groove and said bores, and in which said screen is an annulus having its outer lip bent over the outer periphery of said disc, and a ring press-fit over said lip and disc holding said screen to said disc.
